Introduction
|
2014-12-15 20:59:20 +01:00
|
|
|
|
------------
|
2012-03-22 11:14:04 +01:00
|
|
|
|
Content and functionality can be added to Minetest 0.4 by using Lua
|
|
|
|
|
scripting in run-time loaded mods.
|
|
|
|
|
|
|
|
|
|
A mod is a self-contained bunch of scripts, textures and other related
|
|
|
|
|
things that is loaded by and interfaces with Minetest.
|
|
|
|
|
|
|
|
|
|
Mods are contained and ran solely on the server side. Definitions and media
|
|
|
|
|
files are automatically transferred to the client.
|
|
|
|
|
|
|
|
|
|
If you see a deficiency in the API, feel free to attempt to add the
|
|
|
|
|
functionality in the engine and API. You can send such improvements as
|
|
|
|
|
source code patches to <celeron55@gmail.com>.

Startup
|
2014-12-15 20:59:20 +01:00
|
|
|
|
-------
|
2012-03-22 11:14:04 +01:00
|
|
|
|
Mods are loaded during server startup from the mod load paths by running
|
2014-12-15 20:59:20 +01:00
|
|
|
|
the `init.lua` scripts in a shared environment.

Games
|
|
|
|
|
-----
|
|
|
|
|
Games are looked up from:
|
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
* `$path_share/games/gameid/`
|
|
|
|
|
* `$path_user/games/gameid/`
|
|
|
|
|
|
|
|
|
|
where `gameid` is unique to each game.
|
|
|
|
|
|
|
|
|
|
The game directory contains the file `game.conf`, which contains these fields:
|
|
|
|
|
|
|
|
|
|
name = <Human-readable full name of the game>
|
|
|
|
|
|
2014-07-05 12:19:55 +02:00
|
|
|
|
e.g.
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
|
|
|
|
name = Minetest
|
2013-03-21 19:04:00 +01:00
|
|
|
|
|
2013-03-21 20:42:23 +01:00
|
|
|
|
The game directory can contain the file minetest.conf, which will be used
|
|
|
|
|
to set default settings when running the particular game.
|
2015-10-18 10:41:52 +02:00
|
|
|
|
It can also contain a settingtypes.txt in the same format as the one in builtin.
|
2016-06-07 04:23:23 +02:00
|
|
|
|
This settingtypes.txt will be parsed by the menu and the settings will be displayed
|
|
|
|
|
in the "Games" category in the settings tab.
|
2013-03-21 20:42:23 +01:00

### Menu images
|
|
|
|
|
|
2016-06-07 04:23:23 +02:00
|
|
|
|
Games can provide custom main menu images. They are put inside a `menu` directory
|
|
|
|
|
inside the game directory.
|
2015-07-21 17:17:46 +02:00
|
|
|
|
|
2016-06-07 04:23:23 +02:00
|
|
|
|
The images are named `$identifier.png`, where `$identifier` is
|
|
|
|
|
one of `overlay,background,footer,header`.
|
|
|
|
|
If you want to specify multiple images for one identifier, add additional images named
|
|
|
|
|
like `$identifier.$n.png`, with an ascending number $n starting with 1, and a random
|
|
|
|
|
image will be chosen from the provided ones.

Mod load path
|
|
|
|
|
-------------
|
|
|
|
|
Generic:
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
|
|
|
|
* `$path_share/games/gameid/mods/`
|
|
|
|
|
* `$path_share/mods/`
|
|
|
|
|
* `$path_user/games/gameid/mods/`
|
|
|
|
|
* `$path_user/mods/` (User-installed mods)
|
|
|
|
|
* `$worldpath/worldmods/`
|
2012-03-22 10:41:40 +01:00
|
|
|
|
|
2014-07-05 12:19:55 +02:00
|
|
|
|
In a run-in-place version (e.g. the distributed windows version):
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
|
|
|
|
* `minetest-0.4.x/games/gameid/mods/`
|
|
|
|
|
* `minetest-0.4.x/mods/` (User-installed mods)
|
|
|
|
|
* `minetest-0.4.x/worlds/worldname/worldmods/`
|
2012-03-22 10:41:40 +01:00
|
|
|
|
|
2014-07-05 12:19:55 +02:00
|
|
|
|
On an installed version on Linux:
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
|
|
|
|
* `/usr/share/minetest/games/gameid/mods/`
|
|
|
|
|
* `$HOME/.minetest/mods/` (User-installed mods)
|
|
|
|
|
* `$HOME/.minetest/worlds/worldname/worldmods`
|
2012-03-22 10:41:40 +01:00
|
|
|
|
|
2012-04-08 22:32:53 +02:00
|
|
|
|
Mod load path for world-specific games
|
|
|
|
|
--------------------------------------
|
|
|
|
|
It is possible to include a game in a world; in this case, no mods or
|
|
|
|
|
games are loaded or checked from anywhere else.
|
|
|
|
|
|
2014-07-05 12:19:55 +02:00
|
|
|
|
This is useful for e.g. adventure worlds.
|
2012-04-08 22:32:53 +02:00
|
|
|
|
|
|
|
|
|
This happens if the following directory exists:
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
|
|
|
|
$world/game/
|
2012-04-08 22:32:53 +02:00
|
|
|
|
|
|
|
|
|
Mods should be then be placed in:
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
|
|
|
|
$world/game/mods/
|
2012-04-08 22:32:53 +02:00
|
|
|
|
|
2012-05-21 18:49:35 +02:00
|
|
|
|
Modpack support
|
|
|
|
|
----------------
|
|
|
|
|
Mods can be put in a subdirectory, if the parent directory, which otherwise
|
2014-12-15 20:59:20 +01:00
|
|
|
|
should be a mod, contains a file named `modpack.txt`. This file shall be
|
|
|
|
|
empty, except for lines starting with `#`, which are comments.
|
2012-05-21 18:49:35 +02:00

|
|
|
|
|
`-- another
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
### modname
|
|
|
|
|
The location of this directory can be fetched by using
|
|
|
|
|
`minetest.get_modpath(modname)`.
|
|
|
|
|
|
|
|
|
|
### `depends.txt`
|
|
|
|
|
List of mods that have to be loaded before loading this mod.
|
|
|
|
|
|
|
|
|
|
A single line contains a single modname.
|
|
|
|
|
|
|
|
|
|
Optional dependencies can be defined by appending a question mark
|
|
|
|
|
to a single modname. Their meaning is that if the specified mod
|
|
|
|
|
is missing, that does not prevent this mod from being loaded.
|
|
|
|
|
|
|
|
|
|
### `screenshot.png`
|
2016-07-25 22:52:42 +02:00
|
|
|
|
A screenshot shown in the mod manager within the main menu. It should
|
|
|
|
|
have an aspect ratio of 3:2 and a minimum size of 300×200 pixels.
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
|
|
|
|
### `description.txt`
|
|
|
|
|
A File containing description to be shown within mainmenu.
|
|
|
|
|
|
2015-10-18 10:41:52 +02:00
|
|
|
|
### `settingtypes.txt`
|
|
|
|
|
A file in the same format as the one in builtin. It will be parsed by the
|
|
|
|
|
settings menu and the settings will be displayed in the "Mods" category.
|
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
### `init.lua`
|
|
|
|
|
The main Lua script. Running this script should register everything it
|
|
|
|
|
wants to register. Subsequent execution depends on minetest calling the
|
|
|
|
|
registered callbacks.
|
|
|
|
|
|
2014-12-12 20:49:19 +01:00
|
|
|
|
`minetest.settings` can be used to read custom or existing settings at load
|
|
|
|
|
time, if necessary. (See `Settings`)
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
|
|
|
|
### `models`
|
|
|
|
|
Models for entities or meshnodes.
|
|
|
|
|
|
|
|
|
|
### `textures`, `sounds`, `media`
|
|
|
|
|
Media files (textures, sounds, whatever) that will be transferred to the
|
|
|
|
|
client and will be available for use by the mod.
|
2012-03-22 11:14:04 +01:00

|
Naming convention for registered textual names
|
|
|
|
|
----------------------------------------------
|
2012-03-22 11:14:04 +01:00
|
|
|
|
Registered names should generally be in this format:
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
2017-06-02 14:15:49 +02:00
|
|
|
|
`modname:<whatever>`
|
|
|
|
|
|
|
|
|
|
`<whatever>` can have these characters:
|
|
|
|
|
|
|
|
|
|
a-zA-Z0-9_
|
2012-03-22 10:41:40 +01:00
|
|
|
|
|
|
|
|
|
This is to prevent conflicting names from corrupting maps and is
|
|
|
|
|
enforced by the mod loader.
|
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
### Example
|
|
|
|
|
In the mod `experimental`, there is the ideal item/node/entity name `tnt`.
|
|
|
|
|
So the name should be `experimental:tnt`.
|
2012-03-22 10:41:40 +01:00
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
Enforcement can be overridden by prefixing the name with `:`. This can
|
2012-03-22 10:41:40 +01:00
|
|
|
|
be used for overriding the registrations of some other mod.
|
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
Example: Any mod can redefine `experimental:tnt` by using the name
|
2012-03-22 10:41:40 +01:00
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
:experimental:tnt
|
2012-03-22 10:41:40 +01:00
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
when registering it.
|
|
|
|
|
(also that mod is required to have `experimental` as a dependency)
|
|
|
|
|
|
|
|
|
|
The `:` prefix can also be used for maintaining backwards compatibility.
|
|
|
|
|
|
|
|
|
|
### Aliases
|
2016-07-10 15:15:43 +02:00
|
|
|
|
Aliases can be added by using `minetest.register_alias(name, convert_to)` or
|
2017-06-02 14:15:49 +02:00
|
|
|
|
`minetest.register_alias_force(name, convert_to)`.
|
2012-03-22 10:41:40 +01:00
|
|
|
|
|
2012-03-22 11:14:04 +01:00
|
|
|
|
This will make Minetest to convert things called name to things called
|
2014-12-15 20:59:20 +01:00
|
|
|
|
`convert_to`.
|
2012-03-22 11:14:04 +01:00
|
|
|
|
|
2016-07-10 15:15:43 +02:00
|
|
|
|
The only difference between `minetest.register_alias` and
|
|
|
|
|
`minetest.register_alias_force` is that if an item called `name` exists,
|
|
|
|
|
`minetest.register_alias` will do nothing while
|
|
|
|
|
`minetest.register_alias_force` will unregister it.
|
|
|
|
|
|
2012-03-22 10:41:40 +01:00
|
|
|
|
This can be used for maintaining backwards compatibility.
|
|
|
|
|
|
2014-07-05 12:19:55 +02:00
|
|
|
|
This can be also used for setting quick access names for things, e.g. if
|
2014-12-15 20:59:20 +01:00
|
|
|
|
you have an item called `epiclylongmodname:stuff`, you could do
|
|
|
|
|
|
|
|
|
|
minetest.register_alias("stuff", "epiclylongmodname:stuff")
|
|
|
|
|
|
|
|
|
|
and be able to use `/giveme stuff`.
|
2012-03-22 10:41:40 +01:00
|
|
|
|
|
|
|
|
|
Textures
|
|
|
|
|
--------
|
2014-12-15 20:59:20 +01:00
|
|
|
|
Mods should generally prefix their textures with `modname_`, e.g. given
|
|
|
|
|
the mod name `foomod`, a texture could be called:
|
|
|
|
|
|
|
|
|
|
foomod_foothing.png
|
2012-03-22 10:41:40 +01:00
|
|
|

Textures are referred to by their complete name, or alternatively by
|
|
|
|
|
stripping out the file extension:

Texture modifiers
|
|
|
|
|
-----------------
|
|
|
|
|
There are various texture modifiers that can be used
|
|
|
|
|
to generate textures on-the-fly.
|
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
### Texture overlaying
|
|
|
|
|
Textures can be overlaid by putting a `^` between them.
|
|
|
|
|
|
|
|
|
|
Example:
|
|
|
|
|
|
|
|
|
|
default_dirt.png^default_grass_side.png
|
|
|
|
|
|
|
|
|
|
`default_grass_side.png` is overlayed over `default_dirt.png`.
|
2016-06-07 04:23:23 +02:00
|
|
|
|
The texture with the lower resolution will be automatically upscaled to
|
|
|
|
|
the higher resolution texture.
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
|
|
|
|
### Texture grouping
|
|
|
|
|
Textures can be grouped together by enclosing them in `(` and `)`.
|
|
|
|
|
|
|
|
|
|
Example: `cobble.png^(thing1.png^thing2.png)`
|
|
|
|
|
|
|
|
|
|
A texture for `thing1.png^thing2.png` is created and the resulting
|
2016-09-03 17:53:15 +02:00
|
|
|
|
texture is overlaid on top of `cobble.png`.
|
|
|
|
|
|
|
|
|
|
### Escaping
|
|
|
|
|
Modifiers that accept texture names (e.g. `[combine`) accept escaping to allow
|
|
|
|
|
passing complex texture names as arguments. Escaping is done with backslash and
|
|
|
|
|
is required for `^` and `:`.
|
|
|
|
|
|
|
|
|
|
Example: `cobble.png^[lowpart:50:color.png\^[mask\:trans.png`
|
|
|
|
|
|
|
|
|
|
The lower 50 percent of `color.png^[mask:trans.png` are overlaid
|
|
|
|
|
on top of `cobble.png`.
|

|
|
|
|
|
|
|
|
|
### Advanced texture modifiers

|
|
#### `[crack:<n>:<p>`
|
|
|
|
|
* `<n>` = animation frame count
|
|
|
|
|
* `<p>` = current animation frame
|
|
|
|
|
|
|
|
|
|
Draw a step of the crack animation on the texture.
|
|
|
|
|
|
|
|
|
|
Example:
|
|
|
|
|
|
|
|
|
|

|
|
* `<h>` = height
|
2016-01-02 22:14:09 +01:00

|
|
|
0 means totally transparent. 255 means totally opaque.
|
2016-07-02 17:58:08 +02:00
|
|
|
|
|
|
|
|
|
Example:

|
|
|
|
Creates an inventorycube with `grass.png`, `dirt.png^grass_side.png` and
|
|
|
|
|
`dirt.png^grass_side.png` textures
|
|
|
|
|
|
|
|
|
|
#### `[lowpart:<percent>:<file>`
|
|
|
|
|
Blit the lower `<percent>`% part of `<file>` on the texture.
|
|
|
|
|
|
|
|
|
|
Example:
|
|
|
|
|
|
|
|
|
|

#### `[verticalframe:<t>:<n>`
|
|
|
|
|
* `<t>` = animation frame count
|
|
|
|
|
* `<n>` = current animation frame
|
|
|
|
|
|
|
|
|
|
Crops the texture to a frame of a vertical animation.
|
|
|
|
|
|
|
|
|
|
Example:
|
|
|
|
|
|

#### `[mask:<file>`
|
|
|
|

|
|
|
|
2014-09-23 14:39:34 +02:00
|
|
|
|
#### `[sheet:<w>x<h>:<x>,<y>`
|
|
|
|
|
Retrieves a tile at position x,y from the base image
|
|
|
|
|
which it assumes to be a tilesheet with dimensions w,h.
|
|
|
|
|
|
|

|
|
|
#### `[colorize:<color>:<ratio>`
|
2014-12-15 20:59:20 +01:00
|
|
|
|
Colorize the textures with the given color.
|
|
|
|
|
`<color>` is specified as a `ColorString`.
|
2016-04-03 08:35:42 +02:00
|
|
|
|
`<ratio>` is an int ranging from 0 to 255 or the word "`alpha`". If
|
|
|
|
|
it is an int, then it specifies how far to interpolate between the
|
|
|
|
|
colors where 0 is only the texture color and 255 is only `<color>`. If
|
|
|
|
|
omitted, the alpha of `<color>` will be used as the ratio. If it is
|
2016-04-06 09:38:11 +02:00
|
|
|
|
the word "`alpha`", then each texture pixel will contain the RGB of
|
|
|
|
|
`<color>` and the alpha of `<color>` multiplied by the alpha of the
|
|
|
|
|
texture pixel.

|
|
|
|
#### `[multiply:<color>`
|
|
|
|
|
Multiplies texture colors with the given color.
|
|
|
|
|
`<color>` is specified as a `ColorString`.
|
|
|
|
|
Result is more like what you'd expect if you put a color on top of another
|
|
|
|
|
color. Meaning white surfaces get a lot of your new color while black parts don't
|
|
|
|
|
change very much.

