使用pygame.sprite.sprite与任何Python冲突

我是python编程新手，我正在制作一个外星人入侵游戏来练习。这是一个经典的游戏配置，你必须击落一排排外星人，然后他们才能到达底部并与你的飞船相撞

这是我的

我已经完成了大部分游戏，但是当我在

game\u函数

文件中添加

pygame.sprite.spritecollideny（）

时，我得到了

“属性错误：'组'没有属性'rect'”

我知道我可能遗漏了一些简单的东西，但我无法理解。很抱歉，在我发布问题时，为了节省时间，在复制和粘贴代码时，没有正确键入代码

我也在使用Ubuntu 14.04 LTS，并运行python-3.4.3。

阅读Pygame文档：

此函数要求单个精灵作为第一个参数，组作为第二个参数，但您使用

experions

作为第一个参数，ship作为第二个参数

你必须改变论点的顺序

顺便说一句：下次只需使用

print（）

-这是最常用的方法（如果您不知道如何调试）来检查变量中的内容并查看错误。

始终在问题中添加完整的错误消息（回溯）-还有其他有用的信息，即哪一行产生问题。现在在代码中显示这一行。编辑问题并使用按钮

{}

放置正确的代码-现在您的缩进不正确-因此它不可读。可以！再次感谢您的帮助！非常感谢。我知道我错过了一些简单的事情。这解决了问题。
