如果有條件地將其簡化成一個循環（沒有拋出錯誤）

Question

這裏我們開始吧！我創建了一個拖放遊戲（足夠簡單），只有在提交按鈕被擊中後才能識別錯誤的棋子。我原本以爲這可以通過使用數組和一個檢查它們的for循環來完成，但每當我這樣做時，它都不會將數據存儲到拖動的剪輯中，因此它們都顯示爲「錯誤」。從那以後，我創造了一個漫長的條件，否則，如果，老實說，感覺笨重，但完美的作品。有什麼想法嗎？

你也許可以縮短到了這樣的循環：

for (var i:int=0; i < dragArray.length; i++){ 
    if (currentClip == dragArray[i]){ 
     if (currentClip.hitTestObject(matchArray[i])) { 
      dragArray[i].removeEventListener(MouseEvent.MOUSE_DOWN, item_onMouseDown); 
      dragArray[i].Boolean = false; 
     } else { 
      dragArray[i].Boolean = true; 
     } 
    } 
}
