Cylinder wheels question

[NaN]

If you have seen it rotate with steering angle you should also have seen it move with suspension .

Push the wheel cylinders into your compound collision shape object first. This way you know that the first 4 shapes are the wheels. Update their position relative to compound shape each time you update your wheels.

My original idea has been to get rid of wheel rays by using wheel contact data, but more for performance reasons. Just make sure that the wheels are always in contact, let them sink into surface by 3-4 cm or so. The problem has been the normals reported by bullet, if I remember correctly. It didn't handle mesh edges very well.

I'd say give it a try. Maybe it'll work better for you.
