I am currently installing some modules for SDKBox.
I will report here some documentation bugs so maybe you can fix them.
SDKBox Play: http://docs.sdkbox.com/en/plugins/sdkboxplay/v3-cpp/
These 2 methods changed.
void onIncrementalAchievementStep( const std::string& achievement_name, int step );
void onScoreSubmitted( const std::string& leaderboard_name, int score, bool maxScoreAllTime, bool maxScoreWeek, bool maxScoreToday );
int step is now double
int score is now long
Also this link to the sample is wrong: http://docs.sdkbox.com/en/plugins/sdkboxplay/
That link is pointing to : https://github.com/sdkbox/obselete-sdkbox-SdkboxAds-sample instead of the right repository.
I will keep posting this bugs here or if you prefer I can send that bugs by email.
Thanks for the great work!
