The Biome API is still in an experimental phase and subject to change.

Description

Biomes are areas of similar features such as schematics or ground content. They define what nodes will be used for certain features, and also the heat & humidity of an area, among other things.

Usage

New biomes can be created with minetest.register_biome

Syntax

        node_dust = "modname:dust",                      -- the node to be set on top of the biome once other decorations are placed

        node_stone = "modname:stone",                    -- the node to be used instead of mapgen_stone (does not extend very deep)
        node_water_top = "modname:ice",                  -- the node to replace the top layers of node_water
        depth_water_top = 10,                            -- how many layers of water to replace with node_water_top

        y_max = 31000,                                   -- the upper limit of the biome (features will not generate above this level)
        heat_point = 0,                                  -- how the biome is
