Intro to Shooter Mechanics - Small Copy/Paste error

http://unity3d.com/learn/tutorials/topics/scripting/intro-shooter-mechanics

Looks like a couple likes are repeated on the code, can some one remove it. It causes small compile error.

 

Morning,

Might be better to post in the live training so the author has a better chance of seeing it.
but @Matthew Schell may be able to resolve.

 

@playa1337 thanks for the tip, I'll tidy it up.

 

Hello,
I've just finished watching the "intro to shooter mechanics" and I get this little error saying that :
In "RayCastShooterScript":
void Update ()
{
RaycastHit hit;
Vector3 rayOrigin = fpsCam.ViewportToWorldPoint(new Vector3 (.5f, .5f, 0)); //NullReferenceException: Object reference not set to an instance of an object

I've opened a new script, attached to the "parent" of the whole FPS shooter, gun end and the rest.
And I can't figure out what object is the missing object. I 've checked the script and copy-passed the script.
I've started a new proj. and the error came back.

Hope there's a simple solution
Thank you!
