Compared to writing the app once in Objective C and a 2nd time in Java with two divergent core SDK’s, Corona does make cross-platform easier. A zillion percent easier. But it’s never going to be 100% because the platforms themselves are different. Apple provides leaderboards/achievements, but the other guys don’t. OpenFeint was a nice cross-platform solution for them to use, but that’s no longer an option and there are really no other good choices right now. Having an online service to provide those feature’s is not the business that Corona Labs is in. They either have to have support from the platform or from 3rd party.
Game Minion is a good choice for this, but it doesn’t work with the existing Corona gamecenter type API calls, but they do provide a Lua/Corona module that works with Corona. You should check them out. [import]uid: 19626 topic_id: 31695 reply_id: 127840[/import]
