[SOLVED] Limit Camera up and down movement

[JDC]

Have a look at this quick solution:

Several First-Person camera pitfalls (speed and angle) [jME3]

As for the second one the only simple way I found to solve the problem was doing the following: public void simpleUpdate(float tpf) { if(cam.getUp().y < 0) { cam.lookAtDirection( new Vector3f(0,cam.getDirection().y,0),new Vector3f(cam.getUp().x,0, cam.getUp().z)); } } Once again I don’t know how efficient this is.
