Für das Beispiel ist der Flash Player 9 erforderlich - sonst sieht man nichts. Der Quellcode des Beispiels steht unten.

package {
  import flash.display.Sprite;
  import flash.events.Event;
	
  [SWF( backgroundColor='0xcccccc', frameRate='10', width='400', height='400' )]

	public class BasicGraphics extends Sprite
	{
		private var initObj:Object;
		
		public function BasicGraphics()
		{
			this.addEventListener (Event.ENTER_FRAME, signal);
    	}
    	
		public function signal(event:Event):void
		{   
			initObj = new Object();
			initObj.tx=Math.round(Math.random()*380)-30;
			initObj.ty=Math.round(Math.random()*380)-30;
			initObj.twidth=Math.round(Math.random()*256);
			initObj.theight=Math.round(Math.random()*256);
			initObj.tcolor=Math.round(Math.random()*16)*0x111111;

			var rectangle:ObjRectangle=new ObjRectangle(initObj);
			this.addChild(rectangle);
		}
	}	
}	

import flash.display.Shape;

class ObjRectangle extends Shape
{
  public var tx:Number = 0;		
  public var ty:Number = 0;		
  public var twidth:Number = 256;		
  public var theight:Number = 256;		
  public var tcolor:Number = 0;		
	
	public function ObjRectangle(initObj:Object) {
		for(var i:String in initObj) {
      	this[i] = initObj[i];
  	}
		draw();
	}
	
	public function draw():void {
		graphics.beginFill(tcolor);
		graphics.drawRect(tx, ty, twidth, theight);
		graphics.endFill();
	}
}
