wheel skidding

I'm with a racing sidescroller (still! ^^ ) where a car is a box with two lineJoints and two wheels. I'd like to know when a wheel (whose lineJoint motor is activated) loses traction. I don't mean when the wheel goes airbone, but when the wheel starts skidding. I think that the answer is when the torque is bigger than the force the tyre can apply to the ground, but I don't know how to translate this into farseer.


Thanks a lot!

One way could possibly be to check if there is lateral velocity with respect to the forward direction. Here's a tutorial that might give you some ideas:

Hi Jerry, thanks for your answer,


unfortunately I'm trying a sidescroller (something like supermario but with cars). I don't think the same principle can be applied as a top down car racing game :(

For the record, I just found that the difference or quotient between the wheel AngularVelocity and its LinearVelocity.Length() is approximately what I needed :)
