Constructor & Destructor Documentation

GameEventsProtocol()

GameEventsProtocol::GameEventsProtocol

(

)

This class handles all 'major' game events.

E.g. finishing a race or goal etc. The game events manager is notified from the game code, and it calls the corresponding function in this class. The server then notifies all clients. Clients receive the message in the synchronous notifyEvent function here, decode the message and call the original game code. The functions name are identical, e.g. kartFinishedRace(some parameter) is called from the GameEventManager on the server, and the received message is then handled by kartFinishedRace(const NetworkString &).

Member Function Documentation

asynchronousUpdate()

virtual void GameEventsProtocol::asynchronousUpdate ( )

inlinevirtual

Called by the protocol listener as often as possible.

Must be re-defined.

Implements Protocol.

kartFinishedRace() [1/2]

void GameEventsProtocol::kartFinishedRace	(	AbstractKart *	kart,
		float	time
	)

This function is called from the server when a kart finishes a race.

It sends a notification to all clients about this event.

Parameters

kart	The kart that finished the race.
time	The time at which the kart finished.

kartFinishedRace() [2/2]

void GameEventsProtocol::kartFinishedRace

(

const NetworkString &

ns

)

This function is called on a client when it receives a kartFinishedRace event from the server.

It updates the game with this information.

Parameters

ns	The message from the server.

notifyEvent()

bool GameEventsProtocol::notifyEvent ( Event *  event )

virtual

Notify a protocol matching the Event type of that event.

Parameters

event

: Pointer to the event.

Returns

True if the event has been treated, false otherwise.

Reimplemented from Protocol.

notifyEventAsynchronous()

virtual bool GameEventsProtocol::notifyEventAsynchronous ( Event *  event )

inlinevirtual

Notify a protocol matching the Event type of that event.

This update is done asynchronously :

Parameters

event

: Pointer to the event.

Returns

True if the event has been treated, false otherwise

Reimplemented from Protocol.

setup()

virtual void GameEventsProtocol::setup ( )

inlinevirtual

Called when the protocol is going to start.

Must be re-defined by subclasses.

Implements Protocol.

update()

void GameEventsProtocol::update ( int  ticks )

virtual

Called by the protocol listener, synchronously with the main loop.

Must be re-defined.

Implements Protocol.
