当我在pygame新建一个画面时，你必须反复点击退出按钮才能关闭window

Question

在我的 pygame 游戏中，当玩家死亡时，我运行一个 game_over() 函数，它显示一个屏幕“GAME OVER 按 E 退出或按 R 重新启动。”但是虽然是运行ning，但是如果你想关闭window，你必须点击多次，点击E也是如此。即使你点击R并重新启动，你也必须这样做, 但在 game_over() 有运行.

之前

这里是game_over():

def game_over():
running = False
while not running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = True
            pygame.QUIT
        if event.type == pygame.KEYDOWN:
            if event.key == pygame.K_r:
                player.score = 0
                main()
                break
            if event.key == pygame.K_e:
                running = True
                pygame.QUIT

    WIN.fill(BLACK)
    game_over = BIGFONT.render('GAME OVER', False, WHITE)
    WIN.blit(game_over , (200 , 175))

    instructions = SMALLFONT.render(f'You scored {player.score}. Press R to restart or E to exit' , False , WHITE)
    WIN.blit(instructions , (145 , 290))

    pygame.display.flip()

Answer 1

此处（以及 'e'）您将 'running' 设置为 true，这会打破该循环。下面一行 pygame.QUIT。什么都不做 pygame.QUIT 是变量，不是函数，你的意思可能是 pygame.quit().

while not running:
    for event in pygame.event.get():
        if event.type == pygame.QUIT:
            running = True
            pygame.QUIT

然而，如果 game_over() 是 return 一个 restart bool，那么主句柄要么重新启动，要么只是将 'done' 设置为 True 并让主循环自然结束。

 if game_over():
     done = True
 else:
     reset()

当我在pygame新建一个画面时，你必须反复点击退出按钮才能关闭window

When I make a new screen in pygame, you have to repeatedly click the exit button to close the window
