• Discord bot returning odd error message and not playing sound

  26 February 2020, by Ravenr_

  I am attempting to create a function of my discord bot that will join your voice channel then play something from youtube as specified in the command

  i.e. $play <youtube link="link"></youtube>

  The problem is that my bot joins the voice channel but doesn’t play any sound and outputs an error to the console that I dont know how to fix

  My Code:

  const ytdl = require("ytdl-core");
  
  module.exports = {
  
      name: 'play',
  
      description: 'initiates music methods of the bot',
  
      execute(msg, args){
  
          var servers = {};
  
  
  
          function play(connection, msg){
  
              var server = servers[msg.guild.id];
  
  
  
              server.dispatcher = connection.playStream(ytdl(server.queue[0], {filter: "audioonly"}));
  
              server.queue.shift();
  
  
  
              server.dispatcher.on("end", function(){
  
                  if(server.queue[0]){
  
                      play(connection, msg);
  
                  }else{
  
                      connection.disconnect();
  
                  }
  
              });
  
  
  
  
  
          }
  
          if(!args[1]){
  
              return msg.channel.send("you need to provide a link");
  
          } 
  
          if(!msg.member.voiceChannel){
  
              return msg.channel.send("You must be in a voice channel to use this feature");
  
          }
  
          if(!servers[msg.guild.id]) servers[msg.guild.id] = {
  
              queue: []
  
          }
  
          var server = servers[msg.guild.id];
  
          server.queue.push(args[1]);
  
          if(!msg.guild.voiceConnection) msg.member.voiceChannel.join().then(function(connection){
  
              play(connection, msg);
  
          })
  
      }
  
  }

  The Error:

  for reference these are the links I tested it with 1 & 2

  I’m not sure how to make queue[0] a string, which is what I assume the problem is.

  I was thinking of using a toString() i.e. server.queue[0].toString() but I think that will just return the memory address.

  If anyone can help me know what the issue is or how to fix it, that would be great.

  Here is the code

  


  const ytdl = require("ytdl-core");
const Discord = require("discord.js");

var servers = {};

module.exports = {
  name: "play",
  description: "this is a music play command!",
  execute(message, args) {
  
  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[0]) {
      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[0]);
     
    if (!message.member.voice.connection) message.member.voice.channel.join().then(function(connection) {
    play(connection, message);
    })
  },
};


  


  I would like to know which directory I should put FFmpeg.

  


  I would also like to know if the FFmpeg executable has to be in a folder or compressed or if i can just place the executable in a certain directory

  


  I am hosting my bot using Heroku on a Mac using Discord.js V12

  


  Please help.

  


  Thanks!

  


• Nomenclature #4519 (Nouveau): Renommage de terminologie (blacklist / whitelist)

  13 July 2020

  En lisant la compilation [PHP Annotated – June 2020](https://blog.jetbrains.com/phpstorm/2020/06/php-annotated-june-2020/) on tombe sur ce point :

  [[RFC] Change terminology to ExcludeList](https://wiki.php.net/rfc/change-terminology-to-excludelist) — The topic of renaming offensive terms has not been overlooked by the PHP world either. There have been [heated discussions](https://externals.io/message/110515) in the Internals.
  In the PHP core, the change affects only one thing: the configuration directive `opcache.blacklist_filename` should be renamed to `opcache.exclude_list_filename`.
  Many other PHP tools have already made changes in this regard: [PHPUnit](https://github.com/sebastianbergmann/phpunit/blob/master/ChangeLog-9.3.md#930---2020-08-07), [Drupal](https://www.drupal.org/project/drupal/issues/2993575), [Xdebug](https://github.com/xdebug/xdebug/commit/63b43b51e43b794cf8cd740e54089b2b7320fbe1), [Yii](https://github.com/yiisoft/yii2/pull/18104), [Composer](https://github.com/composer/composer/pull/8957) (+ [working with non-master Git branches](https://blog.packagist.com/composer-and-default-git-branches/)).

  C’est certainement intéressant aussi de songer à ces renommages chez nous également, utilisés à quelques endroits.
