How to make a wheel turn

[dsengere]

How can I make a wheel (tire) turn if and only if object (marble) is touching an object (floor)

I have absolutely no knowledge of thyme. Could someone please walk me through it in a step-by-step manner? THANK YOU.

Well.. you could use some variables to change a motor speed...
so..
1.press the ~ key
2. type in: "Scene.my.eng1 = 15.0"
3.Make your tire/engine
4. Go to the script menu of the tire hinge and where it says "Motor spped" Change the variable in it to: "{Scene.my.eng1}"
5.Make a collider of some sorts
6.go to the script menu of the collider
7.Where it say "Oncollide" Put this in: "{Scene.my.eng1 = 0.0;scene.my.15.0}"

(note take out all quotations...)

I think you allready asked this in another post.. and I already gave you the ansver?
Might be im wrong though..
Also you could use CCW value false / true.. If you want it to turn other way
