Inventory location:
- "context": Selected node metadata (deprecated: "current_name")

+^ Leave field unset to leave that parameter unchanged
+^ flagmask field must be set to all mapgen flags that are being modified
+^ flags contains only the flags that are being set
+^ flags and flagmask are in the same format and have the same options as 'mgflags' in minetest.conf
minetest.clear_objects()
^ clear all objects in the environments
minetest.line_of_sight(pos1,pos2,stepsize) ->true/false

-minetest.place_schematic(pos, schematic)
+minetest.place_schematic(pos, schematic, rotation)
^ Place the schematic specified by schematic (see: Schematic specifier) at pos.
+^ Rotation can be "0", "90", "180", "270", or "random".
+^ If the rotation parameter is omitted, the schematic is not rotated.
Random:
minetest.get_connected_players() -> list of ObjectRefs
^ Get rating of a group of an item. (0 = not in group)
minetest.get_node_group(name, group) -> rating
^ Deprecated: An alias for the former.
+minetest.get_content_id(name) -> integer

+PerlinNoiseMap: A fast, bulk perlin noise generator

+- Also minetest.get_perlin_map(noiseparams, size)
+methods:

+- get3dMap(pos) -> <size.x>X<size.y>X<size.z> 3d array of 3d noise values starting at pos={x=,y=,z=}
+- get2dMap_flat(pos) -> Flat <size.x * size.y> element array of 2d noise values starting at pos={x=,y=}

+
+VoxelManip: An interface to the MapVoxelManipulator for Lua
+- Can be created via VoxelManip()
+- Also minetest.get_voxel_manip()
+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
+- write_to_map(): Writes the data loaded from the VoxelManip back to the map.
+ ^ important: data must be set using VoxelManip:set_data before calling this
+- get_data(): Gets the data read into the VoxelManip object
+ ^ returns raw node data is in the form of an array of node content ids
+- set_data(data): Sets the data contents of the VoxelManip object
+- 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
+ ^ light is a table, {day=<0...15>, night=<0...15>}
+ ^ To be used only by a VoxelManip object from minetest.get_mapgen_object

+
+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
+
+Mapgen objects
+---------------
+A mapgen object is a construct used in map generation. Mapgen objects can be used 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.
+
+The following Mapgen objects are currently available:
+
+- voxelmanip
+ This returns three values; the VoxelManip object to be used, minimum and maximum emerged position, in that
+order. All mapgens support this object.
+
+- 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.
+
Registered entities
--------------------
- Functions receive a "luaentity" as self:
^ See 'Schematic specifier' for details.
flags = "place_center_x, place_center_z",
^ Flags for schematic decorations. See 'Schematic attributes'.
+ rotation = "90" --rotate schematic 90 degrees on placement
+ ^ Rotation can be "0", "90", "180", "270", or "random".
