Hello, im doing my first game and im trying to detect the enemies inside an circle area around my player. I have two problems right now

-When a start the game, the circlecollider and player collider is detected as enemies even when i use the compare tag “Enemy”

-My corroutine dont refresh every 2s, and only detect colliders one time when the game start

public class ItemDamage : MonoBehaviour
{
    [SerializeField] int damage;
    [SerializeField] Collider2D[] objectsInsideArea;
    Vector2 radiusOfDamage;
    int radius;
    public void Start()
    {
        radiusOfDamage = new Vector2(radius, 0f);
        StartCoroutine(DamageEnemy());
    }
 
    bool IsEnemy(string tag)
    {
        for (int i = 0; i < objectsInsideArea.Length; i++)
            if (objectsInsideArea*.gameObject.CompareTag("Enemy"))*

{
Debug.Log(“object {i} is an Enemy”);
return true;
} else
{
Debug.Log(“object {i}”);
}
return false;
}

IEnumerator DamageEnemy()
{
objectsInsideArea = Physics2D.OverlapAreaAll(Vector2.zero, radiusOfDamage);
foreach (bool IsEnemy in objectsInsideArea)
{
Debug.Log(“You damage the enemy”);
}
yield return new WaitForSeconds(2);
}
}

Q: When a start the game, the circlecollider and player collider is detected as enemies even when i use the compare tag “Enemy”

A: Logic is not correct

 private bool IsEnemy(Collider2D col)
    {
        if (col.gameObject.CompareTag("Enemy"))
        {
            Debug.Log("object {i} is an Enemy");
            return true;
        }

        Debug.Log("object {i}");
        return false;
    }

Q: My corroutine dont refresh every 2s, and only detect colliders one time when the game start

A: Recall your coroutine after 2 seconds inside coroutine (recursive)

IEnumerator DamageEnemy()
     {
         objectsInsideArea = Physics2D.OverlapAreaAll(Vector2.zero, radiusOfDamage);
          foreach (var col in objectsInsideArea)
          {
             if (!IsEnemy(col)) continue;
             Debug.Log("You damage the enemy");
           }

         yield return new WaitForSeconds(2);
         StartCoroutine(DamageEnemy());
     }
