2.5D Rotating Tower Effect For Platformers

In this tutorial we take a look at how to make a 2.5D Rotating Tower effect for a platformer game. This effect was made famous in games like ‘Mickey Mania’ and ‘Porky Pig’s Haunted Holiday’ and historically required some creative trickery to pull off. Now, using 3D objects alongside a 2D character it is really easy to create a similar effect quickly and easily.

These are the scripts used in the level:

TreeTurn.cs

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class TreeTurn : MonoBehaviour
{
    public float speed = 1;

    void FixedUpdate()
    {
        float moveHorizontal = Input.GetAxis("Horizontal");
        transform.Rotate(0.0f, Input.GetAxis("Horizontal") * speed, 0.0f);
    }
}