Hardware coloring
|
|
|
|
|
-----------------
|
|
|
|
|
The goal of hardware coloring is to simplify the creation of
|
|
|
|
|
colorful nodes. If your textures use the same pattern, and they only
|
|
|
|
|
differ in their color (like colored wool blocks), you can use hardware
|
|
|
|
|
coloring instead of creating and managing many texture files.
|
|
|
|
|
All of these methods use color multiplication (so a white-black texture
|
|
|
|
|
with red coloring will result in red-black color).
|
|
|
|
|
|
|
|
|
|
### Static coloring
|
|
|
|
|
This method is useful if you wish to create nodes/items with
|
|
|
|
|
the same texture, in different colors, each in a new node/item definition.
|
|
|
|
|
|
|
|
|
|
#### Global color
|
|
|
|
|
When you register an item or node, set its `color` field (which accepts a
|
|
|
|
|
`ColorSpec`) to the desired color.
|
|
|
|
|
|
|
|
|
|
An `ItemStack`s static color can be overwritten by the `color` metadata
|
|
|
|
|
field. If you set that field to a `ColorString`, that color will be used.
|
|
|
|
|
|
|
|
|
|
#### Tile color
|
|
|
|
|
Each tile may have an individual static color, which overwrites every
|
|
|
|
|
other coloring methods. To disable the coloring of a face,
|
|
|
|
|
set its color to white (because multiplying with white does nothing).
|
|
|
|
|
You can set the `color` property of the tiles in the node's definition
|
|
|
|
|
if the tile is in table format.
|
|
|
|
|
|
|
|
|
|
### Palettes
|
|
|
|
|
For nodes and items which can have many colors, a palette is more
|
|
|
|
|
suitable. A palette is a texture, which can contain up to 256 pixels.
|
|
|
|
|
Each pixel is one possible color for the node/item.
|
|
|
|
|
You can register one node/item, which can have up to 256 colors.
|
|
|
|
|
|
|
|
|
|
#### Palette indexing
|
|
|
|
|
When using palettes, you always provide a pixel index for the given
|
|
|
|
|
node or `ItemStack`. The palette is read from left to right and from
|
|
|
|
|
top to bottom. If the palette has less than 256 pixels, then it is
|
|
|
|
|
stretched to contain exactly 256 pixels (after arranging the pixels
|
|
|
|
|
to one line). The indexing starts from 0.
|
|
|
|
|
|
|
|
|
|
Examples:
|
|
|
|
|
* 16x16 palette, index = 0: the top left corner
|
|
|
|
|
* 16x16 palette, index = 4: the fifth pixel in the first row
|
|
|
|
|
* 16x16 palette, index = 16: the pixel below the top left corner
|
|
|
|
|
* 16x16 palette, index = 255: the bottom right corner
|
|
|
|
|
* 2 (width)x4 (height) palette, index=31: the top left corner.
|
|
|
|
|
The palette has 8 pixels, so each pixel is stretched to 32 pixels,
|
|
|
|
|
to ensure the total 256 pixels.
|
|
|
|
|
* 2x4 palette, index=32: the top right corner
|
|
|
|
|
* 2x4 palette, index=63: the top right corner
|
|
|
|
|
* 2x4 palette, index=64: the pixel below the top left corner
|
|
|
|
|
|
|
|
|
|
#### Using palettes with items
|
|
|
|
|
When registering an item, set the item definition's `palette` field to
|
|
|
|
|
a texture. You can also use texture modifiers.
|
|
|
|
|
|
|
|
|
|
The `ItemStack`'s color depends on the `palette_index` field of the
|
|
|
|
|
stack's metadata. `palette_index` is an integer, which specifies the
|
|
|
|
|
index of the pixel to use.
|
|
|
|
|
|
|
|
|
|
#### Linking palettes with nodes
|
|
|
|
|
When registering a node, set the item definition's `palette` field to
|
|
|
|
|
a texture. You can also use texture modifiers.
|
|
|
|
|
The node's color depends on its `param2`, so you also must set an
|
|
|
|
|
appropriate `drawtype`:
|
|
|
|
|
* `drawtype = "color"` for nodes which use their full `param2` for
|
|
|
|
|
palette indexing. These nodes can have 256 different colors.
|
|
|
|
|
The palette should contain 256 pixels.
|
|
|
|
|
* `drawtype = "colorwallmounted"` for nodes which use the first
|
|
|
|
|
five bits (most significant) of `param2` for palette indexing.
|
|
|
|
|
The remaining three bits are describing rotation, as in `wallmounted`
|
|
|
|
|
draw type. Division by 8 yields the palette index (without stretching the
|
|
|
|
|
palette). These nodes can have 32 different colors, and the palette
|
|
|
|
|
should contain 32 pixels.
|
|
|
|
|
Examples:
|
|
|
|
|
* `param2 = 17` is 2 * 8 + 1, so the rotation is 1 and the third (= 2 + 1)
|
|
|
|
|
pixel will be picked from the palette.
|
|
|
|
|
* `param2 = 35` is 4 * 8 + 3, so the rotation is 3 and the fifth (= 4 + 1)
|
|
|
|
|
pixel will be picked from the palette.
|
|
|
|
|
* `drawtype = "colorfacedir"` for nodes which use the first
|
|
|
|
|
three bits of `param2` for palette indexing. The remaining
|
|
|
|
|
five bits are describing rotation, as in `facedir` draw type.
|
|
|
|
|
Division by 32 yields the palette index (without stretching the
|
|
|
|
|
palette). These nodes can have 8 different colors, and the
|
|
|
|
|
palette should contain 8 pixels.
|
|
|
|
|
Examples:
|
|
|
|
|
* `param2 = 17` is 0 * 32 + 17, so the rotation is 17 and the
|
|
|
|
|
first (= 0 + 1) pixel will be picked from the palette.
|
|
|
|
|
* `param2 = 35` is 1 * 32 + 3, so the rotation is 3 and the
|
|
|
|
|
second (= 1 + 1) pixel will be picked from the palette.
|
|
|
|
|
|
|
|
|
|
To colorize a node on the map, set its `param2` value (according
|
|
|
|
|
to the node's draw type).
|
|
|
|
|
|
|
|
|
|
### Conversion between nodes in the inventory and the on the map
|
|
|
|
|
Static coloring is the same for both cases, there is no need
|
|
|
|
|
for conversion.
|
|
|
|
|
|
|
|
|
|
If the `ItemStack`'s metadata contains the `color` field, it will be
|
|
|
|
|
lost on placement, because nodes on the map can only use palettes.
|

If the `ItemStack`'s metadata contains the `palette_index` field, it is
|
|
|
|
|
automatically transferred between node and item forms by the engine,
|
|
|
|
|
when a player digs or places a colored node.
|
|
|
|
|
You can disable this feature by setting the `drop` field of the node
|
|
|
|
|
to itself (without metadata).

### Colored items in craft recipes
|
|
|
|
|
Craft recipes only support item strings, but fortunately item strings
|
|
|
|
|
can also contain metadata. Example craft recipe registration:
|
|
|
|
|
|
|
|
|
|
minetest.register_craft({
|
2017-06-24 20:15:09 +02:00
|
|
|
|
output = minetest.itemstring_with_palette("wool:block", 3),
|
2017-06-02 15:57:59 +02:00
|
|
|
|
type = "shapeless",
|
|
|
|
|
recipe = {
|
|
|
|
|
"wool:block",
|
|
|
|
|
"dye:red",
|
|
|
|
|
},
|
|
|
|
|
})
|
|
|
|
|
|
2017-06-24 20:15:09 +02:00
|
|
|
|
To set the `color` field, you can use `minetest.itemstring_with_color`.
|
|
|
|
|
|
2017-06-02 15:57:59 +02:00
|
|
|
|
Metadata field filtering in the `recipe` field are not supported yet,
|
|
|
|
|
so the craft output is independent of the color of the ingredients.
|
|
|

|
Soft texture overlay
|
|
|
|
|
--------------------
|
|
|
|
|
Sometimes hardware coloring is not enough, because it affects the
|
|
|
|
|
whole tile. Soft texture overlays were added to Minetest to allow
|
|
|
|
|
the dynamic coloring of only specific parts of the node's texture.
|
|
|
|
|
For example a grass block may have colored grass, while keeping the
|
|
|
|
|
dirt brown.
|
|
|
|
|
|
|
|
|
|
These overlays are 'soft', because unlike texture modifiers, the layers
|
|
|
|
|
are not merged in the memory, but they are simply drawn on top of each
|
|
|
|
|
other. This allows different hardware coloring, but also means that
|
|
|
|
|
tiles with overlays are drawn slower. Using too much overlays might
|
|
|
|
|
cause FPS loss.
|
|
|
|
|
|
|
|
|
|
To define an overlay, simply set the `overlay_tiles` field of the node
|
|
|
|
|
definition. These tiles are defined in the same way as plain tiles:
|
|
|
|
|
they can have a texture name, color etc.
|
|
|
|
|
To skip one face, set that overlay tile to an empty string.
|
|
|
|
|
|
|
|
|
|
Example (colored grass block):
|
|
|
|
|
|
|
|
|
|
minetest.register_node("default:dirt_with_grass", {
|
|
|
|
|
description = "Dirt with Grass",
|
|
|
|
|
-- Regular tiles, as usual
|
|
|
|
|
-- The dirt tile disables palette coloring
|
2015-02-27 20:51:55 +01:00
|
|
|
|
tiles = {{name = "default_grass.png"},
|
2017-06-02 15:57:59 +02:00
|
|
|
|
{name = "default_dirt.png", color = "white"}},
|
|
|
|
|
-- Overlay tiles: define them in the same style
|
|
|
|
|
-- The top and bottom tile does not have overlay
|
|
|
|
|
overlay_tiles = {"", "",
|
|
|
|
|
{name = "default_grass_side.png", tileable_vertical = false}},
|
|
|
|
|
-- Global color, used in inventory
|
|
|
|
|
color = "green",
|
|
|
|
|
-- Palette in the world
|
|
|
|
|
paramtype2 = "color",
|
|
|
|
|
palette = "default_foilage.png",
|
|
|
|
|
})

Sounds
|
2014-12-15 20:59:20 +01:00
|
|
|
|
------
|
|
|
|
|
Only Ogg Vorbis files are supported.
|
2012-03-25 15:22:02 +02:00
|
|
|
|
|
|
|
|
|
For positional playing of sounds, only single-channel (mono) files are
|
|
|
|
|
supported. Otherwise OpenAL will play them non-positionally.
|
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
Mods should generally prefix their sounds with `modname_`, e.g. given
|
|
|
|
|
the mod name "`foomod`", a sound could be called:
|
|
|
|
|
|
|
|
|
|
foomod_foosound.ogg
|
2012-03-25 15:22:02 +02:00
|
|
|
|
|
|
|
|
|
Sounds are referred to by their name with a dot, a single digit and the
|
2014-12-15 20:59:20 +01:00
|
|
|
|
file extension stripped out. When a sound is played, the actual sound file
|
2012-03-25 15:22:02 +02:00
|
|
|
|
is chosen randomly from the matching sounds.
|
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
When playing the sound `foomod_foosound`, the sound is chosen randomly
|
2012-03-25 15:22:02 +02:00
|
|
|
|
from the available ones of the following files:
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
|
|
|
|
* `foomod_foosound.ogg`
|
|
|
|
|
* `foomod_foosound.0.ogg`
|
|
|
|
|
* `foomod_foosound.1.ogg`
|
|
|
|
|
* (...)
|
|
|
|
|

2014-07-05 12:19:55 +02:00

Nodes are the bulk data of the world: cubes and other things that take the
|
|
|
|
|
space of a cube. Huge amounts of them are handled efficiently, but they
|
|
|
|
|
are quite static.

