Good day, this is a concept maybe newbie question… what would be the best approach to develop the real time app… what I want is to be able to connect one device to other one within the app, and for example, if the app has a draggable object, then if one user drags the object, the other user see the object moving in real time I his own device, maybe using a ghost mode when interacting… this way both users using the app can interact with the objects in real-time. It’s not a game, so there’s no score… could I use gamecenter? or multipeer connectivity over BT? Is there a native framework? wich would be the easiest and less battery and system consuming approach someone could suggest? thank you in advance….
