Привет, можешь просто расширить функционал обычного спрайта вот так:

public class MySprite extends Sprite
	{
		private var _pivotX:Number;
		private var _pivotY:Number;
		private var _x:Number;
		private var _y:Number;
 
		public function MySprite() 
		{
			_x = 0;
			_y = 0;
			_pivotX = 0.5;
			_pivotY = 0.5;
		}
 
		public function get pivotX():Number
		{
			return _pivotX;
		}
 
		public function set pivotX(value:Number):void 
		{
			_pivotX = value;
			super.x = _x - width * _pivotX;
		}
 
		public function get pivotY():Number
		{
			return _pivotY;
		}
 
		public function set pivotY(value:Number):void 
		{
			_pivotY = value;
			super.y = _y - height * _pivotY;
		}
 
		override public function get x():Number 
		{
			return _x;
		}
 
		override public function set x(value:Number):void 
		{
			_x = value;
			super.x = _x - width * _pivotX;
		}
 
		override public function get y():Number 
		{
			return _y;
		}
 
		override public function set y(value:Number):void 
		{
			_y = value;
			super.y = _y - height * _pivotY;
		}
 
		override public function set width(value:Number):void 
		{
			super.x = _x - value * _pivotX;
			super.width = value;
		}
 
		override public function set height(value:Number):void 
		{
			super.y = _y - value * _pivotY;
			super.height = value;
		}
	}
