1. Salut à vous,

   Ya t-il moyen de détecter une tâche rouge par exemple sur un .SWF contenu dans un autre .SWF ? En faite je voulai rejouer l´animation depuis l´élément qui se trouve imbriqué dans mon produit final.

   Merci d´avance et publier le plus possible de truc intéressants.

   1. For those who do not understand French, Daf’s question was “can we track colors inside an external swf loaded inside a parent swf”. The answer: that’s pretty easy. Here’s how :

      import cc.cote.chromatracker.ChromaTracker;   var ct:ChromaTracker;   // Load the external swf (circle.swf) using a good ol' Loader var loader:Loader = new Loader(); loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onSwfLoaded); loader.load(new URLRequest("circle.swf"));   // Once loaded, convert to MovieClip and add to display list function onSwfLoaded(e:Event):void {   circleSwf = MovieClip(loader.contentLoaderInfo.content); addChildAt(circleSwf, 0); ct = new ChromaTracker(circleSwf, 0xFF0000, 0.4); addEventListener(Event.ENTER_FRAME, onEnterFrame);   }   // Constantly update the tracking function onEnterFrame(e:Event):void {   // Call tracking method var rectangle:Rectangle = ct.track();   // Position and size green rectangle over detected region so we can see the detection zone.x = rectangle.x; zone.y = rectangle.y; zone.width = rectangle.width; zone.height = rectangle.height;   }

      import cc.cote.chromatracker.ChromaTracker; var ct:ChromaTracker; // Load the external swf (circle.swf) using a good ol' Loader var loader:Loader = new Loader(); loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onSwfLoaded); loader.load(new URLRequest("circle.swf")); // Once loaded, convert to MovieClip and add to display list function onSwfLoaded(e:Event):void { circleSwf = MovieClip(loader.contentLoaderInfo.content); addChildAt(circleSwf, 0); ct = new ChromaTracker(circleSwf, 0xFF0000, 0.4); addEventListener(Event.ENTER_FRAME, onEnterFrame); } // Constantly update the tracking function onEnterFrame(e:Event):void { // Call tracking method var rectangle:Rectangle = ct.track(); // Position and size green rectangle over detected region so we can see the detection zone.x = rectangle.x; zone.y = rectangle.y; zone.width = rectangle.width; zone.height = rectangle.height; }

      The key is to convert the loaded swf to a regular MovieClip (highlighted above). Once you have a MovieClip (or any DisplayObject) you can use it with ChromaTracker in the regular fashion.

      Here’s a full Flash CS6 example you can download to try it out.

   1. Unfortunately, without more information, it is hard for me to help you out.

3. I am wondering if this could be adapted to read heart rate data by placing a finger directly onto the camera? I need some help with the as3 code, it would compare one frame colour to the next. This is because every time our hearts beat the colour of the skin changes (becomes more red). Any help would be great. many thanks Tina

   1. Hello Tina. I have no idea but it would be interesting to try… However, honestly, I have pretty much given up on AS3 for quite a few years now. The way Adobe let it die a slow death and gave up on developers like me who invested a lot into Flash/AIR/AS3 left a very sour taste in my mouth. I’m sticking to open technologies now…
