@ -1553,17 +1553,23 @@ VoxelManip: An interface to the MapVoxelManipulator for Lua
- Can be created via VoxelManip()
- Also minetest.get_voxel_manip()
methods:
- read_chunk(p1, p2): Read a chunk of map containing the region formed by p1 and p2.
^ returns raw node data, actual emerged p1, actual emerged p2
^ raw node data is in the form of a table mapping indicies to node content ids
- write_chunk(data): Write back the data
- update_map(): Update map after writing chunk.
^ To be used only by VoxelManip objects created by the mod itself; not VoxelManips passed to callbacks
- read_from_map(p1, p2): Reads a chunk of map from the map containing the region formed by p1 and p2.
^ returns actual emerged pmin, actual emerged pmax
- write_to_map(): Writes the data loaded from the VoxelManip back to the map.
^ important: data must be set using VoxelManip:set_data before calling this
- get_data(): Gets the data read into the VoxelManip object
^ returns raw node data is in the form of an array of node content ids
- set_data(data): Sets the data contents of the VoxelManip object
- update_map(): Update map after writing chunk back to map.
^ To be used only by VoxelManip objects created by the mod itself; not a VoxelManip that was
^ retrieved from minetest.get_mapgen_object
- set_lighting(p1, p2, light): Set the lighting in the region formed by p1 and p2 to light
^ light is a table containing two integer fields ranging from 0 to 15, day and night
^ To be used only by VoxelManip objects passed to a callback; otherwise, set lighting will be ignored
^ To be used only by a VoxelManip object from minetest.get_mapgen_object; otherwise, set lighting will
^ be ignored
- calc_lighting(p1, p2): Calculate lighting in the region formed by p1 and p2
^ To be used only by VoxelManip objects passed to a callback; otherwise, calculated lighting will be ignored
^ To be used only by a VoxelManip object from minetest.get_mapgen_object; otherwise, calculated lighting
^ will be ignored
- update_liquids(): Update liquid flow
Mapgen objects