Nodes are passed by value between Lua and the engine.
|
|
|
|
|
They are represented by a table:
|
2012-04-07 18:59:03 +02:00
|
|
|
|
|
2014-12-15 20:59:20 +01:00

|
|
{name="name", param1=num, param2=num}
|
|
|
|
|
|
2017-06-02 14:15:49 +02:00
|
|
|
|
`param1` and `param2` are 8-bit integers ranging from 0 to 255. The engine uses
|
|
|
|
|
them for certain automated functions. If you don't use these functions, you can
|
|
|
|
|
use them to store arbitrary values.
|

|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
The functions of `param1` and `param2` are determined by certain fields in the
|
2012-04-07 18:59:03 +02:00
|
|
|
|
node definition:
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
|
|
|
|
`param1` is reserved for the engine when `paramtype != "none"`:
|
|
|
|
|
|
|
|
|
|
paramtype = "light"
|
2015-01-10 08:01:54 +01:00
|
|
|
|
^ The value stores light with and without sun in its upper and lower 4 bits
|
|
|
|
|
respectively. Allows light to propagate from or through the node with
|
|
|
|
|
light value falling by 1 per node. This is essential for a light source
|
|
|
|
|
node to spread its light.
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
|
|
|
|
`param2` is reserved for the engine when any of these are used:
|
|
|
|
|
|
|
|
|
|
liquidtype == "flowing"
|
|
|
|
|
^ The level and some flags of the liquid is stored in param2
|
|
|
|
|
drawtype == "flowingliquid"
|
|
|
|
|
^ The drawn liquid level is read from param2
|
|
|
|
|
drawtype == "torchlike"
|
|
|
|
|
drawtype == "signlike"
|
|
|
|
|
paramtype2 == "wallmounted"
|
|
|
|
|
^ The rotation of the node is stored in param2. You can make this value
|
|
|
|
|
by using minetest.dir_to_wallmounted().
|
|
|
|
|
paramtype2 == "facedir"
|
|
|
|
|
^ The rotation of the node is stored in param2. Furnaces and chests are
|
|
|
|
|
rotated this way. Can be made by using minetest.dir_to_facedir().
|
|
|
|
|
Values range 0 - 23
|
2016-05-10 00:44:15 +02:00
|
|
|
|
facedir / 4 = axis direction:
|
2014-12-15 20:59:20 +01:00
|
|
|
|
0 = y+ 1 = z+ 2 = z- 3 = x+ 4 = x- 5 = y-
|
2016-05-10 00:44:15 +02:00
|
|
|
|
facedir modulo 4 = rotation around that axis
|
2014-12-15 20:59:20 +01:00
|
|
|
|
paramtype2 == "leveled"
|
2015-10-02 23:36:28 +02:00
|
|
|
|
paramtype2 == "degrotate"
|
|
|
|
|
^ The rotation of this node is stored in param2. Plants are rotated this way.
|
|
|
|
|
Values range 0 - 179. The value stored in param2 is multiplied by two to
|
|
|
|
|
get the actual rotation of the node.
|
2015-12-11 07:58:11 +01:00
|
|
|
|
paramtype2 == "meshoptions"
|
|
|
|
|
^ Only valid for "plantlike". The value of param2 becomes a bitfield which can
|
|
|
|
|
be used to change how the client draws plantlike nodes. Bits 0, 1 and 2 form
|
|
|
|
|
a mesh selector. Currently the following meshes are choosable:
|
|
|
|
|
0 = a "x" shaped plant (ordinary plant)
|
|
|
|
|
1 = a "+" shaped plant (just rotated 45 degrees)
|
|
|
|
|
2 = a "*" shaped plant with 3 faces instead of 2
|
|
|
|
|
3 = a "#" shaped plant with 4 faces instead of 2
|
|
|
|
|
4 = a "#" shaped plant with 4 faces that lean outwards
|
|
|
|
|
5-7 are unused and reserved for future meshes.
|
|
|
|
|
Bits 3 through 7 are optional flags that can be combined and give these
|
|
|
|
|
effects:
|
|
|
|
|
bit 3 (0x08) - Makes the plant slightly vary placement horizontally
|
|
|
|
|
bit 4 (0x10) - Makes the plant mesh 1.4x larger
|
|
|
|
|
bit 5 (0x20) - Moves each face randomly a small bit down (1/8 max)
|
|
|
|
|
bits 6-7 are reserved for future use.
|
2017-01-12 15:46:30 +01:00
|
|
|
|
paramtype2 == "color"
|
|
|
|
|
^ `param2` tells which color is picked from the palette.
|
|
|
|
|
The palette should have 256 pixels.
|
|
|
|
|
paramtype2 == "colorfacedir"
|
|
|
|
|
^ Same as `facedir`, but with colors.
|
|
|
|
|
The first three bits of `param2` tells which color
|
|
|
|
|
is picked from the palette.
|
|
|
|
|
The palette should have 8 pixels.
|
|
|
|
|
paramtype2 == "colorwallmounted"
|
|
|
|
|
^ Same as `wallmounted`, but with colors.
|
|
|
|
|
The first five bits of `param2` tells which color
|
|
|
|
|
is picked from the palette.
|
|
|
|
|
The palette should have 32 pixels.
|
2017-03-29 04:40:30 +02:00
|
|
|
|
paramtype2 == "glasslikeliquidlevel"
|
|
|
|
|
^ Only valid for "glasslike_framed" or "glasslike_framed_optional" drawtypes.
|
|
|
|
|
param2 defines 64 levels of internal liquid.
|
|
|
|
|
Liquid texture is defined using `special_tiles = {"modname_tilename.png"},`

Node drawtypes
|
|
|
|
|
---------------
|
2014-09-27 18:16:26 +02:00
|
|
|
|
There are a bunch of different looking node types.
|

|
|
|
|
|
2014-12-15 20:59:20 +01:00

Look for examples in `games/minimal` or `games/minetest_game`.
|
|
|
|
|
|
|
|
|
|
* `normal`
|
|
|
|
|
* `airlike`
|
|

|
|
* `liquid`
|
|
|
|
|
* `flowingliquid`

Node boxes
|
|
|
|
|
-----------
|
|
|
|
|
Node selection boxes are defined using "node boxes"
|
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
The `nodebox` node drawtype allows defining visual of nodes consisting of
|
2012-06-17 16:23:58 +02:00
|
|
|
|
arbitrary number of boxes. It allows defining stuff like stairs. Only the
|
2014-12-15 20:59:20 +01:00
|
|
|
|
`fixed` and `leveled` box type is supported for these.
|
|
|
|
|
|
|
|
|
|
Please note that this is still experimental, and may be incompatibly
|
|
|
|
|
changed in the future.
|
2012-06-17 16:23:58 +02:00
|
|
|
|
|
|
|
|
|
A nodebox is defined as any of:
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
|
|
|
|
{
|
|
|
|
|
-- A normal cube; the default in most things
|
|
|
|
|
type = "regular"
|
|
|
|
|
}
|
|
|
|
|
{
|
|
|
|
|
-- A fixed box (facedir param2 is used, if applicable)
|
|
|
|
|
type = "fixed",
|
|
|
|
|
fixed = box OR {box1, box2, ...}
|
|
|
|
|
}
|
|
|
|
|
{
|
|
|
|
|
-- A box like the selection box for torches
|
|
|
|
|
-- (wallmounted param2 is used, if applicable)
|
|
|
|
|
type = "wallmounted",
|
|
|
|
|
wall_top = box,
|
|
|
|
|
wall_bottom = box,
|
|
|
|
|
wall_side = box
|
|
|
|
|
}
|
Nodebox: Allow nodeboxes to "connect"
We introduce a new nodebox type "connected", and allow these nodes to
have optional nodeboxes that connect it to other connecting nodeboxes.
This is all done at scenedraw time in the client. The client will
inspect the surrounding nodes and if they are to be connected to,
it will draw the appropriate connecting nodeboxes to make those
connections.
In the node_box definition, we have to specify separate nodeboxes for
each valid connection. This allows us to make nodes that connect only
horizontally (the common case) by providing optional nodeboxes for +x,
-x, +z, -z directions. Or this allows us to make wires that can connect
up and down, by providing nodeboxes that connect it up and down (+y,
-y) as well.
The optional nodeboxes can be arrays. They are named "connect_top,
"connect_bottom", "connect_front", "connect_left", "connect_back" and
"connect_right". Here, "front" means the south facing side of the node
that has facedir = 0.
Additionally, a "fixed" nodebox list present will always be drawn,
so one can make a central post, for instance. This "fixed" nodebox
can be omitted, or it can be an array of nodeboxes.
Collision boxes are also updated in exactly the same fashion, which
allows you to walk over the upper extremities of the individual
node boxes, or stand really close to them. You can also walk up
node noxes that are small in height, all as expected, and unlike the
NDT_FENCELIKE nodes.
I've posted a screenshot demonstrating the flexibility at
http://i.imgur.com/zaJq8jo.png
In the screenshot, all connecting nodes are of this new subtype.
Transparent textures render incorrectly, Which I don't think is
related to this text, as other nodeboxes also have issues with this.
A protocol bump is performed in order to be able to send older clients
a nodeblock that is usable for them. In order to avoid abuse of users
we send older clients a "full-size" node, so that it's impossible for
them to try and walk through a fence or wall that's created in this
fashion. This was tested with a pre-bump client connected against a
server running the new protocol.
These nodes connect to other nodes, and you can select which ones
those are by specifying node names (or group names) in the
connects_to string array:
connects_to = { "group:fence", "default:wood" }
By default, nodes do not connect to anything, allowing you to create
nodes that always have to be paired in order to connect. lua_api.txt
is updated to reflect the extension to the node_box API.
Example lua code needed to generate these nodes can be found here:

A `box` is defined as:
|
|
|
|
|
|
|
|
|
|
{x1, y1, z1, x2, y2, z2}
|
|
|
|
|
|
2012-06-17 16:23:58 +02:00
|
|
|
|
A box of a regular node would look like:
|
2012-06-16 22:42:04 +02:00
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
{-0.5, -0.5, -0.5, 0.5, 0.5, 0.5},
|
|
|
|
|
|
|
|
|
|
`type = "leveled"` is same as `type = "fixed"`, but `y2` will be automatically
|
|
|
|
|
set to level from `param2`.

2014-12-15 20:59:20 +01:00
|
|
|
|
------
|
|
|
|
|
If drawtype `mesh` is used, tiles should hold model materials textures.
|
2015-02-12 17:57:22 +01:00
|
|
|
|
Only static meshes are implemented.

Noise Parameters
|
2014-12-15 20:59:20 +01:00
|
|
|
|
----------------
|
2015-02-22 18:12:55 +01:00
|
|
|
|
Noise Parameters, or commonly called "`NoiseParams`", define the properties of
|
|
|
|
|
perlin noise.
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
|
|
|
|
### `offset`
|
|
|
|
|
Offset that the noise is translated by (i.e. added) after calculation.
|
|
|
|
|
|
|
|
|
|
### `scale`
|
|
|
|
|
Factor that the noise is scaled by (i.e. multiplied) after calculation.
|
|
|
|
|
|
|
|
|
|
### `spread`
|
|
|
|
|
Vector containing values by which each coordinate is divided by before calculation.
|
|
|
|
|
Higher spread values result in larger noise features.
|
|
|
|
|
|
|
|
|
|
A value of `{x=250, y=250, z=250}` is common.
|
|
|
|
|
|
|
|
|
|
### `seed`
|
|
|
|
|
Random seed for the noise. Add the world seed to a seed offset for world-unique noise.
|
|
|
|
|
In the case of `minetest.get_perlin()`, this value has the world seed automatically added.
|
|
|
|
|
|
|
|
|
|
### `octaves`
|
|
|
|
|
Number of times the noise gradient is accumulated into the noise.
|
|
|
|
|
|
|
|
|
|
Increase this number to increase the amount of detail in the resulting noise.
|
|
|
|
|
|
|
|
|
|
A value of `6` is common.
|
|
|
|
|
|
|
|
|
|
### `persistence`
|
|
|
|
|
Factor by which the effect of the noise gradient function changes with each successive octave.
|
|
|
|
|
|
|
|
|
|
Values less than `1` make the details of successive octaves' noise diminish, while values
|
|
|
|
|
greater than `1` make successive octaves stronger.
|
|
|
|
|
|
|
|
|
|
A value of `0.6` is common.
|
|
|
|
|
|
|
|
|
|
### `lacunarity`
|
|
|
|
|
Factor by which the noise feature sizes change with each successive octave.
|
|
|
|
|
|
|
|
|
|
A value of `2.0` is common.
|
|
|
|
|
|
|
|
|
|
### `flags`
|
|
|
|
|
Leave this field unset for no special handling.
|
|
|
|
|
|
|
|
|
|
Currently supported are `defaults`, `eased` and `absvalue`.
|
|
|
|
|
|
|
|
|
|
#### `defaults`
|
|
|
|
|
Specify this if you would like to keep auto-selection of eased/not-eased while specifying
|
|
|
|
|
some other flags.
|
|
|
|
|
|
|
|
|
|
#### `eased`
|
|
|
|
|
Maps noise gradient values onto a quintic S-curve before performing interpolation.
|
|
|
|
|
This results in smooth, rolling noise. Disable this (`noeased`) for sharp-looking noise.
|
|
|
|
|
If no flags are specified (or defaults is), 2D noise is eased and 3D noise is not eased.
|
|
|
|
|
|
|
|
|
|
#### `absvalue`
|
|
|
|
|
Accumulates the absolute value of each noise gradient result.

