If you change your pickMode to USE_BOUNDS, it
will solve the problem. If your geometry
is not line type, either BOUNDS or GEOMETRY
will do the work.
Hope this can help,

> Hi,

> LineArray.COLOR_3| LineArray.NORMALS);
> and I've set this capability
> line.setCapability( LineArray.ALLOW_INTERSECT );
> line.setCapability( LineArray.ALLOW_COORDINATE_WRITE );
> sline = new Shape3D(line);
> sline.setCapability(Shape3D.ENABLE_PICK_REPORTING);
> sline.setCapability(Shape3D.ALLOW_APPEARANCE_READ);
> sline.setCapability(Shape3D.ALLOW_APPEARANCE_WRITE);
> I want to mouse click on the line and change its appearance with the
> method of the class
> PickObject like in the TickTockPicking example.
> PickObject pick = new PickObject(c,r);
> path =
> pick.pickClosest(evt.getX(),evt.getY(),PickObject.USE_GEOMETRY);
> Shape3D shape = (Shape3D)
> pick.pickNode(path,PickObject.SHAPE3D);
> When I pick on the line the value contained in path and shape are always
> null.
