PlayFab Integration: Virtual Currency

Virtual Currency (VC) is one of the core systems used in VR fangames.
It allows your game to reward players, sell cosmetics, track earnings, and manage in‑game economies safely through PlayFab.

This page explains how Virtual Currency works, how to set it up, and how it fits into your game’s backend.

1. What Virtual Currency Is Used For

Virtual Currency is commonly used for:

• Buying cosmetics

• Unlocking badges

• Purchasing items in the shop

• Rewarding players for gameplay

• Event rewards

• Daily login bonuses

• Leveling systems

In Gorilla Killers, our currency code is KC (Killer Coins).

2. How Virtual Currency Works in PlayFab

PlayFab handles all currency operations server‑side:

• Adding currency

• Subtracting currency

• Checking balances

• Using currency in stores

• Granting currency through CloudScript

This keeps your economy secure and prevents cheating.

3. Currency Codes

Every currency has a 2‑letter code, such as:

• KC – Kill Coins

• GC – Gold Coins

• CR – Credits

• BA – Bananas (example)

You define these in the PlayFab Economy settings

4. Setting Up Virtual Currency

Inside your PlayFab dashboard:

1. Go to Economy

2. Open Currencies

3. Add a new currency

4. Set the code (example: KC)

5. Add a display name

6. Save

Your game can now use this currency.

5. Common Currency Operations

These are the most used operations in VR fangames:

Add Currency

Used for rewards, events, or daily bonuses.

Subtract Currency

Used when buying cosmetics or items.

Get Currency Balance

Used when loading the player’s shop UI.

Grant Currency (Admin)

Used for staff tools or compensation

6. How Currency Fits Into Your Game Flow

Typical VR fangame currency flow:

1. Player logs in

2. Game loads their currency balance

3. Player earns currency by playing

4. Player spends currency in the shop

5. Game updates their balance

6. PlayFab saves the new amount

This keeps the economy consistent across sessions.

7. Best Practices

• Never modify currency directly on the client

• Use CloudScript for secure operations

• Keep currency values small and readable

• Avoid giving too much currency too fast

• Log currency changes for debugging

• Use Title Data for shop prices

8. Common Uses in Gtag‑Style Games

• Buying cosmetics

• Unlocking badges

• Event rewards

• Daily login bonuses

• Level progression

• Seasonal shops

• Limited‑time items

Virtual Currency is the backbone of most cosmetic systems.