Ore types
|
2014-12-15 20:59:20 +01:00
|
|
|
|
---------
|
2013-03-24 20:12:29 +01:00
|
|
|
|
These tell in what manner the ore is generated.
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
2013-03-24 20:12:29 +01:00
|
|
|
|
All default ores are of the uniformly-distributed scatter type.
|
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
### `scatter`
|
|
|
|
|
Randomly chooses a location and generates a cluster of ore.
|
|
|
|
|
|
|
|
|
|
If `noise_params` is specified, the ore will be placed if the 3D perlin noise at
|
2015-02-22 18:12:55 +01:00
|
|
|
|
that point is greater than the `noise_threshold`, giving the ability to create
|
|
|
|
|
a non-equal distribution of ore.
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
|
|
|
|
### `sheet`
|
2015-02-22 18:12:55 +01:00
|
|
|
|
Creates a sheet of ore in a blob shape according to the 2D perlin noise
|
2015-09-16 03:28:16 +02:00
|
|
|
|
described by `noise_params` and `noise_threshold`. This is essentially an
|
|
|
|
|
improved version of the so-called "stratus" ore seen in some unofficial mods.
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
2015-09-13 06:09:00 +02:00
|
|
|
|
This sheet consists of vertical columns of uniform randomly distributed height,
|
|
|
|
|
varying between the inclusive range `column_height_min` and `column_height_max`.
|
|
|
|
|
If `column_height_min` is not specified, this parameter defaults to 1.
|
|
|
|
|
If `column_height_max` is not specified, this parameter defaults to `clust_size`
|
|
|
|
|
for reverse compatibility. New code should prefer `column_height_max`.
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
2015-09-13 06:09:00 +02:00
|
|
|
|
The `column_midpoint_factor` parameter controls the position of the column at which
|
|
|
|
|
ore eminates from. If 1, columns grow upward. If 0, columns grow downward. If 0.5,
|
|
|
|
|
columns grow equally starting from each direction. `column_midpoint_factor` is a
|
|
|
|
|
decimal number ranging in value from 0 to 1. If this parameter is not specified,
|
|
|
|
|
the default is 0.5.
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
2015-09-13 06:09:00 +02:00
|
|
|
|
The ore parameters `clust_scarcity` and `clust_num_ores` are ignored for this ore type.
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
2015-09-16 03:28:16 +02:00
|
|
|
|
### `puff`
|
|
|
|
|
Creates a sheet of ore in a cloud-like puff shape.
|
|
|
|
|
|
|
|
|
|
As with the `sheet` ore type, the size and shape of puffs are described by
|
|
|
|
|
`noise_params` and `noise_threshold` and are placed at random vertical positions
|
|
|
|
|
within the currently generated chunk.
|
|
|
|
|
|
|
|
|
|
The vertical top and bottom displacement of each puff are determined by the noise
|
|
|
|
|
parameters `np_puff_top` and `np_puff_bottom`, respectively.
|
|
|
|
|
|
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
### `blob`
|
2015-02-12 17:57:22 +01:00
|
|
|
|
Creates a deformed sphere of ore according to 3d perlin noise described by
|
2014-12-15 20:59:20 +01:00
|
|
|
|
`noise_params`. The maximum size of the blob is `clust_size`, and
|
|
|
|
|
`clust_scarcity` has the same meaning as with the `scatter` type.
|
2015-09-13 06:09:00 +02:00
|
|
|
|
|
2015-09-16 03:28:16 +02:00
|
|
|
|
### `vein`
|
2014-12-15 20:59:20 +01:00
|
|
|
|
Creates veins of ore varying in density by according to the intersection of two
|
|
|
|
|
instances of 3d perlin noise with diffferent seeds, both described by
|
|
|
|
|
`noise_params`. `random_factor` varies the influence random chance has on
|
|
|
|
|
placement of an ore inside the vein, which is `1` by default. Note that
|
2015-12-05 14:00:11 +01:00
|
|
|
|
modifying this parameter may require adjusting `noise_threshold`.
|
2014-12-15 20:59:20 +01:00
|
|
|
|
The parameters `clust_scarcity`, `clust_num_ores`, and `clust_size` are ignored
|
|
|
|
|
by this ore type. This ore type is difficult to control since it is sensitive
|
|
|
|
|
to small changes. The following is a decent set of parameters to work from:
|
|
|
|
|
|
|
|
|
|
noise_params = {
|
|
|
|
|
offset = 0,
|
|
|
|
|
scale = 3,
|
|
|
|
|
spread = {x=200, y=200, z=200},

|
|
seed = 5390,
|
|
|
|
|
octaves = 4,
|
|
|
|
|
persist = 0.5,
|
|
|
|
|
flags = "eased",
|
|
|
|
|
},
|
2015-12-05 14:00:11 +01:00
|
|
|
|
noise_threshold = 1.6
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
2017-06-02 14:15:49 +02:00
|
|
|
|
**WARNING**: Use this ore type *very* sparingly since it is ~200x more
|
2014-12-15 20:59:20 +01:00
|
|
|
|
computationally expensive than any other ore.
|

|
|
|
|
|
|
2017-06-02 14:15:49 +02:00
|
|
|
|
Currently supported flags:
|
2017-06-22 07:50:22 +02:00
|
|
|
|
`puff_cliffs`, `puff_additive_composition`.
|

|
|
|
|
|
2015-09-16 03:28:16 +02:00
|
|
|
|
### `puff_cliffs`
|
|
|
|
|
If set, puff ore generation will not taper down large differences in displacement
|
|
|
|
|
when approaching the edge of a puff. This flag has no effect for ore types other
|
|
|
|
|
than `puff`.
|
|
|
|
|
|
|
|
|
|
### `puff_additive_composition`
|
|
|
|
|
By default, when noise described by `np_puff_top` or `np_puff_bottom` results in a
|
|
|
|
|
negative displacement, the sub-column at that point is not generated. With this
|
|
|
|
|
attribute set, puff ore generation will instead generate the absolute difference in
|
|
|
|
|
noise displacement values. This flag has no effect for ore types other than `puff`.

|
|
|
|
### `simple`
|
2015-02-22 18:12:55 +01:00
|
|
|
|
Creates a 1 times `H` times 1 column of a specified node (or a random node from
|
|
|
|
|
a list, if a decoration list is specified). Can specify a certain node it must
|
|
|
|
|
spawn next to, such as water or lava, for example. Can also generate a
|
|
|
|
|
decoration of random height between a specified lower and upper bound.
|
|
|
|
|
This type of decoration is intended for placement of grass, flowers, cacti,
|
2015-10-21 09:51:59 +02:00
|
|
|
|
papyri, waterlilies and so on.
|
2014-12-15 20:59:20 +01:00
|

|
|
|
|
|
|
### `schematic`
|
2015-02-22 18:12:55 +01:00
|
|
|
|
Copies a box of `MapNodes` from a specified schematic file (or raw description).
|
|
|
|
|
Can specify a probability of a node randomly appearing when placed.
|
|
|
|
|
This decoration type is intended to be used for multi-node sized discrete
|
|
|
|
|
structures, such as trees, cave spikes, rocks, and so on.

Schematic specifier
|
|
|
|
|
--------------------
|
2015-02-22 18:12:55 +01:00
|
|
|
|
A schematic specifier identifies a schematic by either a filename to a
|
|
|
|
|
Minetest Schematic file (`.mts`) or through raw data supplied through Lua,
|
2015-05-09 07:38:20 +02:00
|
|
|
|
in the form of a table. This table specifies the following fields:
|
|
|
|
|
|
|
|
|
|
* The `size` field is a 3D vector containing the dimensions of the provided schematic. (required)
|
|
|
|
|
* The `yslice_prob` field is a table of {ypos, prob} which sets the `ypos`th vertical slice
|
|
|
|
|
of the schematic to have a `prob / 256 * 100` chance of occuring. (default: 255)
|
|
|
|
|
* The `data` field is a flat table of MapNode tables making up the schematic,
|
|
|
|
|
in the order of `[z [y [x]]]`. (required)
|
|
|
|
|
Each MapNode table contains:
|
|
|
|
|
* `name`: the name of the map node to place (required)
|
|
|
|
|
* `prob` (alias `param1`): the probability of this node being placed (default: 255)
|
|
|
|
|
* `param2`: the raw param2 value of the node being placed onto the map (default: 0)
|
|
|
|
|
* `force_place`: boolean representing if the node should forcibly overwrite any
|
|
|
|
|
previous contents (default: false)
|
|
|
|
|
|
|
|
|
|
About probability values:
|
2017-06-02 14:15:49 +02:00
|
|
|
|
|
2015-05-09 07:38:20 +02:00
|
|
|
|
* A probability value of `0` or `1` means that node will never appear (0% chance).
|
|
|
|
|
* A probability value of `254` or `255` means the node will always appear (100% chance).
|
|
|
|
|
* If the probability value `p` is greater than `1`, then there is a
|
|
|
|
|
`(p / 256 * 100)` percent chance that node will appear when the schematic is
|
2015-02-22 18:12:55 +01:00
|
|
|
|
placed on the map.

HUD element types
|
2014-12-15 20:59:20 +01:00
|
|
|
|
-----------------
|
2013-04-14 00:20:22 +02:00
|
|
|
|
The position field is used for all element types.
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
2015-02-22 18:12:55 +01:00
|
|
|
|
To account for differing resolutions, the position coordinates are the percentage
|
|
|
|
|
of the screen, ranging in value from `0` to `1`.
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
2015-02-22 18:12:55 +01:00
|
|
|
|
The name field is not yet used, but should contain a description of what the
|
|
|
|
|
HUD element represents. The direction field is the direction in which something
|
|
|
|
|
is drawn.
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
2015-02-22 18:12:55 +01:00
|
|
|
|
`0` draws from left to right, `1` draws from right to left, `2` draws from
|
|
|
|
|
top to bottom, and `3` draws from bottom to top.
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
|
|
|
|
The `alignment` field specifies how the item will be aligned. It ranges from `-1` to `1`,
|
|
|
|
|
with `0` being the center, `-1` is moved to the left/up, and `1` is to the right/down.
|
|
|
|
|
Fractional values can be used.
|
|
|
|
|
|
|
|
|
|
The `offset` field specifies a pixel offset from the position. Contrary to position,
|
2013-04-23 01:47:59 +02:00
|
|
|
|
the offset is not scaled to screen size. This allows for some precisely-positioned
|
|
|
|
|
items in the HUD.
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
|
|
|
|
**Note**: `offset` _will_ adapt to screen DPI as well as user defined scaling factor!
|
|
|
|
|
|
2013-04-14 00:20:22 +02:00

|
|
|
|
2015-02-22 18:12:55 +01:00
|
|
|

**Note**: Future revisions to the HUD API may be incompatible; the HUD API is still
|
|
|
|
|
in the experimental stages.

|
|
|
|
|
Only the X coordinate scale is used (positive values).
|
|
|
|
|
Negative values represent that percentage of the screen it
|
|
|
|
|
should take; e.g. `x=-100` means 100% (width).
|
|
|
|
|
* `text`: The name of the texture that is displayed.

|
|
|
|
|
* `scale`: Defines the bounding rectangle of the text.
|
|
|
|
|
A value such as `{x=100, y=100}` should work.
|
|
|
|
|
* `text`: The text to be displayed in the HUD element.
|
|
|
|
|
* `number`: An integer containing the RGB value of the color used to draw the text.

|
|
|
|
|
|
|
* `text`: The name of the texture that is used.
|
|
|
|
|
* `number`: The number of half-textures that are displayed.
|

|
|
|
|
|
* `offset`: offset in pixels from position.
|
|
|
|
|

|
|
|
|
|
### `inventory`
|
|
|
|
|
* `text`: The name of the inventory list to be displayed.

Flag Specifier Format
|
2014-12-15 20:59:20 +01:00
|
|
|
|
---------------------
|
2015-02-22 18:12:55 +01:00
|
|
|
|
Flags using the standardized flag specifier format can be specified in either of
|
|
|
|
|
two ways, by string or table.
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
2015-02-22 18:12:55 +01:00
|
|
|
|
The string format is a comma-delimited set of flag names; whitespace and
|
|
|
|
|
unrecognized flag fields are ignored. Specifying a flag in the string sets the
|
|
|
|
|
flag, and specifying a flag prefixed by the string `"no"` explicitly
|
2014-02-09 18:38:50 +01:00
|
|
|
|
clears the flag from whatever the default may be.
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
2015-02-22 18:12:55 +01:00
|
|
|
|
In addition to the standard string flag format, the schematic flags field can
|
|
|
|
|
also be a table of flag names to boolean values representing whether or not the
|
|
|
|
|
flag is set. Additionally, if a field with the flag name prefixed with `"no"`
|
|
|
|
|
is present, mapped to a boolean of any value, the specified flag is unset.
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
|
|
|
|
E.g. A flag field of value
|
|
|
|
|
|
|
|
|
|
{place_center_x = true, place_center_y=false, place_center_z=true}
|
2014-02-09 18:38:50 +01:00
|
|
|
|
|
|
|
|
|
is equivalent to
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
|
|
|
|
{place_center_x = true, noplace_center_y=true, place_center_z=true}
|
|
|
|
|
|
2014-02-09 18:38:50 +01:00
|
|
|
|
which is equivalent to
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
|
|
|
|
"place_center_x, noplace_center_y, place_center_z"
|
|
|
|
|
|
2014-02-09 18:38:50 +01:00
|
|
|
|
or even
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
|
|
|
|
"place_center_x, place_center_z"
|
|
|
|
|
|
2014-02-09 18:38:50 +01:00
|
|
|
|
since, by default, no schematic attributes are set.

### Item types
|
|
|
|
|
There are three kinds of items: nodes, tools and craftitems.
|
|
|
|
|
|
|
|
|
|
* Node (`register_node`): A node from the world.
|
|
|
|
|
* Tool (`register_tool`): A tool/weapon that can dig and damage
|
|
|
|
|
things according to `tool_capabilities`.
|
|
|
|
|
* Craftitem (`register_craftitem`): A miscellaneous item.
|
|
|
|
|
|
2017-06-02 14:15:49 +02:00
|
|
|
|
### Amount and wear
|
|
|
|
|
All item stacks have an amount between 0 to 65535. It is 1 by
|
|
|
|
|
default. Tool item stacks can not have an amount greater than 1.
|
|
|
|
|
|
|
|
|
|
Tools use a wear (=damage) value ranging from 0 to 65535. The
|
|
|
|
|
value 0 is the default and used is for unworn tools. The values
|
|
|
|
|
1 to 65535 are used for worn tools, where a higher value stands for
|
|
|
|
|
a higher wear. Non-tools always have a wear value of 0.
|
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
### Item formats
|
|
|
|
|
Items and item stacks can exist in three formats: Serializes, table format
|
|
|
|
|
and `ItemStack`.
|
|
|
|
|
|
|
|
|
|
#### Serialized
|
2017-06-02 14:15:49 +02:00
|
|
|
|
This is called "stackstring" or "itemstring". It is a simple string with
|
|
|
|
|
1-3 components: the full item identifier, an optional amount and an optional
|
|
|
|
|
wear value. Syntax:
|
|
|
|
|
|
|
|
|
|
<identifier> [<amount>[ <wear>]]
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
2017-06-02 14:15:49 +02:00
|
|
|
|
Examples:
|
|
|
|
|
|
|
|
|
|
* `'default:apple'`: 1 apple
|
|
|
|
|
* `'default:dirt 5'`: 5 dirt
|
|
|
|
|
* `'default:pick_stone'`: a new stone pickaxe
|
|
|
|
|
* `'default:pick_wood 1 21323'`: a wooden pickaxe, ca. 1/3 worn out
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
|
|
|
|
#### Table format
|
|
|
|
|
Examples:
|
|
|
|
|
|
|
|
|
|
5 dirt nodes:
|
|
|
|
|
|
|
|
|
|
{name="default:dirt", count=5, wear=0, metadata=""}
|
|
|
|
|
|
|
|
|
|
A wooden pick about 1/3 worn out:
|
|
|
|
|
|
|
|
|
|
{name="default:pick_wood", count=1, wear=21323, metadata=""}
|
|
|
|
|
|
|
|
|
|
An apple:
|
|
|
|
|
|
|
|
|
|
{name="default:apple", count=1, wear=0, metadata=""}
|
|
|
|
|
|
|
|
|
|
#### `ItemStack`
|
|
|
|
|
A native C++ format with many helper methods. Useful for converting
|
|
|
|
|
between formats. See the Class reference section for details.
|
2012-03-22 10:41:40 +01:00
|
|
|
|
|
2012-04-09 11:36:25 +02:00
|
|
|
|
When an item must be passed to a function, it can usually be in any of
|
|
|
|
|
these formats.

