Hello folks,
I'm trying to get an object that's been clicked by the user.
My problem is that it always return null.
here is my code (extract from my Behavior class):
...
SceneGraphPath[] stuffPicked = root.pickAll(getPickRay(x,y));
System.out.println(stuffPicked);
...
}
private PickRay getPickRay(int xpos, int ypos) {
Point3d mousePos = new Point3d();
Vector3d mouseVec=new Vector3d();
Point3d eyePos = new Point3d();
PickRay pickRay=new PickRay();
universe.getCanvas().getCenterEyeInImagePlate(eyePos);
universe.getCanvas().getPixelLocationInImagePlate(xpos,ypos,mousePos);
mouseVec.sub(mousePos, eyePos);
mouseVec.normalize();
pickRay.set(eyePos, mouseVec);
System.out.println(eyePos+","+ mouseVec); // Strange the eyePos keep
changing on each run
return pickRay;
}//End getPickRay
What am I doing wrong?
Regards,
Chris.
