我收到錯誤XSHIFT，YSHIFT = Manager.movementKeys（個體經營，XSHIFT，YSHIFT）類型錯誤：「NoneType」對象不是可迭代的，當我運行我的代碼和我無法弄清楚爲什麼。我不應該得到任何回報作爲無，並且我的論據都不是無。我對任何縮進錯誤表示歉意。類型錯誤：「NoneType」對象不是可迭代時調用鍵的功能

我甚至沒有從運動的關鍵得到回報。我正在做一些痕跡，當我調用移動功能時，它似乎會出現錯誤。作爲參考，我在每個功能（移動和移動鍵）的頂部放置了一個打印件，並且只有移動鍵中的打印件出現。 –
嘿，這正是我的帖子所說的。您的'movementKeys'功能只有'if'和'elif'。因此，如果沒有按鈕被按下，函數不返回任何東西，這意味着它返回'None'。查看我更新的答案並提供可能的修復方法但請記住，我沒有真正檢查你的遊戲邏輯。 – enpenax
你說得對，我錯過了那個相當大的東西，但感謝你的幫助 –
