Looping as3 animation

programming flash
1

I’m interested in adding a loop to some falling leaves, so a group of leaves fall, there’s a delay and then another group of leaves fall, and then this will repeat.

Any help would be much appreciated!

Here’s the code I have at the moment:

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

public class Main extends MovieClip
{
	private var clips_array:Array;
	
	private const SPRING:Number=.1;
	
	private var timer:Timer;
	
	public function Main()
	{
		init();
		initTimer();
	}
	
	private function init():void
	{
		stage.frameRate=22;
		
		clips_array=new Array(mc_clip_0,mc_clip_1,mc_clip_2,mc_clip_3,mc_clip_4,mc_clip_5);
	}
	
	private function initTimer():void
	{
		timer=new Timer(700,0);
		timer.addEventListener(TimerEvent.TIMER,go);
		timer.start();
	}
	
	private function go(evt:TimerEvent):void
	{
		var n:Number=Math.floor(Math.random()*clips_array.length);
		var clip:MovieClip=new clips_array[n];
		
		clip.x=Math.random()*600/*stage.stageWidth;*/
		clip.y=-clip.height;
		clip.center=clip.x;
		clip.vel_x=2+Math.random()*10;
		clip.vel_y=clip.vel_x;
		clip.angle=0;
		addChild(clip);
		
		clip.addEventListener(Event.ENTER_FRAME,goDown);
	}
	
	private function goDown(evt:Event):void
	{
		var acc_x:Number=(evt.target.center-evt.target.x)*SPRING;
		evt.target.vel_x+=acc_x;
		evt.target.x+=evt.target.vel_x;
		evt.target.y+=15-evt.target.vel_y;
		evt.target.rotation++;
		var sine:Number=Math.sin(evt.target.angle);
		evt.target.scaleX=sine;
		evt.target.angle+=.1;
		if(evt.target.y>=stage.stageHeight+100)
		{
			evt.target.removeEventListener(Event.ENTER_FRAME,goDown);
			var m:MovieClip=evt.target as MovieClip;
			removeChild(m);
		}
	}
}

}
