Cocos2d - Is is possible to turn off collision for a Box2d b2Body with a b2FixtureDef?

Question

I have a b2Body with a b2FixtureDef. I'd like to be able to turn off the ability of the b2Body to collide. Is this possible?

Answer 1

Yes it is possible. Make it sensor.

    b2FixtureDef fd;
    fd.isSensor = true;
    body->CreateFixture(&fd);

Also with filter(fd.filter) you can specify collision specific to body.
