Make ANY Object Smoothly Turn or Look At Another Object

Published: 05 Mar 2021

In this tutorial, you'll learn:

⚫ How to make an object smoothly rotate to look at another target without Transform.LookAt().

⚫ How to make Transform.LookAt() rotate an object smoothly.

⚫ When Transform.LookAt() will not be smooth.

To achieve always-smooth look at, we'll implement a Coroutine that rotates any object using Quaternion.LookRotation and Quaternion.Slerp.

If you need to lock the rotation to 1 or 2 axis:

After you've determined the look rotation with Quaternion.LookRotation, reassign it with

lookRotation = Quaternion.Euler(transform.rotation.eulerAngles.x, lookRotation.eulerAngles.y, transform.rotation.eulerAngles.z);

This code will only rotate on the Y axis. You can keep the original rotation on any axis and assign the look rotation for any other axis!

Use this knowledge to add believable turns into your game by having your objects always smoothly turn to look at another object!
