how to move npc back and forth between boxes

[anon20000101]

I am trying to move my npc between boxes rather then going through it.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;

public class Patrol : MonoBehaviour
{

    public float speed;
    public float distance;
    private bool movingRight = true;
    public Transform groundDetection;

    void Update()
    {

        transform.Translate(Vector2.left * speed * Time.deltaTime);

        RaycastHit2D groundInfo = Physics2D.Raycast(groundDetection.position, Vector2.down, 2.0f, LayerMask.GetMask("Ground"));

        if (groundInfo.collider == false)
        {
            if (movingRight == true)
            {
                transform.eulerAngles = new Vector3(0, -180, 0);
                movingRight = false;
            }
            else
            {
                transform.eulerAngles = new Vector3(0, 0, 0);
                movingRight = true;
            }
        }

    }
   

}
