Make cannon-es deterministic

[johnnyrainbow]

Currently the main issue I have with cannon-es/js is that is it non deterministic in real time, this is quite a major thing for a physics engine to have, would love to see it implemented.

cannon is basically in maintenance mode.

Hey @johnnyrainbow!

Folks at pmndrs are keeping the lights on, but yes currently there are no developers actively working on improving cannon-es.

WASM physics libraries such as rapier.js and JoltPhysics.js are worth considering for sure. The biggest downside to these WASM port libraries over cannon is bundle size.

If there are things you're keen to see change in cannon-es you will probably need to contribute changes yourself. I note that you've got a fork of cannon-es with some activity, if there are changes that make sense to be upstreamed we can review PRs.
