Returns an array containing the humidity values of nodes in the most recently generated chunk by the
current mapgen.
- gennotify
Returns a table mapping requested generation notification types to arrays of positions at which the
corresponding generated structures are located at within the current chunk. To set the capture of positions
of interest to be recorded on generate, use minetest.set_gen_notify().
Possible fields of the table returned are: dungeon, temple, cave_begin, cave_end, large_cave_begin, large_cave_end
