Python 为什么我在Evennia的一个命令会得到多个结果？

我正在制作一个文本游戏。我添加了一个名为Prop的新类型类。目前，它只有一个命令磨损。然后我创建了两个道具作为原型，并使用@spawn构建了它们。当我只拿着一个道具时，它的“穿戴”命令运行良好：穿戴手套返回您现在佩戴的是手套。但是，一旦我有了多个道具，我得到的就是.search消歧菜单，而我键入的任何东西似乎都不能真正消除歧义

我很确定这与cmdset合并有关，但我只能做到这一点。我做错了什么

事实证明，我没有得到一个。搜索消歧。相反，是命令本身被消除了歧义。解决方案是将CmdSet移动到对象以外的其他位置。然后，无论作用域中有多少对象，都只有一个命令
