Yet another NullReferenceException question.

Edit: I figured out this problem, but I have a new problem I stated at bottom of post

Ok, its my first time programming a game and I'm following a tutorial, but changing the scripts I made following it around to match my game.

I'm trying to script a melee attack, and while I get no errors and can press play and the particles from the melee script are instantiated, no damage is actually done, and the log gets spammed with

NullReferenceException: Object reference not set to an instance of an object AbilitySystem.checkFireValues () (at Assets/Custom Assets/Scripts/Player/AbilitySystem.js:30) AbilitySystem.Update () (at Assets/Custom Assets/Scripts/Player/AbilitySystem.js:23)

I have tried changing it around it seems a hundred times, so I came here to see for some advice. Any help is very much appreciated! :)

MeleeAttack.js

  var countdown : int = 2;

  var playerAttackRange : int = 2;

  var particle : GameObject;

  var player : GameObject;

  function Start () {

  }

  function Update () {

      var particleClone = particle;

      if(countdown > 0){

          countdown -= Time.deltaTime;

          }

      if(countdown <= 0){

          countdown = 2;

          }

      if(Input.GetButton("Fire1")){

          particleClone = Instantiate(particle,

transform.position, transform.rotation); Destroy(particleClone, 1); attack(); }

  }

  function attack(){

      if(AbilitySystem.fireElement.equippedFire

== true) {

      var hit : RaycastHit;

      var fwd = transform.TransformDirection

(Vector3.forward);

      if(Physics.RayCast (transform.position, fwd, hit,

playerAttackRange)){ if(hit.collider.gameObject == null){ Debug.Log("collided with "+hit.name+" which has no DamageManagement!"); }else{ if(hit.collider.gameObject.tag == "Enemy") { hit.collider.gameObject.GetCompponent(EnemyHealth).enemyCurrentHealth -= AbilitySystem.fireElement.swordDamage; } } } } }

AbilitySystem.js

  #pragma strict

  function Start () {

  }

  class fireElementClass {

      var equippedFire : boolean = true;

      var fireLevel : int = (swordLevel + plummetLevel + meteorLevel)/3;

      var swordLevel : int = 1;

      var plummetLevel : int = 1;

      var meteorLevel : int = 1;

      var swordDamage : int = 1;

  }

  static var fireElement : fireElementClass;

  function Update () {

      checkFireValues();

  }

  function checkFireValues(){

      fireElement.swordDamage *= Statistics.levelModifier *

((fireElement.fireLevel * fireElement.swordLevel)/2);

  }

I wanted to figure it out myself... but I concede defeat >_>

Edit: OK, well I figured that part out, now when I use my melee attack, apparently there is some error with the Physics.Raycast
