在python编写小游戏时遇到TypeError。

Question

我在使用pgzrun进行游戏编程的时候，遇到了一个问题。
由于我的编程技术不太好，所以不知道如何解决。

游戏名字：
颜色选择小游戏

游戏玩法：
玩家需要在每个回合规定时间内点击7*7方格内所给出的一个随机颜色。如果点击正确则加1分，如果点击错误则游戏结束。玩家要尽可能的得到高分。

遇到问题：

对于这个问题我很是苦恼，希望热心的网友可以帮助我。我在这里提前说一声谢谢啦！

以下回答参考GPT并且由Bony-整理：
这个错误发生在创建Actor对象时。在draw函数中的这一行代码：

color=Actor(colors1[random.randint(0,48)])

在这里，你试图将Actor对象的image属性设置为colors1列表中一个随机位置上的Actor对象。但是，Actor对象不是一个字符串、字节串或os.PathLike对象，所以无法与文件系统路径拼接在一起，从而导致了TypeError错误。相反，应该将color属性设置为colors1列表中一个随机位置上的角色的image属性。因此，你可以将该行代码更改为：

color = colors1[random.randint(0, 48)].image

这将使程序从颜色角色中提取所需的图像，并将其赋值给color变量。
