Using Credits

Credits are a numeric attribute of each game user. It is a simple integer value. You can add them manually and they are detracted automatically upon store item purchases.

What follows is a script to demonstrate the full life cycle of credits on a signed-in user:

1. prints the credits your signed-in user has
2. prints the cost of the first store item
3. adds credits to your user

Because this operation synchronizes with the server it requires a callback. Upon success, you will see the user has now more credits when logged. At this point in time, you can run the Purchase Store Item function successfully.
