Solved ProtocolLib - Disable a sound.

Problem is I can still here the sound play.

CODE:

Code:

ProtocolLibrary.getProtocolManager().addPacketListener(
  new PacketAdapter(this, ListenerPriority.NORMAL,
          PacketType.Play.Server.NAMED_SOUND_EFFECT) {
                    @Override
                    public void onPacketSending(PacketEvent event) {
                        PacketContainer packet = event.getPacket();
                        String soundName = packet.getStrings().read(0);
                        if (ProtocolLibrary.getProtocolManager().getProtocolVersion(event.getPlayer()) <= 47) {
                            if (soundName.equalsIgnoreCase("random.levelup")) {
                                event.setCancelled(true);
                            } else if (ProtocolLibrary.getProtocolManager()
                                    .getProtocolVersion(event.getPlayer()) >= 107) {
                                if (soundName.equalsIgnoreCase("entity.player.levelup")) {
                                    event.setCancelled(true);
                                }
                            }
                        }
                    }
                });

Checking what version the client is on then if they are less than or equal to 47 then they are either on 1.8, 1.7 or below but I have it only 1.7 - 1.10.2. Then checked if they were greater than or equal to 107 if so then the sound name was 1.9 - 1.10.2+.

If you could help me out that'd be much appreciated.

 

This says there are no strings for the packet.

This is what is causing the error.

Before 1.8, you could only play existing sounds. That means that there was a static set of values for each sound. I would recommend using an older server version/P.L and test out what the old parameters were.

 

@Zombie_Striker in ProtoclLib it's getSoundEffects my issue is solved.
