How can I make an object disappear when clicked?

Just as the ultra-noob question title states. I'm sure there is a simple script, but I can't find it. How can I make my gameobject cube disappear when I click it?

Attach a simple collider and this script to the object. Choose one of the options.

function OnMouseDown () {
  gameObject.active = false;
  //Destroy(gameObject);
  //renderer.enabled = false;
}

Check out this link about raycasting. This will make your object clickable:

http://unity3d.com/support/documentation/ScriptReference/Collider.Raycast.html

You'll then want to enable or disable the renderer if the raycast hits something

Here's the link for that:

Maybe something like this?:

var objToDel : GameObject; <--- But "cube" here
function Update()
{
var ray : Ray = Camera.main.ScreenPointToRay (Input.mousePosition);
var hit : RaycastHit;
if (collider.Raycast (ray, hit, 100.0)) 
{
delta = hit.gameObject.name;
}

if (delta == objToDel.gameObject.name)
{
 objToDel.active = false;
}
}

Not quite sure, can't verify, not @ my computer.
