[C/C++]Gamemode SDK

[Dion ibe]

The GDK (Gamemode Development Kit a.k.a sampgdk) provides an API for developing SA-MP gamemodes in C or C++. Gamemodes written with GDK are no different from ordinary server plugins except that they make calls to an external library - the GDK runtime - that implements the core functionality, like SA-MP native functions, and can call you back if you want to handle certain SA-MP events (callbacks).

----------------------------------------------------------------------------------------------------------------

The structure of a GDK-based plugin is somewhat similar to that of a basic Pawn script:

----------------------------------------------------------------------------------------------------------------

*Pawn Code:

PLUGIN_EXPORT bool PLUGIN_CALL OnGameModeInit() {    SetGameModeText("Hello, World!");

    AddPlayerClass(0, 1958.3783f, 1343.1572f, 15.3746f, 269.1425f, 0, 0, 0, 0, 0, 0);

    ServerLog::Printf("------------------------------------------\n");
    ServerLog::Printf("      HelloWorld gamemode got loaded.     \n");
    ServerLog::Printf("------------------------------------------\n");

    SetTimer(1000, true, Timer, 0);

    return true;
}

PLUGIN_EXPORT bool PLUGIN_CALL OnPlayerConnect(int playerid) {
    SendClientMessage(playerid, 0xFFFFFFFF, "Welcome to the HelloWorld server!");
    return true;
}

PLUGIN_EXPORT bool PLUGIN_CALL OnPlayerRequestClass(int playerid, int classid) {
    SetPlayerPos(playerid, 1958.3783f, 1343.1572f, 15.3746f);
    SetPlayerCameraPos(playerid, 1958.3783f, 1343.1572f, 15.3746f);
    SetPlayerCameraLookAt(playerid, 1958.3783f, 1343.1572f, 15.3746f, CAMERA_CUT);
    return true;
}

PLUGIN_EXPORT bool PLUGIN_CALL OnPlayerCommandText(int playerid, const char *cmdtext) {
    if (std::strcmp(cmdtext, "/hello") == 0) {
        char name[MAX_PLAYER_NAME];
        GetPlayerName(playerid, name, MAX_PLAYER_NAME);
        char message[128];
        std::sprintf(message, "Hello, %s!", name);
        SendClientMessage(playerid, 0x00FF00FF, message);
        return true;
    }
    if (std::strcmp(cmdtext, "/pos") == 0) {
        float x, y, z;
        GetPlayerPos(playerid, &x, &y, &z);
        char message[128];
        std::sprintf(message, "You are at (%f, %f, %f)", x, y, z);
        SendClientMessage(playerid, 0xFFFFFFFF, message);
        return true;
    }
    return false;
}

Of course, since it's a plugin you'll need some additional boilerplate code (please consult the Plugin development guide for more details). Besides that you also have to perform some additional initialization and cleanup steps:

*Pawn Code:

static ThisPlugin helloworld;

PLUGIN_EXPORT bool PLUGIN_CALL Load(void **ppData) {
    helloworld.Load(ppData);
    return true;
}

PLUGIN_EXPORT void PLUGIN_CALL Unload() {
    helloworld.Unload();
}

Now if you are not planning to use timers you can stop at this point. Otherwise, there's one more thing left to do:

 

*Pawn Code:

PLUGIN_EXPORT void PLUGIN_CALL ProcessTick() {
    helloworld.ProcessTimers();
}

That's it!
