 var dist: float = Vector3.Distance(player.transform.position, target.transform.position);
 if (dist < damageDist){
     hitpoints -= damagePerSecond * Time.deltaTime;
 }

or (because it doesn't use square roots ---> faster)

 var distVec: Vector3 =  player.transform.position - target.transform.position;
 var distSqr: float = distVec.sqrMagnitude;
 if (distSqr < damageDist * damageDist){
     // same as other one
 }
