我认为您的问题在于如何使用datetime来控制何时下移块

您应该查看pygame.time模块。我建议您创建一个变量(例如wanted_fps),其中包含一个整数,表示您希望无止境循环每秒运行的频率。 然后,您的代码应该如下所示:

wanted_fps = 1 # how often I want the endless loop to run per second
fpsHandler = pygame.time.Clock() # fpsHandler created to handle fps

while(True): # our endless loop
    # do something awesome
    fpsHandler.tick(wanted_fps) # makes sure fps isn't higher than wanted_fps
您可以在此处阅读pygame.time的相关内容:

此外,如果您想要一个似乎没有事件处理延迟,您可以将wanted_fps设置为60,然后使用某种计数器变量(例如mycounter)来处理希望事件发生的频率。假设你在无尽的循环中做了这样的事情:

# handle events
if mycounter > 0:
    mycounter -= 1
else:
    # do something amazing
    mycounter = 30

你每秒做60/30=2次令人惊奇的事情,但你每秒处理事件60次,因此你似乎可以立即响应事件。

因为你通过向startTime添加1来设置stopTime,当startTime变为59时,stopTime将变为大于60的值。startTime然后返回到0,因为这是新的一分钟,您被卡住了。index=1,startTime永远不会大于stopTime。if或elif语句的计算结果都不是True。如果你的目标是在重新绘制盒子之前加入一个延迟,考虑一下这样做……/P>
pauseLength = 120
然后在游戏循环中

pygame.time.delay(pauseLength)

这也将允许您加快游戏速度,以增加以后的难度。

尝试从命令行运行它,如果需要毫秒,则查看是否出现任何错误,而不是
startTime=str(datetime.now())
内置
pygame.time.get\u ticks()
如果您的解决方案不是使用延迟函数,我会投票支持这个答案。不阻止事件处理的东西会更好。@Haz您知道一种方法不会阻止事件处理,并且仍然可以在绘制之间提供准确的时间增量吗?同样对于这样一场比赛,我不确定在平局之间我是否会处理多个事件。例如,一个块在屏幕上用一个绘图旋转两个位置。我会跟踪自砖块上次向下移动以来的帧数,并在该帧数超过设定值时更新其位置(最有可能基于所需的帧率),然后重置通过的帧数。在我玩过的大多数俄罗斯方块实现中,你可以水平移动一块砖块,即使砖块是垂直悬挂的。但在达到滴答值之前,pygame会执行延迟。是一样的。这是我的观点。据我所知,在设置任何帧速率时,都没有处理事件的方法。块向下移动是否与帧速率有关并不重要。块的垂直移动不需要人为限制帧速率。通过这样做,你限制了水平移动,潜在的音频播放,以及游戏中基于一个物体的移动而进行的任何其他事情。非常感谢!这解决了我的问题与随机停止和使用fps将更容易调整的难度。
