DIscordpy Music bot-如何实现“跳过”命令？

Question

我制作了一个带有discordpy（ver 0.16.12）和youtube-dl的discord音乐支持机器人。我用asyncio模块制作了队列系统，但是我却陷于制作跳过系统。

此代码在python 3.5.4和3.6.8上运行，不和谐的模块版本为0.16.12。

play_next_song = asyncio.Event()
players = {}
links = {}
names = {}
m_players = asyncio.Queue()
m_links = []
m_names = []
np_link = ''
np_name = ''


async def player_task(id,ch) :
    global np_link
    global np_name
    while True :
        play_next_song.clear()
        np_name = names[id].pop(0)
        np_link = links[id].pop(0)
        current = await players[id].get()
        current.start()
        await app.send_message(ch, embed=discord.Embed(title=" Now playing : " + str(np_name),description='link : ' + str(np_link) ,color=0xC47EED))
        await play_next_song.wait()
        np_link = ''
        np_name = ''

def toggle_next() :
    app.loop.call_soon_threadsafe(play_next_song.set)

if message.content.startswith('~play https:') :
        url = message.content[6:]
        #await app.delete_message(message)
        server = message.server
        ch = message.channel
        links[server.id] = m_links

        if message.author.voice.voice_channel == None :
            await app.send_message(message.channel, embed=discord.Embed(title="⚠ Plz join in voice channel", color=0xC47EED))
        else :
            links[server.id].append(url)
            players[server.id] = m_players
            user_ch = message.author.voice.voice_channel
            voice_client = app.voice_client_in(server)

            if voice_client == None :
                voice = await app.join_voice_channel(user_ch)
            else :
                voice = voice_client

            player = await voice.create_ytdl_player(url,before_options="-reconnect 1 -reconnect_streamed 1 -reconnect_delay_max 2",after=toggle_next)
            await players[server.id].put(player)
            names[server.id] = m_names
            names[server.id].append(player.title)
            await app.send_message(message.channel, embed=discord.Embed(title="✅ Enqueued %s" %(player.title), color=0xC47EED))

            if np_name == '' :
                np_link = str(links[server.id][0])
                np_name = str(names[server.id][0])
                app.loop.create_task(player_task(server.id, ch))

if message.content == '~skip' :
        server = message.server
        ch = message.channel
        try :
            if app.loop.is_running() :
                app.loop.stop(player_task)
                app.loop.create_task(player_task(server.id, ch))
                embed=discord.Embed(title="✅ skip success!", color=0xC47EED)
        except :
            embed=discord.Embed(title="❎ skip failed!", color=0xC47EED)
        await app.send_message(message.channel, embed=embed)

我为在多个服务器上同时使用该机器人制作了一些字典变量。
