Hi. Here's my code:

var colliders : Collider[] = Physics.OverlapSphere (transform.position, 3);
   for (var hit in colliders) {
   if (hit.transform.parent.tag == "EnemyShip" || hit.transform.parent.tag == "EnemyGround") {
   hit.transform.parent.GetComponent("enemyShipScript").takeDamage(bulletDamage);
   print("Hit!");
   }
} 

My problem is that it prints "Hit!" for every collider that the enemy has. My enemies have several colliders. How do I limit it so that it only applies the damage once per enemy?
