How to check if bot is connected to a channel? | discord.py

Question

I've decided to try making my discord bot play music, but I've gotten stuck already. Mainly due to the fact I can't find any sources to help with the current version, I've been winging everything from the docs. However, I can't figure out how to check if the bot is connected to a voice channel.

I have tried if not Client.is_connected():, however that didn't work. If there are any updated sources to help me get the basics of discord.py's voice features, please give me a link :) Here is my code so far:

# ----- ATTEMPT AT VOICE COMMANDS ------
#discord.opus.load_opus() - what goes in bracket???

@client.command(name="join", pass_ctx=True)
async def join(ctx):
    #if not is_connected(): - Client.is_connected() not working

    user = ctx.message.author
    vc = user.voice.channel
    await vc.connect()
    await ctx.send(f"Joined **{vc}**")

    #else:
    #    await ctx.send("I'm already connected!")

@client.command(name="disconnect", pass_ctx=True)
async def disconnect(ctx):
    # if not is_connected(): - once again can't work it out
    vc = ctx.message.guild.voice_client # i don't even know how this worked :D
    await vc.disconnect()

    #else:
    #    await ctx.send("I'm not connected to any channels")

@client.command(name="play", pass_ctx=True)
async def play(ctx, songurl=None):
    if not songurl: # this works at least
        await ctx.send("Please specify a song")
        return
    if not is_connected(): # once again, how to check if bot is connected?
        vc = ctx.message.author.voice.channel
        if not vc: # i think this should work
            await ctx.send("You're not in a voice channel!")

        await vc.connect()
    # haven't even worked out anything past this point and it's broken

ps: sorry for just dumping my whole vc section but i don't understand a lot

Really all that matters here is the play command, but I included the others just because (as you can see from my comments) I don't understand LOTS of what is going on. How should I go about this? Are there any good sources for the current version? Thanks in advance.

A bot can be connected to voice in multiple guilds at the same time, so you need to get the VoiceClient for the appropriate guild from Client.voice_clients and then check VoiceClient.is_connected:

def is_connected(ctx):
    voice_client = get(ctx.bot.voice_clients, guild=ctx.guild)
    return voice_client and voice_client.is_connected()

name VoiceClient is not defined – xupaii Jun 22 '19 at 21:11
My code doesn't reference the `VoiceClient` class directly, does yours? – Patrick Haugh Jun 22 '19 at 21:12
I did `if VoiceClient.is_connected():`, after putting this function in, am I missing something? – xupaii Jun 22 '19 at 21:14

Just do `if is_connected(ctx):`. The `VoiceClient` class is what each individual voice client is an instance of. You should only be calling the methods of an instance, like I do with `voice_client` above. – Patrick Haugh Jun 22 '19 at 21:15
Also, regarding my other question, is there somewhere where I can learn discord.py voice chat? Like a guide? I can't find anything – xupaii Jun 22 '19 at 22:08
You can look at the example voice bot: https://github.com/Rapptz/discord.py/blob/master/examples/basic_voice.py Looking at that, you can also access the voice client through `ctx.voice_client` – Patrick Haugh Jun 22 '19 at 22:10
Where does the `get` function comes from? – Vencovsky Sep 27 '20 at 16:57

you could also do

client.command()
async def join(ctx):
    user = ctx.message.author
    vc = user.voice.channel

    voice = discord.utils.get(client.voice_clients, guild=ctx.guild) # This allows for more functionality with voice channels

    if voice == None: # None being the default value if the bot isnt in a channel (which is why the is_connected() is returning errors)
        await vc.connect()
        await ctx.send(f"Joined **{vc}**")
    else:
        await ctx.send("I'm already connected!")

After a bit of experimentation with my bot, I found that something similar to this may work for you. It's also pretty quick and easy.

if ctx.guild.voice_client in  bot.voice_clients:
    # Do something here

I used this with the on_message event, but it could likely work in your use case as well by doing:

if not ctx.guild.voice_client in bot.voice_clients:
    # Do something else here
