Move Objects with Scroll Input in Unity

Welcome to this Unity tutorial where you'll learn how to implement object movement based on scroll input. This can add a dynamic and interactive element to your game. Let's dive into the steps.

Step 1: Create a Unity Project

If you haven't yet, begin by opening Unity and creating a new 3D project. Ensure you have the necessary assets installed for your preferred development environment.

Step 2: Import Object

Import or create the object you want to move in your scene. This could be a character, a camera, or any other element that you want to respond to scroll input.

Step 3: Write Scroll Input Logic

Create a new C# script and inside the script, implement the logic to detect scroll input and adjust the object's position accordingly. Use the 'Input.GetAxis("Mouse ScrollWheel")' to get the scroll input.

'ScrollMovement.cs'

using UnityEngine;

public class ScrollMovement : MonoBehaviour
{
    public float scrollSpeed = 5.0f;

    void Update()
    {
        float scrollInput = Input.GetAxis("Mouse ScrollWheel");
        Vector3 newPosition = transform.position + Vector3.up * scrollInput * scrollSpeed;

        // Adjust the object's position
        transform.position = newPosition;
    }
}

Step 4: Add Scroll Script

Attach the C# that contains the moving logic to the object you want to move.

Step 5: Adjust Scroll Speed

In the Unity Editor, you can adjust the 'scrollSpeed' variable in the script to control the sensitivity of the scroll movement.

Step 6: Test Your Game

Run your game and test the object movement by scrolling up and down. The object should respond to the scroll input, providing a smooth and interactive experience.
