Hi! i'm new here and this is my first message

This is my first steps in Java3d (and in 3d at all) and i have a problem... I want the mouse to be used to look around, like in a shooter. My code is being executed, but nothing happens on th screen. There's something i must have misunderstood.

   }
       
   public void processStimulus(Enumeration criteria)
   {
      AWTEvent events[]=mouseEvent.getAWTEvent();
      rot.setIdentity();
      TG.getTransform(rotation);
      evt = (MouseEvent)events[0];
               
                //Formule bidon, juste pour avoir un r├ęsultat quelconque
      rot.rotX(Math.toRadians(evt.getXOnScreen()-500)/200);
                rot.rotY(Math.toRadians(evt.getYOnScreen()-500)/200);
               
                try{
                    rr.mouseMove(500, 500);
                }catch(Exception e){

                }
               
      rotation.mul(rot);
      TG.setTransform(rotation);
     
      this.wakeupOn(mouseEvent);
   }
    }


Otherwise, the keyboard works:

There's actually an easier way built right into the API called OrbitBehavior. An example of how to use it is listed below.

private void orbitControls(Canvas3D c)
   {
      OrbitBehavior orbit = new OrbitBehavior(c, OrbitBehavior.REVERSE_ALL);
      orbit.setSchedulingBounds(bounds);
      ViewingPlatform vp = simpleUniverse.getViewingPlatform();
      vp.setViewPlatformBehavior(orbit);
   }