Groups
|
2014-12-15 20:59:20 +01:00
|
|
|
|
------
|
2012-03-22 10:41:40 +01:00
|
|
|
|
In a number of places, there is a group table. Groups define the
|
|
|
|
|
properties of a thing (item, node, armor of entity, capabilities of
|
|
|
|
|
tool) in such a way that the engine and other mods can can interact with
|
|
|
|
|
the thing without actually knowing what the thing is.
|
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
### Usage
|
|
|
|
|
Groups are stored in a table, having the group names with keys and the
|
|
|
|
|
group ratings as values. For example:
|
|
|
|
|
|
2012-03-22 10:41:40 +01:00
|
|
|
|
groups = {crumbly=3, soil=1}
|
2014-12-15 20:59:20 +01:00
|
|
|
|
-- ^ Default dirt
|
|
|
|
|
|
2012-03-22 10:41:40 +01:00
|
|
|
|
groups = {crumbly=2, soil=1, level=2, outerspace=1}
|
2014-12-15 20:59:20 +01:00
|
|
|
|
-- ^ A more special dirt-kind of thing
|
|
|
|
|
|
|
|
|
|
Groups always have a rating associated with them. If there is no
|
|
|
|
|
useful meaning for a rating for an enabled group, it shall be `1`.
|
|
|
|
|
|
|
|
|
|
When not defined, the rating of a group defaults to `0`. Thus when you
|
|
|
|
|
read groups, you must interpret `nil` and `0` as the same value, `0`.
|
2012-03-22 10:41:40 +01:00
|
|
|
|
|
2012-04-09 11:36:25 +02:00
|
|
|
|
You can read the rating of a group for an item or a node by using
|
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
minetest.get_item_group(itemname, groupname)
|
|
|
|
|
|
|
|
|
|
### Groups of items
|
2014-07-05 12:19:55 +02:00
|
|
|
|
Groups of items can define what kind of an item it is (e.g. wool).
|
2012-03-22 10:41:40 +01:00
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
### Groups of nodes
|
2012-03-29 12:35:20 +02:00
|
|
|
|
In addition to the general item things, groups are used to define whether
|
|
|
|
|
a node is destroyable and how long it takes to destroy by a tool.
|
2012-03-22 10:41:40 +01:00
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
### Groups of entities
|
2012-03-22 10:41:40 +01:00
|
|
|
|
For entities, groups are, as of now, used only for calculating damage.
|
2013-03-28 21:40:44 +01:00
|
|
|
|
The rating is the percentage of damage caused by tools with this damage group.
|
|
|
|
|
See "Entity damage mechanism".
|
2012-03-22 10:41:40 +01:00
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
object.get_armor_groups() --> a group-rating table (e.g. {fleshy=100})
|
|
|
|
|
object.set_armor_groups({fleshy=30, cracky=80})
|
2012-03-22 10:41:40 +01:00
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
### Groups of tools
|
2012-03-22 10:41:40 +01:00
|
|
|
|
Groups in tools define which groups of nodes and entities they are
|
|
|
|
|
effective towards.
|
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
### Groups in crafting recipes
|
|
|
|
|
An example: Make meat soup from any meat, any water and any bowl:
|
|
|
|
|
|
|
|
|
|
{
|
|
|
|
|
output = 'food:meat_soup_raw',
|
|
|
|
|
recipe = {
|
|
|
|
|
{'group:meat'},
|
|
|
|
|
{'group:water'},
|
|
|
|
|
{'group:bowl'},
|
|
|
|
|
},
|
|
|
|
|
-- preserve = {'group:bowl'}, -- Not implemented yet (TODO)
|
|
|
|
|
}
|
|
|
|
|
|
|
|
|
|
Another example: Make red wool from white wool and red dye:
|
|
|
|
|
|
|
|
|
|
{
|
|
|
|
|
type = 'shapeless',
|
|
|
|
|
output = 'wool:red',
|
|
|
|
|
recipe = {'wool:white', 'group:dye,basecolor_red'},
|
|
|
|
|
}
|
|
|
|
|
|
|
|
|
|
### Special groups
|
|
|
|
|
* `immortal`: Disables the group damage system for an entity
|
2017-06-02 14:15:49 +02:00
|
|
|
|
* `punch_operable`: For entities; disables the regular damage mechanism for
|
|
|
|
|
players punching it by hand or a non-tool item, so that it can do something
|
|
|
|
|
else than take damage.
|
2014-12-15 20:59:20 +01:00
|
|
|
|
* `level`: Can be used to give an additional sense of progression in the game.
|
|
|
|
|
* A larger level will cause e.g. a weapon of a lower level make much less
|
|
|
|
|
damage, and get worn out much faster, or not be able to get drops
|
|
|
|
|
from destroyed nodes.
|
|
|
|
|
* `0` is something that is directly accessible at the start of gameplay
|
|
|
|
|
* There is no upper limit
|
2017-04-28 20:12:28 +02:00
|
|
|
|
* `dig_immediate`: (player can always pick up node without reducing tool wear)
|
|
|
|
|
* `2`: the node always gets the digging time 0.5 seconds (rail, sign)
|
|
|
|
|
* `3`: the node always gets the digging time 0 seconds (torch)
|
2014-12-15 20:59:20 +01:00
|
|
|
|
* `disable_jump`: Player (and possibly other things) cannot jump from node
|
|
|
|
|
* `fall_damage_add_percent`: damage speed = `speed * (1 + value/100)`
|
|
|
|
|
* `bouncy`: value is bounce speed in percent
|
|
|
|
|
* `falling_node`: if there is no walkable block under the node it will fall
|
|
|
|
|
* `attached_node`: if the node under it is not a walkable block the node will be
|
|
|
|
|
dropped as an item. If the node is wallmounted the wallmounted direction is
|
|
|
|
|
checked.
|
|
|
|
|
* `soil`: saplings will grow on nodes in this group
|
2015-02-22 15:12:05 +01:00
|
|
|
|
* `connect_to_raillike`: makes nodes of raillike drawtype with same group value
|
|
|
|
|
connect to each other
|
2017-08-11 21:16:09 +02:00
|
|
|
|
* `slippery`: Players and items will slide on the node.
|
|
|
|
|
Only use `slippery = 3` for now to ensure forwards compatibility.
|
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
|
|
|
|
### Known damage and digging time defining groups
|
|
|
|
|
* `crumbly`: dirt, sand
|
|
|
|
|
* `cracky`: tough but crackable stuff like stone.
|
|
|
|
|
* `snappy`: something that can be cut using fine tools; e.g. leaves, small
|
|
|
|
|
plants, wire, sheets of metal
|
|
|
|
|
* `choppy`: something that can be cut using force; e.g. trees, wooden planks
|
|
|
|
|
* `fleshy`: Living things like animals and the player. This could imply
|
|
|
|
|
some blood effects when hitting.
|
|
|
|
|
* `explody`: Especially prone to explosions
|
|
|
|
|
* `oddly_breakable_by_hand`:
|
2012-03-22 10:41:40 +01:00
|
|
|
|
Can be added to nodes that shouldn't logically be breakable by the
|
2014-12-15 20:59:20 +01:00
|
|
|
|
hand but are. Somewhat similar to `dig_immediate`, but times are more
|
|
|
|
|
like `{[1]=3.50,[2]=2.00,[3]=0.70}` and this does not override the
|
2012-04-09 11:36:25 +02:00
|
|
|
|
speed of a tool if the tool can dig at a faster speed than this
|
2012-03-22 10:41:40 +01:00
|
|
|
|
suggests for the hand.
|

### Examples of custom groups
|
|
|
|
|
Item groups are often used for defining, well, _groups of items_.
|
2017-06-02 14:15:49 +02:00
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
* `meat`: any meat-kind of a thing (rating might define the size or healing
|
|
|
|
|
ability or be irrelevant -- it is not defined as of yet)
|
|
|
|
|
* `eatable`: anything that can be eaten. Rating might define HP gain in half
|
2012-03-22 10:41:40 +01:00
|
|
|
|
hearts.
|
2014-12-15 20:59:20 +01:00
|
|
|
|
* `flammable`: can be set on fire. Rating might define the intensity of the
|
2014-07-05 12:19:55 +02:00
|
|
|
|
fire, affecting e.g. the speed of the spreading of an open fire.
|

### Digging time calculation specifics
|
|
|
|
|
Groups such as `crumbly`, `cracky` and `snappy` are used for this
|
|
|
|
|
purpose. Rating is `1`, `2` or `3`. A higher rating for such a group implies
|
2012-03-22 10:41:40 +01:00
|
|
|
|
faster digging time.
|
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
The `level` group is used to limit the toughness of nodes a tool can dig
|
2012-03-29 12:35:20 +02:00
|
|
|
|
and to scale the digging times / damage to a greater extent.
|
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
**Please do understand this**, otherwise you cannot use the system to it's
|
|
|
|
|
full potential.
|
2012-03-22 10:41:40 +01:00
|
|
|
|
|
|
|
|
|
Tools define their properties by a list of parameters for groups. They
|
|
|
|
|
cannot dig other groups; thus it is important to use a standard bunch of
|
|
|
|
|
groups to enable interaction with tools.
|
|

|
#### Tools definition
|
|
|
|
|
Tools define:
|
|
|
|
|
|
|
|
|
|
* Full punch interval
|
|
|
|
|
* Maximum drop level
|
|
|
|
|
* For an arbitrary list of groups:
|
2012-03-29 12:35:20 +02:00
|
|
|
|
* Uses (until the tool breaks)
|
2014-12-15 20:59:20 +01:00
|
|
|
|
* Maximum level (usually `0`, `1`, `2` or `3`)
|
|
|
|
|
* Digging times
|
|
|
|
|
* Damage groups
|
2012-03-29 12:35:20 +02:00
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
#### Full punch interval
|
2012-03-29 12:35:20 +02:00
|
|
|
|
When used as a weapon, the tool will do full damage if this time is spent
|
2014-07-05 12:19:55 +02:00
|
|
|
|
between punches. If e.g. half the time is spent, the tool will do half
|
2012-03-29 12:35:20 +02:00
|
|
|
|
damage.
|
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
#### Maximum drop level
|
2012-03-29 12:35:20 +02:00
|
|
|
|
Suggests the maximum level of node, when dug with the tool, that will drop
|
2014-07-05 12:19:55 +02:00
|
|
|
|
it's useful item. (e.g. iron ore to drop a lump of iron).
|
2012-03-29 12:35:20 +02:00
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
This is not automated; it is the responsibility of the node definition
|
|
|
|
|
to implement this.
|
|
|
|
|
|
|
|
|
|
#### Uses
|
2012-03-29 12:35:20 +02:00
|
|
|
|
Determines how many uses the tool has when it is used for digging a node,
|
|
|
|
|
of this group, of the maximum level. For lower leveled nodes, the use count
|
2014-12-15 20:59:20 +01:00
|
|
|
|
is multiplied by `3^leveldiff`.
|
|
|
|
|
|
|
|
|
|
* `uses=10, leveldiff=0`: actual uses: 10
|
|
|
|
|
* `uses=10, leveldiff=1`: actual uses: 30
|
|
|
|
|
* `uses=10, leveldiff=2`: actual uses: 90
|
2012-03-29 12:35:20 +02:00
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
#### Maximum level
|
2012-03-29 12:35:20 +02:00
|
|
|
|
Tells what is the maximum level of a node of this group that the tool will
|
|
|
|
|
be able to dig.
|
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
#### Digging times
|
2012-03-29 12:35:20 +02:00
|
|
|
|
List of digging times for different ratings of the group, for nodes of the
|
|
|
|
|
maximum level.
|
2013-03-28 21:40:44 +01:00
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
For example, as a Lua table, `times={2=2.00, 3=0.70}`. This would
|
|
|
|
|
result in the tool to be able to dig nodes that have a rating of `2` or `3`
|
|
|
|
|
for this group, and unable to dig the rating `1`, which is the toughest.
|
|
|
|
|
Unless there is a matching group that enables digging otherwise.
|
|
|
|
|
|
2017-04-28 20:12:28 +02:00
|
|
|
|
If the result digging time is 0, a delay of 0.15 seconds is added between
|
|
|
|
|
digging nodes; If the player releases LMB after digging, this delay is set to 0,
|
|
|
|
|
i.e. players can more quickly click the nodes away instead of holding LMB.
|
|
|
|
|
|

|
|
|
|
#### Damage groups
|
2013-03-28 21:40:44 +01:00
|
|
|
|
List of damage for groups of entities. See "Entity damage mechanism".

|
#### Example definition of the capabilities of a tool
|
|
|
|
|
|
|
|
|
|
tool_capabilities = {
|
|
|
|
|
full_punch_interval=1.5,
|
|
|
|
|
max_drop_level=1,
|
|
|
|
|
groupcaps={
|
|
|
|
|
crumbly={maxlevel=2, uses=20, times={[1]=1.60, [2]=1.20, [3]=0.80}}
|
|
|
|
|
}
|
|
|
|
|
damage_groups = {fleshy=2},
|
2013-03-24 20:39:15 +01:00
|
|
|
|
}
|
2012-03-22 10:41:40 +01:00
|
|
|
|
|
2014-08-22 19:34:16 +02:00
|
|
|
|
This makes the tool be able to dig nodes that fulfil both of these:
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
|
|
|
|
* Have the `crumbly` group
|
|
|
|
|
* Have a `level` group less or equal to `2`

