Physical_structures API
by ModsOverlord
Physical_structures API lets mods generate physics-enabled structures for Create Aeronautics and Sable during world generation.
What it does
The API adds NBT tags to structures in the overworld while they generate, so the generated structures become physical objects. It is meant for use with Create Aeronautics and Sable, and the NeoForge build covers game version 1.21.1 only. The mod runs on client and server, so both sides need it, and it is released under the MIT License without being open source.
