Can anyone give me an advise about a tool that allows me to enable social features into my game?
I want a tool like OpenFeint. But I prefer that have a C++ API.


Game Center

If you’re on ios, that’s easy to invoke OpenFeint objc interface from .mm file, you can reference to “how to play video in cocos2d-x games”, google these keywords or find it on this forum.
If you’re on android, you had to invoke OpenFeint from JNI layer, several works to do.


I think that I can use web access to OpenFeint.


What do you think?


I find a company that have this service totally free:

I can use this through a C API




First you need to add ggc-sdk to your project.

Then to add Gammeta to your game:
extern “C”
#include “ggc.h”
#include “utils.h”

To send score to Gammeta:
const char* game_id = “853245345345729”;
const char* test_key = faGefShrHSasJMohClh2UFT1kE“;
const char* player = pTextField->getString();
const char* email =”“;
unsigned int points = score;
char player_hash[32] = {0};
char salt_source[255] = {0};
sha1_base64(email, player_hash);
sprintf(salt_source,”s\nu\n%s“, player, points, player_hash);
ggc_init(&context, GGC_SERVICE_SLS, game_id);
ggc_set_headers(&context,”SDK/C“, test_key, salt_source, TRUE);

To get sorted list of scores:
const char* game_id =”853245345345729“;
const char* test_key = faGefShrHSasJMohClh2UFT1kE”;
json_object_t* json_result;
GGC_CTX context;
ggc_init(&context, GGC_SERVICE_SLS, game_id);
ggc_set_headers(&context, “SDK/C”, test_key, NULL, TRUE);
json_result = ggc_sls_get_world_scores(&context);

Result of get_world_scores:

[ { AchievedAt “2011-06-12 12:44:03Z”, CountryCode “EC”, PlayerHash “h6w\/lzj\/lv6efqltxcyj68hnc6y=”, PlayerName “gorgak”, Points 8646, Region “Azuay”, Tags [ “UserAgent:SDK\/C” ], WorldRank 1 },

As you can see Gammeta save your Country, Region, Tags, Player name, Points, WorldRank, and optionally your geolocation.

Fun with Gammeta!

PD: this post is to use Gammeta on test mode, to use on live mode you need a SLS subscription, use your live key and set FALSE on ggc_set_headers
ggc_set_headers(&context, “SDK/C”, test_key, NULL, FALSE);

On windows and android for use live mode you need to change, because libcurl cocos2d-x integrated library seems dont have zlib support


Awesome! Thanks Diego!

I’m getting ready to launch Gammeta in public beta in a few weeks. Working on a brand new website, which is why the old one is down for the moment. Stay tuned!



oh my god, the author of Gammeta appears here, cool! #CCHandshake
