Drop Ball – A Hypercasual Game with Admob Ads

Introduction

In this tutorial, we will be creating a hypercasual game called "Drop Ball" using Unity and integrating AdMob ads to monetize our game. Hypercasual games are simple, easy to play, and addictive, making them popular among mobile gamers. In this tutorial, we will cover the basics of creating a hypercasual game and integrating AdMob ads to display interstitial ads and rewarded videos.

What is Drop Ball?

Drop Ball is a simple game where the player has to drop a ball from a certain height and try to break as many blocks as possible before the ball hits the ground. The game is easy to learn, but challenging to master, making it perfect for a hypercasual game.

Prerequisites

Before we start, make sure you have the following:

• Unity 2019.4 or later
• AdMob account
• Android or iOS device for testing
• Basic knowledge of Unity and C#

Step 1: Setting up the Game

Create a new Unity project and set up the game as follows:

• Create a new 2D game
• Set the game resolution to 1080x1920
• Set the game orientation to Landscape
• Create a new scene and name it "GameScene"
• Create a new UI canvas and name it "Canvas"
• Create a new UI image and name it "Background"
• Set the background image to a simple gradient or a colorful image
• Create a new UI image and name it "Ball"
• Set the ball image to a simple circle or a ball-shaped image
• Create a new UI text and name it "ScoreText"
• Set the score text to display the player's score

Step 2: Creating the Gameplay

Create the gameplay as follows:

• Create a new C# script and name it "GameController"
• Attach the script to the Canvas
• In the script, create a public variable for the ball's initial velocity
• Create a public variable for the ball's gravity
• Create a public variable for the score
• In the Update() method, update the ball's position based on its velocity and gravity
• Check if the ball hits the ground and reset the ball's position and velocity if it does
• Check if the ball hits a block and increment the score if it does
• Update the score text to display the player's score

Step 3: Adding AdMob Ads

Add AdMob ads to the game as follows:

• Create a new AdMob account and set up a new ad unit
• Create a new C# script and name it "AdController"
• Attach the script to the Canvas
• In the script, create a public variable for the ad unit ID
• Create a public variable for the ad format (interstitial or rewarded video)
• In the Start() method, load the ad using the AdMob SDK
• In the Update() method, check if the ad is loaded and display it if it is
• Check if the ad is clicked and reward the player with coins or points if it is

Step 4: Testing the Game

Test the game on an Android or iOS device to ensure that it works as expected. Make sure to test the ad display and reward system to ensure that they work correctly.

Step 5: Publishing the Game

Publish the game on the App Store or Google Play Store to make it available to the public. Make sure to follow the guidelines and requirements for publishing a game on each platform.

Conclusion

In this tutorial, we have created a hypercasual game called "Drop Ball" using Unity and integrated AdMob ads to monetize our game. We have covered the basics of creating a hypercasual game and integrating AdMob ads to display interstitial ads and rewarded videos. With this tutorial, you should be able to create your own hypercasual game and monetize it using AdMob ads.

Code

Here is the code for the game:

using UnityEngine;
using UnityEngine.UI;
using GoogleMobileAds;

public class GameController : MonoBehaviour
{
    public float ballInitialVelocity = 10f;
    public float ballGravity = 9.8f;
    public int score = 0;

    private Rigidbody2D ballRigidbody;
    private Text scoreText;

    void Start()
    {
        ballRigidbody = GetComponent<Rigidbody2D>();
        scoreText = GetComponent<Text>();
    }

    void Update()
    {
        ballRigidbody.velocity = new Vector2(ballInitialVelocity, ballRigidbody.velocity.y);
        ballRigidbody.AddForce(Vector2.down * ballGravity, ForceMode2D.Impulse);

        if (ballRigidbody.position.y < 0)
        {
            ballRigidbody.position = new Vector2(ballRigidbody.position.x, 0);
            ballRigidbody.velocity = new Vector2(ballInitialVelocity, 0);
        }

        if (ballRigidbody.IsTouching())
        {
            score++;
            scoreText.text = "Score: " + score;
        }
    }
}

public class AdController : MonoBehaviour
{
    public string adUnitID = "YOUR_AD_UNIT_ID";
    public AdFormat adFormat = AdFormat.Interstitial;

    private AdRequest adRequest;
    private AdView adView;

    void Start()
    {
        adRequest = new AdRequest.Builder().Build();
        adView = GetComponent<AdView>();

        if (adFormat == AdFormat.Interstitial)
        {
            adView.LoadAd(adRequest);
        }
        else if (adFormat == AdFormat.RewardedVideo)
        {
            RewardedVideoAd.Load(adRequest, adUnitID, this);
        }
    }

    void OnAdLoaded()
    {
        if (adFormat == AdFormat.Interstitial)
        {
            adView.Show();
        }
        else if (adFormat == AdFormat.RewardedVideo)
        {
            RewardedVideoAd.Show(adUnitID, this);
        }
    }

    void OnAdFailedToLoad()
    {
        Debug.LogError("Ad failed to load");
    }

    void OnAdOpened()
    {
        Debug.Log("Ad opened");
    }

    void OnAdClosed()
    {
        Debug.Log("Ad closed");
    }

    void OnAdRewarded()
    {
        Debug.Log("Ad rewarded");
    }
}

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