i totally followed the tutorials open the physics setting and activate physics, changed to the kinematic state, but it doesnt work at all. its annoying, why?? who can help me?:hehe:

A little more context would help us to figure it out. is your "kinematic" object attached to an avatar? That kind of info.....:)

what do u mean by it? you can see my attachment, it seems totally attach a object.

OK, I see now.

The car looks to be set just fine. Make sure that the obstacles (spheres) are set to "dynamic". Kinematics are not effected by other kinematics. You will also need a physics floor or infinite plain. Otherwise your dynamic objects will just fall off screen, as there is nothing to stop them.

Good luck. Ask again if it doesn't work.

thank you very much. it has been sorted out!! :P
