python - Pygame程序在按下红叉后并不总是退出

Question

我正在尝试使用 Pygame 制作一个简单的井字游戏。在玩游戏的过程中，有时需要按1次以上的“红叉”才能退出游戏。

while playing is True:
    clock.tick(30)
    if round_number % 2 == 1:
        current_player = 1
    else:
        current_player = 2

    while True:
        pygame.event.get()
        if pygame.event.get(eventtype=pygame.QUIT):
            pygame.quit()
            exit()
        if pygame.mouse.get_pressed()[0] == 1:
            break

    while True:
        pygame.event.get()
        if pygame.mouse.get_pressed()[0] == 0:
            break

    place_object(current_player, pygame.mouse.get_pos())
    print(round_number)
    pygame.display.update()
    if 7 < pygame.mouse.get_pos()[0] < 393 and 7 < pygame.mouse.get_pos()[1] < 393:
        round_number += 1

    if round_number >= 3:
        if check_win(board) != "No winner" and check_win(board) != "tie":
            message = f"The winner is {check_win(board)}!"
            message_display(message)
            pygame.display.update()
            playing = False
        elif check_win(board) == "tie":
            message_display("Game is tied...")
            pygame.display.update()
            playing = False

pygame.event.get()返回事件列表并将它们从队列中删除。
你必须循环处理列表，否则你会错过事件:

例如

for event in pygame.event.get():
    if event.type == pygame.QUIT:
        pygame.quit()
        exit()
