類型錯誤：錯誤＃1009無法找到空對象

-1

我得到這個真的很煩錯誤「類型錯誤：錯誤＃1009：在monke2_fla無法訪問空對象引用的屬性或方法 :: MainTimeline/UPDATE2（）」我找不到NULL var，除了＃1009錯誤之外，任何幫助都會很棒，因爲腳本工作正常。類型錯誤：錯誤＃1009無法找到空對象

這還不夠遠。不幸的是，這是時間軸編碼的缺陷。這可能是因爲您的任何數量的影片剪輯/顯示對象或兒童未正確設置。確保你的實例名稱是正確的。檢查你的父/子層次結構，確保像「Bunch.parent」這樣的東西實際上有一個父對象。添加跟蹤語句以確定在拋出錯誤之前運行的最後一件事情。 –

好，靠近你的代碼的底部，你說：Bunch.parent.removeChild(Bunch);

但是你也有：Banana_mc1.addEventListener(Event.ENTER_FRAME, moveDown);它調用一個函數，保持引用Bun ch。

您可以通過不刪除束來測試。如果修復了null var問題，那麼你將不得不決定如何繼續。你想讓遊戲繼續或結束後束消失？

再就是也是這個：

hitAry[i].parent.removeChild(hitAry[i]); 
    trace(hitAry[i]);

你試圖跟蹤它，你刪除它之後！那 mightmake hitAry [i] null！

這不會使'hitAry [i]'無效，但是如果'hitAry'中的某個元素沒有添加到stage（或剛剛從其父元素中移除），則其「parent」屬性爲null。這很可能是OP的錯誤，儘管碰到'Bunch'可能會產生相同的結果。 – Vesper
