	import laya.utils.Handler;



	public class addPic

	{

		private var picX:int;

		private var picY:int;

		public function addPic(str:String, x:int, y:int)

		{

			picUrl = str;

			picX = x;

			picY = y;

			Laya.loader.load(picUrl, Handler.create(this, showBgImg));

		}

		

		

		private function showBgImg():void

		{

			pic = new Image();

			pic.graphics.drawTexture(Laya.loader.getRes(picUrl), picX, picY);

			

			Laya.stage.addChild(pic);

		}

	}
