Code: 

dynamicsWorld->stepSimulation(1/60.f,10);for (int i=dynamicsWorld->getNumCollisionObjects()-1; i>=0 ;i--){btCollisionObject* obj = dynamicsWorld->getCollisionObjectArray()[i];btRigidBody* body = btRigidBody::upcast(obj);if (body && body->isActive() && body->getMotionState()){btTransform trans;body->getMotionState()->getWorldTransform(trans);btVector3 velocity = body->getLinearVelocity();std::cout<<"vy: "<< velocity.getY()<<std::endl;}}
Is this the best way to iterate over all of the active objects in the dynamicWorld? Also does this mean that I am ultimately iterating over all of the objects twice to see if they are active because the btMotionState checks for active objects and then I check for them?

Thanks for your time,
Dan

I am hoping that I can use the btMotionState because it was so easy to setup, but I don't think that is a possiblility....

Thanks so much for your time,
Dan
