Creating new Packet

Don't panic if a new version of Minecraft with new packets is released. Adding new packets is very simple. Just mark is as IPacket and implement Id, ReadPacket and WritePacket

public struct YourPacket : IPacket
    {
        public *put here used objects*

        public const byte PacketId = *Packet Id*;
        public byte Id { get { return *Packet Id*; } }

        public void ReadPacket(ref Wrapped stream)
        {
            *Read here your objects*
        }

        public void WritePacket(ref Wrapped stream)
        {
            stream.WriteVarInt(Id);
            *Write here your objects*
            stream.Purge();
        }
    }

Don't forget to add it in PacketResponse.cs in used section (Login, Status or Play) (position is important, put it in right place, see commented hex) for reading it from server.
