How to wait some time in pygame?
提问by bzzr
While I've been using time.waitin my code since I began learning Python and Pygame, I've been wondering if there are any other ways to do it and what are the advantages and disadvantages of each approach. For example, Pygame also has a pygame.time.wait. What's the difference between python's wait and pygame's wait functions? Which one is better? And are there other ways to wait some time besides using these two functions?
自从我开始学习 Python 和 Pygame 以来，我一直在我的代码中使用time.wait，我一直想知道是否还有其他方法可以做到这一点，以及每种方法的优缺点是什么。例如，Pygame 还有一个pygame.time.wait。python的wait和pygame的wait函数有什么区别？哪一个更好？除了使用这两个功能之外，还有其他方法可以等待一段时间吗？

For animation / cooldowns, etc: If you want to 'wait', but still have code running you use: pygame.time.get_ticks
对于动画/冷却等：如果您想“等待”，但仍有代码在运行，请使用：pygame.time.get_ticks
class Unit():
def __init__(self):
self.last = pygame.time.get_ticks()
self.cooldown = 300
def fire(self):
# fire gun, only if cooldown has been 0.3 seconds since last
now = pygame.time.get_ticks()
if now - self.last >= self.cooldown:
self.last = now
spawn_bullet()

For Python in general, you will want to look at the sleeplibrary.
一般来说，对于 Python，您需要查看sleep库。
For Pygame, however, using pygame.time.delay()will pause for a given number of milliseconds based on the CPU clock for more accuracy (as opposed to pygame.time.wait).
然而，对于 Pygame，使用pygame.time.delay()将根据 CPU 时钟暂停给定的毫秒数以获得更高的准确性（与 pygame.time.wait 相反）。
