NullReferenceException with boolean from other script

I have 2 scripts.

script 1:

var waarde : boolean;

function Awake(){
	waarde = false;
	}

script 2:

var waarde:boolean;
var script1;

function Awake(){
script1 = this.gameObject.GetComponent(script1);
waarde = script1.waarde; <-- NullReference?
}

You can not know which of the objects will be initialize first.
For this reason, you should wait a frame before looking for other objects.

Do this in script 2:

 function Awake()
 {
   StartCoroutine(Initiate());
 }

 private function Initiate()
 {
    yield;
    script1 = this.gameObject.GetComponent(script1);
    waarde = script1.waarde;
 }

You should only setup references in the Awake function. Like the line below is perfect:

script1 = this.gameObject.GetComponent(script1);

As for getting information like the value you want from that boolean. Do that in the Start function of Script 2 instead.

function Start()
{
    waarde = script1.waarde;
}

This is because you cannot be sure that the Awake function of Scrip 1 is called before that of Script 2’s.
