Question

因此，基本上，我已经为discord.js机器人发出了帮助命令，并尝试在该机器人中实现页面系统，但是有两个问题。 1：每当我对表情符号做出反应时，机器人就会停滞，有时它不会更改页面； 2：命令不会分成两半，因此我无法将命令的两半显示在单独的页面上，因此第一次嵌入时间不长。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}`)
                    if (value[1].config.bypassUsers) {

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

我看到的这段代码的第一个问题是在从Math.ceil()获得的数组上使用split()，这没有任何意义，因为Math.ceil()仅需要数字。这就是导致您的帮助文本无法分为两页的原因。再往下看，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。每当两个反应都被执行时，两个回调都将执行，因为两个反应都通过了过滤器。无论页面是否实际切换，这都是一个折腾。使收集器使用两个不同的过滤器，每个过滤器仅用于寻找正确的反应。我没有逐行查看代码，因此可能会有更多问题，但这是我看到的两个主要问题。

Discord.js我的“帮助”命令不起作用
