Zamba : (Android Studio+Admob+Reward Video ads+Inapp purchase+Leaderboards)

Introduction

Welcome to this comprehensive tutorial on how to use the Zamba game engine to create a mobile game with Android Studio, AdMob, Reward Video ads, In-app purchases, and Leaderboards. Zamba is a popular game engine that allows developers to create 2D games for Android and iOS devices. In this tutorial, we will guide you through the process of setting up a new project in Android Studio, integrating AdMob for monetization, adding Reward Video ads, implementing In-app purchases, and creating Leaderboards.

Prerequisites

Before starting this tutorial, make sure you have the following:

• Android Studio installed on your computer
• A basic understanding of Java or Kotlin programming language
• A Google Play Console account for AdMob and Google Play Store
• A Zamba game engine account for creating and publishing your game

Step 1: Setting up a new project in Android Studio

1. Open Android Studio and click on "Start a new Android Studio project" button.
2. Choose "Empty Activity" as the project template and click "Next".
3. Fill in the project details, such as project name, package name, and location.
4. Click "Finish" to create the project.

Step 2: Integrating AdMob

1. Open the project structure in Android Studio and navigate to the "app" folder.
2. Create a new folder called "admob" and add the AdMob SDK to it.
3. Add the following dependencies to the "build.gradle" file:

   dependencies {
   implementation 'com.google.android.gms:play-services-ads:20.6.0'
   }

4. Create a new Java class called "AdMobManager" and add the following code:

   
   import com.google.android.gms.ads.AdRequest;
   import com.google.android.gms.ads.AdView;
   import com.google.android.gms.ads.MobileAds;

public class AdMobManager { private AdView adView;

public AdMobManager(Context context) {
    MobileAds.initialize(context);
    adView = new AdView(context);
    adView.setAdSize(AdSize.BANNER);
    adView.setAdUnitId("YOUR_AD_UNIT_ID");
}

public void loadAd() {
    AdRequest adRequest = new AdRequest.Builder().build();
    adView.loadAd(adRequest);
}

public void showAd() {
    adView.setVisibility(View.VISIBLE);
}

public void hideAd() {
    adView.setVisibility(View.GONE);
}

}

5. Replace "YOUR_AD_UNIT_ID" with your actual AdMob ad unit ID.

**Step 3: Adding Reward Video ads**

1. Create a new Java class called "RewardVideoManager" and add the following code:
```java
import com.google.android.gms.ads.reward.RewardItem;
import com.google.android.gms.ads.reward.RewardVideoAd;

public class RewardVideoManager {
    private RewardVideoAd rewardVideoAd;

    public RewardVideoManager(Context context) {
        rewardVideoAd = new RewardVideoAd(context, "YOUR_REWARD_VIDEO_AD_UNIT_ID");
    }

    public void loadAd() {
        rewardVideoAd.loadAd(new AdRequest.Builder().build());
    }

    public void showAd() {
        rewardVideoAd.show();
    }

    public void onReward(RewardItem rewardItem) {
        // Handle reward
    }
}

1. Replace "YOUR_REWARD_VIDEO_AD_UNIT_ID" with your actual AdMob reward video ad unit ID.

Step 4: Implementing In-app purchases

1. Create a new Java class called "InAppPurchaseManager" and add the following code:

   
   import com.android.billingclient.api.BillingClient;
   import com.android.billingclient.api.BillingClientState;
   import com.android.billingclient.api.BillingFlowParams;
   import com.android.billingclient.api.Purchase;

public class InAppPurchaseManager { private BillingClient billingClient;

public InAppPurchaseManager(Context context) {
    billingClient = BillingClient.newBuilder(context).setListener(new BillingClientStateListener() {
        @Override
        public void onBillingSetupFinished(int responseCode) {
            // Handle billing setup
        }

        @Override
        public void onBillingServiceDisconnected() {
            // Handle billing service disconnection
        }
    }).build();
}

public void initiatePurchase(String sku) {
    BillingFlowParams flowParams = BillingFlowParams.newBuilder()
           .setSku(sku)
           .setType(BillingClient.SkuType.INAPP)
           .build();
    billingClient.launchBillingFlow(flowParams);
}

public void onPurchase(Purchase purchase) {
    // Handle purchase
}

}

**Step 5: Creating Leaderboards**

1. Create a new Java class called "LeaderboardManager" and add the following code:
```java
import com.google.android.gms.games.Leaderboards;
import com.google.android.gms.games.Leaderboards.LeaderboardScore;

public class LeaderboardManager {
    private Leaderboards leaderboards;

    public LeaderboardManager(Context context) {
        leaderboards = new Leaderboards(context);
    }

    public void submitScore(String leaderboardId, int score) {
        leaderboards.submitScore(leaderboardId, score);
    }

    public void getLeaderboardScore(String leaderboardId, int score) {
        leaderboards.getLeaderboardScore(leaderboardId, score);
    }
}

Step 6: Integrating Zamba game engine

1. Download and install the Zamba game engine on your computer.
2. Create a new Zamba project and add the following code to the "main.lua" file:

   
   local game = require("game")

local function onGameStart() -- Initialize AdMob and Reward Video ads local admobManager = AdMobManager.new() admobManager.loadAd()

-- Initialize In-app purchases
local inAppPurchaseManager = InAppPurchaseManager.new()
inAppPurchaseManager.initiatePurchase("YOUR_SKU")

-- Initialize Leaderboards
local leaderboardManager = LeaderboardManager.new()
leaderboardManager.submitScore("YOUR_LEADERBOARD_ID", 0)

end

game.onGameStart = onGameStart

3. Replace "YOUR_SKU" with your actual In-app purchase SKU and "YOUR_LEADERBOARD_ID" with your actual Leaderboard ID.

**Conclusion**

In this tutorial, we have covered the basics of using the Zamba game engine to create a mobile game with Android Studio, AdMob, Reward Video ads, In-app purchases, and Leaderboards. By following these steps, you should be able to create a fully functional game that can be published on the Google Play Store. Remember to replace the placeholder values with your actual AdMob ad unit ID, reward video ad unit ID, In-app purchase SKU, and Leaderboard ID.
