set_structure()
Syntax
set_structure(pos, structure_name)
set_structure(pos, structure_name, null)
Creates or removes structure information of a structure associated with a chunk
of pos. Unlike plop, blocks are not placed in the world, only structure
information is set. For the game this is a fully functional structure even if
blocks are not set. To remove the structure a given point is in, use
structure_references to find where current structure starts.
Requires a Structure Variant or Standard Structure name (see above). If
standard name is used, the variant of the structure may depend on the biome,
otherwise the default structure for this type will be generated.
Throws unknown_structure if structure doesn’t exist.
