BYOND now allows authors to set up "credits" that can be used in-game, similar to the old BYONDimes but used for individual games. The author can create packages for this just like with subscriptions. Three new procs have been introduced to support this:

world.GetCredits(player): Get a player's credits for the hub entry.
world.PayCredits(player,credits,note): Deduct credits for this hub entry, but fail if the player doesn't have enough.
world.AddCredits(player,credits,note): Add credits to the player's account.

These procs work like the medal and score procs, in that they will contact the hub and will return null if hub contact fails. They require a hub password.
