Hi,
I�m have a potential bug report when using the pickAny() method.
When my scene is drawn, at one point I engage a Behavior that goes to
an object within the scene and attempts to find out which other objects
are in its �line of sight�. I do this by finding a point on the surface
of the shape and a vector in the sight direction which is encapsulated
(with other info) into a user defined LightBeam object. The behavior
then calls the shootBeam method below to find the other shapes in its
vicinity.
public void shootBeam(LightBeam beam) {
Object pickedObject = new Object();
PickRay nextPick = new PickRay(beam.startPoint, beam.direction);
SceneGraphPath pickPath = new SceneGraphPath();
sceneObjectsBranchRoot.pickAny(nextPick);
pickedObject = pickPath.getObject();
if(pickedObject != null)
System.out.println("Obj = " + pickedObject.toString());
} //end shootBeam()
The program compiled successfully and ran, but never found any
intercepted objects. However, when the fourth line is changed to:
pickPath = sceneObjectsBranchRoot.pickAny(nextPick);
it will indeed find the intercepts. The question is, why did it compile
and run correctly if no provision was originally made for accepting the
returned value from pickAny()?
Thanks - Gary Graf
(Actually, this e-mail started out as a question as to why it wasn�t
working and as is often the case, while typing it I saw the problem).
