Detailed Description

Implement this class to provide collision filtering. In other words, you can implement this class if you want finer control over contact creation.

Member Function Documentation

bool b2ContactFilter::ShouldCollide ( b2Fixture *  fixtureA, b2Fixture *  fixtureB  )

virtual

Return true if contact calculations should be performed between these two shapes.

Warning

for performance reasons this is only called when the AABBs begin to overlap.

virtual bool b2ContactFilter::ShouldCollide ( b2Fixture *  fixture, b2ParticleSystem *  particleSystem, int32  particleIndex  )

inlinevirtual

Return true if contact calculations should be performed between a fixture and particle. This is only called if the b2_fixtureContactListenerParticle flag is set on the particle.

virtual bool b2ContactFilter::ShouldCollide ( b2ParticleSystem *  particleSystem, int32  particleIndexA, int32  particleIndexB  )

inlinevirtual

Return true if contact calculations should be performed between two particles. This is only called if the b2_particleContactListenerParticle flag is set on the particle.
