在不和谐中分配角色

Question

我正在制作一个不和谐的谋杀神秘机器人。

const Discord = require('discord.js');
const client = new Discord.Client();

client.on("message", (message) => {
    msg = message.content.toLowerCase();

    if (message.author.bot) {
        return;
    }
    mention = message.mentions.users.first();

    if (msg.startsWith("kill")) {
        if (mention == null) {
            return;
        }
        message.delete();
        mention.send('you are dead');
        message.channel.send("now done");
    }
});
client.login('my token');

我会在代码中添加什么，以便在被标记的人到达那里后，角色从活着变为死了？

Answer 1

// First, make sure that you're in a guild
if (!message.guild) return;

// Get the guild member from the user
// You can also use message.mentions.members.first() (make sure that you check that
// the message was sent in a guild beforehand if you do so)
const member = message.guild.member(mention);

// You can use the ID of the roles, or get the role by name. Example:
// const aliveRole = message.guild.roles.cache.find(r => r.name === 'Alive');
const aliveRole = 'alive role ID here';
const deadRole = 'dead role ID here';

// You can also use try/catch with await if you make the listener and async
// function:
/*
client.on("message", async (message) => {
  // ...
  try {
    await Promise.all([
      member.roles.remove(aliveRole),
      member.roles.add(deadRole)
    ]);
  } catch (error) {
    console.error(error);
  }
})
*/
Promise.all([
  member.roles.remove(aliveRole),
  member.roles.add(deadRole)
]).catch(console.error);

Promise.all表示同时启动添加和删除角色的承诺。 承诺是一个对象，可以解析为一个值或拒绝错误，因此.catch(console.error)记录所有错误。 我建议您也处理message.delete() 、 mention.send('you are dead')和message.channel.send("now done") 。

有关member.roles.remove()和member.roles.add()更多信息，请参阅GuildMemberRoleManager的文档。
