Racing AI

Hi, my group for a midterm project decided that we were going to create a racing game. I am in charge of putting everything together in torque and making sure it all runs smoothly. The only problem is, that I have no idea how to make computer "cars" race with me. I know that I need to set up a path with marker, but I am not sure how to implement it into the CS file for the computers. Any help on this would be great by either responding here or emailing me at the_matty2004@hotmail.com
