单击MC1并等待MC2命中特定帧

Question

我有MC1，当点击时，我想让它等待，这样当MC2命中第50或100帧时，它就会开始播放。两者都有各自独立的时间线。有什么帮助吗？

Answer 1

addFrameScript可以让你在电影剪辑帧中添加和删除代码。

function onMc1Click(e:MouseEvent):void
{
  //targetFrame:int = 50  declared in class..
  mc2instance.addFrameScript(targetFrame, mc2TargetFrameReached);
  mc2instance.play();
}

function mc2TargetFrameReached():void
{
  //call with null function value to remove 
  mc2instance.addFrameScript(targetFrame,null);

  //do other stuff
}

Answer 2

mc1.addEventListener(MouseEvent.CLICK, onMc1Click);

function onMc1Click(e:MouseEvent):void
{
  mc2.addEventListener(Event.ENTER_FRAME, onFrameMc2);
  mc2.play();
}

function onFrameMc2(e:Event):void
{
  if(mc2.currentFrame == 50 || mc2.currentFrame == 100)
  {
    mc2.removeEventListener(Event.ENTER_FRAME, onFrameMc2);
    mc1.play();
  }
}
