Hey, thanks for reply. I'm making android game, that's why I'm trying to avoid creating new objects at runtime.
That's inside my contact listener (executed after contact with player)
final Fixture x1 = contact.getFixtureA();
if (contact between my player's head fixture and box)
x1.getBody().getFixtureList().get(0).getFilterData().maskBits = 0x0001;
// and so on to set rest of shorts
But really I can't get how to set those shorts, to make body not collide able with anything (even with the same body type, and that's my main problem now)
// Edit1: I'm stupid, so I will create at beginning Filer object with my bits and than just will set this filter
Filter f = new Filter();
But still the problem is how to set those shorts, to prevent from collision with anything (Even same type bodies)
// Edit2: That configuration works if anyone will need it:
boxBreakFilter = new Filter();
boxBreakFilter.categoryBits = 1;
boxBreakFilter.groupIndex = 2;
boxBreakFilter.maskBits = (short)0;
And than just set this filter on your fixture, and it isn't colliding with anything, even with same body types.
Thanks for help - problem SOLVED.
