玩过一次游戏后，如果我从主菜单中再次选择它，它会立即切换到屏幕上的游戏（pygame）

Question

基本上每当我从主菜单中选择我的游戏，它就会玩，但如果我回到主菜单，再选择一次，它只是在屏幕上显示游戏，不会再玩了。你知道吗

在下面的代码中，它是关于第一次运行后不运行的主菜单的zy\u mainloop（）部分的。我真的很感谢你的帮助

def main_menu():
    WIDTH = 1280
    HEIGHT = 800
    screen = pygame.display.set_mode((WIDTH, HEIGHT))

    main_menu = True

        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
            elif event.type == pygame.KEYDOWN:

                    HEIGHT = 600
                    pygame.display.set_mode((WIDTH, HEIGHT))

我似乎没有代码做多个窗口，这取决于pygame.退出事件，然后调用pygame.display.set\模式以前也是。你知道吗

可能“QUIT”事件在函数调用中持续存在？ 我建议您在每个pygame.display.set_mode调用前面加上一个pygame.event.get()-以清除挂起的事件，并确保队列中没有来自上一个屏幕的事件。你知道吗

回顾您的代码—调用game_over_noscore()如何使程序退出主循环？或者它没有，并且只在播放器关闭窗口之前一直显示东西？你知道吗
