LookRotation Between 2 Points

Questions & Answers
1

Basically I am trying to get an object to look at one object or a specific rotation, then smoothly switch to another rotation or object, and to continuously loop.

I have written a small script that i think is on the right track for working using Co-routines.

	public Transform pointB;
	public Transform pointC;
	
	public IEnumerator TurretLook (Transform thisTransform, Quaternion startAngle, Quaternion endAngle, float time)
	{
		float i = 0.0f;
		float rate = 1.0f / time;
		while (i < 1.0) {
			i += Time.deltaTime * rate;
			thisTransform.rotation = Quaternion.Lerp (startAngle, endAngle, i);
			yield return new WaitForSeconds(0);
		}
	}
	
	IEnumerator Start ()
	{
		Quaternion pointA = transform.rotation;
		while (true) {
			yield return TurretLook(transform, pointA, Quaternion.LookRotation (pointB.position - transform.position), 3.0f);
			yield return TurretLook(transform, pointA, Quaternion.LookRotation (pointC.position - transform.position), 3.0f);
		}
	}

Ended up Rewriting the Script. Posting Here in case anyone else might want this solution as well.

Uses 2 Empty Gameobjects with colliders attached to detect when the ray-cast intersects with one, then switched states to target the opposite.

using UnityEngine;
using System.Collections;

public class MainMenuTurret : MonoBehaviour 
{
	private float aimSpeed;
	public float dampening;
	public Transform[] points;
	
	public enum Target{
		point1,
		point2
	};
	
	public Target tState;
	
	public void MenuIdle ()
	{
		Ray idle = new Ray (transform.position, transform.forward);
		RaycastHit hit;
		
		Debug.DrawRay(idle.origin, idle.direction * 5, Color.blue);
		
		if (Physics.Raycast (idle, out hit, 5)) {
			GameObject hitObj = hit.collider.gameObject;
			
			if (hitObj.tag == "P1")
				tState = Target.point2;
			if (hitObj.tag == "P2")
				tState = Target.point1;
		}
	}
	
	void Update ()
	{
		aimSpeed = dampening * Time.deltaTime;
		
		MenuIdle ();
		
		switch (tState) {
		case Target.point1:
			transform.rotation = Quaternion.Lerp (transform.rotation, Quaternion.LookRotation (points [0].position - transform.position), aimSpeed);
			break;
			
		case Target.point2:
			transform.rotation = Quaternion.Lerp (transform.rotation, Quaternion.LookRotation (points [1].position - transform.position), aimSpeed);
			break;
			
		}
	}
}
