Python Pygame在添加了一点代码后突然落后了，但为什么呢？
我有一个用Pygame制作的游戏，我添加了一个“小”更新，当按下空格键时，一个精灵会变成另一个精灵80毫秒，这会使整个游戏滞后（不仅仅是按下空格键，而是一直）。有人能帮忙吗？：） 以下是“更新”之前的一些代码： 男人Python Pygame在添加了一点代码后突然落后了，但为什么呢？,python,pygame,lag,pygame-clock,pygame-tick,Python,Pygame,Lag,Pygame Clock,Pygame Tick,我有一个用Pygame制作的游戏，我添加了一个“小”更新，当按下空格键时，一个精灵会变成另一个精灵80毫秒，这会使整个游戏滞后（不仅仅是按下空格键，而是一直）。有人能帮忙吗？：） 以下是“更新”之前的一些代码： 男人 class Man(Sprite): def __init__(self, ai_settings, screen): super().__init__() self.screen = screen # Load the i

clock.tick（60）您需要每帧调用一次
clock.tick（60）时钟。勾选（60）clock。打勾（60）
