Detailed Description
The KGameNetwork class is the KGame class with network support. The main KDE game object.All other features are the same but they are now network transparent. It is not used directly but only via a KGame object. So you do not really have to bother with this object.

Is this the game MASTER (i.e. has started theKMessageServer). A game has always exactly one MASTER. This is either a KGame object (i.e. a Client) or an own MessageServer-process. A KGame object that has the MASTER status is always admin. You probably don't want to use this. It is a mostly internal method which will probably become protected. Better use isAdmin

|
The admin of a game is the one who initializes newly connected clients using negotiateNetworkGame and is allowed to configure the game. E.g. only the admin is allowed to use KGame::setMaxPlayers. If one KGame object in the game is MASTER then this client is the admin as well. isMaster and isAdmin differ only if the KMessageServer is running in an own process.

Inits a network game as network MASTER. Note that if the KMessageServer is not yet started it will be started here (see setMaster). Any existing connection will be disconnected. If you already offer connections the port is changed.

|
Changes the maximal connection number of the KMessageServer to max. -1 Means infinite connections are possible. Note that existing connections are not affected, so even if you set this to 0 in a running game no client is being disconnected. You can call this only if you are the ADMIN!
Definition at line 315 of file kgamenetwork.cpp. References isAdmin(). |
|
Sends a network message msg with a given msg id msgid to all clients. Use this to communicate with KGame (e.g. to add a player ot to configure the game - usually not necessary). For your own messages use sendMessage instead! This is mostly internal!

Send a network message msg with a given message ID msgid to all clients. You want to use this to send a message to the clients. Note that a message is always sent to ALL clients! This is necessary so that all clients always have the same data and can easily be changed from network to non-network without restarting the game. If you want a specific KGame / KPlayer to react to the message use the receiver and sender parameters. See KGameMessage::calsMessageId SendMessage differs from sendSystemMessage only by the msgid parameter. sendSystemMessage is thought as a KGame only mehtod while sendMessage is for public use. The msgid parameter will be +=KGameMessage::IdUser and in KGame::signalNetworkData msgid will be -= KGameMessage::IdUser again, so that one can easily distinguish between system and user messages. Use sendSystemMessage to comunicate with KGame (e.g. by adding a player) and sendMessage for your own user message. Note: a player should send messages through a KGameIO!

If you are the ADMIN of the game you can give the ADMIN status away to another client. Use this e.g. if you want to quit the game or if you want another client to administrate the game (note that disconnect calls this automatically).

This signal is emitted whenever the KMessageServer sends us a message that a new client connected. KGame uses this to call KGame::negotiateNetworkGame for the newly connected client if we are admin (see isAdmin)

Called by KMessageClient::broadcastReceived() and will check if the message format is valid. If it is not, it will generate an error (see signalNetworkVersionError and signalNetworkErorrMessage). If it is valid, the pure virtual method networkTransmission() is called. (This one is overwritten in KGame.)
