- update_liquids(): Update liquid flow
VoxelArea: A helper class for voxel areas
- Can be created via VoxelArea:new{MinEdge=pmin, MaxEdge=pmax}
- Coordinates are *inclusive*, like most other things in Minetest
methods:
- getExtent(): returns a 3d vector containing the size of the area formed by MinEdge and MaxEdge
- getVolume(): returns the volume of the area formed by MinEdge and MaxEdge
- index(x, y, z): returns the index of an absolute position in a flat array starting at 1
^ useful for things like VoxelManip, raw Schematic specifiers, PerlinNoiseMap:get2d/3dMap, and so on
- indexp(p): same as above, except takes a vector
