• Need help to create a queue system with a discord.py bot

  19 août 2024, par Zamv

  im trying to create a bot with discord.py, i'll start saying that the bot is for personal use so please don't point out that i shouldn't use ydl in the comments, ty :
Also, im a beginner, so please tell me what I can improve and any errors there are, I will be happy to listen.
That said, i've been stuck on trying to create this queue system for songs for the past 3 days, the bot was working perfectly fine and played some urls before i implemented the play_next function, now it doesn't even play the first song, even if it sends confirmation messages both in the terminal that in the discord channel, i know that the code might be a little confusing, but please i really need to know how to make this work

  


  i wrote two main functions : "play_next" to play the next song in the queue and "play", the main command.
Here is my play_next function :

  


  async def play_next(self,ctx):
        if not ctx.voice_client.is_playing: #(don't know if this is correct as I also check if the bot isn't                     playing anything in the play function)
            
            if self.song.queue: 
                next_song = self.song_queue.pop(0) #deleting the first element of the queue, so if we have (song_0, song_1 and song_2) the bot should delete (song_0) making in fact song_1 the "next" song_0
                try:
                    ctx.voice_client.play(discord.FFmpegPCMAudio(next_song), 
                                          after=lambda e: self.bot.loop.create_task(self.play_next(ctx))) #Not gonna lie here, i asked chat gpt for this line, it should make the bot automatically play the next song one after another, correct me if I am wrong

#this is not important
                    embed = discord.Embed(
                        title="Song",
                        description=f"Now playing {next_song}",
                        color = 0x1DB954
                    )
                    await ctx.send(embed=embed)
                except Exception as e:
                    print(f"Error playing the next song: {e}")

            else:
                await ctx.voice_client.disconnect()  # disconnecting from the voice channel if the queue is empty
                print("Disconnected from the voice channel as the queue is empty.")


  


  I think that the main problem of my bot is the play_next function, but here it is my "play" function :

  


      @commands.command(pass_context=True)
    async def play(self, ctx, url: str):  
        if ctx.author.voice:  # first checking if the user is in a voice channel
            if not ctx.voice_client: #then checking if the bot is already connected to a voice channel
                channel = ctx.message.author.voice.channel 
                try:
                    await channel.connect()  #then joining
                    print("I joined the voice channel!")
                except Exception as e:
                    print(f"Failed to connect to the voice channel: {e}")
                    return

            song_path = f"song_{self.song_index}.mp3" #note, im using cogs, i declared self.song_index with the value of 0 
            self.song_index += 1 #i thought that this was the easiest way of creating a new file for each song

            ydl_opts = {
                'format': 'bestaudio/best',
                'postprocesors': [{
                    'key': 'FFmpegExtractAudio',
                    'preferredcodec': 'mp3',
                    'preferredquality': '192',
                }],
                'outtmpl': song_path
            }
            try:
                with youtube_dl.YoutubeDL(ydl_opts) as ydl:
                    print("Starting download...")
                    ydl.download([url]) #this is where it should download the song provided by the url
                    print("Download finished.")
            except Exception as e:
                await ctx.send(f"Failed to download the song: {e}")
                return

#i think that the next two if statements are the main threats
            if os.path.exists(song_path): #if there is atleast 1 song in the queue
                self.song_queue.append(song_path) #append the next one
                embed = discord.Embed(
                    title="Added to Queue!",
                    description = f"{url} has been added to the queue.",
                    color=0x33ff33
                )
                await ctx.send(embed=embed)


                if not ctx.voice_client.is_playing(): #checking if the bot is already playing something, don't know if i should put this if statement here
                    print("Starting playback...")
                    await self.play_next(ctx) #if nothing is playing, then the bot should play the next song



            else:
                await ctx.send("Failed to download or find the audio file.")

        else:
            embed = discord.Embed(
                title="❌You must be in a voice channel",
                color=0xff6666
            )
            await ctx.send(embed=embed)


  


  thanks in advance, i will try to read and answer any questions as soon as possible

  


• Issues with Discord JS Music Bot

  5 décembre 2020, par Thresio

  I am in the process of creating a Discord bot with JS, giving it management, auto role, etc. I just got to the music section of it and I can't quite figure out whats wrong.

  



  I believe I have installed FFmpeg correctly, as I have access to it from within the terminal. I have also used npm to bring ytdl-core and opusscript into my program.

  



  What this should do is make the bot join the chat, then play the Youtube link. Currently, I am not error checking the second argument as I just wanted to get it working initially. I have implemented several different instances of .toString() and String() however it always gives the same error listed below.

  



  . The program still throws this error :

  



  TypeError [ERR_INVALID_ARG_TYPE]: The "file" argument must be of type string. Received type object
TypeError [ERR_INVALID_ARG_TYPE]: The "file" argument must be of type string. Received type object

  Here is my code for calling play :

  



  case 'play':

            function play(connection, message){
                var server = servers[message.guild.id];

                server.dispatcher = connection.playStream(ytdl(server.queue[0], {filter: 'audioonly'}));

                server.queue.shift();

                server.dispatcher.on('end', function(){
                    if(server.queue[0]){
                        play(connection, message);
                    }else {
                        connection.disconnect();
                    }
                })
            }

            if(!args[1]){
                message.channel.send('You need to provide a link!');
                return;
            }

            if(!message.member.voiceChannel){
                message.channel.send('You must be in a voice channel to play music!');
                return;
            }

            if(!servers[message.guild.id]) servers[message.guild.id] = {
                queue: []
            }

            var server = servers[message.guild.id];

            server.queue.push(args[1]);

            if(!message.guild.voiceConnection) message.member.voiceChannel.join().then(function(connection){
                play(connection, message);
            })
            break;


  



  If anyone could assist with this, I would be very grateful.

  



  EDIT : I unfortunately never figured out my main issue, but I have now found code that works (unlike mine :/).
For anyone else having this issue, I suggest using the code found here.
Works like a charm !
