how can i set target(gameobject) from string(name)

im trying to set a target from a string or perhaps another way to set target when it loads in game heres my enemy attack script so far the target im looking for is a gameobject my player character when i load in game im able to add the target when game is running but i need it to auto add from the string name if possible

using UnityEngine; using System.Collections;

public class EnemyAttack : MonoBehaviour { public GameObject target; public float attackTimer; public float coolDown;

 public string enemyattacktargetname;
 // Use this for initialization
 void Start () {
     attackTimer = 0;
     coolDown = 2.0f;
 }
 
 // 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);
     
     if(distance < 2.5f) {
         
         if(direction > 0) {
             PlayerHealth eh = (PlayerHealth)target.GetComponent("PlayerHealth");
             eh.AddjustCurrentHealth(-10);
         
         }
         if (target = null)
         PlayerHealth.DontDestroyOnLoad(PlayerHealth);
     }
 }

}
