Skateboarder with AdMob and Leaderboard

Introduction

Welcome to this comprehensive tutorial on how to integrate AdMob and a leaderboard into your Skateboarder game using Unity. In this tutorial, we will guide you through the process of setting up AdMob, implementing interstitial ads, and creating a leaderboard using Google Play Games Services.

Prerequisites

Before we begin, make sure you have the following:

• Unity version 2019.3 or later
• AdMob account and a Unity plugin
• Google Play Games Services account and a Unity plugin
• Skateboarder game project set up in Unity

Step 1: Setting up AdMob

To set up AdMob, follow these steps:

1. Create an AdMob account if you haven't already. Go to the AdMob website and sign up for an account.
2. Create a new ad unit for your Skateboarder game. You can do this by going to the AdMob dashboard, clicking on "Create an ad unit", and selecting "Interstitial" as the ad format.
3. In your Unity project, go to the "Assets" folder and create a new folder called "AdMob".
4. Inside the "AdMob" folder, create a new file called "AdMobManager.cs". This file will contain the code for managing AdMob ads.
5. Open the "AdMobManager.cs" file and add the following code:

   
   using UnityEngine;
   using GoogleMobileAds;

public class AdMobManager : MonoBehaviour { private InterstitialAd interstitial;

void Start()
{
    // Initialize AdMob
    MobileAds.Initialize(initStatus => {
        // Create an interstitial ad
        interstitial = new InterstitialAd(this.gameObject);
        interstitial.adUnitId = "YOUR_AD_UNIT_ID";
        interstitial.LoadAd(new AdRequest.Builder().Build());
    });
}

public void ShowInterstitial()
{
    // Show the interstitial ad
    if (interstitial.IsLoaded())
    {
        interstitial.Show();
    }
}

}

Replace "YOUR_AD_UNIT_ID" with the actual ad unit ID you created in AdMob.

**Step 2: Implementing Interstitial Ads**

To implement interstitial ads, follow these steps:

1. In your Unity project, go to the "Scene" tab and select the scene where you want to display the interstitial ad.
2. Drag and drop the "AdMobManager" script onto the scene.
3. In the "AdMobManager" script, add the following code to the "Start" method:
```csharp
void Start()
{
    // Initialize AdMob
    MobileAds.Initialize(initStatus => {
        // Create an interstitial ad
        interstitial = new InterstitialAd(this.gameObject);
        interstitial.adUnitId = "YOUR_AD_UNIT_ID";
        interstitial.LoadAd(new AdRequest.Builder().Build());
    });
}

This code initializes AdMob and loads an interstitial ad.

1. To show the interstitial ad, add the following code to the "ShowInterstitial" method:

   public void ShowInterstitial()
   {
   // Show the interstitial ad
   if (interstitial.IsLoaded())
   {
       interstitial.Show();
   }
   }

   You can call the "ShowInterstitial" method from any part of your game.

Step 3: Setting up Leaderboard

To set up a leaderboard, follow these steps:

1. Create a new Google Play Games Services account if you haven't already. Go to the Google Play Games Services website and sign up for an account.
2. Create a new leaderboard for your Skateboarder game. You can do this by going to the Google Play Games Services dashboard, clicking on "Create a leaderboard", and selecting "Score" as the leaderboard type.
3. In your Unity project, go to the "Assets" folder and create a new folder called "GooglePlayGames".
4. Inside the "GooglePlayGames" folder, create a new file called "GooglePlayGamesManager.cs". This file will contain the code for managing Google Play Games Services.
5. Open the "GooglePlayGamesManager.cs" file and add the following code:

   
   using UnityEngine;
   using GooglePlayGames;

public class GooglePlayGamesManager : MonoBehaviour { private Leaderboard leaderboard;

void Start()
{
    // Initialize Google Play Games Services
    PlayGamesPlatform.InitializeInstance();
    PlayGamesPlatform.DebugLogEnabled = true;
    PlayGamesPlatform.Activate();

    // Create a leaderboard
    leaderboard = Leaderboard.CreateLeaderboard();
    leaderboard.LeaderboardID = "YOUR_LEADERBOARD_ID";
}

public void SubmitScore(int score)
{
    // Submit the score to the leaderboard
    leaderboard.SubmitScore(score, "YOUR_LEADERBOARD_ID");
}

}

Replace "YOUR_LEADERBOARD_ID" with the actual leaderboard ID you created in Google Play Games Services.

**Step 4: Implementing Leaderboard**

To implement the leaderboard, follow these steps:

1. In your Unity project, go to the "Scene" tab and select the scene where you want to display the leaderboard.
2. Drag and drop the "GooglePlayGamesManager" script onto the scene.
3. In the "GooglePlayGamesManager" script, add the following code to the "Start" method:
```csharp
void Start()
{
    // Initialize Google Play Games Services
    PlayGamesPlatform.InitializeInstance();
    PlayGamesPlatform.DebugLogEnabled = true;
    PlayGamesPlatform.Activate();

    // Create a leaderboard
    leaderboard = Leaderboard.CreateLeaderboard();
    leaderboard.LeaderboardID = "YOUR_LEADERBOARD_ID";
}

This code initializes Google Play Games Services and creates a leaderboard.

1. To submit a score to the leaderboard, add the following code to the "SubmitScore" method:

   public void SubmitScore(int score)
   {
   // Submit the score to the leaderboard
   leaderboard.SubmitScore(score, "YOUR_LEADERBOARD_ID");
   }

   You can call the "SubmitScore" method from any part of your game.

Conclusion

That's it! You have now successfully integrated AdMob and a leaderboard into your Skateboarder game using Unity. Remember to replace the placeholder IDs with your actual AdMob ad unit ID and Google Play Games Services leaderboard ID.
