discord.js 列出我所有的机器人命令

问题描述

我使用 discord.js 制作了一个不和谐机器人，并尝试执行帮助命令向用户显示所有可用命令.

i made a discord bot with discord.js and tried to do a help command to show the user all available commands.

示例命令:avatar.js

module.exports.run = async(bot, message, args) => {
    let msg = await message.channel.send("doing some magic ...");
    let target = message.mentions.users.first() || message.author;

    await message.channel.send({files: [
        {
            attachment: target.displayAvatarURL,
            name: "avatar.png"
        }
    ]});

    msg.delete();
}

module.exports.help = {
    name: "avatar",
    description: "show the avatar of a user",
    usage: "[@user]"
}

然后我尝试发送带有完整命令列表的消息，例如:

Then i tried to send a message with the complete list of the commands like:

• 命令 1
• 说明
• 用法
• 命令 2
• 说明
• 用法
• ...

help.js

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

module.exports.run = async(bot, message, args, con) => {
    fs.readdir("./cmds/", (err, files) => {
        if(err) console.error(err);

        let jsfiles = files.filter(f => f.split(".").pop() === "js");
        if(jsfiles.length <= 0) {
            console.log("No commands to load!");
            return;
        }

        var namelist = "";
        var desclist = "";
        var usage = "";

        let result = jsfiles.forEach((f, i) => {
            let props = require(`./${f}`);
            namelist = props.help.name;
            desclist = props.help.description;
            usage = props.help.usage;
        });

        message.author.send(`**${namelist}** 
${desclist} 
${usage}`);
    });
}

module.exports.help = {
    name: "help",
    description: "show all commands",
    usage: ""
}

我的代码有点工作，但它只发送第一个命令.

my code is kinda working but it only sends the first command.

我对 javascript 很陌生，我找不到解决方案.我试图用谷歌搜索所有关于 foreach 地图不和谐集合和东西的东西，但我找不到将结果组合在一起的例子.

Im pretty new to javascript and i can't find a solution to this. I tried to google everything on foreach maps discord collections and stuff but i cant find a example where the results get combined together.

如果有人可以帮助我或给我一个提示，我可以在哪里搜索类似的东西.会很棒.

If anybody can help me or give me a hint where i can search for something like this. Would be awesome.

推荐答案

你的代码只发送一个命令的原因是你的代码只调用 message.author.send('...' 一次.您成功地使用每个文件中的数据设置了变量 namelist、desclist 和 usage，但您的 .forEach(... 循环只是在移动到下一个文件时覆盖所有数据.

The reason your code is only sending the one command is because your code only calls message.author.send('...' once. You successfully set the variables namelist, desclist, and usage with data from every file, but your .forEach(... loop just overwrites all of the data when it moves to the next files.

尝试在 .forEach(... 循环的每次迭代中发送数据，如下所示:

Try to send data inside each iteration of the .forEach(... loop like this:

var namelist = "";
var desclist = "";
var usage = "";

let result = jsfiles.forEach((f, i) => {
    let props = require(`./${f}`);
    namelist = props.help.name;
    desclist = props.help.description;
    usage = props.help.usage;

    // send help text
    message.author.send(`**${namelist}** 
${desclist} 
${usage}`);
});
