我尝试创建字典并将.create_ytdl_player()实例列表存储到每个discord服务器ID。
我只需要知道如何在前一个玩家完成之后让玩家玩。
我想我必须使用.is_playing()或.is_done(),但我不知道如何使用它们。有人可以帮忙吗?

我将使用适用于单个实例的代码回答问题(尽管通过从字典中提取正确的播放器和voice_channel对象来编辑多个实例并不困难)。
你必须首先建立一个队列来存储你的播放器将播放你的对象的网址。我假设你还应该制作一个队列字典来存储不同服务器的不同网址。
要帮助管理您的stream_player工作流程,请先在最外层范围内声明语音和播放器对象。
self.player = None
self.voice = None
应在机器人加入语音通道后设置语音对象:
mvoice = await client.join_voice_channel(voice channel id here)
self.voice = mvoice
然后我们必须创建两个函数,因为Python不支持异步lamdas,而管理流播放器只能通过异步函数完成。每当用户键入相关命令时,bot应该调用play_music函数:
#pass the url into here when a user calls the bot
async def play_music(client, message, url=None):
if url is None:
#function is being called from after (this will be explained in the next function)
if queue.size() > 0:
#fetch from queue
url = queue.dequeue()
else:
#Unset stored objects, also possibly disconnect from voice channel here
self.player = None
self.voice = None
return
if self.player is None:
#no one is using the stream player, we can start playback immediately
self.player = await self.voice.create_ytdl_player(url, after=lambda: play_next(client, message))
self.player.start()
else:
if self.player.is_playing():
#called by the user to add a song
queue.enqueue(url)
else:
#this section happens when a song has finished, we play the next song here
self.player = await self.voice.create_ytdl_player(url, after=lambda: play_next(client, message))
self.player.start()
在流播放器完成一首歌之后,将从终结器调用play_next函数,并且将再次调用上述函数但没有url参数。
def play_next(client, message):
asyncio.run_coroutine_threadsafe(play_music(client, message), client.loop)
