Hi,
Collision can be detected simply using the following lines of code with box2D.
if((contact.fixtureA == aimFixture && contact.fixtureB == tarFixture) || (contact.fixtureA == tarFixture&& contact.fixtureB == aimFixture )) { NSLog(@"Collision between aim fixture and target fixture detected!"); } |
Here aimFixture & tarFixture are two custom fixtures whose collision you want to find out.
