为什么一运行就直接退出了 根据您提供的代码，我注意到在主循环中缺少一个终止游戏的条件。在当前的代码中，主循环会一直进行下去，直到窗口关闭才会退出。因此，添加一个用于控制游戏运行状态的变量可以解决这个问题。
您可以尝试在代码中添加以下内容：
running = True
while running:
# 省略部分代码
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False# 当窗口关闭时，将running设置为False
# 省略部分代码
这样，当游戏窗口被关闭时，主循环会结束，从而退出游戏。请尝试修改代码并重新运行，看是否能够解决问题。如果还有其他问题，请随时提问。
如果问题已经解决，请设置最佳答案 这个问题可能是由于程序中的pygame.quit()和sys.exit()导致的。这两行代码会立即退出程序，所以程序运行后会立即退出。
如果您想让程序保持运行状态，您可以将这两行代码注释掉，或者将它们放在一个条件语句中，以便在满足某个条件时才退出程序。例如，可以使用一个标志变量来控制程序是否退出，只有当标志变量为True时才执行退出操作。
另外，您还需要确保您的程序中的文件路径是正确的，比如background.png、sound文件夹中的音频文件以及font.ttf文件。如果这些文件不存在或者文件路径不正确，程序可能会在加载这些文件时出现错误并退出。您可以使用绝对路径或者相对路径来指定这些文件的位置。 有报错信息吗？可以在 Explorer 中的地址栏输入 cmd，在 cmd 中输入 py xxx.py
