How could I instantiate to a GameObject variable in a class?

Question

class GaragesClass {

 var unit : GameObject = new GameObject();

var unit : GameObject;

private var floors : int = 12;
private var garages : GaragesClass[] = new GaragesClass[floors];

private var baseHeight : float = -2;
private var height = 16.66666;

function Awake () {

 for (var i : int = 0; i&lt;floors; i++) {
     garages[i].unit = Instantiate(unit, Vector3(0, baseHeight*height+i*height, 0), Quaternion.identity);
 }

Instantiating gives the error "Object reference not set to an instance of an object"

You just forgot to instantiate your array elements. add this line

garages[i] = new GaragesClass();

at the beginning of the for loop, and it's gonna work.

Thank you, it worx! Is it because the assignment "new" doesn't work outside a function? Because at the beginning I already wrote

"private var garages : GaragesClass[] = new GaragesClass[floors];"

You do need that lines, it create a an array of empty objects (and specify the size by the way), but each ones inside need to be built too. So you need both.
