     enemyHealthText.text = "Enemy Hp " + enemyHealth;
     if(this.enemyHealth <= 0) {
         PlayerHealth.curXp += 0;
         Destroy(this.gameObject);
     }
 }
   
 function OnTriggerStay (col : Collider) {
     if(col.gameObject.tag == "attackArea") {
         if(Input.GetKeyDown("1")) {
             var randomDamage = (UnityEngine.Random.Range(PlayerHealth.minAttack.PlayerHealth.maxAttack)) * PlayerHealth.attackPower;
             this.enemyHealth -= randomDamage;
