Question

我一直在尝试使用不同的影片剪辑在Flash中创建一个库。

Timeline
-back button
-next button
-stop button
-play button 
-Main Movie
 (these are inside Main Movie)
 --Animation 1
 --Animation 2
 --Animation 3

我在主电影中设置了动画，实例名称和帧名称如“动画1”。我让它玩和停止，但我无法通过后面和下一个按钮来回穿过每个动画。什么是正确的方法，我可以把它拉下来？

我得到了它的工作，但有一个小虫子。每当我点击下一个或后退按钮时，它会转到第一个帧名称，然后转到另一个帧名称。我做了一个跟踪，我发现它计为“ad-1，ad-2，ad-3等......”或“ad1，ad2，ad3等......”

var currentAnimationIndex:int;
var currentAnimation:int;
var animeOstart:Number = 1;
var animeOend:Number = 3;

function playAnimation(frameIndex:int):void 
{ 
   var frameName:String = "ad" + frameIndex.toString();
   trace(frameName)
   ads.gotoAndPlay(frameName);
   ads.movie.gotoAndPlay(1);

   currentAnimationIndex = frameIndex; 
} 

function playBack(event:MouseEvent):void 
{ 
   --currentAnimationIndex; 

   if(currentAnimationIndex < animeOstart) 
      currentAnimation == 1; 

  playAnimation(currentAnimationIndex); 
} 

function playNext(event:MouseEvent):void 
{ 
   ++currentAnimationIndex; 

   if(currentAnimationIndex > animeOend) 
      currentAnimation == 3; 

  playAnimation(currentAnimationIndex); 
}

您应将以下代码放在按钮所在的主时间轴上。我已将实例名称“main”指定给您的Main MovieClip。

  var currentAnimationIndex:int;

  public function playAnimation(frameIndex:int):void
  {
       var frameName:String = "Animation " + frameIndex.toString();
       main.gotoAndStop(frameName);

       currentAnimationIndex = frameIndex;
  }

  public function playBack(event:MouseEvent):void
  {
       --currentAnimationIndex;

       if(currentAnimationIndex < 1)
          currentAnimation == 3;

      playAnimation(currentAnimationIndex);
  }

  public function playNext(event:MouseEvent):void
  {
       ++currentAnimationIndex;

       if(currentAnimationIndex > 3)
          currentAnimation == 1;

      playAnimation(currentAnimationIndex);
  }

创建一个变量，用于注册当前动画并递减它或增加它以返回或播放下一个动画。使用MouseEvent侦听器将相关功能分配给按钮。我在这里用过1＆amp; 3你可以有几个变量，minAnimIndex＆amp; maxAnimIndex。

希望这有帮助！

在AS3中找到了如何做到这一点!!!!

b_back.addEventListener(MouseEvent.CLICK, prevSection);
b_next.addEventListener(MouseEvent.CLICK, nextSection);

function nextSection(event:MouseEvent):void {

    var thisLabel:String = ads.currentLabel; // gets current frame label as string
    var thisLabelNum:String = thisLabel.replace("ad", ""); // cuts the leading letters off of the number
    var curNumber:Number = Number(thisLabelNum); // converts that string number to a real number
    if (curNumber < 3) {
        var nextNum:Number = curNumber + 1; // adds 1 to the number so we can go to next frame label
        ads.gotoAndPlay("ad" + nextNum); // This allows us to go to the next frame label
    }else if(curNumber >= 3){
        ads.gotoAndPlay("ad" + 1); // This allows us to go to the next frame label
    }
}

function prevSection(event:MouseEvent):void {

    var thisLabel:String = ads.currentLabel; // gets current frame label as string
    var thisLabelNum:String = thisLabel.replace("ad", ""); // cuts the leading letters off of the number
    var curNumber:Number = Number(thisLabelNum); // converts that string number to a real number
    var prevNum:Number = curNumber - 1; // subtracts 1 from the number so we can go to next frame label
    ads.gotoAndPlay("ad" + prevNum); // This allows us to go to the previous frame label*/
    if (curNumber == 1) {
        ads.gotoAndPlay("ad" + 3); // This allows us to go to the next frame label
    }

}
