When I played around with FP2 it was easy to check if there wasn't anything anymore colliding with a fixture. But now that FP3 is using CCD I don't now how to check that. I know that I can turn that of but it's there for a reason.
I'm using OnCollision and OnSeperation delegates.
I tried to make a list and add the fixtures that collides with my characters groundSensor, but the same fixture can be added more than once. And if I check if the the fixture is already in the list the performance goes bad.
Probably an easy fix for this problem.
