Discord.js 我的“帮助”命令不起作用

Question

所以基本上我已经为我的 discord.js 机器人创建了一个帮助命令，我尝试在机器人中实现一个页面系统，但我有两个问题。 1：每当我对表情符号做出反应时，机器人都会滞后，有时它不会更改页面，以及 2：命令不会分成两半，因此我无法将命令的两半显示到单独的页面上，这样第一个嵌入不是那么长。 这是我的代码

const {
    MessageEmbed
} = require("discord.js");
const {
    stripIndents
} = require("common-tags");
const {
    getMember,
    formatDate
} = require("../../functions.js");
const viewPerms = require("../../cmdviewperms.json");

module.exports = {
    config: {
        name: "help",
        aliases: ["?"],
        category: "Info",
        description: "Returns help information",
        usage: "!help",
    },
    run: (client, message, args) => {
        let cmds = client.commands;
        let allUsers = {
            Everyone: [],
            ADMINISTRATOR: []
        }

        for (let value of cmds) {
            let category = value[1].config.category;
            viewPerms.forEach(e => {
                if (e.cmdGroup.toLowerCase() == category.toLowerCase()) {
                    //console.log(`CATEGORY OF ${value[1].config.name} IS ${e.cmdGroup}`)

                            allUsers[x].push(value[1].config);

我看到浏览此代码的第一个问题是在从split()获得的数组上使用Math.ceil() ) ，这没有任何意义，因为Math.ceil()只接受数字。 这就是导致您的帮助文本没有分成两页的原因。 再往下，您的两个消息反应收集器forw和back都在寻找相同的反应，因为您使用相同的过滤器创建了它们。 每次点击任一反应时都会执行这两个回调，因为这两个反应都通过了过滤器。 这使得页面是否实际切换成为一个问题。 让收集器使用两个不同的过滤器，每个过滤器只寻找正确的反应。 我没有逐行查看代码，因此可能存在更多问题，但这是我看到的两个主要问题。
