Question

信息：我目前正在制作一款游戏，想要在开始之前先了解开始菜单，因为这有助于我想要设计的游戏的其他部分。基本上我想要它，所以当我按START GAME游戏开始时，当我按HELP它会显示帮助页面时，当我按QUIT时游戏将退出。到目前为止，当QUIT被按下时游戏退出了，这很简单，但我仍然坚持开始游戏。

问题： 当我按下开始游戏时，它会显示播放器精灵以及时钟。时钟和帧一样有效，直到移动鼠标。

我现在发现了你的问题。问题出在游戏循环中。

while not done:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            done = True

    if menu_on == True:
        **do stuff 1**

    if game_start == True:
        **do stuff 2**

在**做东西1 **你没有检查事件循环中的任何事件，所以它工作正常。但是在**做东西2 **你试图检查一个事件 CLOCKTICK ，你定义为每1000毫秒（每秒）发生一次。

事件变量将仅引用事件循环后的最后一个事件，这意味着如果发生任何事件（例如移动鼠标或按下按钮），它可能会发生检查该事件而不是 CLOCKTICK 。

此外，如果没有事件发生，事件变量将仍然成为上一个事件。这就是为什么你的时钟如此之快，而不是每一秒钟。

解决这个问题的方法是为每个州设置一个事件循环。

while not done: 
    if menu_on == True:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                done = True

        ** the rest of the code **

    if game_start == True:
        menu_on = False
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                done = True
            elif event.type == CLOCKTICK:  # Make sure this code is inside the event loop!
                minute = minute + 1
                if minute == 60:
                    hour = hour + 1
                    minute = 0
                if hour == 24:
                    day = day + 1
                    hour = 0
                if day == 365:
                    year = year + 1
                    day = 0

        ** the rest of the code **

Pygame，如果鼠标移动，游戏将停止
