I can't solve problem with car behaviours. I have two car - a black and a red cars. A black car has a car behaviour, a red car has GridMovement. Look at this screenshot - <img src="http://i35.tinypic.com/20kt6b5.jpg">.
A black and a red cars have a collision event => a black car to be stopped, a red car should lower its speed to o. My problem is that I can't move back my car after collision. I'm sure there is a way to fix this, but I failed to do it by using standard events and actions.
