python - 窗口在 10 秒内未关闭

Question

我想在 10 秒后完成动画。为此，我在动画中添加了计时器 start_ticks = pygame.time.get_ticks()并在 for 中检查这个计时器循环 seconds > max_simulation_time .

但是，窗口不会在 10 秒内关闭。只有当我在屏幕上移动鼠标时它才会关闭。有点奇怪的行为。我究竟做错了什么？如果它可能是一个重要的细节，我会在 Jupyter notebook 中运行代码。

class Environment():

    def __init__(self, title):

        pygame.init()

        self.screen = pygame.display.set_mode((800, 800))
        pygame.display.set_caption(title)

        # ...


    def run(self):   
        carryOn = True
        max_simulation_time = 10
        start_ticks = pygame.time.get_ticks()
        while carryOn:
            seconds=(pygame.time.get_ticks()-start_ticks)/1000
            for event in pygame.event.get():
                if (seconds > max_simulation_time):
                    carryOn = False
                    pygame.display.quit()
                    pygame.quit()
                    quit()

            agent_action = 1
            self.all_sprites.update(self.screen, agent_action)
            self.screen.fill((0, 40, 0))
            self.all_sprites.draw(self.screen)
            pygame.display.flip()


if __name__ == "__main__":
    env = Environment("TEST")
    env.run()

另外，有没有办法只break 10 秒后的动画并从头开始(重置)，不关闭窗口？

更新:

如果我这样做:

class Environment():

    def __init__(self, title):

        pygame.init()

        self.screen = pygame.display.set_mode((800, 800))
        pygame.display.set_caption(title)

        # ...


    def run(self):   
        carryOn = True
        max_simulation_time = 10
        start_ticks = pygame.time.get_ticks()
        while carryOn:
            seconds=(pygame.time.get_ticks()-start_ticks)/1000
            if (seconds > max_simulation_time):
                carryOn = False
                pygame.display.quit()
                pygame.quit()
                quit()
            for event in pygame.event.get():
                if (event.type == pygame.QUIT):
                    carryOn = False
                    pygame.display.quit()
                    pygame.quit()
                    quit()
        # ...

if __name__ == "__main__":
    env = Environment("TEST")
    for epochs in range(1,3):
        env.run()

<...> 然后我得到以下错误:

    515     #env.run()
    516     for epochs in range(1,3):
--> 517         env.run()

<ipython-input-1-102fa6124bbf> in run(self)

--> 473             for event in pygame.event.get():
    474                 if (event.type == pygame.QUIT):
    475                     carry_on = False

我认为这可能与检查是否仅在 for event in pygame.event.get() 循环中超过了 max_simulation_time 有关。

这就是为什么它只在您移动鼠标时发生。在进入该 for 循环之前检查您是否超过了该时间。
