Use behaviour class to capture mouse motion

Question

Hi,
I am trying to write a behavior class for mouse by extending the behavior class. But it does not seem to capture the mouse movement when I move the mouse. Here is my code. Plz help me to find out the problem.
import java.awt.event.*;
import java.util.Enumeration;
import javax.media.j3d.MouseBehavior;
import javax.media.j3d.TransformGroup;
import javax.media.j3d.Transform3D;
import javax.media.j3d.WakeupOnAWTEvent;
import javax.media.j3d.WakeupCriterion;
import javax.media.j3d.WakeupCondition;
import javax.media.j3d.WakeupOr;
import java.awt.AWTEvent;
public class UserEyeBehavior extends MouseBehavior {
private TransformGroup sutg;
private ViewerCoordinates vc;
private float x=0;
private float y=0;
private float z=0;
/** Creates a new instance of UserEyeBehavior */
public UserEyeBehavior(TransformGroup sutg,ViewerCoordinates vc) {
this.sutg = sutg;
this.vc = vc;
private void setEvent()
WakeupCriterion[] criteria = new WakeupCriterion[2];
criteria[0] = new WakeupOnAWTEvent(MouseEvent.MOUSE_DRAGGED);
criteria[0] = new WakeupOnAWTEvent(MouseEvent.MOUSE_MOVED);
WakeupCondition condition = new WakeupOr(criteria);
this.wakeupOn(condition);
public void initialize()
System.out.println("in");
setEvent();
public void processStimulus(Enumeration criteria){
WakeupCondition condition;
AWTEvent[] events;
System.out.println("ahgghgfasdhg");
while(criteria.hasMoreElements())
System.out.println(2);
condition = (WakeupCondition)criteria.nextElement();
events = ((WakeupOnAWTEvent)condition).getAWTEvent();
for(int i=0;i<events.length;i++)
System.out.println(3);
if(events.getID() == MouseEvent.MOUSE_DRAGGED)
System.out.println(((MouseEvent)events[i]).getX()+" "+((MouseEvent)events[i]).getY());
else
System.out.println(((MouseEvent)events[i]).getX()+" "+((MouseEvent)events[i]).getY());
setEvent();
Main program section
//Add navigation in universe
UserEyeBehavior ueb = new UserEyeBehavior(su.getViewingPlatform().getViewPlatformTransform(),vc);
bg.addChild(ueb);

Answer 1

replace setEvent() call
by
wakeupOn(mouseCriterion);
