There are two shapes in my scene. Both of them are loaded by using Lw3dLoader class.(They are lws models) user can move,rotate and zoom by picking on one of them. When two shapes are intersected, I want to write a message to the screen. I write a code similar the example that is given demo TickTockCollision, but it is not work. When mouseEvents[0] = new WakeupOnCollisionEntry(nesne, WakeupOnCollisionEntry.USE_BOUNDS); The canvas3D is seen but it is not work
when mouseEvents[0] = new WakeupOnCollisionEntry(nesne, WakeupOnCollisionEntry.USE_GEOMETRY); The canvas is not seen(all canvas is gray)
"nesne" is a BranchGroup (sahne.getSceneGroup()) or a shape
BranchGroup branch = sahne.getSceneGroup();
for (Enumeration e = branch.getAllChildren(); e.hasMoreElements(); ) {
Object obj = e.nextElement(); if (obj != null && (obj instanceof TransformGroup)) {
TransformGroup tg = (TransformGroup)obj;
for (Enumeration ee = tg.getAllChildren();ee.hasMoreElements();) {
Object newObj = ee.nextElement(); if (newObj != null && (newObj instanceof Shape3D)) {
Shape3D shape = (Shape3D) newObj;
CarpismaYakala cy = new CarpismaYakala(shape);
cy.setSchedulingBounds(new BoundingSphere(new
Point3d(0.0,0.0,0.0), 100.0));
anaGrup.addChild(cy);
}
}
}
}
"CarpimaYakala"public class CarpismaYakala extends Behavior{
private WakeupCriterion[] mouseEvents;
private WakeupOr mouseCriterion;
private Shape3D nesne; public CarpismaYakala(Shape3D nesne){
System.out.println("constructor");
this.nesne = nesne;
} public void initialize(){
mouseEvents = new WakeupCriterion[2];
mouseEvents[0] = new WakeupOnCollisionEntry(nesne,
WakeupOnCollisionEntry.USE_GEOMETRY);
mouseEvents[1] = new WakeupOnCollisionExit(nesne,
WakeupOnCollisionExit.USE_GEOMETRY);mouseCriterion = new WakeupOr(mouseEvents); wakeupOn (mouseCriterion); }
public void processStimulus(Enumeration criteria){
WakeupCriterion wakeup;
System.out.println("buradayim"); while (criteria.hasMoreElements()) {
wakeup = (WakeupCriterion) criteria.nextElement(); if (wakeup instanceof WakeupOnCollisionEntry) {
System.out.println("enter");
}
else if (wakeup instanceof WakeupOnCollisionExit){
System.out.println("exit");
}
}
wakeupOn (mouseCriterion);
}}
What is the problem?any help is appreciated..
