discord.py - 在音乐机器人上添加 queue 以解决不和谐和搜索问题
discord.py - Adding a queue on a music bot for discord and search problems
有 2 个问题。
首先，我尝试为 discord 制作一个音乐机器人，它运行良好，直到我尝试从中播放另一首歌曲，播放另一首歌曲（queue 也许？）我不得不离开机器人语音通道并再次编写播放命令（这不是我想要的）并且还尝试从音乐标题播放而不是仅从 url 播放（因为转到 youtube 并复制 link 对于我想播放的每首歌）但只有当我把标题放在下划线之间时它才有效（比如“！播放 name_of_the_song”）我尝试了很多东西但是 none 似乎有效, 所以在这里问是我最后的火腿。
所以我想要的是通过播放命令一首又一首地播放机器人，并且我可以从它的标题中搜索一首歌，而不给我另一首与我正在寻找的东西无关的歌曲
我的代码现在是什么样的：

可以为公会排队播放音乐。使用内置模块队列，或仅使用列表。像这样的东西会起作用：
queue = {}
def addToQueue(guild, song):
if guild.id in queue:
queue[guild.id] = []
queue[guild.id].append(song)
async def playSong(ctx, channel):
async with ctx.typing():
song = queue[channel.guild.id].pop(0, None)
if song == None:
return
player = await YTDLSource.from_url(song, loop=client.loop, stream=True)
channel.play(
player,
after=lambda e:
print('Player error: %s' % e) if e else await playSong(ctx, channel)
)
await ctx.send('**Now playing:** {}'.format(player.title))
@client.command(name='play', help='This command plays music')
async def play(ctx, url):
if not ctx.message.author.voice:
await ctx.send("You are not connected to a voice channel")
return
else:
channel = ctx.message.author.voice.channel
voice = discord.utils.get(client.voice_clients, guild=ctx.guild)
if channel != voice and voice is None:
await channel.connect()
elif channel != voice and voice is not None:
await ctx.send("Already connected to a channel")
return
server = ctx.message.guild
voice_channel = server.voice_client
addToQueue(ctx.message.guild, url)
await playSong(ctx, voice_channel)
对于您的搜索问题，您提供的代码似乎无法解决该问题。您将不得不使用 Youtube API。
