How did u do that with the motors? nice car 8/10 for short track and too slow sometimes

Well, i created a custom variable called scene.my.forward = 1.5 wich means, if i put that on a hinge, in the speed bit VIA the script menu, that motor will turn at 15RPM's now i got anoth block, and put scene.my.forward = 6.0 in the onCollide section, that means that if something collides with that box, scene.my.forward will equal 6.0 (in other terms, the wheel will turn at 50RPM's)

For all those people that actualyl do know time, sorry about saying it so simply, but its obvious he does not know anything about it, i just wanted him to have a chance to get it working for HIM
