prime31 gamecenter plugin tutorial

i’ve bought the game center plugin yesterday and i’m new to unity and i’m very confused… i’m good in objective-c and i’ve done game center alot… but with this plugin there’s now (how to) there’s no neat document of how do i implement it … i built the app to xcode with the test scene they’ve provided on unity 3.5 and it gives me error message

EntryPointNotFoundException: _gameCenterRetrieveFriends

at (wrapper managed-to-native) GameCenterBinding:_gameCenterRetrieveFriends (bool)

at GameCenterBinding.retrieveFriends (Boolean loadProfileImages) [0x00000] in :0

at GameCenterGUIManager.OnGUI () [0x00000] in :0

(Filename: Line: -1)

and it can’t check if the gamecenter is available or not and it can’t authenticate … i spent alot of time try to figure out what the problem … i’ve put in unity the app identifier and everything is as what i did on the normal iphone apps … but always error with nothing happens… what the problem.

best regards,

Sounds like the post process script to integrate Prime31’s gamecenter plug-in didn’t run. Try deleting all assets related to the plug-in, reimport them, close XCode, and run it.

Other than that, what versions of Unity and XCode are you using? There were some post process problems between certain versions of each.
