GGZ Event hook function type, used as a vallback for events

typedef struct _GGZOptions GGZOptions¶

Options structure for ggzcore library

enum GGZGameEvent¶

A GGZGameEvent is an event associated with the game, that is triggered by a communication from the server or from the game. When a game event occurs, the associated event handle will be called, and will be passed the event data (a void*) along with the (optional) user data. All game events apply to the current game. Game events are usually triggered by calling ggzcore_server_read_data or ggzcore_game_read_data.

See also:

Enumeration values:

GGZ_GAME_LAUNCHED

A game was launched by the player (you). After this the core client should call ggzcore_game_get_control_fd, monitor the socket that function returns, and call ggzcore_game_read_data when there is data pending. This event is triggered inside of ggzcore_game_launch.

Parameters:

See also:

GGZ_GAME_LAUNCH_FAIL

Your game launch has failed. Triggered instead of GGZ_GAME_LAUNCHED when there's a failure somewhere.

Parameters:

See also:

GGZ_GAME_NEGOTIATED

Negotiation with server was successful. This should happen some time after the launch succeeds. The core client need do nothing at this point.

Parameters:

GGZ_GAME_NEGOTIATE_FAIL

Negotiation was not successful, game launch failed.

Todo

GGZ_GAME_PLAYING

Game reached the 'playing' state. When this happens the core client should call ggzcore_room_launch_table or ggzcore_room_join_table to finalize the game join.

Parameters:

enum GGZHookReturn¶

GGZ Hook function return types

Enumeration values:

GGZ_HOOK_OK

Success!

GGZ_HOOK_REMOVE

Remove this hook immediately.

GGZ_HOOK_ERROR

A localized error.

GGZ_HOOK_CRISIS

A major error; stop processing the event.

enum GGZLoginType¶

This controls the type of login a user chooses. A different value will require different information to be sent to the server.

Enumeration values:

GGZ_LOGIN

Standard login; uname and correct passwd needed.

GGZ_LOGIN_GUEST

Guest login; only a uname is required.

GGZ_LOGIN_NEW

New user login; only a uname is required. Password will be assigned by the server (but can be passed along).

enum GGZModuleEnvironment¶

The environment a game frontend expects.

Core clients should offer those game modules which fit their own environment.

Enumeration values:

GGZ_ENVIRONMENT_PASSIVE

No GUI, no interaction with user

GGZ_ENVIRONMENT_CONSOLE

Text console

GGZ_ENVIRONMENT_FRAMEBUFFER

VESA or framebuffer

GGZ_ENVIRONMENT_XWINDOW

X11 windowed mode (default)

GGZ_ENVIRONMENT_XFULLSCREEN

enum GGZOptionFlags¶

Enumeration values:

GGZ_OPT_MODULES

Load the default configuration file (unused).

GGZ_OPT_THREADED_IO

Load the game module list.

GGZ_OPT_EMBEDDED

Provide multi-threaded network IO (unused).

GGZ_OPT_RECONNECT

Reconnect automatically after connection loss.

enum GGZRoomEvent¶

A GGZRoomEvent is an event associated with the room, that is triggered by a communication from the server. When a room event occurs, the associated event handler will be called, and will be passed the event data (a void*), along with the (optional) user data. All room events apply to the current room unless a room number is given. Room events are almost always triggered by calling ggzcore_server_read_data.

See also:

Enumeration values:

GGZ_PLAYER_LIST

The list of players in a room has arrived.

Parameters:

Note:

See also:

GGZ_TABLE_LIST

Parameters:

enum GGZServerEvent¶

A GGZServerEvent is an event triggered by a communication from the server. Each time an event occurs, the associated event handler will be called, and will be passed the event data (a void*). Most events are generated as a result of ggzcore_server_read_data.

See also:

Enumeration values:

GGZ_CONNECTED

We have just made a connection to the server. After this point the server's socket should be accessible and should be monitored for data. It happens in direct response to ggzcore_server_connect. Note that most events after this will only happen by calling ggzcore_server_read_data on the server's FD!

Parameters:

See also:

GGZ_CONNECT_FAIL

Error: we have failed to connect to the server. This is generated in place of GGZ_CONNECTED if the connection could not be made. The server object is otherwise unaffected.

Parameters:

See also:

GGZ_NEGOTIATED

We have negotiated a connection to the server. This will happen automatically once a connection has been established, if the server socket is monitored.

Note:

Parameters:

See also:

GGZ_NEGOTIATE_FAIL

Error: negotiation failure. Could be the wrong version. This will happen in place of a GGZ_NEGOTIATED if the server could not be negotiated with.

Parameters:

See also:

GGZ_LOGGED_IN

We have successfully logged in. We can now start doing stuff. This will not happen until the client sends their login information.

See also:

Parameters:

See also:

GGZ_LOGIN_FAIL

Error: login failure. This will happen in place of GGZ_LOGGED_IN if the login failed. The server object will be otherwise unaffected.

Parameters:

See also:

GGZ_MOTD_LOADED

The MOTD has been read from the server and can be displayed. The server will send us the MOTD automatically after login; it can also be requested by ggzcore_server_motd. It is up to the client whether or not to display it. See the online documentation (somewhere?) about the MOTD markup format.

Parameters:

GGZ_ROOM_LIST

The room list arrived. This will only happen after the list is requested by ggzcore_server_list_rooms(). The list may be accessed through ggzcore_server_get_num_rooms() and ggzcore_server_get_nth_room(). Until this event arrives these functions will be useless!

Parameters:

See also:

GGZ_TYPE_LIST

The list of game types is available. This will only happen after the list is requested by ggzcore_server_list_types(). The list may be accessed through ggzcore_server_get_num_gametypes() and ggzcore_server_get_nth_gametype(). Until this event arrives these functions will be useless!

Parameters:

See also:

We have successfully entered a room. This will be issued to tell us a room join has succeeded, after it has been requested.

Parameters:

See also:

GGZ_ENTER_FAIL

Error: we have tried to enter a room and failed. This will be issued to tell us a room join has failed.

Parameters:

See also:

Parameters:

See also:

GGZ_NET_ERROR

Error: a network (transmission) error occurred. The server will automatically disconnect.

Parameters:

See also:

Parameters:

See also:

GGZ_CHANNEL_CONNECTED

Status event: a requested direct game connection has been established. To start a game (table), a channel must be created. This event will alert that the channel has been established. The channel's FD should then be monitored for input, which should then be passed back to the server object for handling.

Parameters:

Note:

See also:

GGZ_CHANNEL_READY

Game channel is ready for read/write operations. After the channel has been connected, if we continue to monitor the socket eventually it will be negotiated and ready to use. At this point it is ready for the game client to use.

Parameters:

Note:

See also:

GGZ_CHANNEL_FAIL

Error: Failure during setup of direct connection to game server. If the channel could not be prepared, this event will happen instead of GGZ_CHANNEL_READY or GGZ_CHANNEL_CONNECTED event. At this point the channel is no longer useful (I think).
