the cube should have a collider, and the script i thionk you want is when you click on the cube, it's destroyed forever. until you play the scene again.

here it is:

function OnMouseDown()
{
  Destroy(gameObject);
}

that should work.

right! also, this script goes on the object(s) you want to destory.

Hey! I think this URL can help you http://docs.unity3d.com/Documentation/ScriptReference/MonoBehaviour.OnMouseDown.html Hope i helped ;)

Rather than destroying the game object, just load a scene. For example:

Application.LoadLevel("Scene");

can you do the same but instead of destroying the game object it changes to another scene?

Tomeromero,

This script will destroy the gameobject when you click:

    function Update () {
   if(Input.GetMouseButton(0))
    Destroy (gameObject);}

And this script, will give you an idea of how to do what you asked... (I am not posting this whole script, so you can learn, and answer these questions yourself)

// Public member variables that you can change in the Inspector
public var distance : float = 5.0;

function Update()
{
    Debug.DrawRay(transform.position, transform.forward * distance, Color.white);
    // Shoot the ray on mouse click
    if (Input.GetButtonUp("Fire1"))
    {
        var hit : RaycastHit;

        // Cast a ray forward from our position for the specified distance
        if (Physics.Raycast(transform.position, transform.forward, hit, distance))
        {
            // Add a specified force to the Rigidbody component to the other GameObject
            Debug.Log("Destroyed " + hit.collider.gameObject.name);
            try
            {
                hit.collider.gameObject.Destroy;
            } catch (e) { }
        }
    }
}

-Hope I helped
