ActionScript 3鼠标移动事件不发送

Question

脚本问题是，每个movieclip调度向下和向上鼠标事件，但鼠标移动事件不是由某些影片剪辑调度，这是一个意外的行为，而我跟踪了down事件，并且它成功跟踪每个对象

也建议您对我的代码的反馈，谢谢。

private function loadPurchasedClip(){ 
      var decorationItem:String; 
      var lastItemIndex:uint = this.getChildIndex(tree1); 
      var item:Sprite; 

      for(var a in purchasedItems){ 

       for(var b in purchasedItems[a]){ 

       if(purchasedItems[a][b].item=='shed'){ 
        item = new shed(); 
       } else { 

        var ClassDefinition:Class = loadedDecorationItem.purchaseItem(purchasedItems[a][b].item) as Class; 


        item = new ClassDefinition(); 

       } 
       item.x = purchasedItems[a][b].posX; 
       item.y = purchasedItems[a][b].posY; 


       item.addEventListener(MouseEvent.MOUSE_DOWN,function(e:MouseEvent){ 
         Mouse.cursor = "hand"; 
         e.target.startDrag(false); 

         dusbin.visible = true; 
        item.addEventListener(MouseEvent.MOUSE_MOVE,trashMe); 
       }); 

       item.addEventListener(MouseEvent.MOUSE_UP,function(e:MouseEvent){ 

        Mouse.cursor = "auto"; 
        e.target.stopDrag(); 
        externalPhpCall(e); 
        dusbin.visible = false; 
        if(trashClip){ 
         removeChild(trashClip); 
         trashClip = null; 
        } 
       }); 
       item.mouseChildren = false; 


       // if item is fence or flowers then move them behind the tree 
       if(
        String(purchasedItems[a][b].item).indexOf('fence')!=-1 
        || 
        String(purchasedItems[a][b].item).indexOf('flower')!=-1 
       ){ 
        addChildAt(item,lastItemIndex); 

        lastItemIndex++; 
       } else { 
        addChildAt(item,this.numChildren-2); 
       } 

       purchasedNameAr[getChildIndex(item)] = purchasedItems[a][b].item; 

      } 

     }

     var lastItemIndex:uint = this.getChildIndex(tree1); 
     var item:Sprite; 
     var Move:Boolean

不能肯定，但我认为它可能是你期待的剪辑继续派遣MouseEvent.MOUSE_MOVE事件甚至一度鼠标已经离开夹 - 这不会发生，只有当本地鼠标指针坐标（即yourClip.mouseX/mouseY）与剪辑本身的图形相交时，它才会触发 - 即使在拖动剪辑时，也不能保证它将分派MOVE事件。

我们假设你的剪辑都在根目录，这意味着你有机会获得 '舞台' - 你可以这样做：

取代：

item.addEventListener(MouseEvent.MOUSE_MOVE,mouseMove); 

有：

stage.addEventListener(MouseEvent.MOUSE_MOVE,mouseMove); 

...但您应该记得在必要时删除该事件（如果鼠标未在剪辑上释放，请再次使用舞台）：

stage.addEventListener(MouseEvent.MOUSE_UP,endMove); 


//Don't use anon function as won't have stage reference: 

function endMove(e:MouseEvent):void { 
     //The rest of your code, then: 
     stage.removeEventListener(MouseEvent.MOUSE_MOVE,mouseMove); 
    }
