The messages are arbitrary blocks + of data, of an arbitrary length. + This layer is an underlying protocol that isn't game specific at all. + You shouldn't need to know the message format of the packets. If you + want to extend the protocol, have a look into KMessageServer API + reference for a complete list of message types. + + - the game layer (KGame, KGameIO, KPlayer) + + This layer uses the message layer to send its specific message packets + between the objects of the game. + This layer contains the game specific messages (e.g. addPlayer, setupGame). + The rest of this file describes this layer. + + +Game Layer Messages: +-------------------- + + Application Cookie 16 Bit + Version 8 Bit + MsgId 16 Bit + SenderId 16 Bit + ReceiverId 16 Bit + Userdata + +The format of the messages is used internally and there is usually no reason why +you have to know what it is used for.

So we get +Id=playerId | (gameId<<10); +ReceiverId is the id of the receiver of the message. It can be either +a player, a game or a broadcast.
