Question

我试图用Lua和Discordia库编写一个Discord机器人。我一直在尝试实现一种方法，以检查运行命令的人员是否具有这样做的作用。该角色的ID是adminid变量。在我执行权限检查之前，该机器人一直在工作，现在它崩溃并

Answer 1

您正在使用.运算符而不是:运算符调用函数，这将导致被调用函数的第一个参数（称为self）无效。这是因为当您呼叫thing:function(parameter)时，lua实际上会呼叫thing.function(thing, parameter)。错误消息指出self（通常是第一个参数的变量名）已被索引（例如self[2]或self.b），但self是一个数字值（{{ 1}}）。

要解决此问题，只需更改

adminid

到

if member.hasRole(adminid) == true then

此外，不需要测试if member:hasRole(adminid) == true then，因为它只会在== true的右侧返回true，这将不执行任何操作（除非您专门测试true类型，但通常不是这种情况。

Answer 2

如果您继续需要答案。
将 message.member 更改为 message.author
这将返回用户，让成员执行（对于公会）message.guild:getMember(author or author.id)
