如何重新開始遊戲？（tkinter）

Question

我正在與tkinter進行遊戲，玩家必須躲避酸雨。 我差不多完成了它，我只是需要一種在按下Up鍵後重新啓動整個遊戲的方法。我已經做了一個雨後擊中玩家的功能。這個函數檢查一個事件是否按下了向上鍵，並觸發比重新啓動遊戲的代碼的重新啓動功能。所有內部的遊戲類。 下面的代碼：

預先感謝您！

Answer 1

您可以從主循環方法中刪除while 1並使用布爾值來保持循環。當按下UP鍵和玩家被雨淋時，您可以將布爾值切換爲false。

然後，你可以這樣做：

while 1 : 
    g = Game() 
    g.mainloop() 

和你的遊戲循環，直到永遠。
