My Car object often freezes or stalls. I have it fall from above a terrain (which is also used in a StaticPhysicsObject). I can run the car in the air, and it doesn't freeze on the terrain untill I stop controlling it, but once I do it is unable to move. I have the same issue when running jmextest.physics.vehicle.CarTest… It doesn't freeze right away, but after a few seconds it does, and I am unable to move it.
I'm using the newest source (I updated from the the CVS today)
After some playing around with my car, it seems that this freezing is related to wheel size and the smoothness (# of polygons making up) of the wheel… when I use larger wheels this problem does not occure.
Seems like an odd solution, but it's worked so far.
