Monetize Your Game Faster: Integrating In‑App Purchase & Ad Modules into VegaDigi Game Scripts

Launching a mobile game is exciting, but without a solid monetization strategy it can remain just a hobby project. At VegaDigi, we provide ready‑to‑deploy game scripts that already include clean code, modern graphics, and flexible architecture. The missing piece for many developers is the integration of proven revenue‑generating features such as in‑app purchases (IAP), rewarded video ads, and banner ads. This guide walks you through a practical, step‑by‑step process to embed these modules into any VegaDigi game script, so you can launch a profit‑driving game in weeks rather than months.

Why Choose VegaDigi Game Scripts?

• Ready‑to‑deploy: Fully functional source code with documentation.
• Clean, modular architecture: Easy to extend with third‑party SDKs.
• Cross‑platform support: Android, iOS, and HTML5 builds.
• Affordable pricing: Reduce development cost by up to 70% compared to building from scratch.

These strengths give you a solid foundation to focus on what matters most – adding monetization and getting your game into the hands of players.

Step 1 – Choose the Right Game Script

VegaDigi offers a variety of game scripts across genres – puzzle, arcade, endless runner, and casual RPG. Select a script that matches your game idea and check the following criteria:

1. Source code access: Ensure you have the full Unity or native Android/JavaScript project.
2. Documentation quality: Look for clear setup instructions and API references.
3. Modular design: Scripts that separate UI, gameplay, and services layers make IAP/ad integration smoother.

For this tutorial we’ll use the popular “Space Runner” Unity script (available in the VegaDigi marketplace), but the same steps apply to any of our game scripts.

Step 2 – Set Up Your Development Environment

Before adding monetization, ensure your environment matches the script’s requirements:

• Unity 2021.3 LTS or later
• Android Build Support (SDK & NDK)
• iOS Build Support (Xcode 14+ for Mac users)
• Git (optional but recommended for version control)

Clone the repository, open the .unityproj file, and run the demo scene to verify that the base game works correctly.

Step 3 – Choose Your Monetization Platforms

VegaDigi scripts are platform‑agnostic, allowing you to pick the best SDKs for your target market. The most common choices are:

All three SDKs provide Unity packages, which means you can integrate them directly into the Unity project without native code changes.

Step 4 – Integrate Google Play Billing (Android IAP)

1. Install the Unity IAP package via Window → Package Manager → Unity IAP. Enable Google Play Billing in the IAP Settings.
2. Configure product IDs in the GooglePlayTuningSettings.asset. Use the IDs you created in the Google Play Console (e.g., com.vegadigi.spacerunner.coinpack1).
3. Create a PurchaseManager script (or extend the existing ShopManager.cs that comes with the script). Example snippet:

   using UnityEngine.Purchasing;
   public class PurchaseManager : IStoreListener {
       private static IStoreController controller;
       private static IExtensionProvider extensions;
       public void InitializePurchasing() {
           var builder = ConfigurationBuilder.Instance(StandardPurchasingModule.Instance());
           builder.AddProduct("coinpack1", ProductType.Consumable);
           UnityPurchasing.Initialize(this, builder);
       }
       // Implement OnInitialized, OnInitializeFailed, ProcessPurchase, OnPurchaseFailed ...
   }
   

4. Hook the manager to UI buttons (e.g., “Buy Coins” button). Call PurchaseManager.Instance.BuyProductID("coinpack1") on click.
5. Test with Google Play’s internal test track. Upload a signed APK, add tester accounts, and verify purchases in the sandbox.

Once the IAP flow works on Android, repeat the same steps for iOS using StoreKit (Unity IAP automatically switches based on the platform).

Step 5 – Add Rewarded Video Ads (AdMob)

1. Import the Google Mobile Ads Unity plugin from the official repo or via the Unity Asset Store.
2. Create an AdMob account and generate an App ID and Ad Unit IDs for rewarded video and banner ads.
3. Initialize the SDK in a startup script (e.g., AdManager.cs):

   using GoogleMobileAds.Api;
   public class AdManager : MonoBehaviour {
       private RewardedAd rewardedAd;
       void Start() {
           MobileAds.Initialize(appId);
           RequestRewardedAd();
       }
       void RequestRewardedAd() {
           rewardedAd = new RewardedAd(rewardedAdUnitId);
           rewardedAd.LoadAd(new AdRequest.Builder().Build());
       }
       public void ShowRewardedAd() {
           if (rewardedAd.IsLoaded()) rewardedAd.Show();
       }
   }
   

4. Connect the ad to gameplay rewards. In your GameManager.cs, call
