Get collision for

Hi

Is it possible to get the force of a contact, collision and then let the colliding object pass through?

All pass trough options are working on preCollision events, but event.force is working on postCollision.

Main player in my app is made out of several physics bodies. They are connected with joints. And I would like to know, when the joints are overstretched at on moment so I can apply an action.

Thank you all for the help…
