英文:
In my discord bot ctx.author.voice.channel is not returning any value
问题
异步 def play(self, ctx, *args):
query = " ".join(args)
voice_channel = ctx.author.voice.channel
print(voice_channel)
if voice_channel is None:
print('测试')
#需要连接才能让机器人知道要去哪里
# await message.channel.send(response)
await ctx.send("连接到语音频道！")
elif self.is_paused:
print('poop')
self.vc.resume()
else:
print('你好')
song = self.search_yt(query)
if type(song) == type(True):
await ctx.send("无法下载歌曲。请尝试其他关键字，可能是播放列表或直播流格式错误。")
else:
await ctx.send("歌曲已添加到队列")
self.music_queue.append([song, voice_channel])
if self.is_playing == False:
await self.play_music(ctx)
英文:
I want my discord bot to send me a message if there is no one in a voice channel.
async def play(self, ctx, *args):
query = " ".join(args)
voice_channel = ctx.author.voice.channel
print(voice_channel)
if voice_channel is None:
print('test')
#you need to be connected so that the bot knows where to go
# await message.channel.send(response)
await ctx.send("Connect to a voice channel!")
elif self.is_paused:
print('poop')
self.vc.resume()
else:
print('hello')
song = self.search_yt(query)
if type(song) == type(True):
await ctx.send("Could not download the song. Incorrect format try another keyword. This could be due to playlist or a livestream format.")
else:
await ctx.send("Song added to the queue")
self.music_queue.append([song, voice_channel])
if self.is_playing == False:
await self.play_music(ctx)
However, if I'm not in the voice channel, nothing gets returned. If I do print(voice_channel) literally nothing shows up in my linux terminal, not even a None value. Any thoughts here?

因为如果你不在语音频道中，ctx.author.voice 将为 None。然后，None.channel 将导致未捕获的异常，即 NoneType 对象没有属性。<br>
要检查命令作者是否在频道中，可以考虑检查其 voice 属性，类似于以下方式：
voice = ctx.author.voice
if voice is None: # 作者不在语音频道中
# 进行一些操作，比如告诉作者应该加入语音频道，然后返回
return
# 这意味着作者已加入语音频道
print(voice.channel) # 获取作者的频道
此外，如果你想检查音乐是否正在播放，需要访问你的机器人 voice_client，而不是命令作者（用户）的 voice_client。你可以像这样进行操作：
bot_voice = ctx.voice_client # 快捷方式到 ctx.guild.voice_client
if bot_voice and bot_voice.is_paused(): # 机器人连接到频道且音乐已暂停
bot_voice.resume()
elif ... : # 可能检查 voice 并执行一些连接操作
英文:
Because if you are not in the voice channel, ctx.author.voice will be None. Then, None.channel will lead to an uncaught exception, which is NoneType Object has no attribute. <br>
To check whether command author is in the channel or not. Consider checking its voice, sth like
voice = ctx.author.voice
if voice is None: # author is not in the voice channel
# do sth like telling author should join a voice channel and return
return
# it means author joins a voice channel
print(voice.channel) # to get the author's channel
Also, if you want to check whether the music is still playing or not. You need to access your bot voice_client, not the command author (which is the user)'s voice_client. You could do sth like:
bot_voice = ctx.voice_client # shortcut to ctx.guild.voice_client
if bot_voice and bot_voice.is_paused(): # bot connects to a channel and music is paused
bot_voice.resume()
elif ... : # maybe check voice and do some connection stuff
