我正在尝试创建一个命令，该命令允许我为游戏创建多个项目。我的主要问题来自该命令的可重用性。事实上，其中一些命令有超过 9 个参数，这让我转向了key_define。我也查看了，property但我很难找到有关如何充分使用它的可用文档，所以我改用键值。
总体而言，我的代码所做的就是创建许多快捷方式，以便以后可以将其放入我的文档中。假设我创建了这两个字符：
\createCharacter{Barry}<main>[lastname=Allen, prof=scientist]{39}
和
\createCharacter*{Jessy}<side>[lastname=Quick, nickname=Jess, prof=professional runner]{24}
当我调用时，\mainFName我得到了“Barry”和\sideFName“Jessy”，正如预期的那样，但是当我调用时，\sideLName我得到了“Quick”，\mainLName我得到的也是“Quick”。所以发生的事情是，它没有采用创建时的值，而是重新评估了它的“当前值”（即最后创建的字符）。
因此，以下是我想要更正并使其工作的代码，而不必为每个角色创建所有 tl_new，最终创建每个物品、魔法和其他可能有用的内容。如果我能够用\createCharacter类似的东西来完成\tl_new:c {\l_#4_firstname_tl}，那就太完美了。

我不会使用\NewDocumentCommand这些宏。问题是你存储的是变量，而不是它们的值。

您需要传递变量的内容。组也很重要，否则角色的未设置值将从上一个角色继承。好的，除非您设置全部值每一个特点。
