I have spent countless days trying to learn how to implement these features into my game. Unfortunately, i have absolutely no java scripting skills which makes this task evidently more difficult for me. Can anyone be so kind and show me how to add these features with CocoonJS? I have a premium account with them already and can use the extensions.
Thank you very much for reading this and taking the time to help.
EDIT: I only need to use the game center extension for the leader boards option (grab/send a score to/from friends list). I do not need multiplayer gaming.
