How do I use pysics with solids ?

Hi guys, from what I understand phiscs and solids should not be mixed.

I made my platform become inmovable as phisic...but my player car that has pinned several sprites on it, has a strange behavior.

My need:

I have a car that drives on platforms...but there are a few barrells that I like to push realisticly if my car hits the barrells...what do U guys suggest ? I like some simple sollution if that is possible:)

thanks

What is the strange behaviour you are talking about?

Actually using pin and physics could give unexpected behaviours as well, why not use joints for those are the physics equivalent of pinning..

Oh ok, I did not know about joints... the behavior is that the player is shaking madly arround :/

I give a look to the joints...

thanks
