The game directory can contain the file minetest.conf, which will be used
to set default settings when running the particular game.
+### Menu images
+
+Games can provide custom main menu images. They are put inside a `menu` directory inside the game directory.
+
+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.

#### 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=}`
-* `get2dMap_flat(pos)`: returns a flat `<size.x * size.y>` element array of 2D noise
+* `get2dMap_flat(pos, buffer)`: returns a flat `<size.x * size.y>` element array of 2D noise
with values starting at `pos={x=,y=}`
- * if the param `buffer` is present, this table will be used to store the result instead
-* `get3dMap_flat(pos)`: Same as `get2dMap_flat`, but 3D noise
- * if the param `buffer` is present, this table will be used to store the result instead
+* `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`
An interface to the `MapVoxelManipulator` for Lua.
### Tile definition
* `"image.png"`
* `{name="image.png", animation={Tile Animation definition}}`
-* `{name="image.png", backface_culling=bool}`
- * backface culling only supported in special tiles
+* `{name="image.png", backface_culling=bool, tileable_vertical=bool,
+ tileable_horizontal=bool}`
+ * backface culling only supported in special tiles.
+ * tileable flags are info for shaders, how they should treat texture
+ when displacement mapping is used
+ Directions are from the point of view of the tile texture,
+ not the node it's on
* deprecated, yet still supported field names:
* `image` (name)
-- ^ Number of nodes the decoration can be at maximum.
-- ^ If absent, the parameter 'height' is used as a constant.
spawn_by = "default:water",
- -- ^ Node that the decoration only spawns next to, in a 1-node square radius.
+ -- ^ Node that the decoration only spawns next to.
+ -- ^ The neighbours checked are the 8 nodes horizontally surrounding the lowest node of the
+ -- ^ decoration, and the 8 nodes horizontally surrounding the ground node below the decoration.
num_spawn_by = 1,
-- ^ Number of spawn_by nodes that must be surrounding the decoration position to occur.
-- ^ If absent or -1, decorations occur next to any nodes.
