thanks tompo.. that script works very well and is flexible too.. it worked excellent with a level where i had used Newton for the car..

In another one where i had used ent_move for movement and normal.x etc for tilt and roll, the camera was panning and tilting too fast, but adjusting the values 0.1 0.4 etc made it better.. again it shows only the butt while turning, but its way better than what i was using.

thanks for the help
