rotate until he look at something

Questions & Answers

i'm trying to create a simple cutscene, how can i tell to the object to rotate until it looks at something, or to rotate only when it's angle is < of something

it's my script for now

 transform.Rotate(Vector3.up * Time.deltaTime * 18);

The easiest way is `transform.LookAt()`. Then your character will face the object. You could also use `Quaternion.LookRotation()` then check to see when that angle matches the player's angle.

You can use Quaternion.LookRotation to find the rotation required to make your object look in a specific direction or at a specific point.

You can then use Quaternion.RotateTowards to make your object gradually rotate towards that rotation.

I know the post is kind of old, but it helped me, and this is how I solved this question:

#pragma strict

var target : Transform;
var speed: float; 

function Update () {
	// find Rotation towards target
	var relativePos = target.position - transform.position;
    var rotation = Quaternion.LookRotation(relativePos);
	
    // Rotate our transform a step closer to the target's.
    var step = speed * Time.deltaTime;
    transform.rotation = Quaternion.RotateTowards(transform.rotation, rotation, step);
}
