Moving the stage in AS3?

programming flash
1

Hey guys,

So I’ve been trying to move the stage’s X and Y position and keep on getting this error:

Error: Error #2071: The Stage class does not implement this property or method.
	at Error$/throwError()
	at flash.display::Stage/set y()
	at Main/scroll()

I am using a document class, here it is:

package 
{
	import flash.display.MovieClip;
	import flash.events.Event;
	import flash.events.MouseEvent;
	
	public class Main extends MovieClip
	{
		private var WIDTH:Number;
		private var HEIGHT:Number;
		private const PERCENT:Number = 0.05;
		private const SCROLL_X:Number = 5;
		private const SCROLL_Y:Number = 5;
		
		public function Main()
		{
			WIDTH = stage.stageWidth;
			HEIGHT = stage.stageHeight;
			
			this.addEventListener(Event.ENTER_FRAME, scroll, false, 0, true);
		}
		
		public function scroll(e:Event)
		{
			if (stage.mouseX > (WIDTH - (WIDTH * PERCENT)) )
				stage.x -= SCROLL_X;
			else if (stage.mouseX < (WIDTH * PERCENT) )
				stage.x += SCROLL_X;
			
			if (stage.mouseY > (HEIGHT - (HEIGHT * PERCENT)) )
				stage.y -= SCROLL_Y;
			else if (stage.mouseY < (HEIGHT * PERCENT) )
				stage.y += SCROLL_Y;
		}
	}
	
}

As for why I’m trying to move the stage, I have a movieclip which moves according to keyboard input and i want the stage/Background to always center on him.

Any ideas how to fix this?

Thanks
