Can't get Game Center to work

Hi you all, I have followed the tutorial that can be found @ https://coronalabs.com/blog/2012/01/17/tutorial-game-center-integration-ios/ to integrate the Game Center in my game.

The code I’m using is: 

local gameNetwork = require "gameNetwork" local loggedIntoGC = false -- called after the "init" request has completed local function initCallback( event ) if event.data then loggedIntoGC = true native.showAlert( "Success!", "User has logged into Game Center", { "OK" } ) else loggedIntoGC = false native.showAlert( "Fail", "User is not logged into Game Center", { "OK" } ) end end -- function to listen for system events local function onSystemEvent( event ) if event.type == "applicationStart" then gameNetwork.init( "gamecenter", initCallback ) return true end end Runtime:addEventListener( "system", onSystemEvent )

 and I always get “Fail, User is not logged into Game Center”.

Of course I have enabled the Game Center in iTunes Connect.

Then, I would like to show the leatherboard, that I have setted up via iTunes Connect.

According to the Corona documentation, the code I have to use is:

gameNetwork.show( "leaderboards", { leaderboard = { category = "com.appledts.EasyTapList" }, listener = onGameNetworkPopupDismissed } )

but what does “category” stand for? Is it the leatherboard ID?

Thanks.

Are you testing this on a device?

Yes, I’m testing it on the iPhone 6 Plus (iOS 8.4.1)

Hi @estiennelorenzo,

Three comments here:

  1. 99% likely reason for this issue is that on iOS 8.x, you need to enable to Game Center “sandbox” for testing. On the device, go under Settings > Game Center and look for the “Sandbox” switch (then turn it on). If that switch does NOT appear there, make sure that your device is configured as a “Developer” device within Xcode.

  2. Trying to show the “com.appledts.EasyTapList” leaderboard isn’t really applicable to your own test app. That’s a leaderboard used for testing with Apple’s “GKTapper” account. You should specify your own leaderboard category instead.

  3. I do not recommend using that ancient tutorial on Game Center. Some of it may still be valid, but a better resource is actually the documentation for the Game Center plugin:

Hi Brent, thank you, now it is working.

You were right, the sandbox switch was turned off.

Also thanks for the brand new documentation.

Just one more thing @Brent Sorrentino. Does “category” stand for “Leatherboard ID” in iTunes Connect?

Thanks.

Hi again,

Yes, “category” represents the leaderboard ID. :slight_smile:
