Hi, I'm following the tutorial to implement Game Center in an app. Having some issues. First, on page 10 of the tutorial, it tells me to find "//scoreboard button shows if we have it on and if a scoreboard URL is provided". i dont seem to have this point in my BT_screen_quiz.m file. Unable to do this point, when I try to build, I get some errors Errors in BT_viewControllerManager.h - on BT viewcontrollermanager.h, cannot find protocol declaratio for ADBannerViewdelegate Errors in BT_viewControllerManager.m - Use of undeclared identifier GKLeaderboardID, did you mean GKLeaderboard? Errors in BT_screen_quiz.m - Use of undeclared identifier submitscore -@implementation BT_screen_quiz - incomplete implementation On page of the 5 of the tutorial, I see "then add the following to the @interface so it looks like this... I see @interface BT_viewController..... If I use this I get dozens os errors, if instead I use BT_viewcontrollerManager, I get the errors above. Can anyone point me in the right direction? My programing knowledge is almost zero. Thank you

I have implemented Game Center successfully twice now. The line on page 10 is there. Try [cmd + f] then type in "//scoreboard button shows" and it will locate the line if its there and it should be. Make sure you have the code copied correctly for page 5, its easy to miss a ',' or something. Hope this helps.

Thank you. I did what you said, but did not find those lines... I'm using the quiz plugin recently added by BT for self hosted. Is that what you used? On page 5 should I use BT_viewController or BT_viewcontrollerManager? Thank you

Please ignore my answer, let me re-check everything.

Ok, double checked everything, I had some errors, corrected. Have one still remaining. In BT_screen_quiz.m I have: - Use of undeclared identifier submitscore here: Above “//show quiz reward screen” Add: //submit score -(void)submitScore{ if(totalPoints > 0) Any idea?

Hey, so I fixed that too, was typeing it a few lines above of where I should type. Did a search in the complete project, did not find "//scoreboard button shows if we have it on and if a scoreboard URL is provided" What should I do?

I just implemented Game Center in an app using the new BT plugin. The new BT_quiz.m file is a bit different than before. I'll update the Game Center Tutorial when I get a chance.

Let me take a look at what I did to get it working and I'll post back a solution.

Cheers to that. :-) Thank you

@MGoBlue, you had the opportunity to take a look? Cheers.

Just added Game Center to my latest app with no issues. Great tutorial by the way JC Evans

What tutorial did you use? Thanks

@MadRod - I just looked through the quiz I'm working on, and it looks like everything from the tutorial is in the same place in my new file. The only thing that's confusing (and I'll change it) is on page 9 of the tutorial. It should probably say "Just above the following code section: //show quiz reward screen -(void)showQuizRewardScreen{" Then: Delete the section between //show scoreboard and //show quiz reward screen etc. I'll have to double check, but the code should be working.

Thanks guys. But I still can't find this (page 10 of the tutorial) "//scoreboard button shows if we have it on and if a scoreboard URL is provided" on my BT_screen_quiz.m file. Do you have it in your file? I'm using the new Interactive from BT. I think there is a different quiz plugin out there. Thanks

Ok. Yes, that's a bit different. In the "-(void)quizEnded{" saction, put this: //Submit Score Button [finishedButtons addObject:NSLocalizedString(@"quizSubmitScore", @"Submit Score")]; Right above: //try again button... [finishedButtons addObject:NSLocalizedString(@"quizTryAgain", @"Try Again")];

Madrod How you getting on? Still need help?

Madrod Here is the link if you are still struggling to find it http://www.buzztouch.com/resources/Achievement_Tutorial.pdf Good luck

I havent had the time to try it. Will let you know. Thank you

Hey, I tried the tutorial, I was able to follow all steps with no problem, but when I run the app, nothing happens regarding the Game Center. And I do have an alert in BT_screen_quiz.m @imprementation BT_screen_quiz - incomplete implementation. being struggling with this for a while. In need of help. Cheers.

And noticed that the app freezes from time to time.

Got it working. Thanks
