Load Prefabs in Array with Javascript

Question

During the past few hours, I was trying to load prefabs into an array -.- Maybe I need some help :P

When I use a normal variable like...

 private var temp : GameObject;
 temp = Resources.Load("MyPrefab");

...everything works fine. But when I try to load the same prefab into an array like this...

 private var temp : GameObject[];
 temp[0] = Resources.Load("MyPrefab");

..I get the following error:

 NullReferenceException: Object reference not set to an instance of an object

You haven't created any space for the game object in the array. That is 'temp' is a pointer that has not be initialized. If you know the number of entries that you will be filling, then you can create space this way:

 private var temp : GameObject[] = new GameObject[5];

If you don't know the number of entries you will need, then you can use a .NET generic List.

For more info on Arrays and Collections (including generic Lists) see:
