你好Stackoverflow社区！
我正在尝试创建的反应收集器开关有一些问题，并被卡住了。我想要这段代码很简单；当人们对一种颜色做出反应时，他们将获得颜色角色，他们的反应将被删除，因此，如果他们想要更改，他们只会对一种新颜色做出反应，依此类推。 但是我似乎无法使其正常工作。我没有收到任何错误消息，我只是没有任何角色。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");

答案 0 :(得分：1)
问题是reaction.emoji.name === unicode reaction name
因此，白色将是⬜，而不是white
一种方法是没有hardCode，只需创建带有一些参数的array，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));
};
