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
