Add a b2Filter to b2ParticleSystemDef #82

Closed iainmerrick closed 2 years ago

iainmerrick commented 6 years ago

This filter is applied to all fixtures before checking for collisions with individual particles. This is more efficient than b2_fixtureContactFilterParticle for skipping entire classes of fixture/particle collisions.

I can't remember the details of this and clearly don't need it any more, so I'll just close it :)
