Hello, sorry maybe its an old question, but I’m new to Unity and app developing. Im in the process of developing a simple iPhone game and was wondering how do I make my game ready for GAME CENTER, is there a code that I need to add or I just check GAME CENTER on iTunes Connect?
Please help, THANK YOU!
