Discord.js ReactionCollector 帮助菜单 - 重置表情符号

Question

我正在使用以下代码为 Discord 机器人创建帮助菜单。

let pages = ['Page one!', 'Second page', 'Third page'];
let page = 1; 

    const embed = new Discord.RichEmbed() // Define a new embed
    .setColor(0xffffff) // Set the color
    .setFooter(`Page ${page} of ${pages.length}`)
    .setDescription(pages[page-1])

    message.channel.send(embed).then(msg => {

    msg.react('⬅').then( r => {
        msg.react('➡')

        // Filters
        const backwardsFilter = (reaction, user) => reaction.emoji.name === '⬅' && user.id === message.author.id;
        const forwardsFilter = (reaction, user) => reaction.emoji.name === '➡' && user.id === message.author.id;

        const backwards = msg.createReactionCollector(backwardsFilter, {timer: 6000});
        const forwards = msg.createReactionCollector(forwardsFilter, {timer: 6000});

        backwards.on('collect', r => {
            if (page === 1) return;
            page--;
            embed.setDescription(pages[page-1]);
            embed.setFooter(`Page ${page} of ${pages.length}`);
            msg.edit(embed)
        })

        forwards.on('collect', r => {
            if (page === pages.length) return;
            page++;
            embed.setDescription(pages[page-1]);
            embed.setFooter(`Page ${page} of ${pages.length}`);
            msg.edit(embed)
        })
    })
})

}

除了我必须在表情符号上单击两次才能移至 next/previous 页面外，它可以正常工作。我想我需要删除表情符号，然后在默认设置中重新加载它们。

有人知道这样做的最佳方法吗？或者如果我需要做其他事情？

Answer 1

https://discord.js.org/#/docs/main/stable/class/MessageReaction?scrollTo=remove

r.remove(r.users.filter(u => u === message.author).first());

里面两个收集器都应该做一个工作。

编辑

如果你想让每个用户都能使用这个菜单，最好改用这个过滤器：

.filter(u => !u.bot)

以防万一有人偶然发现并尝试在当前版本的 DJS 上使用此代码并出错，这里是如何在当前版本的 Discord.JS (v12.2.0) 中编写整个函数:

注意：这假定您已经传递了客户端、消息和可选的任何参数

编辑：如果用户选择后退按钮但已在第一页，或前进按钮但已在最后一页，机器人将删除反应

const Discord = require('discord.js')
let pages = ['Page one!', 'Second page', 'Third page']
let page = 1 

const embed = new Discord.MessageEmbed() // Define a new embed
.setColor(0xffffff) // Set the color
.setFooter(`Page ${page} of ${pages.length}`)
.setDescription(pages[page-1])

message.channel.send({embed}).then(msg => {
  msg.react('⬅').then( r => {
    msg.react('➡')

    // Filters
    const backwardsFilter = (reaction, user) => reaction.emoji.name === '⬅' && user.id === message.author.id
    const forwardsFilter = (reaction, user) => reaction.emoji.name === '➡' && user.id === message.author.id

    const backwards = msg.createReactionCollector(backwardsFilter, {timer: 6000})
    const forwards = msg.createReactionCollector(forwardsFilter, {timer: 6000})

    backwards.on('collect', (r, u) => {
        if (page === 1) return r.users.remove(r.users.cache.filter(u => u === message.author).first())
        page--
        embed.setDescription(pages[page-1])
        embed.setFooter(`Page ${page} of ${pages.length}`)
        msg.edit(embed)
        r.users.remove(r.users.cache.filter(u => u === message.author).first())
    })

    forwards.on('collect', (r, u) => {
        if (page === pages.length) return r.users.remove(r.users.cache.filter(u => u === message.author).first())
        page++
        embed.setDescription(pages[page-1])
        embed.setFooter(`Page ${page} of ${pages.length}`)
        msg.edit(embed)
        r.users.remove(r.users.cache.filter(u => u === message.author).first())
    })
  })
})

希望这对任何人都有帮助:)
