从影片剪辑（检查主时间轴播放）在AS3

Question

我有这个功能，但是...... 我想 如果主时间打得那么它去帧并播放 和 如果主要时间是（不是播放），所以它进入帧并暂停

这个函数在主时间自定义滑块控件。

谢谢;

sliderLine_mc.addEventListener(MouseEvent.CLICK,snapTO); 

function snapTO(event:MouseEvent) 

{ 
    if (sliderTrack.mouseX > 0 && sliderTrack.mouseX < 320) 
    { 
     sliderKnob.x = mouseX; 
     sliderKnob.x = MovieClip(root).currentFrame * (300/MovieClip(root).totalFrames); 


     if (MovieClip(root).isPlaying == true) 
     { 
      MovieClip(root).gotoAndPlay(Math.floor(mouseX/(300/MovieClip(root).totalFrames))-60); 

     } 
     else if (MovieClip(root).isPlaying == false) 
     { 
      MovieClip(root).gotoAndStop(Math.floor(mouseX/(300/MovieClip(root).totalFrames))-60); 

     } 




    } 
}

您可以创建一个观察者的影片剪辑，将你想要做什么：

public class WatcherMC extends MovieClip 
{ 

private var last_enter_frame:int= 0; 
private var root_animation_steps:int= 0; 
private var root_stoped_steps:int= 0; 
public RootIsPlaying:boolean= false; 
public function WatcherMC():void 
{ 
addEventListener(Event.ENTER_FRAME, onEnterFrame); 
} 


private function onEnterFrame(event:Event):void 
{ 
    if (MovieClip(root).currentFrame!= last_enter_frame) 
    { 

     root_animation_steps++; 
     if (root_animation_steps> 3) 
     { 
        root_stoped_steps= 0; 

        root_is_playing(); 
     } 
    } 
    else 
    { 
      root_stoped_steps++; 

      if (root_stoped_steps> 3) 
      { 
      root_animation_steps= 0; 
      root_is_still_not_playing(); 
      } 
    } 
     last_enter_frame= MovieClip(root).currentFrame; 
} 


private function root_is_playing():void 
{ 
// root is playing, do what ever I want 
RootIsPlaying= true; 
} 
private function root_is_still_not_playing():void 
{ 
// root is not playing, do what ever I want 
RootIsPlaying= false; 
} 

}

把你的代码中的函数root_is_playing和root_is_still_not_playing 就可以检查WatcherMC_instance.RootIsPlaying或者如果你实例化一个WatcherMC电影剪辑的实例..

是这样的：

var WatcherMC_instance:WatcherMC= new WatcherMC(); 
// use WatcherMC_instance.RootIsPlaying .. 

我希望这会有所帮助！
