This package lets you simulate physics in unity using Rapier.
This is useful for when you want to run physics in non-unity clients for validation. E.g. Server Authoritive setup with client side prediction. An example of excellent use is running Rapier on a SpaceTimeDB server, and when syncing it with a client also running Rapier.

Note how it acts just like normal Unity! and it even supports raycasting!
