1.Calculate scalar distance between point A to point B

var moveDirection: Vector3 = (B - A).normalized;
var distance: float = (B - A).magnitude;

  1. use Mathf.PingPong(…) interpolate this distance over time

    var pingpongDistance: float = distance * Mathf.PingPong(Time.time, 1);

  2. calculate position of object

    gameObject.transform.position = A + moveDirection * pingpongDistance;
