Bouncy Cube (Admob + GDPR + Unity)

Introduction

In this tutorial, we will be creating a simple game using Unity, AdMob, and GDPR compliance. The game will be a Bouncy Cube, where the player has to navigate a cube through a 3D environment, avoiding obstacles and collecting points. We will be using AdMob to display ads in the game, and implementing GDPR compliance to ensure that our game is compliant with the General Data Protection Regulation (GDPR).

Step 1: Setting up the Project

To start, create a new Unity project. Choose a name for your project, and select the "3D" template. Make sure to select the "Empty" project template, as we will be creating our own game assets.

Step 2: Creating the Game Assets

Create a new folder in your project called "Assets". Inside the "Assets" folder, create a new folder called "Prefabs". Inside the "Prefabs" folder, create a new prefab called "BouncyCube". This will be the main game object that we will be working with.

Create a new 3D object in the scene by going to "GameObject" > "3D Object" > "Cube". Name this object "BouncyCube". This will be the main game object that we will be working with.

Step 3: Adding the AdMob Plugin

To add the AdMob plugin to our project, we need to download the AdMob Unity plugin from the Google Developers website. Once downloaded, extract the plugin to a folder on your computer.

In the Unity editor, go to "Window" > "Package Manager". Click on the "+" button at the top right corner of the window, and select "Add package from disk". Select the AdMob plugin folder that you extracted earlier.

Once the plugin is installed, we need to set up the AdMob plugin in our project. Go to "Edit" > "Project Settings" > "Player". In the "Other Settings" section, scroll down to the "AdMob" section and fill in the required information, such as your AdMob app ID and ad unit ID.

Step 4: Implementing AdMob

To implement AdMob in our game, we need to create a new script that will handle the ad display. Create a new script by going to "Assets" > "Create" > "C# Script". Name this script "AdManager".

Open the "AdManager" script and add the following code:

using UnityEngine;
using GoogleMobileAds;

public class AdManager : MonoBehaviour
{
    private InterstitialAd interstitial;

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

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

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

Step 5: Implementing GDPR Compliance

To implement GDPR compliance in our game, we need to add a new script that will handle the user's consent. Create a new script by going to "Assets" > "Create" > "C# Script". Name this script "GDPRManager".

Open the "GDPRManager" script and add the following code:

using UnityEngine;
using GoogleMobileAds;

public class GDPRManager : MonoBehaviour
{
    private bool userHasConsented = false;

    void Start()
    {
        // Check if the user has consented to data collection
        if (PlayerPrefs.GetInt("GDPR_CONSENT", 0) == 1)
        {
            userHasConsented = true;
        }
    }

    void ShowConsentDialog()
    {
        // Show a consent dialog to the user
        Debug.Log("Show consent dialog");
    }

    void HandleConsent(bool consentGiven)
    {
        // Handle the user's consent
        if (consentGiven)
        {
            userHasConsented = true;
            PlayerPrefs.SetInt("GDPR_CONSENT", 1);
        }
        else
        {
            userHasConsented = false;
            PlayerPrefs.SetInt("GDPR_CONSENT", 0);
        }
    }
}

This script will check if the user has consented to data collection, and will show a consent dialog to the user if they have not consented.

Step 6: Integrating the AdMob and GDPR Scripts

To integrate the AdMob and GDPR scripts, we need to add the scripts to our game objects. Select the "BouncyCube" prefab and add the "AdManager" script to it. Also, add the "GDPRManager" script to the "BouncyCube" prefab.

Step 7: Testing the Game

To test the game, we need to run the game in the Unity editor. Select the "BouncyCube" prefab and click on the "Play" button in the Unity editor. The game will start, and you should see the ad displayed at the start of the game. If you click on the ad, it will open the AdMob app.

If you want to test the GDPR compliance, you can simulate the user's consent by modifying the "GDPR_CONSENT" preference in the PlayerPrefs. For example, you can set the preference to 1 to simulate the user's consent.

Conclusion

In this tutorial, we have created a simple game using Unity, AdMob, and GDPR compliance. We have implemented AdMob to display ads in the game, and implemented GDPR compliance to ensure that our game is compliant with the General Data Protection Regulation (GDPR). We have also tested the game to ensure that it works as expected.

I hope this tutorial has been helpful in creating a simple game using Unity, AdMob, and GDPR compliance. If you have any questions or need further assistance, please don't hesitate to ask.
