The rocket launcher has no sensors to detect position or movement. There are some rough ways to estimate and track that I am experimenting with. However I also noted that I have two Wiimotes, and since the Wiimote has motion sensors that can detect axis in three dimensions, why not try the other Wiimote? It works perfectly well. I am still experimenting with the code a bit.
So my first reaction was...Hmmm...I wonder if you could get these guys working with the XBOX 360? Wouldn't it be cool if whenever you got whacked in HALO 3, it shot a rocket at you? Or even better, if you could shoot one at your buddy ("must...resist..urge to buy more toys")?
