Well...
Yes, it would be cool if it worked like that, but no, it probably won't, and instead incorporate a "do a swishy motion to use force power" instead of freeform lightsabre swinging. ;(
But still damn cool.
Not to be outdone by Sony's rumbling DualShock 3 controller, LucasArts has confirmed that a Star Wars game based around use of a Light Sabre is on its way to the Wii. The game will be a reincarnation of one already discussed for existing platforms, but will spur gamers to use the Wii’s controller as a Light Sabre. LucasArts …
"The concept of a Light Sabre for the Wii was first penned in December 2006, when the MacSaber’s developer, Isnoop, announced the WiiSaber – no explanation needed"
Really? Are you sure it wasn't first penned by, umm, EVERYBODY, which was the number of people thinking exactly the same thing the moment that the pointing/motion sensing ability of the Wii was revealed? I know I did, I just didn't care enough to write an app that makes swishy sounds when I wave my Wiimote around (wow, exciting...MacSaber was lame too).
...as with other wii games, the "window" of movement will be about 6 inches cubed. If you move the remote too fast, it won't be recognised, eventually leading to what most people do when they use the wii remote for a while - sit down, and jiggle it slightly to get the best results. Strangely, I can't remember Obi Wan et al doing that in the films...
Er, what?
There is no "Window of movement". The motion sensors are accelerometers, they detect acceleration of the control on 3 axes. Obviously, if you wang it about as fast as you can you will end-stop the accelerometers straight away and find it does appear to have a restricted range.
The ADXL330 accelerometers used in the Wiimote have an effective range of +/- 3g, so it doesn't take much to end-stop them.
If, however, you use smooth movements you will find the response more realistic.
So more Obi-Wanesque smooth moves and less frantic wasp-swatting is what is needed.....
