Actionscript 3 每4秒支付一次随机电影3

我有5个MovieClips（5个简单的按钮），我需要他们从第二帧开始，每4秒钟播放一个。我做错了什么？谢谢

var clipArray:Array = new Array();



clipArray[0] = loader.button_01_mc.gotoAndPlay (2);
clipArray[1] = loader.button_02_mc.gotoAndPlay (2);
clipArray[2] = loader.button_03_mc.gotoAndPlay (2);
clipArray[3] = loader.button_04_mc.gotoAndPlay (2);
clipArray[4] = loader.button_05_mc.gotoAndPlay (2);




var clipTimer:Timer = new Timer(4000);
clipTimer.addEventListener(TimerEvent.TIMER, playClips);



function playClips(event:TimerEvent):void
{
    //Chooses a random clip in your array

     var randomClip:int = Math.random() * clipArray.length;

}



clipTimer.start();

您需要在该数组中存储对movieclips的引用，而不是gotoAndPlay方法调用的结果（该结果为空）。然后使用随机索引从数组中获取一个片段，并对其调用gotoAndPlay方法

var clipArray:Array = new Array();
clipArray[0] = loader.button_01_mc;
clipArray[1] = loader.button_02_mc;
clipArray[2] = loader.button_03_mc;
clipArray[3] = loader.button_04_mc;
clipArray[4] = loader.button_05_mc;

var clipTimer:Timer = new Timer(4000);
clipTimer.addEventListener(TimerEvent.TIMER, playClips);

function playClips(event:TimerEvent):void {
  var randomClip:int = Math.floor(Math.random() * clipArray.length);
  var mc:MovieClip = clipArray[randomClip];
  mc.gotoAndPlay(2);
}

clipTimer.start();

那可能会很贵
