4 directional animation ai 2d

im trying to get my ai to play the correct animation when they move, so if they move left they play the walking left animation. I have looked all over the internet for over a month now and have gotten nothing. here is my script.

 using System.Collections;
 using System.Collections.Generic;
 using UnityEngine;
 
 public class EnemyMovement : MonoBehaviour
 {
     public Transform player;
     public float moveSpeed;
     public bool canMove;                            //whether ai is allowed to move or not
     public float maxDistance;
     public float minDistance;
     public float attackTime;
     public Vector2 lastMove;
     public AnimationClip walking;
 
     private bool enemyMoving;
     private Animator anim;
     private Rigidbody2D myRigidbody;
     private float currentMoveSpeed;
     private float attackTimeCounter;
 
     void Start()
     {
         player = GameObject.FindGameObjectWithTag("Player").transform;
         anim = GetComponent<Animator>();
         myRigidbody = GetComponent<Rigidbody2D>();
         canMove = true;
         
     }
 
     void Update()
     {
         if (Time.timeScale == 0f)
         {
             return;
         }
         if ((Vector2.Distance(transform.position, player.position) < maxDistance)
 && (Vector2.Distance(transform.position, player.position) > minDistance))
         {
             transform.position = Vector2.MoveTowards(transform.position, player.position, moveSpeed * Time.deltaTime);
         }
 
         anim.SetFloat("MoveX", myRigidbody.velocity.x);
         anim.SetFloat("MoveY", myRigidbody.velocity.y);
         anim.SetBool("EnemyMoving", enemyMoving);
         anim.SetFloat("LastMoveX", lastMove.x);
         anim.SetFloat("LastMoveY", lastMove.y);
     }
 }
