okay i asked ealier the best racecar a.i. and decided to use waypoints
http://www22.brinkster.com/iceduck/gokart2.blend
now i have it so when waypoint property is at 1 it tracks to waypoint 1 then on near it’s spossed to add waypoint property +1 but the near isn’t registering? help?
never mind i did it using messages from the empty to the racer. oh the link now has the racers working (still in developement so the 3 racer doesn’t go all the way around) anybody can use anything and it’s a pretty neat way for racecar a.i.
great, glad it works ok 
i may even get round to actually making a racing game myself someday… 
cheers
