Coloring Book Kids Game | Unity Project With Admob for Android and iOS

Introduction

Welcome to the Coloring Book Kids Game | Unity Project With Admob tutorial! In this comprehensive guide, we will walk you through the process of creating and publishing a coloring book game for both Android and iOS devices using Unity and AdMob. The game is designed for kids and features various coloring pages, brushes, and a user-friendly interface.

By the end of this tutorial, you will have a fully functional game that you can distribute to the Google Play Store and Apple App Store. So, let's get started!

Prerequisites

Before we begin, please make sure you have:

1. Unity Hub installed on your computer (latest version)
2. Familiarity with Unity's interface and basic scripting
3. A basic understanding of AdMob and how to set up ad networks
4. A code editor or IDE of your choice
5. A graphics tablet or a mouse (for creating artwork)

Getting Started with the Project

First, download the Unity project file (ColoringBookKids.zip) from GitHub or the Unity Asset Store. Extract the zip file to a folder on your computer. This will contain the project files, scripts, and assets needed for the game.

Setting up the Project in Unity

1. Open Unity Hub and select the Unity 2020.3 (or the latest version) to open.
2. Create a new project and select the "3D" option.
3. Name your project "ColoringBookKids" and select a project location.
4. Open the extracted project files and drag the "ColoringBookKids" folder into the Unity project window.
5. Wait for Unity to load the project files and assets.

Understanding the Project Structure

The project consists of several folders and scenes:

1. Assets: Contains all the game assets, including artwork, audio files, and other resources.
2. Scenes: Contains the game scenes, including the main game scene, title screen, and options menu.
3. Scripts: Contains the game scripts, including the coloring page script, brush script, and ad script.
4. Prefabs: Contains the game prefabs, including the coloring page prefab and brush prefab.

Setting up AdMob in the Project

To integrate AdMob into the project, you need to follow these steps:

1. Create a new AdMob account or use an existing one.
2. Set up a new ad unit for each platform (Android and iOS).
3. Create a new Unity plugin for AdMob and copy the plugin files into the project's "Assets/Plugins" folder.
4. Import the AdMob plugin into Unity by clicking on "Assets" > "Import Package" > "Custom Package" and selecting the plugin files.
5. Set up the ad script by creating a new script in the "Scripts" folder and copying the AdMob script code from the plugin files.

Creating the Coloring Pages

The coloring pages are the core of the game, and they need to be created before we can implement the game logic. We will use Unity's Canvas and UI components to create the coloring pages.

1. Create a new canvas in the main game scene by clicking on "GameObject" > "UI" > "Canvas".
2. Create a new image component by clicking on the canvas and selecting "Image" from the menu.
3. Set the image component's source image to a colorable image file (e.g., PNG or JPEG).
4. Create a new UI element (e.g., rectangle or button) and use it as a brush selector.
5. Create multiple coloring pages by duplicating the canvas and image components.

Implementing Game Logic

Now that we have created the coloring pages, let's implement the game logic using C# scripts.

1. Create a new script in the "Scripts" folder and name it "ColoringPageScript".
2. Attach the script to each coloring page game object.
3. Write the code to handle user input, brush selection, and coloring page updates.

Brush Script

Create a new script in the "Scripts" folder and name it "BrushScript".

1. Attach the script to each brush game object.
2. Write the code to handle brush selection, brush size, and color changes.

Ad Script

Create a new script in the "Scripts" folder and name it "AdScript".

1. Attach the script to the main game scene.
2. Write the code to display ads at specific times or intervals.

Final Steps

Before we publish the game, let's make sure everything is working correctly:

1. Run the game in the Unity editor to test the game logic and ad integration.
2. Fix any errors or bugs that you encounter.
3. Optimize the game performance and graphics quality.
4. Prepare the game for release by setting up the build settings, icon, and splash screen.

Publishing the Game

To publish the game, follow these steps:

1. Build the game for Android and iOS using the Unity build settings.
2. Create a keystore for Android and a provisioning profile for iOS.
3. Set up the Google Play Store and Apple App Store accounts.
4. Upload the game to the respective stores and wait for approval.

That's it! With this comprehensive tutorial, you should now have a fully functional coloring book game with AdMob integration and ready to be published to the Google Play Store and Apple App Store. Happy coding!
