Discord 音乐机器人不排队歌曲 (nextcord)

Question

当我使用play命令时，我的机器人不会排队歌曲，它只是播放它们。我试图在使用Spotify＆amp; bot中的soundcloud。我尝试排队歌曲，我无法排队。那么，有人可以帮我吗？我已经检查了wavelink文档，但找不到任何东西。（我是这个库的初学者）

代码：

import nextcord
from nextcord.ext import commands
import wavelink 
import random 
import datetime 
from datetime import datetime
import os

bot = commands.Bot(command_prefix=">")






@bot.event
async def on_wavelink_track_end(player:wavelink.Player,track:wavelink.Track,reason):
  ctx = player.ctx
  vc: player = ctx.voice_client
  
  if vc.loop:
    return await vc.play(track)

  next_song = vc.queue.get()
  await vc.play(next_song)
  emb = nextcord.Embed(description=f"Now playing {next_song.title}",color=nextcord.Color.magenta())
  emb.set_image(url=next_song.thumbnail)
  await ctx.send(embed=emb)   
  


@bot.command(aliases=["p"])
async def play(ctx,*,search:wavelink.YouTubeTrack):
  if not ctx.voice_client:
    vc: wavelink.Player = await ctx.author.voice.channel.connect(cls=wavelink.Player)
  elif not getattr(ctx.author.voice,"channel",None):
    embed=nextcord.Embed(description=f"{ctx.author.mention}: No song(s) are playing.",color=nextcord.Color.blue())
    return await ctx.send(embed=embed)

  
  
  else:
    vc:wavelink.Player = ctx.voice_client
  if vc.queue.is_empty and vc.is_playing:
   await vc.play(search)
   embe = nextcord.Embed(description=f"Now playing [{search.title}]({search.uri}) ",color=nextcord.Color.magenta())
  
   embe.set_image(url=search.thumbnail)
   await ctx.send(embed=embe)
  else:
    await vc.queue.put_wait(search)
    emb = nextcord.Embed(description=f"Added [{search.title}]({search.uri}) to the queue.",color=nextcord.Color.magenta())
  
    emb.set_image(url=search.thumbnail)
    await ctx.send(embed=emb)
  vc.ctx = ctx
  setattr(vc,"loop",False)
  


    
@bot.command()
async def queue(ctx):
  if not ctx.voice_client:
    vc: wavelink.Player = await ctx.author.voice.channel.connect(cls=wavelink.Player)
  elif not getattr(ctx.author.voice,"channel",None):
    embed=nextcord.Embed(description=f"{ctx.author.mention}: No song(s) are playing.",color=nextcord.Color.blue())
    return await ctx.send(embed=embed)
  
  else:  
     vc:wavelink.Player = ctx.voice_client

  if vc.queue.is_empty:
    emb = nextcord.Embed(description=f"{ctx.author.mention}: The queue is empty. Try adding songs.",color=nextcord.Color.red())
    return await ctx.send(embed=emb)
  lp = nextcord.Embed(title="Queue",color=nextcord.Color.blue())
  queue = vc.queue.copy()
  song_count = 0
  for song in queue:
    song_count += 1
    lp.add_field(name=f"[{song_count}] Song",value=f"{song.title}")
    return await ctx.send(embed=lp)




  

bot.run("TOKEN IS HERE JUST NOT LEAKING IT")

错误：

Traceback (most recent call last):
  File "/home/runner/Solved-Music/venv/lib/python3.8/site-packages/nextcord/client.py", line 417, in _run_event
    await coro(*args, **kwargs)
  File "main.py", line 181, in on_wavelink_track_end
    song_count += 1
  File "/home/runner/Solved-Music/venv/lib/python3.8/site-packages/wavelink/queue.py", line 212, in get
    raise QueueEmpty("No items in the queue.")
wavelink.errors.QueueEmpty: No items in the queue.

Answer 1

您需要将代码： vc:wavelink.Player = ctx.voice_client if vc.queue.is_empty and vc.is_playing: 更改为代码 vc:wavelink.Player = ctx.voice_client if vc.queue.is_empty 和**不是** vc.is_playing:

Answer 2

如果您遵循其他建议并将其添加到声明中。

if vc.queue.is_empty and not vc.is_playing:
   await vc.play(search)

在我的系统上，机器人会加载一首歌以添加到que并跳过

await vc.play(search)

它，因为我的系统和函数的原因：is_playing不要一起播放。

is_playing 

行

await vc.play(search)

始终返回正确，因此如果您有同样的问题，请跳过

if vc.queue.is_empty and vc.is_connected and vc._source is None:

    await vc.play(search)

：现在，您的机器人在使用Play命令时会播放，并且会排队未来的歌曲。
