I wanted to signal a bug with the AmmoJS plugin ( perhaps? ) or just physics in general. I have noticed this while trying to switch my game https://gcapsarena.com ( does not work on chrome now) to the latest version of babylonjs ( I have to since I get an webgl error on chrome).
GCaps is a ball game, I have developed it in 4.0.0.alpha.21 and it worked great. When migrating to the latest version I notice that the ball never stops movement even after setting velocities to 0 or calling forceUpdate on the Impostor. Since GCaps is a multiplayer game you realize that is almost hell to make deterministic. I do not seem to find a solution for this. Luckily, I think I have it reproduced here :
If you open the console, you will see that even after calling forceUpdate the spheres position is always changing. forceUpdate resets the impostor so logically it should also reset the forces, something not right.
