About

Pycord and Wavelink try to keep the playing of audio as simple and easy as possible, to keep making Discord bots of any kind easy for all audiences. This guide provides simple and easy examples of using the audio playing feature.

For users that want extra examples, you can find some in Pycord's GitHub repository.

Starting out​

First you need to run a Lavalink Server to connect with. There a multiple documentations to do this, so we are not covering that here.

You also need to install the wavelink library.

Installing wavelink
python3 -m pip install wavelink

You will now want to connect to your server via a node.

Connect Node with Lavalink
import discord
import wavelink

bot = discord.Bot()

async def connect_nodes():
  """Connect to our Lavalink nodes."""
  await bot.wait_until_ready() # wait until the bot is ready

  await wavelink.NodePool.create_node(
    bot=bot,
    host='0.0.0.0',
    port=2333,
    password='youshallnotpass'
  ) # create a node

Now you are finished making your node! Next, you will want to:

  1. Making a play command
  2. Adding connect events

Making a play command​

To make a play command, you will need to make a function to connect and play audio in a voice channel.

Play Command Example
@bot.slash_command(name="play")
async def play(ctx, search: str):
  vc = ctx.voice_client # define our voice client

  if not vc: # check if the bot is not in a voice channel
    vc = await ctx.author.voice.channel.connect(cls=wavelink.Player) # connect to the voice channel

  if ctx.author.voice.channel.id != vc.channel.id: # check if the bot is not in the voice channel
    return await ctx.respond("You must be in the same voice channel as the bot.") # return an error message

  song = await wavelink.YouTubeTrack.search(query=search, return_first=True) # search for the song

  if not song: # check if the song is not found
    return await ctx.respond("No song found.") # return an error message

  await vc.play(song) # play the song
  await ctx.respond(f"Now playing: `{vc.source.title}`") # return a message

Now playing: Never Gonna Give You Up

Now that you've done this, the only thing left to do is make your connect events.

Adding connect events​

The final step to this guide is connecting the node to your server when the bot goes online.

To make it, you will want to do the following:

Adding connect events
@bot.event
async def on_ready():
  await connect_nodes() # connect to the server

@bot.event
async def on_wavelink_node_ready(node: wavelink.Node):
  print(f"{node.identifier} is ready.") # print a message

bot.run("token")

Congratulations! You have now implemented voice playing into your bot! Most bots and Discord API wrappers don't have this as a feature, so this is quite an accomplishment. Thankfully, Pycord makes it easy to make complex bots so that you can get even the most advanced of ideas down.
