-A mapgen object is a construct used in map generation. Mapgen objects can be used
+{{UnofficialLua}}
-by an `on_generate` callback to speed up operations by avoiding unnecessary
-recalculations; these can be retrieved using the `[[minetest.get_mapgen_object]]()`
-function. If the requested Mapgen object is unavailable, or `get_mapgen_object()`
-was called outside of an `on_generate()` callback, `nil` is returned.
-=== voxelmanip ===
+Please see https://minetest.gitlab.io/minetest/mapgen-objects/#mapgen-objects
-This returns three values; the `VoxelManip` object to be used, minimum and maximum
-emerged position, in that order. All mapgens support this object.
-Currently the emerged positions contain a [[mapblock]] outside the field of minp and maxp in every direction.
-=== heightmap ===
-Returns an array containing the y coordinates of the ground levels of nodes in
-the most recently generated chunk by the current mapgen.
-=== biomemap ===
-Returns an array containing the biome IDs of nodes in the most recently
-generated chunk by the current mapgen.
-=== heatmap ===
-Returns an array containing the temperature values of nodes in the most
-recently generated chunk by the current mapgen.
-=== humiditymap ===
-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`
-* `decoration`
-Decorations have a key in the format of `"decoration#id"`, where `id` is the
-numeric unique decoration ID.
