- 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(light): Set the lighting within the VoxelManip
- set_lighting(light, p1, p2): Set the lighting within the VoxelManip to a uniform value
^ light is a table, {day=<0...15>, night=<0...15>}
^ To be used only by a VoxelManip object from minetest.get_mapgen_object
^ (p1, p2) is the area in which lighting is set; defaults to the whole area if left out
- get_light_data(): Gets the light data read into the VoxelManip object
^ Returns an array (indicies 1 to volume) of integers ranging from 0 to 255
^ Each value is the bitwise combination of day and night light values (0..15 each)
^ light = day + (night * 16)
- set_light_data(light_data): Sets the param1 (light) contents of each node in the VoxelManip
^ expects lighting data in the same format that get_light_data() returns
- calc_lighting(): Calculate lighting within the VoxelManip
- calc_lighting(p1, p2): Calculate lighting within the VoxelManip
^ To be used only by a VoxelManip object from minetest.get_mapgen_object
