Instantiate a prefab which exists in assets, not in scene

Question

Hope someone can help with this. I have a prefab called 'brick' (it's just a red cube). This prefab is in a folder called 'prefabs' inside my assets folder. It's not in the scene.

In javascript, I'm trying to instantiate the prefab using:

 var brick : Transform;
 function Start () {
     var y = 0; 
     var x = 0; 
             Instantiate(brick, Vector3 (x, y, 0), Quaternion.identity);
         }
     }
 }

But I get the error:

 ArgumentException: The prefab you want to instantiate is null.

What does this mean? – I wish Unity's errors were more n00b-friendly!

I recommend you read about Resources: Resources

But it would be like

 var instance : GameObject = Instantiate(Resources.Load("brick", GameObject));

Brilliant, thank you ARKMs. Works like a charm. I'm using

 var instance : GameObject = Instantiate(Resources.Load(myLitem, GameObject));

Where myLitem is the GameObject I used using the GameObject.find earlier up in the script. One question: Although this works well, the instantiated object always appears at the x y z co-ordinates of 0. One thing I couldn't work out was how would you get the instantiated object to appear at the location of a GameObject? @ARKMs

Actually, just solved it. I used: var instance : GameObject = Instantiate(Resources.Load(myLitem, GameObject),transform.position + Vector3(0,0.2,0),transform.rotation);

Yeah, in you var 'instance' you can instance .transform.position = otherGameObject.position; intance.transform.rotation = otherGameObject.rotation;
