I have finally managed to get together the source files for the Motion Detection script. The script allows you to control an interface simply by waving your hands in the air infront of a camera. This is pretty cool if you want to add some extra interactivity to your site. The original post can be found here. This original code was taken from Web Designer Mag. They hold all the copyrights etc

The code is below, I wish I had more time to go through it fully and comment it out but I don’t. If you need any help, add a comment to this post.

import flash.display.*;

import flash.geom.*;

var cam:Camera = Camera.get();

sizeX = cam.width;

sizeY = cam.height;

cam.setMode(544,396,25);

vid.attachVideo(cam);

vid._width = cam.width;

vid._height = cam.height;

mov_pos_array = new Array(“0″, “0″, “-544″, “-1088″, “-1632″);

newX = 0;

Xspeed = 0;

content_mc.onEnterFrame = function() {

Xspeed = ((this._x-newX)/2+Xspeed)/5;

this._x -= Xspeed;

};

active = false;

aCount = 0;

start_btn.onPress = function() {

active = true;

start_btn._visible = false;

start_btn.enabled = false;

};

now = new BitmapData(160, 120);

before = new BitmapData(160, 120);

rect = new Rectangle(0, 0, 160, 120);

pt = new Point(0, 0);

sizeDif = 160/cam.width;

thisFrame1=0;

thisFrame2=0;

thisFrame3=0;

thisFrame4=0;

over1=false;

over2=false;

over3=false;

over4=false;

onEnterFrame = function () {

if (!cam.muted && active == true) {

now.draw(vid);

now.draw(before,new Matrix(),new ColorTransform(),’difference’);

now.threshold(now,rect,pt,’>’,0xff111111,0xffffffff);

before.draw(vid);

for (i=1; i<5; i++) {

_root["ballNew"+i+"Y"] = (_root["impact"+i]._y/cam.height)*120;

_root["ballNew"+i+"X"] = _root["impact"+i]._width/2+_root["impact"+i]._x;

_root["ballNew"+i+"X"] = 160-(_root["ballNew"+i+"X"]*sizeDif);

_root["val"+i] = now.getPixel(_root["ballNew"+i+"X"], _root["ballNew"+i+"Y"]);

if (_root["val"+i]>16700000) {

_root["thisFrame"+i] +=1;

_root["over"+i]=true;

}

if (_root["thisFrame"+i] == 2){

_root["impact"+i]._alpha = 40;

newX = mov_pos_array[i];

_root["thisFrame"+i] = 0;

_root["over"+i]=false;

} else {

_root["impact"+i]._alpha = 100;

}

}

rotated = Xspeed/4;

disk_mc._rotation+=rotated;

}

};

checkglitch = function(){

for (i=1; i<5; i++) {

if (_root["over"+i]==true){

_root["thisFrame"+i] = 0;

_root["over"+i] = false;

}

}

};

inter = setInterval(this, “checkglitch”, 1200);

Finally, what you have been waiting for: the source code.

Here is a PDF of the tutorial. Sorry for the low image quality. Hope it helps
