Faster Car Race – (Unity – Admob)

Introduction

Welcome to the Faster Car Race tutorial! In this tutorial, we will guide you through the process of creating a racing game in Unity with AdMob integration. We will cover the steps to set up the game, implement the racing mechanics, and add AdMob ads to monetize your game.

What you will learn

By the end of this tutorial, you will have a complete understanding of how to:

1. Set up a new Unity project and create a racing game scene.
2. Implement the racing mechanics, including car movement, collision detection, and scoring.
3. Add AdMob ads to your game, including banner ads and interstitial ads.
4. Test and optimize your game for performance and monetization.

Prerequisites

Before starting this tutorial, you should have:

1. Unity installed on your computer.
2. Basic knowledge of Unity and C# programming.
3. A computer with a decent graphics card and processor.

Step 1: Setting up the Unity Project

1. Open Unity and create a new 3D project.
2. Name your project "Faster Car Race" and choose a location to save it.
3. Set the project's resolution to 1080p (1920x1080) and the aspect ratio to 16:9.
4. Create a new scene by going to File > New Scene > 3D.
5. Name your scene "MainScene" and set the scene's background color to a light blue.

Step 2: Creating the Car Model

1. Create a new 3D object by going to GameObject > 3D Object > Cube.
2. Name the object "Car" and scale it to a size that fits your scene.
3. Add a Mesh Renderer component to the Car object by going to Component > Rendering > Mesh Renderer.
4. Add a Collider component to the Car object by going to Component > Physics > Box Collider.
5. Create a new material by going to Window > Materials > Standard > New Material.
6. Name the material "CarMaterial" and set its color to a bright red.

Step 3: Implementing the Racing Mechanics

1. Create a new script by going to Window > C# Scripts > New Script.
2. Name the script "CarController" and attach it to the Car object.
3. In the CarController script, add the following code:

   
   using UnityEngine;

public class CarController : MonoBehaviour { public float speed = 10.0f; public float acceleration = 5.0f; public float braking = 5.0f;

private Rigidbody rb;

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

void Update()
{
    float horizontalInput = Input.GetAxis("Horizontal");
    float verticalInput = Input.GetAxis("Vertical");

    Vector3 movement = new Vector3(horizontalInput, 0, verticalInput);

    rb.AddForce(movement * speed, ForceMode.VelocityChange);

    if (Input.GetButton("Jump"))
    {
        rb.AddForce(Vector3.up * acceleration, ForceMode.Impulse);
    }

    if (Input.GetButton("Brake"))
    {
        rb.AddForce(Vector3.down * braking, ForceMode.Impulse);
    }
}

}

4. Create a new script by going to Window > C# Scripts > New Script.
5. Name the script "Track" and attach it to a new object in the scene.
6. In the Track script, add the following code:
```csharp
using UnityEngine;

public class Track : MonoBehaviour
{
    public float trackLength = 100.0f;
    public float trackWidth = 10.0f;

    private Vector3 trackStart;
    private Vector3 trackEnd;

    void Start()
    {
        trackStart = transform.position;
        trackEnd = trackStart + new Vector3(trackLength, 0, 0);
    }

    void Update()
    {
        float distance = Vector3.Distance(transform.position, trackEnd);

        if (distance > trackLength)
        {
            transform.position = trackStart;
        }
    }
}

1. Create a new script by going to Window > C# Scripts > New Script.
2. Name the script "Score" and attach it to a new object in the scene.
3. In the Score script, add the following code:

   
   using UnityEngine;

public class Score : MonoBehaviour { public int score = 0;

void Update()
{
    score++;
}

}

**Step 4: Adding AdMob Ads**

1. Create a new AdMob account and set up a new ad unit.
2. Download the AdMob SDK for Unity and import it into your project.
3. Create a new script by going to Window > C# Scripts > New Script.
4. Name the script "AdMob" and attach it to a new object in the scene.
5. In the AdMob script, add the following code:
```csharp
using UnityEngine;
using Google.MobileAds;

public class AdMob : MonoBehaviour
{
    private MobileAdView bannerAd;
    private InterstitialAd interstitialAd;

    void Start()
    {
        // Initialize the AdMob SDK
        MobileAds.Initialize(this.Init);

        // Create a banner ad
        bannerAd = new MobileAdView();
        bannerAd.AdUnitId = "YOUR_BANNER_AD_UNIT_ID";
        bannerAd.Position = AdPosition.Bottom;
        bannerAd.Size = AdSize.SmartBanner;
        bannerAd.LoadAd();

        // Create an interstitial ad
        interstitialAd = new InterstitialAd();
        interstitialAd.AdUnitId = "YOUR_INTERSTITIAL_AD_UNIT_ID";
        interstitialAd.LoadAd();
    }

    void Update()
    {
        // Show the banner ad
        bannerAd.Show();

        // Show the interstitial ad
        if (Input.GetButtonDown("ShowAd"))
        {
            interstitialAd.Show();
        }
    }
}

1. Replace "YOUR_BANNER_AD_UNIT_ID" and "YOUR_INTERSTITIAL_AD_UNIT_ID" with your actual AdMob ad unit IDs.

Step 5: Testing and Optimizing the Game

1. Test your game by running it in the Unity editor or building it for a mobile device.
2. Optimize your game for performance and monetization by adjusting the ad frequency, ad placement, and ad size.
3. Analyze your game's performance using Unity's built-in analytics tools or third-party analytics platforms.

That's it! You have now completed the Faster Car Race tutorial and have a complete racing game with AdMob integration.
