  1. PONull Reference Exception in Unity game engine
    text
    copied!<p>I am trying to go through a tutorial on Unity (Will Goldstone's book 3.x Game Development Essentials) and keep running into an error messages and I just can't figure out what is wrong with my code. It's from Chapter 5, I am writing this in Javascript. For what i can see I have everything correct--the null reference comes up in my OpenDoor function line 2 &amp; in my shutDoor function line2.:</p> <blockquote> <p>Null Reference Exception PlayerCollisionsjs.OpenDoor(UnityEngine.GameObject door) (at Assests/Scripts /PlayerCollisionsjs.js: 47 **and 37 the lines refecenced below).</p> </blockquote> <p>What am I missing? My <code>OpenDoor</code> &amp; <code>CloseDoor</code> sounds are loaded and the code works if I remove the shut Door requests...any thought </p> <pre><code>#pragma strict private var doorIsOpen : boolean = false; private var doorTimer : float = 0.0; private var currentDoor : GameObject; var doorOpenTime : float = 3.0; var doorOpenSound : AudioClip; var doorShutSound : AudioClip; function Start () { } function Update () { if(doorIsOpen) { doorTimer += Time.deltaTime; if(doorTimer &gt; doorOpenTime) { shutDoor(currentDoor); doorTimer = 0.0f; } } } function OnControllerColliderHit(hit : ControllerColliderHit){ if(hit.gameObject.tag == "playerDoor" &amp;&amp; doorIsOpen == false) { currentDoor == hit.gameObject; OpenDoor(hit.gameObject); OpenDoor(currentDoor); } } function OpenDoor(door: GameObject) { doorIsOpen = true; door.audio.PlayOneShot(doorOpenSound); door.transform.parent.animation.Play("dooropen"); } function shutDoor(door : GameObject) { doorIsOpen = false; door.audio.PlayOneShot(doorShutSound); door.transform.parent.animation.Play("doorshut"); } </code></pre> <p>I did see that someone else got stuck on the same code, but we don't have the same problem, my audio works before I insert the shutDoor function.</p>
