problem with graphic sprite inside a MovieClip Class

Question

¡Hola!.Hello!.I have a MovieClip "panelMenu" class.Inside the class he drew a rectangle (cap) to use later in an event.What happens is that I do not see the rectangle! No matter how much I put it in one place or another, it can't be seen! This code works perfectly in the action panel, but when passing it to a class I cannot make the rectangle display.addChild does not work and there is no compiler error.   Thanks for the help  package componentes {import flash.display.MovieClip;import flash.events.MouseEvent;import flash.display.Sprite;public class panelMenu extends MovieClip {var tapa:Sprite;public function panelMenu() {tapa = new Sprite();tapa.graphics.beginFill(0x8A9597, 1);tapa.graphics.drawRect(0,0,180,800);tapa.graphics.endFill();tapa.alpha = 0.8;function playMenu (event:MouseEvent):void{if (currentLabel == "uno"){play();addChild(tapa);}}function retryMenu (event:MouseEvent):void{if (currentLabel == "diez"){play();removeChild(tapa);}}addEventListener (MouseEvent.CLICK, playMenu);tapa.addEventListener (MouseEvent.CLICK, retryMenu);}}}

Hi. The panelMenu is a display object because it extends the MovieClip class. So you must add any instance of it to the display list first for it to work as expected. Like this:var pepe:panelMenu = new panelMenu();addChild(pepe); Thanks a lot!

Hi.

It's because you're not adding the sprite instance to the Display List when panelMenu is instantiated. If you don't do this, your click event won't work because your panelMenu don't have any graphic to detect a mouse event.

package componentes
{
	import flash.display.MovieClip;
	import flash.events.MouseEvent;
	import flash.display.Sprite;

	public class panelMenu extends MovieClip
	{
		var tapa:Sprite;

		public function panelMenu()
		{
			tapa = new Sprite();
			tapa.graphics.beginFill(0x8A9597, 1);
			tapa.graphics.drawRect(0, 0, 180, 800);
			tapa.graphics.endFill();
			tapa.alpha = 0.8;
			addChild(tapa);			
			addEventListener(MouseEvent.CLICK, playMenu);
			tapa.addEventListener(MouseEvent.CLICK, retryMenu);
		}
		
		private function playMenu(event:MouseEvent):void
		{
			if (currentLabel == "uno")
			{
				play();
				addChild(tapa);
			}
		}
		
		private function retryMenu(event:MouseEvent):void
		{
			if (currentLabel == "diez")
			{
				play();
				removeChild(tapa);
			}
		}
	}
}

Also, it's a better practice to define your methods outside the constructor.
