Discord.js 反应角色收集器开关

Question

你好 Stackoverflow 社区！

我正在尝试创建的反应收集器开关有点问题，但有点卡住了。我想要这段代码做的很简单；当人们对一种颜色做出反应时，他们获得了颜色角色，他们的反应被移除了，所以如果他们想要改变，他们只需对新颜色做出反应，等等。 但我似乎无法让它工作。我没有收到任何错误消息，我只是没有得到任何角色。先感谢您！！非常感谢！

代码：

const Discord = require("discord.js");

module.exports.run = async (bot, message, args, client) => {

const RandomColour = ("000000" + Math.random().toString(16).slice(2, 8).toUpperCase()).slice(-6);

    message.delete();

    const black = message.guild.roles.get("595509263754067969");
    const white = message.guild.roles.get("595510495902040074");
    const magenta = message.guild.roles.get("595510495902040074");
    const purple = message.guild.roles.get("595507863355654154");
    const red = message.guild.roles.get("595506989212106802");
    const orange = message.guild.roles.get("595507331396009986");
    const yellow = message.guild.roles.get("595507180183093248");
    const green = message.guild.roles.get("595507124574879744");
    const blue = message.guild.roles.get("595507043629268993");

    const filter = (reaction, user) => reaction.emoji.name === [
      'black' , 
      'white' , 
      'magenta' , 
      'purple' , 
      'red' , 
      'orange' , 
      'yellow' , 
      'green' , 
      'blue'].includes(reaction.emoji.name) && user.id === message.member.id;

    const embed = new Discord.RichEmbed()
        .setAuthor("Available Roles")
        .setDescription(`

        Black       ${black.toString()}   | ⬛

问题是，reaction.emoji.name === unicode reaction name 所以白色是⬜，而不是white

一种方法是没有硬编码，只需创建带有一些参数的数组，然后检查它:)

const Discord = require("discord.js");

module.exports.run = async (bot, message, args, client) => {
 const reactionRoles = [
        {
            name: 'white',
            reaction: '⬜',
            reactionRole: message.guild.roles.get('595510495902040074'),
        },
        {
            name: 'black',
            reaction: '⬛',
            reactionRole: message.guild.roles.get('595509263754067969'),
        },
    ];
    const RandomColour = Math.floor(Math.random() * Math.floor(16777215));
    const embed = new Discord.RichEmbed()
        .setAuthor('Available Roles')
        .setDescription(`${reactionRoles.map(r => `${r.name} | ${r.reactionRole.name} | ${r.reaction}`).join('\n')}`)
        .setFooter('React on the right emoji to get a colour.')
        .setColor(RandomColour)
        .setTimestamp();
    message.channel
        .send(embed)
        .then(async msg => {
            for (const r of reactionRoles) {
                await msg.react(r.reaction);
            }
            const filter = (reaction, user) => {
                return reactionRoles.map(r => r.reaction).includes(reaction.emoji.name) && user.id === message.author.id;
            };
            msg.awaitReactions(filter, { max: 1 })
                .then(collected => {
                    const reaction = collected.first();
                    let role = reactionRoles.find(r => r.reaction === reaction.emoji.name);
                    if (message.member.roles.has(role.reactionRole)) return message.reply('You are already has this role');
                    message.member.addRole(role.reactionRole);
                })
                .catch(collected => {
                    return message.channel.send("I couldn't add you to this role. If this keeps occouring, contact staff.");
                })
                .catch(err => console.log(err));
        })
        .catch(err => console.log(err));
};
