• When I try to play my Music Discord Bot it doesn't play music

  1er juin 2020, par EthanDevelops

  When I try to play my Music Discord Bot it doesn't play music. It uses ytdl-core and ffmpeg
My code is :

  



  const Discord = require('discord.js');
const bot = new Discord.Client

const ytdl = require("ytdl-core")


const token = 'API TOKEN'

const PREFIX = '?';

var version = '1.2';

var servers = {};

bot.on('ready', () =>{
    console.log('This bot is online!' + version);
})

bot.on('message', message => {

    let args = message.content.substring(PREFIX.length).split(" ");

    switch(args[0]){
        case 'play':

            function play(connection, message){
                var server = servers[message.guild.id];

                server.dispatcher = connection.play(ytdl(server.queue[0], {filter: "audioonly"}))

                server.queue.shift();

                server.dispatcher.on("end", function(){
                    if(server.queue[0]){
                        play(connection, message);
                    }else {
                        connection.disconnect();
                    }
                });



            }



            if(!args[1]){
                message.channel.send("You need to provide a link!")
                return;
            }

            if(!message.member.voice.channel){
               message.channel.send("You must be in a Voice Channel to play the bot!")
               return;
            }

            if(!servers[message.guild.id]) servers[message.guild.id] = {
                queue: []
            }

            var server = servers[message.guild.id];

            server.queue.push(args[1]);

            if(!message.guild.voice) message.member.voice.channel.join().then(function(connection){
                play(connection, message);
            })

        break;
    }



    });


    bot.login(token);

• How to make a basic youtube music bot work with searching titles instead of the URL

  21 janvier 2021, par Brandon

  Hello so i've followed this tutorial and added this code to my current bot to make it have a music bot function. Im wondering how to make the following code work with the youtube search function, for example right now I have to do !play URL but I would also like to be able to do !play name of song then the bot will search and play the most matched song.

  



  I am new to javascript but I know I shouldn't be looking for handouts, but some help would be appreciated.
