Need him doing tasks and facing the right way

I need him to face whatever direction he’s walking in This is a 2D platformer. I also want him to randomly do tasks around a village using System.Collections; using System.Collections.Generic; using UnityEngine;

/// /// This makes an object move randomly in a set of directions, with some random time delay in between each decision /// public class Wanderer : MonoBehaviour { internal Transform thisTransform;

 // The movement speed of the object
 public float moveSpeed = 1f;

 // A minimum and maximum time delay for taking a decision, choosing a direction to move in
 public Vector2 decisionTime = new Vector2(1, 4);
 internal float decisionTimeCount = 0;

 // The possible directions that the object can move int, right, left, up, down, and zero for staying in place. I added zero twice to give a bigger chance if it happening than other directions
 internal Vector3[] moveDirections = new Vector3[] { Vector3.right, Vector3.left, Vector3.zero, Vector3.zero };
 internal int currentMoveDirection;

 // Use this for initialization
 void Start()
 {
     // Cache the transform for quicker access
     thisTransform = this.transform;

     // Set a random time delay for taking a decision ( changing direction, or standing in place for a while )
     decisionTimeCount = Random.Range(decisionTime.x, decisionTime.y);

     // Choose a movement direction, or stay in place
     ChooseMoveDirection();
 }

 // Update is called once per frame
 void Update()
 {
     // Move the object in the chosen direction at the set speed
     thisTransform.position += moveDirections[currentMoveDirection] * Time.deltaTime * moveSpeed;

     if (decisionTimeCount > 0) decisionTimeCount -= Time.deltaTime;
     else
     {
         // Choose a random time delay for taking a decision ( changing direction, or standing in place for a while )
         decisionTimeCount = Random.Range(decisionTime.x, decisionTime.y);

         // Choose a movement direction, or stay in place
         ChooseMoveDirection();
     }
 }

 void ChooseMoveDirection()
 {
     // Choose whether to move sideways or up/down
     currentMoveDirection = Mathf.FloorToInt(Random.Range(0, moveDirections.Length));
 }
