I've recently started implementing physics in my game. I'm using the java port of the bullet physics engine. I'm trying to interact with rigid bodies in my scene using rayTest() to select what rigid body to interact with. I'm confused on the correct way of using the rayTest(start, end, callback) function. From my callback I can retrieve a CollisionBody but I need a RigidBody. I'm wondering If I'm about the this the wrong way. Thanks.
