Stealth Tutorial: NullReferenceException with AlarmLight
I'm following the unity stealth tutorials, and running into a "nullreferenceexception: Object Reference not set to an instance of an object" when testing, at the end of chapter 2, lesson 4. pretty deep in, however the compiler highlights problems with a much earlier thread
See my code on pastebin, The line it highlights is line 23.
And here's a picture from the editor which is most likely relevant: 
What did i do wrong, did i make the same mistake several times with other objects too? and what can i do to prevent this in future?
There are a gazillion questions asking about nullreferenceexceptions. FindGameObjectWithTag() failed to find a game object, and your code assumes it did find something.
