Rayon
by BlueVista
Rayon is a Library that gives Minecraft a rigid body physics simulation for custom entities, built on Bullet Physics.
What it does
Rayon simulates motion for custom entities alongside Minecraft's original physics, so entities added by other mods can move as rigid bodies under Bullet Physics. It works with Fabric API and needs it on Fabric. The library runs on client and server, so both the server and every player need it. Builds are published for Fabric and Forge, covering 1.19 – 1.20.1 with six release versions, and the code is open source under the MIT License.
Dropz requires Rayon, so installing that mod also means installing this library. The latest files are 1.7.2+1.20.1 for both Fabric and Forge, dated 2023-07-30, and the project has a source code repository, an issue tracker and a wiki.

Library for other mods
