People...I am not looking for a work around. The point is, that a phsyics engine should be able to handle thouse basics!!!
I dont think the problem is down to C2.
Its YOUR sprite that is causing the problem!
If they were all the same size, I dont think it would happen.
You have an idle animation that that is touching the floor, then you change to a walk animation that has different sizes, so the collision's change.
Maybe one of the C2 veterans can correct me if I'm wrong.
