'score'是我要交叉的变量。 score + 1 每秒发生 80 次，而 MainGame() 为 运行。在游戏已经玩完之后，我想将分数 blit 到 StartScreen()。基本上我想在开场画面上看到球员得分。
您必须在任何方法定义之外对变量 score 进行初始化。要访问变量并对其进行编辑，您可以使用关键字 global。这告诉 python 您要访问的变量不在函数的局部范围内。阅读此处了解有关正确使用全局变量的更多信息。

我不确定我是否捕捉到所有得分实例，但如果我捕捉到了，这应该可行。分数在代码的顶部定义。在您的两种方法中，我都在顶部键入了全局分数。这让函数知道在它的范围之外寻找变量 score 。此外，导入应放在文件的顶部。无需始终如一地导入相同的模块。
您可以做的是将变量完全放在函数外部，而不是将其保留在函数内部。这样，您拥有的所有功能都可以识别它。但是，如果您想从另一个函数编辑 score，只需简单地将单词 global score 放在顶部，表示您想要编辑 score 的全局版本。
使用全局变量就可以了。另一种选择是将分数传递给所有分数更改函数和return（至少）分数。
def some_func (score, otherstuff):
# do something with the inputs.
score += 1
return score, otherstuff.
另一种管理分数的方法是为您的游戏创建一个 class，前提是使 class 的所有分数更改函数成员合理。这可能是一个好的设计，也可能是一个糟糕的设计。如果采用这种方法，__init__ 函数应将 self.score 初始化为零。得分改变函数应该只更新 self-score.

我不确定我是否捕捉到所有得分实例，但如果我捕捉到了，这应该可行。分数在代码的顶部定义。在您的两种方法中，我都在顶部键入了全局分数。这让函数知道在它的范围之外寻找变量 score 。此外，导入应放在文件的顶部。无需始终如一地导入相同的模块。
您可以做的是将变量完全放在函数外部，而不是将其保留在函数内部。这样，您拥有的所有功能都可以识别它。但是，如果您想从另一个函数编辑 score，只需简单地将单词 global score 放在顶部，表示您想要编辑 score 的全局版本。
使用全局变量就可以了。另一种选择是将分数传递给所有分数更改函数和return（至少）分数。
def some_func (score, otherstuff):
# do something with the inputs.
score += 1
return score, otherstuff.
另一种管理分数的方法是为您的游戏创建一个 class，前提是使 class 的所有分数更改函数成员合理。这可能是一个好的设计，也可能是一个糟糕的设计。如果采用这种方法，__init__ 函数应将 self.score 初始化为零。得分改变函数应该只更新 self-score.
