In this case, we accelerate the cannon ball forward.public void shootCannonBall() { Geometry ballGeo = new Geometry("cannon ball", ballMesh); ballGeo.setMaterial(stoneMat); ballGeo.setLocalTranslation(cam.getLocation()); rootNode.attachChild(ballGeo); ballPhy = new RigidBodyControl(5f); ballPhy.setCcdSweptSphereRadius(.1f); ...
