我和几个朋友创建了一个篮球游戏，用户可以从中选择不同的游戏模式。我负责主菜单，必须将所有游戏链接在一起。这是一组四个任务。我通过导入文件并在用户单击按钮时将用户发送到该文件来链接它的方式。它适用于我的另外两个朋友，但是一个朋友的模块仅在单击按钮时更改标题。
我的主菜单代码：

# Set the height and width of the screen
size = [800, 600 ]
screen = pygame.display.set_mode(size)
pygame.display.set_caption("Basketball")
# Loop until the user clicks the close button.
done = False

if __name__ == '__main__':
main()
答案 0 :(得分：2)
我认为发生这种情况是因为其他模块在main函数中没有主循环，但在全局范围内，并且缺少此if子句：
if __name__ == '__main__':
main()
这意味着其他游戏/模块在您导入时将运行（通常是不希望的）。要使用main函数开始游戏，您必须调用它：
def start_maxgame():
import maxgame
maxgame.main()
顺便说一句，模块将被分配给与您的函数同名的局部变量，这有点令人困惑。我建议重命名功能。
