I am making a discord chatbot, but something I would like it to do is to join a random voice channel. I have tried the following from a different example, but you need to specify a channel ID. Which doesn’t suit my needs.

const channel = message.guild.channels.get('voiceChannelID');

I've also tried this from Check if a channel is a voice channel but it also requires a specific channel ID.

const channelObject = message.guild.channels.cache.get('channel id here'); // Gets the channel object
if (channelObject.type === 'voice') return; // Checks if the channel type is voice

It would be greatly appreciated if you could answer with some code that would find a random voice channel.

You can fetch all channels, filter them by their type and use Collection#random() to pick a random one from the returned collection:

let channels = await message.guild.channels.fetch();
let voiceChannels = channels.filter(ch => ch.type === 'GUILD_VOICE');
let randomVoiceChannel = voiceChannels.random();

Please note that in discord.js v13, VoiceChannel#type is GUILD_VOICE instead of voice. For more info see this answer.

Update: If you're using discord.js v12, you can use the following:

let channels = message.guild.channels.cache;
let voiceChannels = channels.filter((ch) => ch.type === 'voice');
let randomVoiceChannel = voiceChannels.random();

... and it's probably time to upgrade :)

I've had to grab all of the channels and filter out the voice channels before, so I just grabbed that code and flipped it around and added some random to it.

What I did:

let channels = Array.from(message.guild.channels.cache.keys());
const c = channels.filter(v => message.guild.channels.resolve(v).isVoice() == true);
const index = Math.floor(Math.random() * c.length);
const randomVoiceChannel = c[index];

The first line grabs all of the channels in the server.

The 2nd line removes the non-voice channels.

And finally the last 2 lines generate a random index from the array and outputs a value.

const randomVoiceChannel = Array.from(message.guild.channels.cache.keys()).filter(v => message.guild.channels.resolve(v).isVoice() == true)
[Math.floor(Math.random() * Array.from(message.guild.channels.cache.keys()).filter(v => message.guild.channels.resolve(v).isVoice() == true).length)];

nifty 1-liner (please don't use this its incredibly unreadable I just thought it was funny)

  • Thanks for your answers! Unfortunately the first answer returns `TypeError: message,guild.channels.fetch is not a function.` And the second one returns `Reference Error: interaction is not defined` – abcd efgh Jul 13 '22 at 13:41
  • @abcdefgh Please, next time write on these answers separately. I don't get a notification if instead of my post you send a response here. – Zsolt Meszaros Jul 13 '22 at 16:40
  • Oh sorry. I’m not sure how to add a comment for both of your answers. – abcd efgh Jul 13 '22 at 17:58
  • im so sorry i made a bunch of typos because for some reason i couldnt just copy paste from my testing environment, and i was using interactions instead of message – hamdatnoob Jul 13 '22 at 19:07
