I'm trying to get car physics to work, and problem is this:
- I create rectangle (car base plate) and I'll attach 2 wheels to it (CreateRevoluteJoint) -> works ok.
- Then I create car main chassis and attach base plate to it with 2 CreatePrismaticJoint (to get nice suspension for car)

However chassis and wheels collide to each other and I would like them no to collide so wheels could freely move up/down.. any idea how to let all parts to collide with the world but not each other (chassis and wheels..)

Yes, just use setSpriteGroup using the same negative group number for all the sprites you don't want to collide with each other.

When you create a joint there is also an option to not let the two connected objects collide by setting 'collide connected' to zero.


this.mess = abs(sin(times#))
