Quick question: Anyone know how to query if a btRigidBody object is already in btDynamicsWorld?
You can call btCollisionObject::getWorldArrayIndex() on the body and check its value.
btCollisionWorld::addCollisionObject() will call btCollisionObject::setWorldArrayIndex(N) on the body, where N is a non-negative index.
btCollisionWorld::removeCollisionObject() will call btCollisionObject::setWorldArrayIndex(-1) on the body.
