What am I getting this error for?

Unity Engine

I have a script that makes 4 different game object appear when the player looks in a certain direction, but I’m getting a strange error. Here’s the script…

var player : GameObject;
var north : GameObject;
var south : GameObject;
var east : GameObject;
var west : GameObject;
var yRotation : float = 5.0;

function Update () {

yRotation += Input.GetAxis("Horizontal");

if(player.transform.eulerAngles.y <= 45 && player.transform.eulerAngles.y > 315)
    {
    north.SetActive (true);
    south.SetActive (false);
    east.SetActive (false);
    west.SetActive (false);
    }

if(player.transform.eulerAngles.y <= 315 && player.transform.eularAngles.y > 225)
    {
    north.SetActive (false);
    south.SetActive (false);
    east.SetActive (false);
    west.SetActive (true);
    }

if(player.transform.eulerAngles.y <= 225 && player.transform.eulerAngles.y > 135)
    {
    north.SetActive (false);
    south.SetActive (true);
    east.SetActive (false);
    west.SetActive (false);
    }

if(player.transform.eulerAngles.y <= 135 && player.transform.eulerAngles.y > 45)
    {
    north.SetActive (false);
    south.SetActive (false);
    east.SetActive (true);
    west.SetActive (false);
    }
}

But I get this odd error. Even stranger is that it’s only on line 20, even though there are a few lines that have nearly the same thing. Here’s the error…

NullReferenceException: Object reference not set to an instance of an object
Boo.Lang.Runtime.RuntimeServices.GetDispatcher (System.Object target, System.String cacheKeyName, System.Type[ ] cacheKeyTypes, Boo.Lang.Runtime.DynamicDispatching.DispatcherFactory factory)

Boo.Lang.Runtime.RuntimeServices.GetProperty (System.Object target, System.String name)
UnityScript.Lang.UnityRuntimeServices.GetProperty (System.Object target, System.String name)
Compass.Update () (at Assets/Compass.js:20)

What can I do?

You spelled the second “Euler” wrong on line 20.

Oh :smile:! Oops.
