Helix Jump 3D (Unity Project+Android+iOS+Admob)

Introduction to Helix Jump 3D Tutorial

Welcome to the Helix Jump 3D tutorial! Helix Jump 3D is a popular mobile game where players control a blue ball that jumps and rolls down a spiral helix, collecting coins and gems while avoiding obstacles. The game is built using Unity, a popular game development engine, and is published on both Android and iOS platforms. In this tutorial, we will guide you through the process of building and publishing Helix Jump 3D using Unity, and integrating Admob for monetization.

Prerequisites

Before you start this tutorial, you should have the following:

• Unity Hub installed on your computer (free to download)
• Basic understanding of Unity and C#
• A computer with sufficient resources to run Unity (Intel Core i5 or higher, 8GB RAM or more)
• Android Studio or Xcode installed on your computer (for building and testing on Android and iOS respectively)

Step 1: Setting up the Project in Unity

1. Download and install Unity Hub from the official Unity website.
2. Launch Unity Hub and select the "Download" button next to Unity.
3. Choose the version of Unity you want to use (for this tutorial, we will use Unity 2020.3.13f1).
4. Create a new project by clicking on "New" and selecting "3D" as the project type.
5. Name your project "HelixJump3D" and set the project location.
6. Choose the " Blank" template and click on "Create".

Step 2: Creating the Game Assets

1. Create a new folder named "Assets" inside your project folder.
2. Create a new folder named "Sprites" inside "Assets".
3. Add the following sprites to "Sprites":
   • a blue ball (blueball.png)
   • a coin (coin.png)
   • a gem (gem.png)
   • a helix (helix.png)
4. Create a new folder named "Models" inside "Assets".
5. Create a new 3D model for the helix using a 3D modeling software (e.g. Blender) and add it to "Models" as "helix3d.obj".

Step 3: Setting up the Game Scene

1. Create a new scene by clicking on "GameObject" > "3D Object" > "Scene".
2. Name your scene "HelixScene".
3. Create a new empty game object named "Helix" by clicking on "GameObject" > "3D Object" > "Empty".
4. Add the "helix3d" model to "Helix" by dragging and dropping it into the Hierarchy panel.
5. Position the helix at (0, 0, 0) in the world space.
6. Create a new empty game object named "Ball" by clicking on "GameObject" > "3D Object" > "Empty".
7. Add a "Sphere" component to "Ball" by right-clicking on "Ball" and selecting "3D Object" > "Sphere".
8. Name the sphere "blueball".
9. Position the ball at (0, 0, 10) in the world space.

Step 4: Adding the Player Control

1. Create a new script by clicking on "Assets" > "Create" > "C# Script".
2. Name the script "PlayerController".
3. Attach the script to the "Ball" game object.
4. Open the script in Visual Studio Code (or your preferred code editor) and add the following code:

   
   using UnityEngine;

public class PlayerController : MonoBehaviour { public float jumpForce = 10.0f; private Rigidbody rb;

void Start()
{
    rb = GetComponent<Rigidbody>();
}

void Update()
{
    if (Input.GetButtonDown("Jump"))
    {
        rb.AddForce(Vector3.up * jumpForce, ForceMode.Impulse);
    }
}

}

5. Save the script and close Visual Studio Code.

**Step 5: Adding the Coin and Gem Collision**

1. Create a new script by clicking on "Assets" > "Create" > "C# Script".
2. Name the script "CoinGemController".
3. Attach the script to a new empty game object (e.g. "CoinGem").
4. Open the script in Visual Studio Code and add the following code:
```csharp
using UnityEngine;

public class CoinGemController : MonoBehaviour
{
    public enum Type { Coin, Gem }
    public Type type;

    void OnTriggerEnter(Collider other)
    {
        if (other.gameObject.tag == "Player")
        {
            // Collect coin/gem
            // todo: implement coin/gem collection logic
        }
    }
}

1. Add a "SphereCollider" component to the "CoinGem" game object by right-clicking on it and selecting "Physics" > "Sphere Collider".
2. Set the sphere collider's radius to 0.5f and its center to (0, 0, 0).
3. Duplicate the "CoinGem" game object and rename it to "CoinGem1".
4. Set the "CoinGem1" game object's position to (0, 1, 0).

Step 6: Setting up the Admob Plugin

1. Download and install the Admob Unity Plugin from the official Admob website.
2. Import the plugin into your Unity project by dragging and dropping the downloaded file into the "Assets" folder.
3. Create a new Admob banner by clicking on "Assets" > "Create" > "Admob Banner".
4. Configure the banner by selecting the ad unit ID, ad format, and targeting options.
5. Place the banner at the top of the screen by positioning it at (0, 100, 0) in the world space.

Step 7: Building and Publishing the Game

1. Create a new build configuration for Android by clicking on "File" > "Build Settings" > "New".
2. Select the "Android" platform and set the build settings accordingly.
3. Create a new build configuration for iOS by clicking on "File" > "Build Settings" > "New".
4. Select the "iOS" platform and set the build settings accordingly.
5. Build and publish the game on both platforms using the respective build settings.

That's it! You have now completed the Helix Jump 3D tutorial. The game should be functional and ready to be published on both Android and iOS platforms. Don't forget to add additional features and polish to the game to make it stand out from the competition.

Additional Tips and Recommendations

• Use Unity's built-in physics engine to simulate the ball's motion and collision with the helix.
• Implement coin and gem collection logic using the "CoinGemController" script.
• Use Admob's interstitial ads to monetize the game.
• Consider implementing leaderboards and achievements using Unity's built-in leaderboard and achievement systems.
• Polish the game's graphics and sound effects to make it more visually appealing and engaging.
