Simple Multi-Touch Demo

I know this won't mean much right now since there's only a couple developers who can actually see/use it, but this is basically how it's working right now.

The current limitation on this script is that you can only drag one light at a time. So for instance if you move two fingers around only one of the lights will move.

PHP Code:

//#CLIENTSIDE



function GraalControl.onMouseDown(keymod, mx, my, clicks, mouse) {

  with (findimg(200 + mouse)) {

    x = mx - 64;

    y = my - 64;

    image = "light2.png";

    alpha = 0.99;

    zoom  = 1.4;

    layer = 4;

    //I had a mod equation here, but the forums didn't like it.

    //temp.lightcolor = mouse [percent] 4;

    temp.lightcolor = mouse;

    switch (temp.lightcolor) {

      case 0: red = 1; blue = green = 0; break;

      case 1: blue = 1; green = red = 0; break;

      case 2: green = 1; blue = red = 0; break;

      case 3: red = green = 1; blue = 0; break;

    }

  } 

}



function GraalControl.onMouseDragged(keymod, mx, my, clicks, mouse) {

  with (findimg(200 + mouse)) {

    x = mx - 64;

    y = my - 64;

  } 

}



function GraalControl.onMouseUp(keymod, mx, my, clicks, mouse) {

  hideimg(200 + mouse);

}

Anyway here's an image just to show what happens when you're touching it with four different fingers.

Thanks for posting this, this is v. interesting

Technically speaking, you don't just need an iPhone/iPod to use multi-touch. Macbooks have had em for awhile (ew) and now Windows 7 supports it so I imagine there are some PCs that have it out there as well, so this is a good time for this kind of thing to be understood. :)

The client probably doesn't have an interface to communicate with the Windows 7 or Macbook support.

Thanks for posting this. May turn out to be pretty helpful to me.

MacBooks have multi-touch trackpad support. In other words, you can't have two "mice" like you can on an iPhone. The only use for multi-touch on a MacBook right now is gestures (and they work quite well).
