Up Down – (Unity Game) Simple Hyper Casual Game For Android And iOS

Introduction

Welcome to this tutorial on creating a simple hyper-casual game using Unity, titled "Up Down". This game is a basic arcade-style game where the player has to tap the screen to control a ball that bounces up and down a grid. The goal is to prevent the ball from hitting the bottom of the screen for as long as possible, earning points and trying to beat the high score.

In this tutorial, we will cover the process of creating this game from scratch, including setting up the game environment, designing the game mechanics, and publishing the game on both Android and iOS platforms.

Pre-requisites

• Unity version 2019.4 or later
• Basic understanding of C# programming language
• Android and iOS development knowledge is not required, as we will cover the setup and publishing process in detail
• A computer or laptop with Unity installed

Creating the Game

Step 1: Create a New Unity Project

1. Open Unity and click on "New" to create a new project.
2. Choose a project name, project location, and select "3D" as the game type (even though we'll be creating a 2D game).
3. Choose a template, or create a new project from scratch.

Step 2: Set up the Game Environment

1. In the Unity editor, navigate to the "GameObject" menu and select "2D Object" > "Empty" to create a new empty game object.
2. Name this object "Game" and make it the parent of all other game objects.
3. Create a new material for the game background by clicking on "Window" > "Material Editor".
4. Create a new sprite by clicking on "Sprites" > "Default Assets" > "Texture" > "New Sprite" and name it "background".
5. Apply the background material to the Game object.

Step 3: Create the Ball Object

1. Navigate to the "GameObject" menu and select "2D Object" > "Circle" to create a new circle game object.
2. Name this object "Ball" and position it at the top center of the screen.
3. Create a new sprite by clicking on "Sprites" > "Default Assets" > "Texture" > "New Sprite" and name it "ball".
4. Apply the ball sprite to the Ball object.

Step 4: Add the Ball Script

1. Navigate to the "Assets" > "Scripts" folder and create a new C# script by clicking on "C#" > "New C# Script" and naming it "BallScript".
2. Attach the BallScript to the Ball object by dragging and dropping it onto the Ball game object in the Hierarchy panel.
3. Open the BallScript and add the following code:

   
   using UnityEngine;

public class BallScript : MonoBehaviour { public float speed = 1f; public float maxHeight = 5f;

private Vector3 pos;

void Start()
{
    pos = transform.position;
}

void Update()
{
    pos.y += speed * Time.deltaTime;
    if (pos.y > maxHeight)
    {
        pos.y = -pos.y;
    }
    transform.position = pos;
}

}

This script will control the ball's movement and prevent it from going below the maximum height.

Step 5: Add the Input Script

1. Navigate to the "Assets" > "Scripts" folder and create a new C# script by clicking on "C#" > "New C# Script" and naming it "InputScript".
2. Attach the InputScript to the Game object by dragging and dropping it onto the Game game object in the Hierarchy panel.
3. Open the InputScript and add the following code:
```csharp
using UnityEngine;

public class InputScript : MonoBehaviour
{
    public float tapForce = 1f;

    private BallScript ballScript;

    void Start()
    {
        ballScript = GameObject.Find("Ball").GetComponent<BallScript>();
    }

    void Update()
    {
        if (Input.GetTouch(0).phase == TouchPhase.Began)
        {
            ballScript.speed += tapForce;
        }
        else if (Input.GetTouch(0).phase == TouchPhase.Ended)
        {
            ballScript.speed -= tapForce;
        }
    }
}

This script will control the player's input and adjust the ball's speed accordingly.

Publishing the Game

Step 1: Create a Build Configuration

1. Navigate to the "Edit" > "Project Settings" > "Player" menu and select "Android" or "iOS" as the target platform.
2. Set the bundle identifier and package name (for Android) or app ID (for iOS).

Step 2: Export the Game

1. Navigate to the "File" > "Build Settings" menu and select the target platform.
2. Set the build location and save the build configuration.

Conclusion

In this tutorial, we have covered the process of creating a simple hyper-casual game using Unity, including setting up the game environment, designing the game mechanics, and publishing the game on both Android and iOS platforms. With this knowledge, you can create your own hyper-casual games and publish them on multiple platforms.
