Level Rotator (Unity Game) – hyper casual game

Introduction

The Level Rotator is a crucial component in Unity games, particularly in hyper-casual games where the level design plays a significant role in player engagement. The Level Rotator is used to rotate the game scene to create a sense of dynamism and challenge. In this tutorial, we will explore how to use the Level Rotator in Unity to create an engaging and addictive game.

Step 1: Creating a New Project

To start, create a new project in Unity by going to File > New Project. Choose the 2D or 3D template, depending on your game's requirements.

Step 2: Setting up the Game Object Hierarchy

In this tutorial, we will use a simple 2D game with a Player object and Platform objects. Create the following game objects and add them to the scene:

• Player (a 2D sprite)
• Platform1 (a 2D sprite)
• Platform2 (a 2D sprite)
• Platform3 (a 2D sprite)

Arrange the platforms in a way that creates a challenging level for the player to navigate.

Step 3: Creating the Level Rotator

To create the Level Rotator, we will use a script. In the Unity Editor, go to Window > C# Script and create a new script. Name the script LevelRotator.

Open the script and add the following code:

using UnityEngine;

public class LevelRotator : MonoBehaviour
{
    public float rotationSpeed = 5f;
    public bool isRotating = false;

    private float angle = 0f;
    private float targetAngle = 0f;

    void Update()
    {
        if (isRotating)
        {
            angle += rotationSpeed * Time.deltaTime;
            targetAngle = Mathf.Repeat(angle, 360f);
            transform.eulerAngles = new Vector3(0f, 0f, targetAngle);
        }
    }

    public void RotateLevel(float angle)
    {
        isRotating = true;
        targetAngle = angle;
    }

    public void StopRotating()
    {
        isRotating = false;
    }
}

This script will rotate the level by changing the transform.eulerAngles property of the game object.

Step 4: Adding the Level Rotator to the Scene

Drag and drop the LevelRotator script onto the Player game object.

Step 5: Rotating the Level

To rotate the level, call the RotateLevel method and pass the desired angle as a parameter. For example:

LevelRotator levelRotator = GetComponent<LevelRotator>();
levelRotator.RotateLevel(90f);

This will rotate the level by 90 degrees.

Step 6: Stopping the Rotation

To stop the rotation, call the StopRotating method:

levelRotator.StopRotating();

Step 7: Creating a Level Transition

To create a level transition, you can use a state machine or a finite state machine (FSM) to manage the game states. For example, you can create a LevelTransition state that triggers the rotation of the level.

Step 8: Testing the Level Rotator

Test the level rotator by running the game and rotating the level. You can use the RotateLevel method to rotate the level, and the StopRotating method to stop the rotation.

Conclusion

In this tutorial, we have learned how to use the Level Rotator in Unity to create a challenging and engaging game. The Level Rotator can be used to rotate the game scene, creating a sense of dynamism and challenge. By following these steps, you can create a simple level rotator that can be used in your game.
