Elastic collisions and a frictionless environment

Questions & Answers

We are setting up a small game which is something similar to

https://play.google.com/store/apps/details?id=com.entwicklerx.dodgetheseballsfree.

So far, we have the balls moving in random directions and bouncing off the walls and colliding with each other. The collisions look fine but the problem that we are facing is that the balls slow down over time till they completely stop moving.

The rigid bodies have “Drag” and “Angular Drag” set to 0.
The balls (also the walls) have the this material attached, where the dynamic friction and static friction are set to 0.

I’m not sure what is causing this behavior. Any idea what I might be doing wrong ?

I’m having a similar problem with my game, it’s an asteroids like game so it supposed to be in frictionless space, you have to create a physics material with 0 friction and apply it to your objects, this worked for me except for one type of collision, which is making me think it may be a unity bug
