AS3: Stopping All Timeline Animations

Marc — Thu, 05 Feb 2009 19:41:29 +0000

I haven't posted in months for good reason. I've been involved in a pretty large project at Almighty that led to many late nights. All in all though, the end product turned out to be pretty awesome. I'll post something more on it later. Until then, I hope to roll out some snippets of code that I found useful during the project.

The following snippet of code is a recursive loop that halts all timeline-based animations (assuming they're on a gotoAndStop() loop. This came in handy when working with animation designers.

function haltAllAnimations( mc:MovieClip = null ):void
{
    if( !mc ) mc = this as MovieClip;
 
    for(var i:int = 0; i < mc.numChildren ; i++)
    {
         if( (mc.getChildAt( i ) is MovieClip) == false ) continue;
 
        MovieClip( mc.getChildAt( i ) ).stop();
        if( mc.numChildren > 0 )
            haltAllAnimations( MovieClip( mc.getChildAt( i ) ) );
    }
}

Duplicate a DisplayObject as a BitMap

In working on a project, I created a simple utility class that has this public static method. This basically takes a DisplayObject, copies it, and adds it to a new Sprite which is then returned to the caller. Simple enough. I'm sure this can be refined or done a different way, so have at it.

public static function duplicateImageAsSprite( original:DisplayObject ):Sprite
{
    var bitmapData:BitmapData = new BitmapData( original.width , original.height ,
        true , 0x000000 );
    bitmapData.draw( original as IBitmapDrawable );

    var bitmap:Bitmap = new Bitmap( bitmapData );

    var returnSprite:Sprite = new Sprite();
    returnSprite.addChild( bitmap as DisplayObject );

    return returnSprite;
}

The Obligatory Snippets Post

Marc — Mon, 03 Dec 2007 16:04:24 +0000

There are a bunch of code snippets that I always forget. In an attempt to organize my life, I'm going to throw them up here. Hopefully Matt will too.

Removing all Children From a DisplayList

 
while( numChildren > 0 )
{
	removeChildAt( 0 );
}

Make Sure Everything is on the Whole Pixel

This is just a useful concept to throw out there, since everything should be on the whole pixel if you'd like it to look crisp.

 
override public function set x( value:Number ):void
{
	super.x = Math.round( value );
}

Pretty easy huh? Just do the same for width/height and y.
