Question

我已经问了一个与此相关的问题，但是我得到的答案有点瑕疵，直到现在我才注意到。我希望仅当message.author的最高角色高于上述用户的最高角色时，才能使用add role命令。这是我上次查询时得到的答案：

const highest = member.roles.highest; // this is the members highest role

// if role is higher or equal to highest role
if(highest.comparePositionTo(role) <= 0)
  return message.channel.send('You cannot add roles equal/higher to that member\'s highest role')

尽管有效，但不是我想要的，该命令仅在角色message.author提到的角色低于提到的用户的最高角色时才有效。所以我将其修改为：

const { MessageEmbed } = require("discord.js");

module.exports = {
  name: "addrole",
  description: "adds a role to a member",
  execute: async (message , args) => {
    if (!message.member.hasPermission("MANAGE_ROLES")) return message.channel.send("Invalid Permissions")
    let member = message.mentions.members.first();
    let role = message.mentions.roles.first();
    if (!member)
      return message.reply("Please mention a valid member of this server");
    if (!role) return message.reply("please mention a valid role of this server");

    const highest = message.author.roles.highest;

    if(highest.comparePositionTo(role) <= 0)
    return message.channel.send(`You cannot add roles equal/higher to that member's highest role`)

    let addroleembed = new MessageEmbed()
    .setTitle(`:white_check_mark: ${role.name} has been added to ${member.user}`)
    .addField(`hippity hoppity this role is now ${member.user}'s property`)
    .setFooter(`Action performed by ${message.author.tag}`)
    .setColor('77B255')
   addroleembed.setTimestamp();

    member.roles.add(role);
  message.channel.send(addroleembed)

}}

但这似乎不起作用。我收到错误消息“ TypeError：无法读取未定义的属性”最高”。如果有人可以在这里帮助我，我将不胜感激

Answer 1

const highest = message.author.roles.highest;

消息的

作者是用户，用户没有角色。这就是说它的原因：cannot read prperty of undefined因为author.roles不是问题。您必须获得成员才能获得角色。这样做：

const highest = message.member.roles.highest;

在这里，您将邮件的作者（用户）作为GuildMember（成员），然后要求该成员担任最高职务。

比较消息作者角色
