Scripting beginner - how can I make the camera follow the character but still face the same direction?

I have a script that follows the character, however it rotates with the character, which is quite annoying since the character appears to be moving forward, but I am actually holding the left arrow key.

C# Smooth Follow script:

 using UnityEngine;
 
 namespace UnityStandardAssets.Utility
 {
     public class SmoothFollow : MonoBehaviour
     {
 
         // The target we are following
         [SerializeField]
         private Transform target;
         // The distance in the x-z plane to the target
         [SerializeField]
         private float distance = 10.0f;
         // the height we want the camera to be above the target
         [SerializeField]
         private float height = 5.0f;
 
         [SerializeField]
         private float rotationDamping;
         [SerializeField]
         private float heightDamping;
 
         // Use this for initialization
         void Start() { }
 
         // Update is called once per frame
         void LateUpdate()
         {
             // Early out if we don't have a target
             if (!target)
                 return;
 
             // Calculate the current rotation angles
             var wantedRotationAngle = target.eulerAngles.y;
             var wantedHeight = target.position.y + height;
 
             var currentRotationAngle = transform.eulerAngles.y;
             var currentHeight = transform.position.y;
 
             // Damp the rotation around the y-axis
             currentRotationAngle = Mathf.LerpAngle(currentRotationAngle, wantedRotationAngle, rotationDamping * Time.deltaTime);
 
             // Damp the height
             currentHeight = Mathf.Lerp(currentHeight, wantedHeight, heightDamping * Time.deltaTime);
 
             // Convert the angle into a rotation
             var currentRotation = Quaternion.Euler(0, currentRotationAngle, 0);
 
             // Set the position of the camera on the x-z plane to:
             // distance meters behind the target
             transform.position = target.position;
             transform.position -= currentRotation * Vector3.forward * distance;
 
             // Set the height of the camera
             transform.position = new Vector3(transform.position.x ,currentHeight , transform.position.z);
 
             // Always look at the target
             transform.LookAt(target);
         }
     }
 }

There is also a LookAt script on the character, which makes the camera look at the character. With the smooth follow script, looks both at the character and moves with it.

JavaScript script for LookAt:

 #pragma strict
 var target: GameObject;
 function Update(){
 transform.LookAt(target.transform.position);
 }
