因此，这是我的第一个问题，但我有点迷失了我的代码，所以我想知道是否有人可以告诉我，为什么它崩溃。我对python相当陌生(虽然我用其他语言编写了很多代码)。所以我的游戏基本上是猫和老鼠的游戏，白色是猫，黑色是老鼠.你明白了。唯一的问题是，当我打开它时，我看到blit文本大约一秒，然后它崩溃了，我试着查看了很多代码，但是都没有用，所以如果有人帮我查看它，我会非常感激的。(我可能漏掉了一些愚蠢的东西，比如错误的缩进)。

你犯了一个很小但却是致命的错误。您忘记导入时间模块了！

代码语言：javascript
复制
import time

将这一行直接放在import pygame之后，这将解决您的第一个问题。

下一个问题是，您在每个帧中导致了一个time.sleep。当你打开一个游戏窗口时，你永远不想要一个time.sleep调用。如果在这段时间内，用户与窗口进行任何交互，程序将变得没有响应，并崩溃。我创建了一个小函数，并将其替换为延迟，这样用户就可以在暂停时与屏幕交互。

这是许多小事情之一，将导致一个新的游戏开发人员撕掉你的头发！

我建议把这本书读一读：http://www.apress.com/gp/book/9781590598726

它解释了所有的游戏惯例和标准。这是我以前开始玩游戏开发的书。

你的碰撞检测很难击中。这只猫一定是在老鼠的顶端才能赢。如果这是您想要的，这是您的工作代码。如果你只想触碰一下，说句话，我就教你怎么做。

以下是代码：

好的，先试试吧！希望这能帮上忙，祝你玩游戏好运！

为了让用户在两个矩形触摸时获胜，我对鼠标的每个角落使用了对撞点函数。此函数检测指定的点是否位于矩形对象内。

在移动每个矩形之后，这个部分就会出现：

代码语言：javascript
复制
windowSurface.fill(red)
cat = pygame.draw.rect(windowSurface, black, ([xcord,ycord,20,20]))
mouse = pygame.draw.rect(windowSurface, white, ([xCord,yCord,20,20]))

if cat.collidepoint(xCord, yCord) or cat.collidepoint(xCord + 20, yCord) or cat.collidepoint(xCord, yCord + 20) or cat.collidepoint(xCord+20, yCord+20):
    text='White Wins'
    windowSurface.fill((255,255,255))
    windowSurface.blit(font.render(text, True, (0, 255, 0)), (500, 100))
    pygame.display.flip()
    clock.tick(60)
    create_delay(10)
    exit=True
    continue

clock.tick(60)

如果你需要额外的帮助，请不要犹豫。
