How to make Non Colliding bodies in Box2D ?

Hi,

For making non colliding bodies in Box2D, you may need to give SAME, NEGATIVE, group index to the b2FixtureDef of bodies you created. See the following code.

fixtureDefA.filter.groupIndex = -7;
fixtureDefB.filter.groupIndex = -7;

The bodies with the above two fixture definitions won’t collide.
