Instantiate transformation?

When you instantiate an object, is there anyway to add a transformation to the object (so you can create an exploding type effect) using the script that is instantiating the object? Or would you have to attach a separate script to the prefab that you are going to instantiate (if that is the case. how can you instantiate objects and make the objects face a random direction)?

All GameObjects have a Transform so you don't need to add one. You can specify the position and rotation inside the Instantiate function like this:

var prefab : GameObject;
Instantiate(prefab,, Random.rotation);

If you use a variable you have access to the components of the object, e.g.:

var clone : GameObject;
clone = Instantiate( ... );  
clone.transform =
