2DFPhysics

2D Fixed-Point Physics for usage in Unity.

Currently built on Unity 2019.2.8f1, but can work on lower versions.

Goals

1. Deterministic. Should get the same result on all platforms.
2. Supports rollback. Should be able to save/restore anything having to do with the simulation and have it play back the exact same.

Other Details

• The project uses my fork of FixedPointy to handle all the fixed point math, I'd appreciate any contributions there also.