**Notes**:
|
|
|
|
|
|
|
|
|
|
* At `crumbly==0`, the node is not diggable.
|
|
|
|
|
* At `crumbly==3`, the level difference digging time divider kicks in and makes
|
2012-03-29 12:35:20 +02:00
|
|
|
|
easy nodes to be quickly breakable.
|
2014-12-15 20:59:20 +01:00
|
|
|
|
* At `level > 2`, the node is not diggable, because it's `level > maxlevel`

Damage calculation:
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
|
|
|
|
damage = 0
|
|
|
|
|
foreach group in cap.damage_groups:
|
2015-02-22 18:12:55 +01:00
|
|
|
|
damage += cap.damage_groups[group] * limit(actual_interval /
|
|
|
|
|
cap.full_punch_interval, 0.0, 1.0)
|
2014-12-15 20:59:20 +01:00
|
|
|
|
* (object.armor_groups[group] / 100.0)
|
|
|
|
|
-- Where object.armor_groups[group] is 0 for inexistent values
|
|
|
|
|
return damage
|
2012-03-29 12:35:20 +02:00
|
|
|
|
|
2012-03-22 10:41:40 +01:00
|
|
|
|
Client predicts damage based on damage groups. Because of this, it is able to
|
|
|
|
|
give an immediate response when an entity is damaged or dies; the response is
|
2014-07-05 12:19:55 +02:00
|
|
|
|
pre-defined somehow (e.g. by defining a sprite animation) (not implemented;
|
2015-02-12 17:57:22 +01:00
|
|
|
|
TODO).
|
2014-12-15 20:59:20 +01:00
|
|
|
|
Currently a smoke puff will appear when an entity dies.
|
2012-03-22 10:41:40 +01:00
|
|
|
|

2014-12-15 20:59:20 +01:00
|
|
|
|
The group `immortal` completely disables normal damage.
|
2012-03-22 10:41:40 +01:00
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
Entities can define a special armor group, which is `punch_operable`. This
|
2012-04-09 11:36:25 +02:00
|
|
|
|
group disables the regular damage mechanism for players punching it by hand or
|
|
|
|
|
a non-tool item, so that it can do something else than take damage.
|
2012-03-22 10:41:40 +01:00
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
On the Lua side, every punch calls:
|
|
|
|
|
|
2017-01-21 15:58:07 +01:00
|
|
|
|
entity:on_punch(puncher, time_from_last_punch, tool_capabilities, direction, damage)
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
2015-02-22 18:12:55 +01:00
|
|
|
|
This should never be called directly, because damage is usually not handled by
|
|
|
|
|
the entity itself.
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
|
|
|
|
* `puncher` is the object performing the punch. Can be `nil`. Should never be
|
|
|
|
|
accessed unless absolutely required, to encourage interoperability.
|
|
|
|
|
* `time_from_last_punch` is time from last punch (by `puncher`) or `nil`.
|
|
|
|
|
* `tool_capabilities` can be `nil`.
|
|
|
|
|
* `direction` is a unit vector, pointing from the source of the punch to
|
|
|
|
|
the punched object.
|
2017-01-21 15:58:07 +01:00
|
|
|
|
* `damage` damage that will be done to entity
|
2017-01-31 20:49:01 +01:00
|
|
|
|
Return value of this function will determin if damage is done by this function
|
2017-01-21 15:58:07 +01:00
|
|
|
|
(retval true) or shall be done by engine (retval false)
|
2014-12-15 20:59:20 +01:00
|
|
|
|
|
|
|
|
|
To punch an entity/object in Lua, call:
|
|
|
|
|
|
|
|
|
|
object:punch(puncher, time_from_last_punch, tool_capabilities, direction)
|
|
|
|
|
|
|
|
|
|
* Return value is tool wear.
|
|
|
|
|
* Parameters are equal to the above callback.
|
|
|
|
|
* If `direction` equals `nil` and `puncher` does not equal `nil`,
|
|
|
|
|
`direction` will be automatically filled in based on the location of `puncher`.

Node Metadata
|
|
|
|
|
-------------
|
|
|
|
|
The instance of a node in the world normally only contains the three values
|
|
|
|
|
mentioned in "Nodes". However, it is possible to insert extra data into a
|
2017-01-31 20:49:01 +01:00
|
|
|
|
node. It is called "node metadata"; See `NodeMetaRef`.
|
2012-06-02 10:01:28 +02:00
|
|
|
|
|
2017-01-31 20:49:01 +01:00
|
|
|
|
Node metadata contains two things:
|
2015-12-07 07:26:12 +01:00
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
* A key-value store
|
|
|
|
|
* An inventory
|
2012-06-02 10:01:28 +02:00
|
|
|
|
|
|
|
|
|
Some of the values in the key-value store are handled specially:
|
2015-12-07 07:26:12 +01:00
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
* `formspec`: Defines a right-click inventory menu. See "Formspec".
|
|
|
|
|
* `infotext`: Text shown on the screen when the node is pointed at
|
2012-06-02 10:01:28 +02:00
|
|
|
|
|
|
|
|
|
Example stuff:

Item Metadata
|
|
|
|
|
-------------
|
|
|
|
|
Item stacks can store metadata too. See `ItemStackMetaRef`.
|
|
|
|
|
|
|
|
|
|
Item metadata only contains a key-value store.
|
|
|
|
|
|
2017-02-03 23:28:09 +01:00
|
|
|
|
Some of the values in the key-value store are handled specially:
|
|
|
|
|
|
2017-06-02 14:15:49 +02:00
|
|
|
|
* `description`: Set the item stack's description. Defaults to `idef.description`
|
2017-03-10 18:25:58 +01:00
|
|
|
|
* `color`: A `ColorString`, which sets the stack's color.
|
|
|
|
|
* `palette_index`: If the item has a palette, this is used to get the
|
|
|
|
|
current color from the palette.

Formspec
|
|
|
|
|
--------
|
|
|
|
|
Formspec defines a menu. Currently not much else than inventories are
|
|
|
|
|
supported. It is a string, with a somewhat strange format.
|
|
|
|
|
|
|
|
|
|
Spaces and newlines can be inserted between the blocks, as is used in the
|
|
|
|
|
examples.

`ColorString`
|
|
|
|
|
-------------
|
|
|
|
|
`#RGB` defines a color in hexadecimal format.
|
2012-06-02 10:01:28 +02:00
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
`#RGBA` defines a color in hexadecimal format and alpha channel.
|
|
|
|
|
|
|
|
|
|
`#RRGGBB` defines a color in hexadecimal format.
|
|
|
|
|
|
|
|
|
|
`#RRGGBBAA` defines a color in hexadecimal format and alpha channel.
|
|
|
|
|
|
|
|
|
|
Named colors are also supported and are equivalent to
|
|
|
|
|
[CSS Color Module Level 4](http://dev.w3.org/csswg/css-color/#named-colors).
|
|
|
|
|
To specify the value of the alpha channel, append `#AA` to the end of the color name
|
|
|
|
|
(e.g. `colorname#08`). For named colors the hexadecimal string representing the alpha
|
|
|
|
|
value must (always) be two hexadecimal digits.

`ColorSpec`
|
|
|
|
|
-----------
|
|
|
|
|
A ColorSpec specifies a 32-bit color. It can be written in either:
|
|
|
|
|
table form, each element ranging from 0..255 (a, if absent, defaults to 255):
|
|
|
|
|
`colorspec = {a=255, r=0, g=255, b=0}`
|
|
|
|
|
numerical form, the raw integer value of an ARGB8 quad:
|
|
|
|
|
`colorspec = 0xFF00FF00`
|
|
|
|
|
or string form, a ColorString (defined above):
|
|
|
|
|
`colorspec = "green"`

Escape sequences
|
|
|
|
|
----------------
|
|
|
|
|
Most text can contain escape sequences, that can for example color the text.

|
|
There are a few exceptions: tab headers, dropdowns and vertical labels can't.
|
|
|
|
|
The following functions provide escape sequences:

|
|
|
|
table does not represent the capabilities of the engine, nor is it
|
|
|
|
|
reliable or verifyable. Compatible forks will have a different name and
|
|
|
|
|
version entirely. To check for the presence of engine features, test
|
|
|
|
|
whether the functions exported by the wanted features exist. For example:
|
2017-05-12 11:27:58 +02:00
|
|
|
|
`if minetest.nodeupdate then ... end`.

Add minetest.check_password_entry callback
Gives a convenient way to check a player's password.
This entirely bypasses the SRP protocol, so should be used
with great care.
This function is not intended to be used
in-game, but solely by external protocols, where no
authentication of the minetest engine is provided, and
also only for protocols, in which the user already gives the
server the plaintext password.
Examples for good use are the classical http form, or irc,
an example for a bad use is a password change dialog inside
formspec.
Users should be aware that they lose the advantages of the SRP
protocol if they enter their passwords for servers outside the
normal entry box, like in in-game formspec menus,
or through irc /msg s,
This patch also fixes an auth.h mistake which has mixed up the
order of params inside the decode_srp_verifier_and_salt function.

|
|
|
* `minetest.check_password_entry(name, entry, password)`
|
|
|
|
|
* Returns true if the "db entry" for a player with name matches given
|
|
|
|
|
* password, false otherwise.
|
|
|
|
|
* The "db entry" is the usually player-individual value that is derived
|
|
|
|
|
* from the player's chosen password and stored on the server in order to allow
|
|
|
|
|
* authentication whenever the player desires to log in.
|
|
|
|
|
* Only use this function for making it possible to log in via the password from
|
|
|
|
|
* via protocols like IRC, other uses for inside the game are frowned upon.
|
2014-12-15 20:59:20 +01:00

|
|
|
|
* Convert a name-password pair to a password hash that Minetest can use.
|
|
|
|
|
* The returned value alone is not a good basis for password checks based
|
|
|
|
|
* on comparing the password hash in the database with the password hash
|
|
|
|
|
* from the function, with an externally provided password, as the hash
|
|
|
|
|
* in the db might use the new SRP verifier format.
|
2017-06-02 14:15:49 +02:00
|

the first parameter, and with either a table or a list of strings, like
this:
minetest.check_player_privs(player_name, { shout = true, fly = true })
minetest.check_player_privs(player_name, "shout", "fly")
minetest.check_player_privs(player, { shout = true, fly = true })
minetest.check_player_privs(player, "shout", "fly")
2015-09-03 21:28:38 +02:00
|
|
|
|
* `minetest.check_player_privs(player_or_name, ...)`: returns `bool, missing_privs`

* Example: `parse_json("[10, {\"a\":false}]")`, returns `{10, {a = false}}`
|
|
|
|
|
* `minetest.write_json(data[, styled])`: returns a string or `nil` and an error message
|
|
|
|
|
* Convert a Lua table into a JSON string
|
|
|
|
|
* styled: Outputs in a human-readable format if this is set, defaults to false
|
2017-04-08 10:42:59 +02:00
|
|
|
|
* Unserializable things like functions and userdata will cause an error.
|
2014-12-15 20:59:20 +01:00
|
|
|
|
* **Warning**: JSON is more strict than the Lua table format.
|
|
|
|
|
1. You can only use strings and positive integers of at least one as keys.
|
|
|
|
|
2. You can not mix string and integer keys.
|
|
|
|
|
This is due to the fact that JSON has two distinct array and object values.
|
|
|
|
|
* Example: `write_json({10, {a = false}})`, returns `"[10, {\"a\": false}]"`
|
|
|
|
|
* `minetest.serialize(table)`: returns a string
|
|
|
|
|
* Convert a table containing tables, strings, numbers, booleans and `nil`s
|
|
|
|
|
into string form readable by `minetest.deserialize`
|
|
|
|
|
* Example: `serialize({foo='bar'})`, returns `'return { ["foo"] = "bar" }'`
|
|
|
|
|
* `minetest.deserialize(string)`: returns a table
|
|
|
|
|
* Convert a string returned by `minetest.deserialize` into a table
|
|
|
|
|
* `string` is loaded in an empty sandbox environment.
|
|
|
|
|
* Will load functions, but they cannot access the global environment.
|
|
|
|
|
* Example: `deserialize('return { ["foo"] = "bar" }')`, returns `{foo='bar'}`
|
|
|
|
|
* Example: `deserialize('print("foo")')`, returns `nil` (function call fails)
|
|
|
|
|
* `error:[string "print("foo")"]:1: attempt to call global 'print' (a nil value)`
|
|
|
|
|
* `minetest.compress(data, method, ...)`: returns `compressed_data`
|
|
|
|
|
* Compress a string of data.
|
|
|
|
|
* `method` is a string identifying the compression method to be used.
|
|
|
|
|
* Supported compression methods:
|
|
|
|
|
* Deflate (zlib): `"deflate"`
|
|
|
|
|
* `...` indicates method-specific arguments. Currently defined arguments are:
|
|
|
|
|
* Deflate: `level` - Compression level, `0`-`9` or `nil`.
|
|
|
|
|
* `minetest.decompress(compressed_data, method, ...)`: returns data
|
|
|
|
|
* Decompress a string of data (using ZLib).
|
|
|
|
|
* See documentation on `minetest.compress()` for supported compression methods.
|
|
|
|
|
* currently supported.
|
|
|
|
|
* `...` indicates method-specific arguments. Currently, no methods use this.
|

|
|
|
|
* `minetest.rgba(red, green, blue[, alpha])`: returns a string
|
|
|
|
|
* Each argument is a 8 Bit unsigned integer
|
|
|
|
|
* Returns the ColorString from rgb or rgba values
|
|
|
|
|
* Example: `minetest.rgba(10, 20, 30, 40)`, returns `"#0A141E28"`

|
* `minetest.is_protected(pos, name)`: returns boolean
|
2015-08-02 18:23:22 +02:00
|
|
|
|
* Returns true, if player `name` shouldn't be abled to dig at `pos` or do other
|
|
|
|
|
actions, defineable by mods, due to some mod-defined ownership-like concept.
|
|
|
|
|
Returns false or nil, if the player is allowed to do such actions.
|
2014-12-15 20:59:20 +01:00
|
|
|
|
* This function should be overridden by protection mods and should be used to
|
|
|
|
|
check if a player can interact at a position.
|
|
|
|
|
* This function should call the old version of itself if the position is not
|
|
|
|
|
protected by the mod.
|
|
|
|
|
* Example:
|
|
|
|
|
|
|
|
|
|
local old_is_protected = minetest.is_protected
|
|
|
|
|
function minetest.is_protected(pos, name)

