For the game im building im using the waypoint system U and Yann shared on the forum.
I modified allot since i have it and the behaviour has become rather unpredictable "in a good way" as it is also my goal to achieve a more realistic feel to the Ai driving.
One part was done in the targets themselves and the other part in the cars behaviour.
As a basics the game im building uses the car behaviour for Ai control, and the cars have gears and other things.
If u would like to take a look at it, u can do that Here
If u are interested in the Capx just let me know <img src="smileys/smiley20.gif" border="0" align="middle">
Thanx for sharing the waypoint system as it is really something!
Im looking forward to your top down racer!
