Help with delay in between spawning

programming flash
1

Hi, I’m pretty new to Flash and I’m working on making a tower defense game and I am trying to set a delay between each “minion” as it spawns but with my current code each minion is being deleted when the other is spawned.

Here is my code:

package
{

import flash.display.MovieClip;
import flash.events.Event;
import flash.utils.Timer;
import flash.events.TimerEvent;






public class Source extends MovieClip
{


	var minion:Array;
	public var delay:Timer = new Timer(1000);




	public function Source()
	{


		addEventListener(Event.ENTER_FRAME, loop);


		minion = new Array  ;
	}
	function loop(e:Event)
	{




		if (numChildren<20)
		{
			var m = new Minion  ;
					
				


			delay.addEventListener(TimerEvent.TIMER, spawnDelay);
			delay.start();




			function spawnDelay(event:TimerEvent)
			{


			addChild(m);


			m.x = -40;
			m.y = 300;




			


			}


		}




	}


}

}
