How to make an animation play for AI?

I made a script which makes the AI attack me and decrease my health unfortunately I have no idea on how to get the animation to play with it.

The attack script: using UnityEngine; using System.Collections;

 public class EnemyAttack : MonoBehaviour {
     public GameObject target;
     public float attackTimer;
     public float coolDown;
     
     // Use this for initialization
     void Start () {
         attackTimer = 0;
         coolDown = 1.0f;
     }
     
     // Update is called once per frame
     void Update () {
         if(attackTimer > 0)
             attackTimer -= Time.deltaTime;
             
         if(attackTimer <0)
             attackTimer = 0;
         
             if(attackTimer == 0) {
                 Attack();
                 attackTimer = coolDown;
         }
     }
     private void Attack() {
         float distance = Vector3.Distance(target.transform.position, transform.position);
         
         Vector3 dir = (target.transform.position - transform.position).normalized;
         
         float direction = Vector3.Dot(dir, transform.forward);
         
         Debug.Log(direction);
         
         if(distance < 2.5f) {
             if(direction > 0) {
             PlayerHealth ph = (PlayerHealth)target.GetComponent("PlayerHealth");
             ph.AddjustCurrentHealth(-10);
             }
         }
     }
 }

How do I make an animation work with this?
