   I'm not sure if I'm going about this completely the wrong way or not, but here goes:

   Based off the example for Box2D, I've created a groundBox - four edges that border the screen. This works great, and the player bounces around inside this box exactly as he should.

   What I would like is to have other object pass through the edges without colliding. I've tried adding a filter.groupIndex to the edges, but that seems to crash the app. I'm guessing that b2PolygonShapes that have been setAsEdge can't have a groupIndex defined?

   Is there another way around this?

   I hope this makes sense - thanks in advance :)

   I ran into the same problem, I simply left the border as box.

   I can't help you with box2d because I am still using chipmunk. To accomplish that in chipmunk you have 3-4 options, like groups, layers and finally if you return NO from callback collision function, that object wouldn't make collision. Maybe something similar could be achieved with box2d... Sorry for no better help from me :)
