Detecting Enemies inside Area,Detecting Enemies inside Circle

Question

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[i].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);
     }
 }

For radiusOfDamage you can just store it as a float

If you want circle detection then you should be using Physics2D.OverlapCircleAll(); instead of Physics2D.OverlapAreaAll(); which uses a Rectangular area.

I covered several methods of Finding Targets in this tutorial video https://unitycodemonkey.com/video.php?v=h9oEhVqGptU

For your coroutine, if you want it to run forever every 2 seconds then you need to put a while (true) inside it otherwise it will only run once.

 IEnumerator DamageEnemy()
  {
    while (true) {
      objectsInsideArea = Physics2D.OverlapCircleAll(transform.position, radiusOfDamage);
      foreach (bool IsEnemy in objectsInsideArea)
      {
          Debug.Log("You damage the enemy");
      }
      yield return new WaitForSeconds(2);
  }
 }

i didnot realize that Vector2.zero is global and not local on gameobject. Enemies only got detected when they were in origin. Made some changes to code and now is working 100%. Thanks for the reply!!!
