[WiiFlash] The Wiimote z-Depth?

[Patrick Matte | BLITZ]

Well it's just the distance between the 2 points... the points x and y values are from 0 to 1. So if one point is exactly in the middle of the screen, it's x is 0.5, and the other point could be at 0.75. so you have a distance of 0.25 in the x axis. Do the same for the y axis.

And the formula to get the distance between two points is Math.sqrt((x*x)+(y*y));
But the formula is conveniently available in the point class as a static method. flash.geom.Point.distance(point1,point2);

OK -thanks! So what does:

var distance:Number =
flash.geom.Point.distance(wiimote.ir.point1,wiimote.ir.point2);

...really tell you? That's the distance of what?
