I'd like to have a way to read/write the number of coins that the current user has, the reason is that I want to give the user the option to "spend" those coins in digital assets that are not in the game. Is that posible without accessing the underlying Cocos scene and data? If I need to access the Cocos scene I'd like to know how to do it since I tried to recompile the main.cpp file in a project exported with version 2.2.9 but it seems it needs the cocos2dx libraries, but the project doesn't have have those .so files.
