This is a Cinema4D R8.1 project file containing XPresso/Coffee code for calculating
the position and orientation of a car over time with input controls for speed
and steering. It's a bit rough in places but it works. Most of the work is
actually done in Coffee. If you are an R6 or R7 owner then the Coffee file
can be read here. It won't work as-is in R6 or R7, but you can see what the code does. This project file requires Cinema4D 8.1. It will not work with 8.0.
The XPresso 'bouncing ball' project in the R8 tutorial manual has a bug.
This file shows two alternative approaches to this project, neither of which
have this bug.
