        public void onPacketSending(PacketEvent event) {
            if (event.getPacketType() == PacketType.Play.Server.ENTITY_METADATA) {
                // Handle entity metadata packets
            } else if (event.getPacketType() == PacketType.Play.Server.ENTITY_EFFECT) {

    };

    // Register the packet listener
    protocolManager.addPacketListener(deathEffectsListener);

    getLogger().info("Untitled plugin has been enabled.");
}

@Override
public void onDisable() {
    // Unregister the packet listener
    if (protocolManager != null && deathEffectsListener != null) {

        getLogger().info("Packet listener has been removed.");
    }
