Cute Animal Puzzle Kids : Unity3D + Admob Ads + Easy Reskin

Introduction

Welcome to this comprehensive tutorial on creating a cute animal puzzle game for kids using Unity3D, AdMob ads, and easy reskinning. In this tutorial, we will guide you through the process of creating a engaging and fun puzzle game that is suitable for kids, while also incorporating AdMob ads to monetize your game. Additionally, we will show you how to easily reskin the game to create different versions with different animal characters.

Prerequisites

Before starting this tutorial, you should have the following:

• Unity3D installed on your computer
• Basic knowledge of Unity3D and C# programming
• A computer with a stable internet connection

Step 1: Setting up the Project

1. Open Unity3D and create a new project by selecting "3D" or "2D" game under the "New" menu.
2. Name your project and select a location to save it.
3. Create a new scene by selecting "File" > "New Scene" or by using the shortcut "Ctrl + N" (Windows) or "Command + N" (Mac).
4. Set the scene's resolution to 1080p (1920x1080) and the aspect ratio to 16:9.

Step 2: Creating the Puzzle Game

1. Create a new 3D object by selecting "GameObject" > "3D Object" > "Cube" or by using the shortcut "Ctrl + Shift + C" (Windows) or "Command + Shift + C" (Mac).
2. Name the cube "PuzzlePiece" and set its position to (0, 0, 0).
3. Create a new script by selecting "Assets" > "Create" > "C# Script" and name it "PuzzlePieceScript".
4. Attach the script to the PuzzlePiece object by selecting the object and then clicking on the "Add Component" button and selecting the script.
5. In the PuzzlePieceScript, add the following code:

   
   using UnityEngine;

public class PuzzlePieceScript : MonoBehaviour { public int pieceId; public Sprite[] pieceSprites;

private void Start()
{
    GetComponent<SpriteRenderer>().sprite = pieceSprites[pieceId];
}

}

This script will set the sprite of the puzzle piece based on its pieceId.

**Step 3: Creating the Puzzle Grid**

1. Create a new 2D object by selecting "GameObject" > "2D Object" > "Sprite" or by using the shortcut "Ctrl + Shift + S" (Windows) or "Command + Shift + S" (Mac).
2. Name the sprite "PuzzleGrid" and set its position to (0, 0).
3. Create a new script by selecting "Assets" > "Create" > "C# Script" and name it "PuzzleGridScript".
4. Attach the script to the PuzzleGrid object by selecting the object and then clicking on the "Add Component" button and selecting the script.
5. In the PuzzleGridScript, add the following code:
```csharp
using UnityEngine;

public class PuzzleGridScript : MonoBehaviour
{
    public int gridSizeX;
    public int gridSizeY;
    public PuzzlePieceScript[] puzzlePieces;

    private void Start()
    {
        for (int i = 0; i < gridSizeX; i++)
        {
            for (int j = 0; j < gridSizeY; j++)
            {
                int pieceId = i + j * gridSizeX;
                PuzzlePieceScript piece = puzzlePieces[pieceId];
                piece.transform.position = new Vector3(i * 100, j * 100, 0);
            }
        }
    }
}

This script will create a grid of puzzle pieces and set their positions based on their pieceId.

Step 4: Adding AdMob Ads

1. Create a new AdMob ad unit by going to the AdMob website and following the instructions.
2. Download the AdMob SDK for Unity and import it into your project by selecting "Assets" > "Import Package" > "Custom Package" and selecting the SDK.
3. Create a new script by selecting "Assets" > "Create" > "C# Script" and name it "AdMobScript".
4. Attach the script to a new GameObject by selecting the object and then clicking on the "Add Component" button and selecting the script.
5. In the AdMobScript, add the following code:

   
   using UnityEngine;
   using Google.MobileAds;

public class AdMobScript : MonoBehaviour { private MobileAd _ad;

private void Start()
{
    _ad = new MobileAd(this);
    _ad.LoadAd();
}

private void OnAdLoaded()
{
    _ad.Show();
}

}

This script will load and display an AdMob ad.

**Step 5: Reskinning the Game**

1. Create a new folder in your project's Assets folder and name it "Animals".
2. Create a new sprite by selecting "Assets" > "Create" > "Sprite" and name it "Dog.png".
3. Add the sprite to the Animals folder.
4. In the PuzzlePieceScript, add the following code:
```csharp
using UnityEngine;

public class PuzzlePieceScript : MonoBehaviour
{
    public int pieceId;
    public Sprite[] pieceSprites;

    private void Start()
    {
        GetComponent<SpriteRenderer>().sprite = pieceSprites[pieceId];
    }
}

This script will set the sprite of the puzzle piece based on its pieceId.

1. Create a new script by selecting "Assets" > "Create" > "C# Script" and name it "AnimalScript".
2. Attach the script to a new GameObject by selecting the object and then clicking on the "Add Component" button and selecting the script.
3. In the AnimalScript, add the following code:

   
   using UnityEngine;

public class AnimalScript : MonoBehaviour { public Sprite animalSprite;

private void Start()
{
    GetComponent<SpriteRenderer>().sprite = animalSprite;
}

}

This script will set the sprite of the animal based on the animalSprite variable.

8. Create a new folder in your project's Assets folder and name it "Animals".
9. Create a new sprite by selecting "Assets" > "Create" > "Sprite" and name it "Cat.png".
10. Add the sprite to the Animals folder.

**Conclusion**

In this tutorial, we have created a cute animal puzzle game for kids using Unity3D, AdMob ads, and easy reskinning. We have also shown you how to create different versions of the game with different animal characters. With this tutorial, you should be able to create your own puzzle game for kids and monetize it with AdMob ads.
