How to use discord.py event handler on_voice_state_update to run only when a user joins a voice channel
18,428
A version working in 2020. Please not that my code behaves different in terms of the sent message.
from discord.ext.commands import Bot
bot = commands.Bot(command_prefix='!')
@bot.event
async def on_voice_state_update(member, before, after):
if before.channel is None and after.channel is not None:
if after.channel.id == [YOUR_CHANNEL_ID]:
await member.guild.system_channel.send("Alarm!")

I am trying to learn how to make a discord bot through
discord.py
and wanted to add a feature where a message would be sent from the bot whenever another user joined the voice channel that the bot is currently in. I do not know how to use the event handler itself and didn't understand their documentation enough to utilize it.from discord.ext.commands import Bot client = Bot(command_prefix="!") @client.event async def on_voice_state_update(before, after): await client.say("Howdy")
From my limited understanding of the documentation, the event handler should be used whenever a user is muted, deafened, leaves, or joins a channel.
However, even when I tried to get it to recognize those actions it gave me an error message of:
Ignoring exception in on_voice_state_update Traceback (most recent call last): File "C:\Users\Sam\PycharmProjects\FunBotProject\venv\lib\site-packages\discord\client.py", line 307, in _run_event yield from getattr(self, event)(*args, **kwargs) File "C:/Users/Sam/PycharmProjects/FunBotProject/my_bot2.py", line 63, in on_voice_state_update await client.say("Xd ") File "C:\Users\Sam\PycharmProjects\FunBotProject\venv\lib\site-packages\discord\ext\commands\bot.py", line 309, in _augmented_msg msg = yield from coro File "C:\Users\Sam\PycharmProjects\FunBotProject\venv\lib\site-packages\discord\client.py", line 1145, in send_message channel_id, guild_id = yield from self._resolve_destination(destination) File "C:\Users\Sam\PycharmProjects\FunBotProject\venv\lib\site-packages\discord\client.py", line 289, in _resolve_destination raise InvalidArgument(fmt.format(destination)) discord.errors.InvalidArgument: Destination must be Channel, PrivateChannel, User, or Object.

Sbrunner32 about 6 yearsThank you for the help trying to send the message, however I am still trying to figure out a way to use the on_voice_status_update in a way to determine only when a user joins a voice channel instead of when they leave, mute, or deafen themselves. Any help would be greatly appreciated.

Benjin about 6 yearsYou can check if the
before
has novoice_channel
and after has avoice_channel
. I've updated my answer to include this check
