How to do Damage During Animation When Enemy Enters Range? - unity3d

Question

2D Top Down style game. I’m trying to figure out how to hit an enemy whenever he enters the range of my attack point and get hit every, say, 3 frames if he is still within my attack point. here's my script.
public Animator animator;
public Transform AttackPoint;
public float attackRange = 0.5f;
public LayerMask enemyLayers;
public int attackDamage = 40;
public float attackRate = 1f;
float nextAttackTime = 0f;
// Update is called once per frame
void Update()
{
if(Time.time >= nextAttackTime)
{
if (Input.GetKeyDown(KeyCode.Space))
{
Attack();
nextAttackTime = Time.time + 1f / attackRate;
}
}
}
void Attack()
{
animator.SetTrigger("Attack");
Collider2D[] hitEnemies = Physics2D.OverlapCircleAll(AttackPoint.position, attackRange, enemyLayers);
foreach(Collider2D enemy in hitEnemies)
{
enemy.GetComponent<Enemy>().TakeDamage(attackDamage);
}
}
void OnDrawGizmosSelected()
{
if (AttackPoint == null)
return;
Gizmos.DrawWireSphere(AttackPoint.position, attackRange);
}

foreach enemys and check distance with you , and attack it.
and you need a Manager to handle all enemys.
List<Transform> enemys = new List<Transform>();
public void Update()
{
for (int i = 0; i < enemys.Count; i++)
{
float distance = Vector3.Distance(enemys[i].position, transform.position);
if (distance < 10)// in range
{
//todo attack
}
}
}
