how to push away two objects that are touching each other

Hello, how to push away two objects that are touching each other ?

I simulate a roll of the dice with physics, but sometimes he touches himself when he doesn't move anymore, I would like to push them away, and I don't want one die to be on top of another, I don't know how to do that.

In real life, I would have liked to do this in 3D, but we can't do it with C3 :(

I'd like to do a dice poker game.

I'm not sure if this will work, I can't open the file. But you can try this > if object 1 is overlapping object 2 then have one of the objects move forward a few pixels.
