I am having serious trouble trying to develope Artificial Intelligence (AI) for a gokart racing game that I'm making.
Somebody please help me...

Right now, the Martix-Track is higher on the sides than in the middle, the cars move forward at a set pace. When the cars height increases, they turn toward the side that is lower in relation to their present height.

I used the Ground-Tilting code from the tank2 demo to tilt the karts, but They are really glitchy. They go off of the track sometimes, and hit the walls, and when they recover, they sometimes start going backwards.

It depends on the complexity of your game :
In a simple game, you shall get some waypoints on your track (1,2,3,4,...)
When an ennemi Kart is on waypoint 4, it shall be redirected to waypoint 5 and head for it, etc.

Yeah...I thought of that but I started having problems with the karts facing the wrong ways. The track I'm using is just a square for now... I'm not going to use anything Super-complex like on F-Zero for the Game-Cube, so what I need doesn't need to be really complicated.

Facing the wrong way ? You have have to check the position of the next waypoint, then you point the object to that position, then simply MOVE OBJECT.
That's the simplest you could do ... without them getting out of the track.

But...
If I use a "point object" command the Karts just point instantly.
I need to do it with smooth turning...How could I do that?

before the refresh (sync), point the object at the waypoint and get the object angle, then set it back to what it was, then use curvevalue to make it swing around in a smooth curve onto the new heading.

And no more
I've figured it out, Commander!
Limey! This thing had better work!

Thanks!

For anyone whose wondering about my solution:
I just detect for the position of the next check point thing, and figure its position, and the angle the kart would point to face it, then gradually inc/dec the Y-angle of the kart until it faces it. No more tilted tracks for me! YEAH! THE POWER IS MINE!
Thanks to DarkBasicPro!
