我怎样才能阻止这个计时器造成的滞后？
How could I stop the lag made by this timer?
我一直在做一个 Pygame 项目，最近我在屏幕上显示的程序中添加了一个计时器。该程序主要生成 2 个随机数，并将它们显示在屏幕上。然后，用户可以将结果放在输入框上。如果正确，则“Puntuació”（与分数相同）加 5 分。在我添加计时器之前，一切都运行良好且流畅。现在这段代码仍然有效并且没有崩溃，但它运行得非常慢。我确定它一定与计时器部分有关，但不知道如何解决。

您想每秒减少计时器。因此，定时器时间必须是 1 秒（1000 毫秒）而不是 60 秒（参见pygame.time.set_timer）：
pygame.time.set_timer(pygame.USEREVENT, 60000)
pygame.time.set_timer(pygame.USEREVENT, 1000)
