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 File "C:UsersSamPycharmProjectsFunBotProjectvenvlibsite-packagesdiscordclient.py", line 1145, in send_message channel_id, guild_id = yield from self._resolve_destination(destination) File "C:UsersSamPycharmProjectsFunBotProjectvenvlibsite-packagesdiscordclient.py", line 289, in _resolve_destination raise InvalidArgument(fmt.format(destination)) discord.errors.InvalidArgument: Destination must be Channel, PrivateChannel, User, or Object.

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!")
