follow camera that rotates when i change direction

Hi everyone !

I need a third person camera that smoothly rotates around the player object when i change the direction the player object is going (rolling) in with the arrow keys. The player object in this case is a rolling ball where i've added forces to the axis. I found this script and tried it:

using UnityEngine; using System.Collections;

public class FollowCam : MonoBehaviour { public GameObject target; public float damping = 1; Vector3 offset;

 void Start() 
 {
     offset = target.transform.position - transform.position;
 }
 
 void LateUpdate() {
     float currentAngle = transform.eulerAngles.y;
     float desiredAngle = target.transform.eulerAngles.y;
     float angle = Mathf.LerpAngle(currentAngle, desiredAngle, Time.deltaTime * damping);
     
     Quaternion rotation = Quaternion.Euler(0, angle, 0);
     transform.position = target.transform.position - (rotation * offset);
     
     transform.LookAt(target.transform);
 }

}

but the camera just keep rotating between two axis continuesly. Is there a way to clamp the camera to an angle or something ? can't get my head around this one.

if anyone have any suggestions, please share :)
