AS3 Z-INDEXING電影短片

Question

各位好，你好 我有舞臺上有2個movieclip實例名稱：綠色&橙色。 我使用這個代碼，以時間軸幀1〜提出每個項目點：

MovieClip.prototype.bringForward = function():void{ 
    var currentDepth = this.parent.getChildIndex(this); 
    if(currentDepth<this.parent.numChildren-1){ 
     this.parent.setChildIndex(this, currentDepth+1); 
    } 
} 


green.addEventListener(MouseEvent.MOUSE_UP, clicked); 
orange.addEventListener(MouseEvent.MOUSE_UP, clicked); 

function clicked(e:MouseEvent){ 
    e.target.bringForward(); 
} 

誰能告訴我如何從一個外部文件。如在此加載此：

package { 


    public class Main { 



     public function Main() { 

     } 



    } 

} 

我嘗試了很多次，但我沒有任何運氣。

我嘗試這樣：

package { 

    import flash.display.Sprite; 
    import flash.events.MouseEvent; 
    import flash.accessibility.AccessibilityProperties; 
    import flash.display.Bitmap; 
    import flash.display.DisplayObject; 
    import flash.display.DisplayObjectContainer; 
    import flash.display.MovieClip; 
    import flash.display.Stage; 
    import flash.events.Event; 
    import flash.events.EventDispatcher; 
    import flash.events.KeyboardEvent; 

    public class Main { 




     public function Main() { 


      addListeners(); 




     } 



MovieClip.prototype.bringForward = private final function():void{ 
    var currentDepth = this.parent.getChildIndex(this); 
    if(currentDepth<this.parent.numChildren-1){ 
     this.parent.setChildIndex(this, currentDepth+1); 
    } 
} 




     private final function addListeners():void 
     { 

      green.addEventListener(MouseEvent.MOUSE_UP, clicked); 
      orange.addEventListener(MouseEvent.MOUSE_UP, clicked); 

     } 





    private final function clicked(e:MouseEvent) 
    { 
    e.target.bringForward(); 
    } 





    } 

}

不要使用原型的東西。做這樣的功能類如下：

private function bringForward(clip:DisplayObject):void{ 
    var currentDepth:int = getChildIndex(clip); 
    ... rest of your swapping logic 
} 

private function clicked(event:MouseEvent){ 
    bringForward(event.target as DisplayObject); 
}
