【问题描述】:
我创建了这个音乐机器人,我想改进我的队列命令,因为它目前不是很实用。每次我排队一首歌曲我都必须使用播放命令来播放它,但我想自动播放下一首歌曲,在播放命令中实现队列命令也很酷,但我不知道如何去做吧。 可以帮忙吗?
youtube_dl.utils.bug_reports_message = lambda: ''
ytdl_format_options = {

if 'entries' in data:
# take first item from a playlist
data = data['entries'][0]

queue = []

global queue
queue.append(url)
await ctx.send(f'`{url}` added to queue!')
@client.command(name='play', help='This command plays songs')
async def play(ctx):
global queue
server = ctx.message.guild
voice_channel = server.voice_client
async with ctx.typing():
player = await YTDLSource.from_url(queue[0], loop=client.loop, stream=True)
voice_channel.play(player, after=lambda e: print('Player error: %s' % e) if e else None)
await ctx.send('**Now playing:** {}'.format(player.title))
del(queue[0])
编辑:所以我尝试做这样的事情但它不起作用,当我尝试使用 !play 当一首歌曲正在播放时它不会将它放入队列中,它说:ClientException: Already playing audio. 当这首歌完成了它说:TypeError: next() missing 2 required positional arguments: 'queue' and 'song'
这是代码:
queue = []
def next(client, queue, song):
if len(queue)>0:
new_song= queue[0]
del queue[0]
play(client, queue, new_song)
@bot.command()
async def join (ctx):
member = ctx.author
if not ctx.message.author.voice:
await ctx.send(f"{member.mention} You are not connected to a voice channel ❌")
else:
channel=ctx.message.author.voice.channel
await channel.connect()
@bot.command(help="This command plays a song.")
async def play (ctx,*args):
server = ctx.message.guild
voice_channel= server.voice_client
url=""
for word in args:
url+=word
url+=''
async with ctx.typing():
player = await YTDLSource.from_url(url ,loop=bot.loop, stream=True)
queue.append(player)
voice_channel.play (player, after=lambda e: next(ctx))
await ctx.send(f"**Now playing:** {player.title}")

-
this 回答你的问题了吗?
-
您可以尝试 OOP 方法并编写一个 Queue 类,这将提供更多功能/帮助。
-
我认为它可以工作,但我不知道如何在我的代码中实现它,因为我实际上是流式传输歌曲而不下载它,而且因为我是编程新手,所以我不知道该怎么做...@Mr_Spaar

不知道怎么办,能帮忙吗??? @Xiddoc。我一直在尝试@Mr_Spaar 方法,但我不知道如何实现它。
