Lerp Rotation Of A 3D Object Using C# Scripts In Unity

Introduction

In this article, we will discuss Lerp rotation of a 3D object using C# scripts in Unity.

Prerequisites

Unity environment version 2017.4.39f1

Create the Project:

First, you have to open the Unity project. Create the plane.

Click on the "GameObject" menu in the menu bar. Select 3D objects and pick the "cube" option. The cube will be added to the scene View

Drag and drop the black and red material. The color of the cube will be changed into black and red.

Create a C# Script

Right-click on Assets. Select Create >> C# script.

Rename the script as Lerprotation.

Double click on the Lerprotation script. The MonoDevelop-Unity editor will open up.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
public class Lerprotation: MonoBehaviour {
[SerializeField][Range(0 f, 5 f)] float lerptime;
[SerializeField] Vector3[] myAngels;
int angleIndex;
int len;
float t = 0 f;
// Use this for initialization
void Start() {
len = myAngels.Length;
}
// Update is called once per frame
void Update() {
transform.rotation = Quaternion.Slerp(transform.rotation, Quaternion.Euler(myAngels[angleIndex]), lerptime * Time.deltaTime);
t = Mathf.Lerp(t, 1 f, lerptime * Time.deltaTime);
if (t > .9 f) {
t = 0 f;
angleIndex = Random.Range(0, len - 1);
}
}
}
