我对pygame很新，并且设计一个处理不同游戏屏幕的主循环时遇到问题。我正在用3种不同的屏幕编写一个跳棋游戏。
简介屏幕：获取所需的电路板尺寸N并将其传递到主循环。然后主循环调用game_screen，调用我的游戏类，调用N作为参数。
游戏画面：调用游戏类，所以整个游戏都在这里运行。它还可以从游戏类中获得经过时间和赢家等回报。我们的想法是将它们传递到主循环中，并将它们作为参数调用game_over_screen。
这导致问题，因为我的回归＆＃34;选择＆＃34;有时是一个元组，有时是一个int。当我关闭窗口时它是一个int，但是当赢得游戏时会返回一个元组。
游戏结束：基本上只需要获胜者和经过的时间并打印出来。单击按钮时也应返回选项。这应该回到介绍屏幕。
我需要帮助： 我的主循环中的逻辑看起来非常笨重。有时返回int，有时候是元组的想法对我来说似乎并不合适。我很感激有关如何设计这类简单游戏的主要循环的任何提示。

答案 0 :(得分：0)
解决此问题的一种方法是返回包含信息的字典。 添加“原因”，您可以根据需要存储该原因，以存储游戏结束的原因（取消，游戏结束）和其他条目。
这还将使您以后可以返回其他信息，同时仍返回相同的数据类型。
