Jumper Game with AdMob and Leaderboard

Introduction

The Jumper Game is a popular open-source game that has been widely used as a template for creating 2D platformer games. In this tutorial, we will show you how to integrate AdMob and a leaderboard into the Jumper Game using Unity. AdMob is a popular mobile advertising platform that allows you to monetize your game by displaying ads to your users. A leaderboard is a feature that allows users to compete with each other by submitting their scores and ranking them against other players.

Prerequisites

Before starting this tutorial, you should have the following:

• Unity 2019.4 or later
• The Jumper Game project downloaded and imported into Unity
• A Google AdMob account
• A Google Play Games account (for leaderboard integration)

Step 1: Set up AdMob

To set up AdMob, follow these steps:

1. Go to the AdMob website and sign in with your Google account.
2. Click on the "Create an app" button and enter your app's name, package name, and other details.
3. Select the "Mobile" platform and choose the ad format you want to use (e.g. banner, interstitial, rewarded video).
4. Click on the "Create" button to create your AdMob app.
5. In the AdMob dashboard, click on the "App settings" tab and copy the AdMob app ID.

Step 2: Set up the Jumper Game

To set up the Jumper Game, follow these steps:

1. Open the Jumper Game project in Unity.
2. Create a new folder in the project hierarchy and name it "AdMob".
3. Create a new script in the AdMob folder and name it "AdMobManager".
4. In the AdMobManager script, add the following code:

   
   using UnityEngine;
   using Google.MobileAds;

public class AdMobManager : MonoBehaviour { private MobileAdView adView;

void Start()
{
    // Initialize AdMob
    MobileAds.Initialize(initStatus => {
        // Create a banner ad
        adView = new MobileAdView("YOUR_ADMOB_APP_ID", AdSize.SmartBanner);
        adView.SetPosition(AdPosition.Bottom);
        adView.SetAdListener(new AdListener());
        adView.LoadAd(new AdRequest.Builder().Build());
    });
}

void OnGUI()
{
    // Display the banner ad
    GUI.Box(new Rect(0, Screen.height - 50, Screen.width, 50), adView);
}

}

Replace "YOUR_ADMOB_APP_ID" with your actual AdMob app ID.

**Step 3: Integrate AdMob with the Jumper Game**

To integrate AdMob with the Jumper Game, follow these steps:

1. In the Jumper Game scene, add the AdMobManager script to the game object.
2. In the AdMobManager script, set the adView to the banner ad you created in Step 1.
3. In the Jumper Game scene, add a new UI element (e.g. a button) and set its position to the bottom of the screen.
4. In the AdMobManager script, set the adView to the UI element you created in Step 3.

**Step 4: Set up the Leaderboard**

To set up the leaderboard, follow these steps:

1. Go to the Google Play Games website and sign in with your Google account.
2. Click on the "Create a game" button and enter your game's name, package name, and other details.
3. Select the "Leaderboard" feature and choose the type of leaderboard you want to create (e.g. score, time).
4. Click on the "Create" button to create your leaderboard.
5. In the Google Play Games dashboard, click on the "Leaderboard" tab and copy the leaderboard ID.

**Step 5: Integrate the Leaderboard with the Jumper Game**

To integrate the leaderboard with the Jumper Game, follow these steps:

1. In the Jumper Game scene, add a new script and name it "LeaderboardManager".
2. In the LeaderboardManager script, add the following code:
```csharp
using UnityEngine;
using Google.PlayGames;

public class LeaderboardManager : MonoBehaviour
{
    private PlayGamesPlatform playGamesPlatform;

    void Start()
    {
        // Initialize Play Games
        playGamesPlatform = PlayGamesPlatform.Instance();
        playGamesPlatform.InitializeInstance();
        playGamesPlatform.SetLeaderboardListener(this);
    }

    void OnLeaderboardScoreUploaded(int score)
    {
        // Upload the score to the leaderboard
        playGamesPlatform.ShowLeaderboardUI();
    }
}

Step 6: Test the Game

To test the game, follow these steps:

1. Build and run the Jumper Game on your device or emulator.
2. Play the game and earn points by jumping and collecting coins.
3. When you earn points, the leaderboard will be updated and you will be able to view your score and rank.
4. You can also test the AdMob ads by clicking on the banner ad and viewing the ad.

That's it! You have successfully integrated AdMob and a leaderboard into the Jumper Game using Unity.
