Question

我正在为我的学校项目在pygame中制作一个简单的Tic Tac Toe游戏。我设法将一些代码放在一起（对不起，如果它有点乱，可能是我试图用来修复当前问题的代码的遗留问题），这在某种程度上可以正常工作。然而，我确实遇到了一个奇怪的错误，我不知道为什么，但似乎我的程序无法处理快速用户输入（如果用户点击非常快），而不是放一个圆然后十字架它可能会放2圆圈或2个十字架。如果用户进展相当慢，它工作正常，但我正在寻找一种摆脱这个问题的方法，如果有人能暗示我做一些我真的很感激。这是源代码：

Answer 1

pygame.event.get将检索队列中的所有事件，以便您可以同时获得多个更新。因为在填写图像时您没有检查轮到谁，所以您可以一次填写多个十字或圆圈。

为什么会这样：

        elif event.type == MOUSEBUTTONUP:
            mouseClick = True
            mouseX, mouseY = event.pos

在循环中mouseClick第一次被设置为True，但是因为队列中有多个事件，event.get（）有另一个要处理的元素，这次它运行mouseclick再次循环为True。但是这次我们仍然处于循环中，因为event.get()是一个多于一个的列表，所以：

        elif event.type == MOUSEMOTION:
            mouseX, mouseY = event.pos

现在执行此操作，但是mouseClick在处理此问题时错误地True，所以我们再次落入另一个声明中，这不是您想要的。

作为我所做的一个简短的总结，我将if句子的质量移动到循环中的for事件中，并使得当图片实际放在桌子上而不是这样做时，转弯增加或减少1当玩家点击时我做的另一件事是我添加了一个moveDone变量，它跟踪是否已经在当前循环中启动了更改板状态（get_mouse_overbox）的函数。希望这有助于某人，并再次感谢帮助shuttle87
