I am studying this constraint and wondered if this is a good option. My only concern is if it is added to the car chassis, how will the slider constraint act as a shock based on its sliding velocities vrs. the cars mass. The cars mass may not impact it at all, but if anyone knows this, I would appreciate your thoughts.

Thanks

I found an easier solution, Marco added the 6th parameter in phcon_setparams2 to be like a shock absorber:
phcon_setparams2(frw_id,vector(-30,30,0),nullvector,vector(80000,200,0));

I found this setting to be nice and bouncy.

Thanks Marco

A PH_WHEEL basically is a PH_SLIDER with a secondary axis. As raiden pointed out you can adjust the bounciness for PH_WHEELs. You could also add another PH_SLIDER on top of it, but then things might get way too elastic.

While this sounds exactly what I am trying to do, I can't seem to avoid the wheels falling of my car! Do you have to reposition the wheel via vec_set every frame or is the wheel position meant to be given by the contraint?

I have a car chasis with standard box physics. 4 bones where the suspension system would meet the wheel, which I am using for position of each wheel as well as suspension animation.

So any advice or example code on setting up a wheel and axle would be really helpful to me, as my wheels just drop off. Thanks and sorry for hijacking the thread.

So I opened the plCar01.wdl and figured it out, sorry
