Packet API

1. Create a packet listener
2. Insert your own packet

Create a packet listener

//You can listen to a specific packet by its class name or by using the general Packet class
PacketLib.addHandler(new PacketHandler<PacketPlayOutChat>() {
   @Override
   public void handle(PacketHandleEvent<PacketPlayOutChat> e) {
      //You can cancel the event 
      e.setCanceled(true);
   }
});

WARNING: At the moment you can only register a Listener after the class PacketHandler has successfully loaded. This bug will be fixed in the future. If you register the Listener in the onEnable method you must register the listener delayed by one second.

Insert your own packet

//First argument is the Protocol. It can be HANDSHAKE, LOGIN, GAME, PING.
//Second argument is the target of the packet. Possibilities: TO_SERVER, TO_CLIENT
//Third argument is the packet id. List of all packets ids can you find here: http://wiki.vg/Protocol
//Fourth argument is the packet serializer class.
Packet.registerPacket(Protocol.TO_CLIENT, Direction, 1, <PacketClass>.class); //Register the serializer for the packet

Create the serializer class for the packet 0x1D (PacketPlayOutEntityEffect)
