how to move car and wheel with scripting in 3d max

I se that tutorials in youtube i send you that link can you help what is that script he used http://www.youtube.com/watch?v=_CvyxcMlZgg

Hes not really using a script, hes using expression controllers and wired params.

I don’t think he is using script. As per my experience he is using expression controller that is more accurate resultant. It can be used for “crescendos” & “decrescendos” throughout the performance of the music. If you want to move car wheel with scripting in 3D max then you can follow complete tutorial illustrated at autodesk.com.
