[1.7.10][Solved]@a in a custom command works only in singleplayer

[Filloax]

Hello, I'm trying to make an improved playsound command. I got the packet etc working, only problem is that @a works only when there is one player in LAn or in singleplayer (couldn't test with proper server, but I imagine it's the same). When I try to use the command with @a when tehre are 2 players in LAN, it says "That player cannot be foundr"

 

The only thing different form /playsound with player seems that playsound uses entityplayermp.playerNetServerHandler.sendPacket while I use network.sendTo

 

Code:

In command class:
public void processCommand(ICommandSender player, String[] input)
    {
        if (input.length < 1)
        {
            throw new WrongUsageException(this.getCommandUsage(player), new Object[0]);
        }
        else
        {
        	String sound = input[0];
        	String mode = "normal";
            int x = player.getPlayerCoordinates().posX;
            int y = player.getPlayerCoordinates().posY;
            int z = player.getPlayerCoordinates().posZ;
            float vol = 1;
            float pitch = 1;
            EntityPlayerMP playerarg = getPlayer(player, "@a");
            
            World world = player.getEntityWorld();
            if (input.length > 1) {
            	mode = input[1];
            }
            if (input.length > 2) {
            	playerarg = getPlayer(player, input[2]);
            }
            if (input.length > 5) {
            	x = MathHelper.floor_double(func_110666_a(player, (double)x, input[3]));
                y = MathHelper.floor_double(func_110666_a(player, (double)y, input[4]));
                z = MathHelper.floor_double(func_110666_a(player, (double)z, input[5]));
            }
            if (input.length > 6) {
            	vol = Float.parseFloat(input[6]);
            }
            if (input.length > 7) {
            	pitch = Float.parseFloat(input[7]);
            }

            Main.network.sendTo(new SoundPacket(sound, mode, x, y, z, vol, pitch), playerarg);
            
            System.out.println("Played \'"+sound+"\' to \'"+playerarg.getDisplayName()+"\' at "+x+" "+y+" "+z);
        }

In packet handler:

	@Override
	public IMessage onMessage(SoundPacket m, MessageContext ctx) {
		System.out.println(m.sound+";"+m.mode+";"+m.x+";"+m.y+";"+m.z+";"+m.vol+";"+m.pitch);
    	
		ChunkCoordinates chunkcoordinates = new ChunkCoordinates(m.x, m.y, m.z);
    	ISound isound = mapSoundPositions.get(chunkcoordinates);
    	System.out.println("isound get");
    	if (isound != null) {
    		System.out.println("Sound already playing at " + m.x + "/" + m.y + "/" + m.z + "; stopping sound");
    		Minecraft.getMinecraft().getSoundHandler().stopSound(isound);
    		mapSoundPositions.remove(chunkcoordinates);
    	}
    	if (m.mode.equals("normal")) {
    		System.out.println("Playing sound at " + m.x + "/" + m.y + "/" + m.z + ": " + m.sound);
    		ResourceLocation resource = new ResourceLocation(m.sound);
    		PositionedSoundRecord psr = new PositionedSoundRecord(resource, m.vol, m.pitch, m.x, m.y, m.z);
    		mapSoundPositions.put(chunkcoordinates, psr);
    		Minecraft.getMinecraft().getSoundHandler().playSound(psr);
    	}
		return null;
	}

Solved, apparently I needed to specify wich arg wasa the username in the isUsernameIndex function. Second time I post an issue which I solve myself today, lol
