Unity 2D respawning Instantiate issue

Question

I am making a 2D Space-invaders style game and am having GREAT difficulty with respawning. What i want to happen is when the SpaceShip is hit, it gets Destroyed, e.x. Destroy();

But when i try to Instantiate() the Prefab of the SpaceShip it does the (clone)(clone) problem, so I am trying to Make an Empty GameObject run script that spawns in a Prefab of the SpaceShip, AND when it gets Destroy(); it respawns after 3 seconds. Much help appreciated, and i'm coding in JavaScript.

(clone)(clone) problem? What gameobject are you passing to Instantiate? It sounds like you're instantiating by reference to the gameobject in the scene rather than from your assets folder. — Agumander
I'm trying to Instantiate a prefab from my assets, and the clone problem is not an issue anymore i'm just trying to Instantiate my SpaceShip Prefab from a Empty GameObject's script when the game starts, and when the SpaceShip Prefab gets Destroy(); — Hudson

Have one class that instantiates every couple of seconds from a prefab. You will need to drag via the Editor the playerPrefab and you will need to specify the location for the spawn.

public class Spawner : Monobehaviour
{
    public GameObject playerPrefab;

    public void spawn()
    {
        Instantiate(playerPrefab, spawnPosition, spawnRotation);
    }
}

Then when your Player dies you can a SendMessage to the Spawner class.

public class Player : MonoBehaviour
{
    void Update()
    {
        if(hp <= 0)
        {
             // Grab the reference to the Spawner class.
             GameObject spawner = GameObject.Find("Spawner");

             // Send a Message to the Spawner class which calls the spawn() function.
             spawner.SendMessage("spawn");
             Destroy(gameObject);
        }
    }
}

Same code in UnityScript

Spawner.js

  var playerPrefab : GameObject;

  function spawn()
  {
      Instantiate(playerPrefab, spawnPosition, spawnRotation);
  }

Player.js

  function Update()
  {
      if(hp <= 0)
      {
          // Grab the reference to the Spawner class.
          var spawner : GameObject = GameObject.Find("Spawner");

          // Send a Message to the Spawner class which calls the spawn() function.
          spawner.SendMessage("spawn");
          Destroy(gameObject);
      }
  }
