Useful for underwater plants.
Node consists of a base cube plus a plantlike extension that can pass through
liquid nodes above without creating air bubbles or interfering with liquid flow.
Uses paramtype2 'leveled', param2 defines height of plantlike extension.
This commit introduces Raycast, a Lua user object, which can be
used to perform a raycast on the map. The ray is continuable, so one can
also get hidden nodes (for example to see trough glass).
* Load client-side mods into memory before executing them.
This removes the remaining filesystem access that client-sided mods had and it will hopefully make then more secure.
* Lua Virtual filesystem: don't load the files into memory just scan the filenames into memory.
* Fix the issues with backtrace
* fix most of the issues
* fix code style.
* add a comment
C++11 implement function deleting, it's generally used to prevent some object copy
In script API use this function removal on ScriptApiBase instead of ScriptApiClient/Server/MainMenu, this affect all ScriptApis
Move DISABLE_CLASS_COPY with constructor, the deleted function permit to replace function in its original place
This unifies the settings APIs.
This also unifies the sync and async registration APIs, since the async
registration API did not support adding non-functions to the API table.
* Fix various performance issues reported by cppcheck + code style (CI)
* Make CI happy with code style on master
* guiFileSelectMenu: remove useless includes
* some performance fixes pointed by cppcheck
* remove some useless casts
* TextDest: remove unused setFormSpec function
* Fix various iterator post-increment reported by cppcheck
This callback is called if a liquid definitely floods a non-air
node on the map. The callback arguments are (pos, oldnode, newnode)
and can return a `bool` value indicating whether flooding the
node should be cancelled (`return true` will prevent the node
from flooding).
Documentation is added, the callback function was tested with a
modified minetest_game.
Note that `return true` will likely cause the node's `on_flood()`
callback to be called every second until the node gets removed,
so care must be taken to prevent many callbacks from using this
return value. The current default liquid update interval is 1.0
seconds, which isn't unmanageable.
The larger aim of this patch is to remove the lava cooling ABM,
which is a significant cost to idle servers that have lava on their
map. This callback will be much more efficient.
* Resource leak: CHECK_FILE_ERR returns, without freeing chunk_name.
Found with static analysis.
* Resource leak: leaks `page` on error path.
Found with static analysis.
Adds the possibility to colorize item stacks based on their metadata.
In the item/node definition you can specify palette (an image file)
and color (fallback color if the item has no palette or metadata).
Then you can add palette_index to the metadata.
Dropped itemstacks with different colors do not merge.
Add the missing paramtype2 for param2 controlling the liquid level
inside the glasslike_framed drawtype.
Add missing documentation of the feature to lua_api.txt.
Update and improve comments for drawtype enumerations in nodedef.h.
* squashed: CSM: Implement register_globalstep
* Re-use fatal error mechanism from server to disconnect client on CSM error
* Little client functions cleanups
* squashed: CSM: add core.after function
* core.after is shared code between client & server
* ModApiUtil get_us_time feature enabled for client
* rename GameScripting to ServerScripting
* Make getBuiltinLuaPath static serverside
* Add on_shutdown callback
* Add on_receiving_chat_message & on_sending_chat_message callbacks
* ScriptApiBase: use IGameDef instead of Server
This permits to share common attribute between client & server
* Enable mod security in client side modding without conditions
- Increase ContentFeatures serialization version
- Color property and palettes for nodes
- paramtype2 = "color", "colored facedir" or "colored wallmounted"
Currently, lua does a regular exit() after a lua panic, which can make
a problem hard to debug. Invoking FATAL_ERROR() instead will print
some useful information, and abort() minetest, so that a debugger can
be used to analyze the situation.
Trying to resolve a path with RemoveRelativePathComponents that can't
be resolved without leaving leading parent components (e.g. "../worlds/foo"
or "bar/../../worlds/foo") will fail. To work around this, we leave
the relative components and simply remove the trailing components one
at a time, and bail out when we find a parent component. This will
still fail for paths like "worlds/foo/noexist/../auth.txt" (the path
before the last parent component must not exist), but this is fine
since you won't be able to open a file with a path like that anyways
(the O.S. will determine that the path doesn't exist.
Try `cat /a/../etc/passwd`).
Modification of the emergeblocks internal state was not protected
by a lock, causing a race condition.
This can be reproduced by repeatedly running emergeblocks for an
already-generated section of the map (with multiple emerge threads).
Adds several new ways that the plantlike drawtype mesh can be changed.
This requires paramtype2 = "meshoptions" to be set in the node
definition. The drawtype for these nodes should be "plantlike".
These modifications are all done using param2. This field is now
a complex bitfield that allows some or more of the combinations to
be chosen, and the mesh draw code will choose the options based as
neeeded for each plantlike node.
bit layout:
bits 0, 1 and 2 (values 0x1 through 0x7) are for choosing the plant
mesh shape:
0 - ordinary plantlike plant ("x" shaped)
1 - ordinary plant, but rotated 45 degrees ("+" shaped)
2 - a plant with 3 faces ("*" shaped)
3 - a plant with 4 faces ("#" shaped)
4 - a plant with 4 faces ("#" shaped, leaning outwards)
5 through 7 are unused and reserved for future mesh shapes.
bit 3 (0x8) causes the plant to be randomly offset in the x,z
plane. The plant should fall within the 1x1x1 nodebox if regularly
sized.
bit 4 (0x10) causes the plant mesh to grow by sqrt(2), and will cause
the plant mesh to fill out 1x1x1, and appear slightly larger. Texture
makers will want to make their plant texture 23x16 pixels to have the
best visual fit in 1x1x1 size.
bit 5 (0x20) causes each face of the plant to have a slight negative
Y offset in position, descending up to 0.125 downwards into the node
below. Because this is per face, this causes the plant model to be
less symmetric.
bit 6 (0x40) through bit 7 (0x80) are unused and reserved for
future use.
