More than one object bouncing off each other

I’m making a game where I need something like the DVD screensaver (an object that bounces in an enclosed space) but with more than one object. I have not been able to make it so that when the blocks collide, they bounce in opposite directions. I am using the Bounce extension.

Hello @TomDev. And thus, what is your question ?

Edit : Oups, I did not read correctly : You can’t make both objects bounce as you want.
Maybe could you use the Physics2 behaviour, with gravity scale = 0 (it won’t fall), friction = 0 (it won’t slow down) and restitution = 1 (no momentum will be lost when bouncing)
