Discord音乐机器人-队列（Discord.py）

Question

我是一个初学者程序员（或者在我看来是这样），我需要帮助在音乐机器人中实现一个队列。

目前，只有当队列中有一首歌时，队列才能正常工作。如果有更多的歌曲，那么递归开始（在=wait serverQueue（语音，消息）之后从def play开始并等待play（queue.pop（0），语音，消息）从队列开始），并且所有歌曲只是跳过。

import discord
import nacl
import ffmpeg
from discord import FFmpegPCMAudio
from discord.utils import get
from youtube_dl import YoutubeDL

client = discord.Client()

async def join(message):
    ##Connect to channel
    connection = message.author.guild.voice_client
    idUserChannel = message.author.voice.channel.id
    idBotChannel = 0
    if connection:
        idBotChannel = client.voice_clients[0].channel.id
    if (connection) and (idBotChannel != idUserChannel) :
        await message.channel.send('**Moving to** ' + str(message.author.voice.channel))
        await connection.move_to(message.author.voice.channel)
    elif (idBotChannel != idUserChannel):
        await message.channel.send('**Connect to** ' + str(message.author.voice.channel))
        await message.author.voice.channel.connect()
        
async def play(video_link, voice, message):
    ##Playing songs
    ydl_opts = {'format': 'bestaudio', 'noplaylist':'True'}
    FFMPEG_OPTIONS = {'before_options': '-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 5', 'options': '-vn'}
    with YoutubeDL(ydl_opts) as ydl:
        info = ydl.extract_info(video_link, download = False)
    print(info.get('title'))
    URL = info['formats'][0]['url']
    print(URL)
    voice.play(FFmpegPCMAudio(URL, **FFMPEG_OPTIONS), after = await serverQueue(voice, message))
    voice.is_playing()
    await message.channel.send('**Now playing** - ' + info.get('title'))

async def skip(voice, message):
    ##Skip
    voice.stop()
    await serverQueue(voice, message)
    await message.channel.send('**Successfully skiped** - ' + info.get('title'))
    
##Queue
queue = []
async def serverQueue(voice, message):
    if queue != [] and not voice.is_playing():
        await play(queue.pop(0), voice, message)
        print('queue - ' + str(queue))

@client.event
async def on_message(message):
    if message.author == client.user:
        return
        
    if message.content.startswith('&' + 'join'):
        await join(message)
        
    ##Connect and play
    if message.content.startswith('&' + 'play'):
        await join(message)
        voice = get(client.voice_clients, guild = message.channel.guild)
        msg = message.content[1:].split()
        video_link = msg[1]
        if not voice.is_playing():
            await play(video_link, voice, message)
        else:
            await message.channel.send('Added to queue successfully')
            queue.append(video_link)

    ##Skip
    if message.content.startswith('&' + 'skip'):
        voice = get(client.voice_clients, guild = message.channel.guild)
        await skip(voice, message)

我试图以不同的方式解决这个问题，例如，引入了第二个变量，但这并没有带来成功。如果有任何帮助，我将不胜感激。
