I've managed to get game services to work with someones help myself. But it's a long and arduous process with a lot of steps...
Maybe one day I'll try to gather everything I've learned and make a nice, easy to follow tutorial.
But for now just private message me with exactly what you've done so far and where you are stuck and I'll try to help and guide you through it.
Fantastic, glad its at least possible! I'm just writing a PM with all the details. Thanks!
I am also having a hard time to make Google Play Game Services and Game Center to work with native and cranberry plugins. I've tried all tutorials but things simply don't work. Any help would be appreciated!
Google play is yet to be tackled, but Game Center was from what I can remember,straight forward. The built in game center expressions work just fine on the construct side. Then just export with cordova. Wack the cordova files into the www folder then build for iOS. Obviously you'll have to install the plugin into the folder, for that just type "cordova plugin add (plugin directory)". Also, make sure you have sandbox enabled on your testing device via: settings > game center. Alternatively just try in the xcode simulator.
If you need some more info on game center, just PM me where your up to and I'll see what I can do.
Thanks for all the help!
