Getting Started

A quick and easy bot example:

from discord.ext import commands


class Bot(commands.Bot):

    def __init__(self):
        super().__init__(command_prefix='>?')

    async def on_ready(self):
        print('Bot is ready!')


class Music(commands.Cog):
    """Music cog to hold Wavelink related commands and listeners."""

    def __init__(self, bot: commands.Bot):
        self.bot = bot

        bot.loop.create_task(self.connect_nodes())

    async def connect_nodes(self):
        """Connect to our Lavalink nodes."""
        await self.bot.wait_until_ready()

        await wavelink.NodePool.create_node(bot=bot,
                                            host='0.0.0.0',
                                            port=2333,
                                            password='YOUR_LAVALINK_PASSWORD')

    @commands.Cog.listener()
    async def on_wavelink_node_ready(self, node: wavelink.Node):
        """Event fired when a node has finished connecting."""
        print(f'Node: <{node.identifier}> is ready!')

    @commands.command()
    async def play(self, ctx: commands.Context, *, search: wavelink.YouTubeTrack):
        """Play a song with the given search query.

        If not connected, connect to our voice channel.
        """
        if not ctx.voice_client:
            vc: wavelink.Player = await ctx.author.voice.channel.connect(cls=wavelink.Player)
        else:
            vc: wavelink.Player = ctx.voice_client

        await vc.play(search)


bot = Bot()
bot.add_cog(Music(bot))
bot.run('YOUR_BOT_TOKEN')