end
|
|
|
|
|
* `minetest.record_protection_violation(pos, name)`
|
|
|
|
|
* This function calls functions registered with
|
|
|
|
|
`minetest.register_on_protection_violation`.
|
|
|
|
|
* `minetest.rotate_and_place(itemstack, placer, pointed_thing, infinitestacks, orient_flags)`
|
|
|
|
|
* Attempt to predict the desired orientation of the facedir-capable node
|
|
|
|
|
defined by `itemstack`, and place it accordingly (on-wall, on the floor, or
|
|
|
|
|
hanging from the ceiling). Stacks are handled normally if the `infinitestacks`
|
|
|
|
|
field is false or omitted (else, the itemstack is not changed). `orient_flags`
|
|
|
|
|
is an optional table containing extra tweaks to the placement code:
|
|
|
|
|
* `invert_wall`: if `true`, place wall-orientation on the ground and ground-
|
|
|
|
|
orientation on the wall.
|
|
|
|
|
* `force_wall` : if `true`, always place the node in wall orientation.
|
|
|
|
|
* `force_ceiling`: if `true`, always place on the ceiling.
|
|
|
|
|
* `force_floor`: if `true`, always place the node on the floor.
|
|
|
|
|
* `force_facedir`: if `true`, forcefully reset the facedir to north when placing on
|
|
|
|
|
the floor or ceiling
|
|
|
|
|
* The first four options are mutually-exclusive; the last in the list takes
|
|
|
|
|
precedence over the first.
|
|
|
|

status will only be remembered if an associated key-value pair exists, meaning
|
2017-06-02 14:15:49 +02:00

returns the items that were actually removed (as an `ItemStack`) -- note that
|
|
|
|
|
any item metadata is ignored, so attempting to remove a specific unique
|
|
|
|
|
item this way will likely remove the wrong one -- to do that use `set_stack`
|
|
|
|
|
with an empty `ItemStack`
|
|
|
|
|
* `get_location()`: returns a location compatible to `minetest.get_inventory(location)`
|
|
|
|
|
* returns `{type="undefined"}` in case location is not known

### `AreaStore`
|
|
|
|
|
A fast access data structure to store areas, and find areas near a given position or area.
|
|
|
|
|
Every area has a `data` string attribute to store additional information.
|
|
|
|
|
You can create an empty `AreaStore` by calling `AreaStore()`, or `AreaStore(type_name)`.
|
2016-06-07 04:23:23 +02:00
|
|
|
|
If you chose the parameter-less constructor, a fast implementation will be automatically
|
|
|
|
|
chosen for you.

|
|
|
|
* `get_area(id, include_borders, include_data)`: returns the area with the id `id`.
|
|
|
|
|
(optional) Boolean values `include_borders` and `include_data` control what's copied.
|
2016-09-09 17:47:13 +02:00
|
|
|
|
Returns nil if specified area id does not exist.
|
2016-06-07 04:23:23 +02:00
|
|
|
|
* `get_areas_for_pos(pos, include_borders, include_data)`: returns all areas that contain
|
|
|
|
|
the position `pos`. (optional) Boolean values `include_borders` and `include_data` control
|
|
|
|
|
what's copied.
|
|
|
|
|
* `get_areas_in_area(edge1, edge2, accept_overlap, include_borders, include_data)`:
|
|
|
|
|
returns all areas that contain all nodes inside the area specified by `edge1` and `edge2` (inclusive).
|
|
|
|
|
If `accept_overlap` is true, also areas are returned that have nodes in common with the specified area.
|
|
|
|
|
(optional) Boolean values `include_borders` and `include_data` control what's copied.
|
|
|
|
|
* `insert_area(edge1, edge2, data, [id])`: inserts an area into the store. Returns the new area's ID,
|
|
|
|
|
or nil if the insertion failed. The (inclusive) positions `edge1` and `edge2` describe the area.
|
|
|
|
|
`data` is a string stored with the area. If passed, `id` will be used as the internal area ID,
|
|
|
|
|
it must be a unique number between 0 and 2^32-2. If you use the `id` parameter you must always use it,
|
|
|
|
|
or insertions are likely to fail due to conflicts.
|
|
|
|
|
* `reserve(count)`: reserves resources for at most `count` many contained areas.

2014-12-15 20:59:20 +01:00
|
|
|
|
|
|
|
|
|
It can be created via `PseudoRandom(seed)`.

|
* `next()`: return next integer random number [`0`...`32767`]
|
|
|
|
|
* `next(min, max)`: return next integer random number [`min`...`max`]

|
|
|
|
* `((max - min) == 32767) or ((max-min) <= 6553))` must be true

|
|
|
|
due to the simple implementation making bad distribution otherwise.
|
|
|
|
|
|
2015-03-22 05:01:46 +01:00
|
|
|
|
### `PcgRandom`
|
|
|
|
|
A 32-bit pseudorandom number generator.
|
|
|
|
|
Uses PCG32, an algorithm of the permuted congruential generator family, offering very strong randomness.
|
|
|
|
|
|
|
|
|
|
It can be created via `PcgRandom(seed)` or `PcgRandom(seed, sequence)`.
|
|

|
|
|
|
#### Methods
|
|
|
|
|
* `next()`: return next integer random number [`-2147483648`...`2147483647`]

* This is only a rough approximation of a normal distribution with:
|
2017-06-02 14:15:49 +02:00
|
|
|
|
* `mean = (max - min) / 2`, and
|
|
|
|
|
* `variance = (((max - min + 1) ^ 2) - 1) / (12 * num_trials)`
|
|
|
|
|
* Increasing `num_trials` improves accuracy of the approximation

|
|
or `PerlinNoise(noiseparams)`.
|
2014-12-15 20:59:20 +01:00
|
|
|
|
Alternatively with `minetest.get_perlin(seeddiff, octaves, persistence, scale)`
|
|
|
|
|
or `minetest.get_perlin(noiseparams)`.

|
|
|
|
|
#### Methods
|
|
|
|
|
* `get2d(pos)`: returns 2D noise value at `pos={x=,y=}`
|
|
|
|
|
* `get3d(pos)`: returns 3D noise value at `pos={x=,y=,z=}`

|
|
|
|
|
|
|
|
|
### `PerlinNoiseMap`
|
|
|
|
|
A fast, bulk perlin noise generator.
|
|
|
|
|
|
|
|
|
|
It can be created via `PerlinNoiseMap(noiseparams, size)` or
|
|
|
|
|
`minetest.get_perlin_map(noiseparams, size)`.
|
|
|
|
|
|
|
|
|
|
Format of `size` is `{x=dimx, y=dimy, z=dimz}`. The `z` conponent is ommitted
|
|
|
|
|
for 2D noise, and it must be must be larger than 1 for 3D noise (otherwise
|
|
|
|
|
`nil` is returned).
|
|
|
|
|
|
2015-05-17 09:38:39 +02:00
|
|
|
|
For each of the functions with an optional `buffer` parameter: If `buffer` is not
|
|
|
|
|
nil, this table will be used to store the result instead of creating a new table.
|
|
|
|
|
|
|
|
|
|
|
2014-12-15 20:59:20 +01:00
|
|
|
|
#### Methods
|
|
|
|
|
* `get2dMap(pos)`: returns a `<size.x>` times `<size.y>` 2D array of 2D noise
|
|
|
|
|
with values starting at `pos={x=,y=}`
|
|
|
|
|
* `get3dMap(pos)`: returns a `<size.x>` times `<size.y>` times `<size.z>` 3D array
|
|
|
|
|
of 3D noise with values starting at `pos={x=,y=,z=}`
|
2015-05-17 09:38:39 +02:00
|
|
|
|
* `get2dMap_flat(pos, buffer)`: returns a flat `<size.x * size.y>` element array of 2D noise
|
2015-01-10 08:01:54 +01:00
|
|
|
|
with values starting at `pos={x=,y=}`
|
2015-05-17 09:38:39 +02:00
|
|
|
|
* `get3dMap_flat(pos, buffer)`: Same as `get2dMap_flat`, but 3D noise
|
|
|
|
|
* `calc2dMap(pos)`: Calculates the 2d noise map starting at `pos`. The result is stored internally.
|
|
|
|
|
* `calc3dMap(pos)`: Calculates the 3d noise map starting at `pos`. The result is stored internally.
|
|
|
|
|
* `getMapSlice(slice_offset, slice_size, buffer)`: In the form of an array, returns a slice of the
|
|
|
|
|
most recently computed noise results. The result slice begins at coordinates `slice_offset` and
|
|
|
|
|
takes a chunk of `slice_size`.
|
|
|
|
|
E.g. to grab a 2-slice high horizontal 2d plane of noise starting at buffer offset y = 20:
|
|
|
|
|
`noisevals = noise:getMapSlice({y=20}, {y=2})`
|
|
|
|
|
It is important to note that `slice_offset` offset coordinates begin at 1, and are relative to
|
|
|
|
|
the starting position of the most recently calculated noise.
|
|
|
|
|
To grab a single vertical column of noise starting at map coordinates x = 1023, y=1000, z = 1000:
|
|
|
|
|
`noise:calc3dMap({x=1000, y=1000, z=1000})`
|
|
|
|
|
`noisevals = noise:getMapSlice({x=24, z=1}, {x=1, z=1})`

### `VoxelManip`

|
|
|
#### About VoxelManip
|
|
|
|
|
VoxelManip is a scripting interface to the internal 'Map Voxel Manipulator' facility. The purpose of
|
|
|
|
|
this object is for fast, low-level, bulk access to reading and writing Map content. As such, setting
|
|
|
|
|
map nodes through VoxelManip will lack many of the higher level features and concepts you may be used
|
|
|
|
|
to with other methods of setting nodes. For example, nodes will not have their construction and
|
|
|
|
|
destruction callbacks run, and no rollback information is logged.
|
|
|
|
|
|
|
|
|
|
It is important to note that VoxelManip is designed for speed, and *not* ease of use or flexibility.
|
|
|
|
|
If your mod requires a map manipulation facility that will handle 100% of all edge cases, or the use
|
2017-06-02 14:15:49 +02:00
|
|
|
|
of high level node placement features, perhaps `minetest.set_node()` is better suited for the job.
|
2015-11-07 09:27:33 +01:00
|
|
|
|
|
|
|
|
|
In addition, VoxelManip might not be faster, or could even be slower, for your specific use case.
|
|
|
|
|
VoxelManip is most effective when setting very large areas of map at once - for example, if only
|
2017-06-02 14:15:49 +02:00
|
|
|
|
setting a 5x5x5 node area, a `minetest.set_node()` loop may be more optimal. Always profile code
|
2015-11-07 09:27:33 +01:00
|
|
|
|
using both methods of map manipulation to determine which is most appropriate for your usage.
|
|
|
|
|
|
|
|
|
|
#### Using VoxelManip
|
|
|
|
|
A VoxelManip object can be created any time using either:
|
|
|
|
|
`VoxelManip([p1, p2])`, or `minetest.get_voxel_manip([p1, p2])`.
|
|
|
|
|
|
|
|
|
|
If the optional position parameters are present for either of these routines, the specified region
|
|
|
|
|
will be pre-loaded into the VoxelManip object on creation. Otherwise, the area of map you wish to
|
|
|
|
|
manipulate must first be loaded into the VoxelManip object using `VoxelManip:read_from_map()`.
|
|
|
|
|
|
|
|
|
|
Note that `VoxelManip:read_from_map()` returns two position vectors. The region formed by these
|
|
|
|
|
positions indicate the minimum and maximum (respectively) positions of the area actually loaded in
|
|
|
|
|
the VoxelManip, which may be larger than the area requested. For convenience, the loaded area
|
|
|
|
|
coordinates can also be queried any time after loading map data with `VoxelManip:get_emerged_area()`.
|
|
|
|
|
|
|
|
|
|
Now that the VoxelManip object is populated with map data, your mod can fetch a copy of this data
|
|
|
|
|
using either of two methods. `VoxelManip:get_node_at()`, which retrieves an individual node in a
|
|
|
|
|
MapNode formatted table at the position requested is the simplest method to use, but also the slowest.
|
|
|
|
|
|
|
|
|
|
Nodes in a VoxelManip object may also be read in bulk to a flat array table using:
|
|
|
|
|
`VoxelManip:get_data()` for node content (in Content ID form, see section 'Content IDs'),
|
|
|
|
|
`VoxelManip:get_light_data()` for node light levels, and
|
|
|
|
|
`VoxelManip:get_param2_data()` for the node type-dependent "param2" values.
|
|
|
|
|
|
|
|
|
|
See section 'Flat array format' for more details.
|
|
|
|
|
|
|
|
|
|
It is very important to understand that the tables returned by any of the above three functions
|
|
|
|
|
represent a snapshot of the VoxelManip's internal state at the time of the call. This copy of the
|
|
|
|
|
data will *not* magically update itself if another function modifies the internal VoxelManip state.
|
|
|
|
|
Any functions that modify a VoxelManip's contents work on the VoxelManip's internal state unless
|
|
|
|
|
otherwise explicitly stated.
|
|
|
|
|
|
|
|
|
|
Once the bulk data has been edited to your liking, the internal VoxelManip state can be set using:
|
|
|
|
|
`VoxelManip:set_data()` for node content (in Content ID form, see section 'Content IDs'),
|
|
|
|
|
`VoxelManip:set_light_data()` for node light levels, and
|
2017-06-02 14:15:49 +02:00
|
|
|
|

