Picking, but why didn't it work?

Troubleshooting General Help

hi,



I try to pick some geometry, but it didn't work, nothing is picked. Can anyone tell me why?



The method should test where the camera is looking at and just return the name of this Geometry.


public String getLookAt(Camera cam){
      String res="";
      Ray ray=new Ray(cam.getLocation(), cam.getDirection());
      PickResults pr=new BoundingPickResults();
      all.findPick(ray, pr);
      System.out.print(pr.getNumber());  //prints 0 ever
      for(int i=0;pr.getNumber()>i;i++){
         Geometry geom=pr.getPickData(i).getTargetMesh();
         String name=geom.getName();
         System.out.println("n: "+name); //never done
         res=name;
      }
      return res;
   }



I invoke updateCollisionTree() on all Objects which are in the node "all", but I think this doesn't matter cause it use the Object bounds when i do it like this, don't it? It doesn't work when I change it to triangle picking also.
All the geometry in my Node are Boxes.

Thanks for help,
campino

Did you set up the model bounds for the boxes you are trying to pick?
