How would I add rotation limits to this?

I have the following script that I use to have my character’s head face the target. However an error has come up where I’ve noticed that I don’t currently have any limits for the rotation and so the character’s head will regularly recreate scenes from the exorcist in order to look at the target. How would I set max/min limits to the various axis?

using UnityEngine;
using System.Collections;

public class LookAtSlow : MonoBehaviour {
	public Transform target;
	public float degreesPerSecond;

	// Update is called once per frame
	void Update () {

		// The difference between target position and our position yields a direction
		Vector3 dirFromMeToTarget = target.position - transform.position;

		// Calculates a rotation where the direction 'dirFromMeToTarget' would be forward
		Quaternion lookRotation = Quaternion.LookRotation(dirFromMeToTarget);

		// Lerp from our current rotation to the desired 'lookRotation' at a rate of 'degreesPerSecond'
		transform.rotation =
			Quaternion.Lerp(transform.rotation, lookRotation, Time.deltaTime * (degreesPerSecond/360.0f));
	}
}

Hey there. I think a ‘Clamp’ might do the trick. Try having a look at this page here ‘Unity - Scripting API: Mathf.Clamp’ and see if that’s what you’re looking for :smiley:
