We actually subclasses the wand behaviour, but I've left in the relevant config file lines for the basic usage. The likely culprit for a work device interface but no interaction is either not attaching the behaviour to the ViewPlatform (see the end of this message), or not assigning ButtonActions in the WandViewBehavior. Good luck! I'm happy to see other people building ConfiguredUniverse apps, it makes our lives so much easier!

Hi all, i'm trying to use the WandViewBehavior in a ConfiguredUniverse application. I wrote a Java interface for "trackd" that is working great, I get all the sensor and button values correctly from the wand, the only problem i'm having is controlling (rotating, scaling, translating) objects in a "ConfiguredUniverse" using the WandViewBehavior. I'm using a configuration file to setup the wand behavior and i can see and move the wand around in virtual space. But like i said, i can't manipulate objects in the world using the wand. Thanks a lot for any info u can provide. Ahmed