|
|
|
|
|
|
|
|
The parameter to each of the above three functions can use any table at all in the same flat array
|
2017-06-02 14:15:49 +02:00
|
|
|
|
format as produced by `get_data()` et al. and is *not required* to be a table retrieved from `get_data()`.
|
2015-11-07 09:27:33 +01:00
|
|
|
|
|
|
|
|
|
Once the internal VoxelManip state has been modified to your liking, the changes can be committed back
|
|
|
|
|
to the map by calling `VoxelManip:write_to_map()`.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
##### Flat array format
|
|
|
|
|
Let
|
|
|
|
|
`Nx = p2.X - p1.X + 1`,
|
|
|
|
|
`Ny = p2.Y - p1.Y + 1`, and
|
|
|
|
|
`Nz = p2.Z - p1.Z + 1`.
|
|
|
|
|
|
|
|
|
|
Then, for a loaded region of p1..p2, this array ranges from `1` up to and including the value of
|
|
|
|
|
the expression `Nx * Ny * Nz`.
|
|
|
|
|
|
|
|
|
|
Positions offset from p1 are present in the array with the format of:
|
2017-06-02 14:15:49 +02:00
|
|
|
|
|
2015-11-07 09:27:33 +01:00
|
|
|
|
```
|
|
|
|
|
[
|
|
|
|
|
(0, 0, 0), (1, 0, 0), (2, 0, 0), ... (Nx, 0, 0),
|
|
|
|
|
(0, 1, 0), (1, 1, 0), (2, 1, 0), ... (Nx, 1, 0),
|
|
|
|
|
...
|
|
|
|
|
(0, Ny, 0), (1, Ny, 0), (2, Ny, 0), ... (Nx, Ny, 0),
|
|
|
|
|
(0, 0, 1), (1, 0, 1), (2, 0, 1), ... (Nx, 0, 1),
|
|
|
|
|
...
|
|
|
|
|
(0, Ny, 2), (1, Ny, 2), (2, Ny, 2), ... (Nx, Ny, 2),
|
|
|
|
|
...
|
|
|
|
|
(0, Ny, Nz), (1, Ny, Nz), (2, Ny, Nz), ... (Nx, Ny, Nz)
|
|
|
|
|
]
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
and the array index for a position p contained completely in p1..p2 is:
|
|
|
|
|
|
|
|
|
|
`(p.Z - p1.Z) * Ny * Nx + (p.Y - p1.Y) * Nx + (p.X - p1.X) + 1`
|
|
|
|
|
|
|
|
|
|
Note that this is the same "flat 3D array" format as `PerlinNoiseMap:get3dMap_flat()`.
|
|
|
|
|
VoxelArea objects (see section 'VoxelArea') can be used to simplify calculation of the index
|
|
|
|
|
for a single point in a flat VoxelManip array.
|
|
|
|
|
|
|
|
|
|
##### Content IDs
|
|
|
|
|
A Content ID is a unique integer identifier for a specific node type. These IDs are used by VoxelManip
|
|
|
|
|
in place of the node name string for `VoxelManip:get_data()` and `VoxelManip:set_data()`. You can use
|
|
|
|
|
`minetest.get_content_id()` to look up the Content ID for the specified node name, and
|
|
|
|
|
`minetest.get_name_from_content_id()` to look up the node name string for a given Content ID.
|
|
|
|
|
After registration of a node, its Content ID will remain the same throughout execution of the mod.
|
|
|
|
|
Note that the node being queried needs to have already been been registered.
|
|
|
|
|
|
|
|
|
|
The following builtin node types have their Content IDs defined as constants:
|
2017-06-02 14:15:49 +02:00
|
|
|
|
|
|
|
|
|
* `minetest.CONTENT_UNKNOWN`: ID for "unknown" nodes
|
|
|
|
|
* `minetest.CONTENT_AIR`: ID for "air" nodes
|
|
|
|
|
* `minetest.CONTENT_IGNORE`: ID for "ignore" nodes
|
2015-11-07 09:27:33 +01:00
|
|
|
|
|
|
|
|
|
##### Mapgen VoxelManip objects
|
|
|
|
|
Inside of `on_generated()` callbacks, it is possible to retrieve the same VoxelManip object used by the
|
|
|
|
|
core's Map Generator (commonly abbreviated Mapgen). Most of the rules previously described still apply
|
|
|
|
|
but with a few differences:
|
2015-12-07 07:26:12 +01:00
|
|
|
|
|
2015-11-07 09:27:33 +01:00
|
|
|
|
* The Mapgen VoxelManip object is retrieved using: `minetest.get_mapgen_object("voxelmanip")`
|
|
|
|
|
* This VoxelManip object already has the region of map just generated loaded into it; it's not necessary
|
|
|
|
|
to call `VoxelManip:read_from_map()` before using a Mapgen VoxelManip.
|
|
|
|
|
* The `on_generated()` callbacks of some mods may place individual nodes in the generated area using
|
|
|
|
|
non-VoxelManip map modification methods. Because the same Mapgen VoxelManip object is passed through
|
|
|
|
|
each `on_generated()` callback, it becomes necessary for the Mapgen VoxelManip object to maintain
|
|
|
|
|
consistency with the current map state. For this reason, calling any of the following functions:
|
|
|
|
|
`minetest.add_node()`, `minetest.set_node()`, or `minetest.swap_node()`
|
|
|
|
|
will also update the Mapgen VoxelManip object's internal state active on the current thread.
|
|
|
|
|
* After modifying the Mapgen VoxelManip object's internal buffer, it may be necessary to update lighting
|
|
|
|
|
information using either: `VoxelManip:calc_lighting()` or `VoxelManip:set_lighting()`.
|
|
|
|
|
|
|
|
|
|
##### Other API functions operating on a VoxelManip
|
|
|
|
|
If any VoxelManip contents were set to a liquid node, `VoxelManip:update_liquids()` must be called
|
|
|
|
|
for these liquid nodes to begin flowing. It is recommended to call this function only after having
|
|
|
|
|
written all buffered data back to the VoxelManip object, save for special situations where the modder
|
|
|
|
|
desires to only have certain liquid nodes begin flowing.
|
|
|
|
|
|
|
|
|
|
The functions `minetest.generate_ores()` and `minetest.generate_decorations()` will generate all
|
|
|
|
|
registered decorations and ores throughout the full area inside of the specified VoxelManip object.
|
|
|
|
|
|
|
|
|
|
`minetest.place_schematic_on_vmanip()` is otherwise identical to `minetest.place_schematic()`,
|
|
|
|
|
except instead of placing the specified schematic directly on the map at the specified position, it
|
|
|
|
|
will place the schematic inside of the VoxelManip.
|
|
|
|
|
|
|
|
|
|
##### Notes
|
|
|
|
|
* Attempting to read data from a VoxelManip object before map is read will result in a zero-length
|
|
|
|
|
array table for `VoxelManip:get_data()`, and an "ignore" node at any position for
|
|
|
|
|
`VoxelManip:get_node_at()`.
|
|
|
|
|
* If either a region of map has not yet been generated or is out-of-bounds of the map, that region is
|
|
|
|
|
filled with "ignore" nodes.
|
|
|
|
|
* Other mods, or the core itself, could possibly modify the area of map currently loaded into a VoxelManip
|
|
|
|
|
object. With the exception of Mapgen VoxelManips (see above section), the internal buffers are not
|
|
|
|
|
updated. For this reason, it is strongly encouraged to complete the usage of a particular VoxelManip
|
|
|
|
|
object in the same callback it had been created.
|
|
|
|
|
* If a VoxelManip object will be used often, such as in an `on_generated()` callback, consider passing
|
|
|
|
|
a file-scoped table as the optional parameter to `VoxelManip:get_data()`, which serves as a static
|
|
|
|
|
buffer the function can use to write map data to instead of returning a new table each call. This
|
|
|
|
|
greatly enhances performance by avoiding unnecessary memory allocations.

|
|
|
|
|
It can be created via `VoxelArea:new{MinEdge=pmin, MaxEdge=pmax}`.

### `Raycast`
|
|
|
|
|
A raycast on the map. It works with selection boxes.
|
|
|
|
|
Can be used as an iterator in a for loop.
|
|
|
|
|
|
|
|
|
|
The map is loaded as the ray advances. If the
|
|
|
|
|
map is modified after the `Raycast` is created,
|
|
|
|
|
the changes may or may not have an effect on
|
|
|
|
|
the object.
|
|
|
|
|
|
|
|
|
|
It can be created via `Raycast(pos1, pos2, objects, liquids)` or
|
|
|
|
|
`minetest.raycast(pos1, pos2, objects, liquids)` where:
|
|
|
|
|
* `pos1`: start of the ray
|
|
|
|
|
* `pos2`: end of the ray
|
|
|
|
|
* `objects` : if false, only nodes will be returned. Default is true.
|
|
|
|
|
* `liquids' : if false, liquid nodes won't be returned. Default is false.
|
|
|
|
|
|
|
|
|
|
#### Methods
|
|
|
|
|
* `next()`: returns a `pointed_thing`
|
|
|
|
|
* Returns the next thing pointed by the ray or nil.

Mapgen objects
|
2014-12-15 20:59:20 +01:00
|
|
|
|
--------------
|
2015-02-22 18:12:55 +01:00
|
|
|
|
A mapgen object is a construct used in map generation. Mapgen objects can be used
|
|
|
|
|
by an `on_generate` callback to speed up operations by avoiding unnecessary
|
|
|
|
|
recalculations; these can be retrieved using the `minetest.get_mapgen_object()`
|
|
|
|
|
function. If the requested Mapgen object is unavailable, or `get_mapgen_object()`
|
|
|
|
|

2014-12-15 20:59:20 +01:00
|
|
|
|
-------------------
|
|
|
|
|
* Functions receive a "luaentity" as `self`:
|
|
|
|
|
* It has the member `.name`, which is the registered name `("mod:thing")`
|
|
|
|
|
* It has the member `.object`, which is an `ObjectRef` pointing to the object
|
|
|
|
|
* The original prototype stuff is visible directly via a metatable
|
|
|
|
|
* Callbacks:
|
2016-09-08 20:42:08 +02:00
|
|
|
|
* `on_activate(self, staticdata, dtime_s)`
|
2014-12-15 20:59:20 +01:00
|
|
|
|
* Called when the object is instantiated.
|
2016-09-08 20:42:08 +02:00
|
|
|
|
* `dtime_s` is the time passed since the object was unloaded, which can
|
|
|
|
|
be used for updating the entity state.
|
2014-12-15 20:59:20 +01:00
|
|
|
|
* `on_step(self, dtime)`
|
|
|
|
|
* Called on every server tick, after movement and collision processing.
|
|
|
|
|
`dtime` is usually 0.1 seconds, as per the `dedicated_server_step` setting
|
|
|
|
|
`in minetest.conf`.
|
2016-09-08 20:42:08 +02:00
|
|
|
|
* `on_punch(self, puncher, time_from_last_punch, tool_capabilities, dir)`
|
2014-12-15 20:59:20 +01:00
|
|
|
|
* Called when somebody punches the object.
|
|
|
|
|
* Note that you probably want to handle most punches using the
|
|
|
|
|
automatic armor group system.
|
|
|
|
|
* `puncher`: an `ObjectRef` (can be `nil`)
|
|
|
|
|
* `time_from_last_punch`: Meant for disallowing spamming of clicks (can be `nil`)
|
|
|
|
|
* `tool_capabilities`: capability table of used tool (can be `nil`)
|
|
|
|
|
* `dir`: unit vector of direction of punch. Always defined. Points from
|
|
|
|
|
the puncher to the punched.
|
2017-07-27 11:32:35 +02:00
|
|
|
|
`on_death(self, killer)`
|
|
|
|
|
* Called when the object dies.
|
|
|
|
|
* `killer`: an `ObjectRef` (can be `nil`)
|
2014-12-15 20:59:20 +01:00
|
|
|
|
* `on_rightclick(self, clicker)`
|
|
|
|
|
* `get_staticdata(self)`
|
|
|
|
|
* Should return a string that will be passed to `on_activate` when
|
|
|
|
|
the object is instantiated the next time.

|
|
**Warning**
|
|
|
|
|
L-system generation currently creates lighting bugs in the form of mapblock-sized shadows.
|
|
|
|
|
Often these bugs appear as subtle shadows in water.

Nodebox: Allow nodeboxes to "connect"
We introduce a new nodebox type "connected", and allow these nodes to
have optional nodeboxes that connect it to other connecting nodeboxes.
This is all done at scenedraw time in the client. The client will
inspect the surrounding nodes and if they are to be connected to,
it will draw the appropriate connecting nodeboxes to make those
connections.
In the node_box definition, we have to specify separate nodeboxes for
each valid connection. This allows us to make nodes that connect only
horizontally (the common case) by providing optional nodeboxes for +x,
-x, +z, -z directions. Or this allows us to make wires that can connect
up and down, by providing nodeboxes that connect it up and down (+y,
-y) as well.
The optional nodeboxes can be arrays. They are named "connect_top,
"connect_bottom", "connect_front", "connect_left", "connect_back" and
"connect_right". Here, "front" means the south facing side of the node
that has facedir = 0.
Additionally, a "fixed" nodebox list present will always be drawn,
so one can make a central post, for instance. This "fixed" nodebox
can be omitted, or it can be an array of nodeboxes.
Collision boxes are also updated in exactly the same fashion, which
allows you to walk over the upper extremities of the individual
node boxes, or stand really close to them. You can also walk up
node noxes that are small in height, all as expected, and unlike the
NDT_FENCELIKE nodes.
I've posted a screenshot demonstrating the flexibility at
http://i.imgur.com/zaJq8jo.png
In the screenshot, all connecting nodes are of this new subtype.
Transparent textures render incorrectly, Which I don't think is
related to this text, as other nodeboxes also have issues with this.
A protocol bump is performed in order to be able to send older clients
a nodeblock that is usable for them. In order to avoid abuse of users
we send older clients a "full-size" node, so that it's impossible for
them to try and walk through a fence or wall that's created in this
fashion. This was tested with a pre-bump client connected against a
server running the new protocol.
These nodes connect to other nodes, and you can select which ones
those are by specifying node names (or group names) in the
connects_to string array:
connects_to = { "group:fence", "default:wood" }
By default, nodes do not connect to anything, allowing you to create
nodes that always have to be paired in order to connect. lua_api.txt
is updated to reflect the extension to the node_box API.
Example lua code needed to generate these nodes can be found here:

Allow nodes to specify which sides to connect to.
NDT_CONNECTED attempts to connect to any side of nodes that it can
connect to, which is troublesome for FACEDIR type nodes that generally
may only have one usable face, and can be rotated.
We introduce a node parameter `connect_sides` that is valid for
any node type. If specified, it lists faces of the node (in "top",
"bottom", "front", "left", "back", "right", form, as array) that
connecting nodeboxes can connect to. "front" corresponds to the south
facing side of a node with facedir = 0.
If the node is rotatable using *simple* FACEDIR, then the attached
face is properly rotated before checking. This allows e.g. a chest
to be attached to only from the rear side.
