由于我无法真正使用旧版游戏，因此我决定创建一个简单版的《人生游戏》。我现在有一个GameOfLife类，但是它运行很慢。当我单击某个单元格时，它需要一段时间才能激活/停用，等等。有人知道为什么它很慢吗？ FPSCLOCK是否有问题，或者我正在运行不应运行的东西？

pygame.display.flip()调用将重绘整个屏幕-您正在为每个重绘的单元格一次调用它。
将该调用从上面的draw_cell方法移至方法gen_update()的末尾，您应该会很好。更好的是，只需将其从任何方法中删除，并将其放置在主循环的末尾，就在调用时钟刻度之前：
def run(self):
while not self.game_over:
# Set the frames per second.
self.handle_events()
if self.next_iteration: # if next iteration is true, the next gen is created according to the rules.
self.create_next_gen()
# Updating
self.update_gen()
pygame.display.flip()
self.FPSCLOCK.tick(fps_max)
