minetest.get_voxel_manip()
^ Return voxel manipulator object
minetest.get_voxel_manip(p1, p2)
-^ Return voxel manipulator object with blank data preallocated
+^ Return voxel manipulator object with map pre-loaded
minetest.set_gen_notify(flags, {deco_ids})
^ Set the types of on-generate notifications that should be collected
^ flags is a flag field with the available flags:
VoxelManip: An interface to the MapVoxelManipulator for Lua
- Can be created via VoxelManip()
- Also minetest.get_voxel_manip()
-- Specify a pmin, pmax in either to allocate a blank chunk of data prefilled with cignore
+- Specify a pmin, pmax to create a VoxelManip with map already loaded
methods:
- 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
