# Intersecting dynamic bodies Box2D/Libgdx

Is that normal that while I'm jumping (by a player represented with a circle) on a dynamic bodies (boxes) they are interecting? It seems that there is some kind of diffraction. Is that any way to reduce this? Restitution is set to 0 for all.

And the moment after a collison

A little overlap is to be expectedone with Box2D, try increasing the positionIterations parameter in the call to World.step (also consider experimenting with the velocityIterations parameter).
You can also try stepping the World in smaller increments, Gaffer on Games's Fix Your Timestep has a good description on how to decouple the physics time from the render time.
