Mute / UnMute Sound AS3

Posted in AS3 on January 13th, 2010 by admin – 3 Comments

If you need to mute/unmute a sound in a MovieClips timeline (eg. if you have a player that loads external swfs)
Try using SoundMixer and soundTransform like this:

1
2
3
4
5
6
7
8

import flash.media.SoundTransform;
import flash.media.SoundMixer;
 
// Mute - sets volume to 0
SoundMixer.soundTransform = new SoundTransform(0);
 
//UnMute - sets volume to 1 (100%)
SoundMixer.soundTransform = new SoundTransform(1);

Of course there are other ways to do it but this was exactly what I needed for my project and it worked just fine.
Feel free to comment other ways to do it.

Cheers!

AS3 lightBox class

This is not ready but I would like to share it anyways, for two reasons: I couldn’t find a free class (or didn’t look hard enough) and someone else might be looking for it. And also so people can take a look at my code and point something that could be improved.

I will post the final version once it is ready.

			var req:URLRequest = new URLRequest(url);
			_loader = new Loader();
			_loader.contentLoaderInfo.addEventListener(Event.COMPLETE, onComplete, false, 0, true);
			_loader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, handleProgress, false, 0, true);
			_loader.load(req);
		}
 
		//---------------------------------------

		public function alignToCenter(object:DisplayObject):void
		{
			object.x = (object.stage.stageWidth - object.width) / 2;
			object.y = (object.stage.stageHeight - object.height) / 2;
		}
 
		//---------------------------------------
		// PRIVATE METHODS
		//---------------------------------------
		private function handleProgress(event:ProgressEvent):void
		{
			var percent:uint = int((event.bytesLoaded / event.bytesTotal) * 100);
			trace(percent);
		}
 
		private function onComplete(event:Event):void
		{
			_loader.contentLoaderInfo.removeEventListener(Event.COMPLETE, onComplete);
			handleImage();
		}
 
		private function handleImage():void
		{
			/* create holder for the bitmap */
			_imageHolder = new Sprite();
			addChild(_imageHolder);
			_imageHolder.addChild(_loader);
 
			/* align object */
			alignToCenter(_imageHolder);
		}
	}
}

in order to use it just create a new Instance of it:

var lightBox:LightBox = new LightBox("assets/imgs/retratos/img-001.jpg");
addChild(lightBox);

I am working on the background and a loader and I will post as soon as they are done and integrated.
