This adds support for optional “off state” icons for statbars. “off state icons” can be used to denote the lack of something, like missing hearts or bubbles. Add "off state" textures to the builtin statbars. Co-authored-by: SmallJoker <mk939@ymail.com>

Minetest Texture Pack Reference
|
||
===============================
|
||
|
||
Texture packs allow you to replace textures provided by a mod with your own
|
||
textures.
|
||
|
||
Texture pack directory structure
|
||
--------------------------------
|
||
|
||
textures
|
||
|-- Texture Pack
|
||
| |-- texture_pack.conf
|
||
| |-- screenshot.png
|
||
| |-- description.txt
|
||
| |-- override.txt
|
||
| |-- your_texture_1.png
|
||
| |-- your_texture_2.png
|
||
`-- Another Texture Pack
|
||
|
||
### Texture Pack
|
||
This is a directory containing the entire contents of a single texture pack.
|
||
It can be chosen more or less freely and will also become the name of the
|
||
texture pack. The name must not be “base”.
|
||
|
||
### `texture_pack.conf`
|
||
A key-value config file with the following keys:
|
||
|
||
* `title` - human readable title
|
||
* `description` - short description, shown in the content tab
|
||
|
||
### `description.txt`
|
||
**Deprecated**, you should use texture_pack.conf instead.
|
||
|
||
A file containing a short description of the texture pack to be shown in the
|
||
content tab.
|
||
|
||
### `screenshot.png`
|
||
A preview image showing an in-game screenshot of this texture pack; it will be
|
||
shown in the texture packs tab. It should have an aspect ratio of 3:2 and a
|
||
minimum size of 300×200 pixels.
|
||
|
||
### `your_texture_1.png`, `your_texture_2.png`, etc.
|
||
Any other PNG files will be interpreted as textures. They must have the same
|
||
names as the textures they are supposed to override. For example, to override
|
||
the apple texture of Minetest Game, add a PNG file named `default_apple.png`.
|
||
|
||
The custom textures do not necceessarily require the same size as their
|
||
originals, but this might be required for a few particular textures. When
|
||
unsure, just test your texture pack in-game.
|
||
|
||
Texture modifiers
|
||
-----------------
|
||
|
||
See lua_api.txt for texture modifiers
|
||
|
||
Special textures
|
||
----------------
|
||
|
||
These texture names are hardcoded into the engine but can also be overwritten
|
||
by texture packs. All existing fallback textures can be found in the directory
|
||
`textures/base/pack`.
|
||
|
||
### Gameplay textures

Texture Overrides
|
||
-----------------
|
||
|
||
You can override the textures of nodes and items from a
|
||
texture pack using texture overrides. To do this, create one or
|
||
more files in a texture pack called override.txt
|
||
|
||
Each line in an override.txt file is a rule. It consists of
|
||
|
||
itemname target texture
|
||
|
||
For example,
|
||
|
||
default:dirt_with_grass sides default_stone.png
|
||
|
||
or
|
||
|
||
default:sword_steel inventory my_steel_sword.png
|
||
|
||
You can list multiple targets on one line as a comma-separated list:
|
||
|
||
default:tree top,bottom my_special_tree.png
|
||
|
||
You can use texture modifiers, as usual:
|
||
|
||
default:dirt_with_grass sides default_stone.png^[brighten
|
||
|
||
Finally, if a line is empty or starts with '#' it will be considered
|
||
a comment and not read as a rule. You can use this to better organize
|
||
your override.txt files.
|
||
|
||
Here are targets you can choose from:
|
||
|
||
| target | behavior |
|
||
|---------------|---------------------------------------------------|
|
||
| left | x- face |
|
||
| right | x+ face |
|
||
| front | z- face |
|
||
| back | z+ face |
|
||
| top | y+ face |
|
||
| bottom | y- face |
|
||
| sides | x-, x+, z-, z+ faces |
|
||
| all | All faces. You can also use '*' instead of 'all'. |
|
||
| inventory | The inventory texture |
|
||
| wield | The texture used when held by the player |
|
||
|
||
Nodes support all targets, but other items only support 'inventory'
|
||
and 'wield'
|
||
|
||
Designing leaves textures for the leaves rendering options
|
||
----------------------------------------------------------
|
||
|
||
Minetest has three modes for rendering leaves nodes if the node has the
|
||
`allfaces_optional` drawtype.
|
||
|
||
### Fancy
|
||
|
||
Uses the texture specified in the `tiles` nodedef field.
|
||
The texture should have some transparent pixels and be in the RGBA format so
|
||
that the transparent pixels can have color information.
|
||
Faces of every leaves node are rendered even if they are inside a solid volume
|
||
of leaves; this gives a dense appearance.
|
||
|
||
### Opaque
|
||
|
||
Uses the texture specified in `tiles` but makes it opaque by converting each
|
||
transparent pixel into an opaque pixel that uses the color information of that
|
||
transparent pixel.
|
||
Due to this the `tiles` texture format must be RGBA not 'indexed alpha' to allow
|
||
each transparent pixel to have color information.
|
||
|
||
The colors of the transparent pixels should be set for a good appearance in
|
||
`opaque` mode. This can be done by painting the pixels the desired colors then
|
||
erasing them. Then when saving the texture, use the 'save color information from
|
||
transparent pixels' option (or equivalent).
|
||
|
||
### Simple
|
||
|
||
Uses the texture specified in the `special_tiles` nodedef field if it exists, if
|
||
not, the `tiles` texture.
|
||
The `special_tiles` texture should have fewer transparent pixels than the
|
||
`tiles` texture and be in the 'indexed alpha' format.
|
||
|
||
This mode is between the other two in terms of appearance and rendering load.
|
||
The nodes are rendered using the `glasslike` drawtype, only showing the surface
|
||
faces for any solid volume of leaves, not the internal faces.
|
||
Due to this the `tiles` texture might appear lacking in density, so optionally a
|
||
`special_tiles` texture can be used to provide a texture with fewer transparent
|
||
pixels for a denser appearance.
