当我的暂停在pygame中播放我的game_loop函数时，如何阻止我的游戏重启？

Question

所以，我在pygame中制作一个简单的视频游戏，它非常接近完成。 我正在我的暂停屏幕上工作，但是当我点击p（我选择的按钮）时它暂停了但是当我点击继续时它重新启动游戏。 我查了一下代码，发现没有错。 然后，我在这里找到了问题论坛并查找了问题，我找到了一些东西，但他们并没有像我一样做代码，最重要的是答案很难理解。 暂停功能paused() ，取消暂停，是因为unpause() 。 你能试着找出它出错的地方吗？ 这是我的源代码：

ship_width = 96
gameDisplay = pygame.display.set_mode((display_width,display_height))
pygame.display.set_caption('_Asteroid Belt_')

Answer 1

您似乎没有在pause()函数中取消pause() 。

你应该添加这样的东西：

def paused():
    while pause:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                pygame.quit()
                quit()
            if event.type == pygame.K_p:
                unpause()

Answer 2

在我的代码中，我将取消暂停按钮功能设置为game_loop()而不是game_loop() unpause() 。 因此每次我去取消停止时，我都会重新启动游戏循环！ 这是一个示例，您必须注意代码的每个部分，而不仅仅是出错的函数。
