ActionScript 3鼠標移動事件不發送

Question

腳本問題是，每個movieclip調度向下和向上鼠標事件，但鼠標移動事件不是由某些影片剪輯調度，這是一個意外的行爲，而我跟蹤了down事件，並且它成功跟蹤每個對象

也建議您對我的代碼的反饋，謝謝。

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，但我認爲它可能是你期待的剪輯繼續派遣MouseEvent.MOUSE_MOVE事件甚至一度鼠標已經離開夾 - 這不會發生，只有當本地鼠標指針座標（即yourClip.mouseX/mouseY）與剪輯本身的圖形相交時，它纔會觸發 - 即使在拖動剪輯時，也不能保證它將分派MOVE事件。

我們假設你的剪輯都在根目錄，這意味着你有機會獲得 '舞臺' - 你可以這樣做：

取代：

item.addEventListener(MouseEvent.MOUSE_MOVE,mouseMove); 

有：

stage.addEventListener(MouseEvent.MOUSE_MOVE,mouseMove); 

...但您應該記得在必要時刪除該事件（如果鼠標未在剪輯上釋放，請再次使用舞臺）：

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); 
    }
