set_biome()

Syntax

set_biome(pos, biome_name, updatetrue)

Changes the biome at that block position. if update is specified and false, then chunk will not be refreshed on the clients. Biome changes can only be sent to clients with the entire data from the chunk.

Be aware that depending on the MC version and dimension settings biome can be set either in a 1x1x256 column or 4x4x4 hyperblock, so for some versions Y will be ignored and for some precision of biome setting is less than 1x1x1 block.

Throws unknown_biome if the biome_name doesn’t exist.
