Newbie Question | How to limit movement range of gameobject with sending ray and find tag..

Unity Engine

Hello guys im trying to create limit for movement range of my player. I set tag for ground and target for buildings. I want only move my object if ray hit ground. But i have problem about it.
In this picture, when i clicked the intersection between ground and building object still running. How can i handle this problem? I think i need to change this part of code because every object intersection with plane make my object running. ( Intersection part shown as yellow in picture)

Plane plane = new Plane(Vector3.up, transform.position);
        Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
        float point = 0f;

    void Update()
    {
        ConsumeEnergy();
        if (Input.GetMouseButton(LEFT_MOUSE_BUTTON))
            SetTargetPosition();
        if (isMoving)
            CowMovement();

    }

        public void SetTargetPosition()
    {
        Plane plane = new Plane(Vector3.up, transform.position);
        Ray ray = Camera.main.ScreenPointToRay(Input.mousePosition);
        float point = 0f;


            if (plane.Raycast(ray, out point) && hit.collider.gameObject.tag == "Ground")
            {
                targetPosition = ray.GetPoint(point);
                isMoving = true;
            }
        
    }

    // ------------------------------------------- Part VI ------------------------------------------------

    public void CowMovement()
    {
        transform.LookAt(targetPosition);
        transform.position = Vector3.MoveTowards(transform.position,
                                                 targetPosition,
                                                 speed * Time.deltaTime);

        {
            if (transform.position == targetPosition)
            {
                isMoving = false;
            }
        }

        Debug.DrawLine(transform.position, targetPosition, Color.red);

    }

isMoving=false; //you forgot to set moving to false
 foreach (RaycastHit hit in hits){
            if (plane.Raycast(ray, out point) && hit.collider.gameObject.tag == "Ground")
            {
                targetPosition = ray.GetPoint(point);
                isMoving = true;
break; //cancel loop for better performance
            }
} //use brackets

problem solved?
