Find out if a wheel is skidding?

Hey peeps... a simple one... Ive had it sussed before with hard coded values but its not good enough anymore.

I have the velocities of the wheel in local/global directions, the radius of the wheel, and "rotation speed" of the wheel.

What i need to know, is if wheelspin is occuring. (and preferably by how much)


IM gessing its pretty simple and i *should* know it, but im not able to think too well this morning :)

angularvelocityofthewheel = carspeed / wheelradius
so
IF (angularvelocityofthewheel * wheelradius) <> carspeed THEN wheelspin = TRUE

Hmmm... thats what i've got..... I must be doing something wrong...

At least i know the forula is right. I'll look into it some more. Thanks WolRon :)

umm... okay, i was typing the formula worong. muhaha

i thought the above, but typed:

if (Wheelspeed=carspeed*angvelofwheel)<>carvel.


Problem solved... and an entire function of 50 lines replaced by one with 5. :)
