问题描述

我正在尝试学习如何通过 discord.py 制作一个不和谐的机器人，并希望添加一个功能，即每当另一个用户加入机器人的语音频道时，都会从机器人发送消息目前在.我不知道如何使用事件处理程序本身，也没有充分了解他们的文档来使用它.

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")

根据我对文档的有限理解，只要用户静音、耳聋、离开或加入频道，就应该使用事件处理程序.

From my limited understanding of the documentation, the event handler should be used whenever a user is muted, deafened, leaves, or joins a channel.

但是，即使我试图让它识别这些操作，它也会给我一个错误消息:

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:UsersSamPycharmProjectsFunBotProjectvenvlibsite-packagesdiscordclient.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:UsersSamPycharmProjectsFunBotProjectvenvlibsite-packagesdiscordextcommandsot.py", line 309, in _augmented_msg
    msg = yield from coro

    channel_id, guild_id = yield from self._resolve_destination(destination)

    raise InvalidArgument(fmt.format(destination))
discord.errors.InvalidArgument: Destination must be Channel, PrivateChannel, User, or Object. Received NoneType

推荐答案

2020 年版本.请注意，我的代码在发送的消息方面表现不同.

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!")
