Help: script that worked don't work with Unity 3.5

Hello everyone,

I need help with a spawnscript I made that worked earlie,r but with the recent updates on Unity, it does not seems to work.

Here's the script:

using UnityEngine; using System.Collections;

public class SpawnScript : MonoBehaviour { public int AmountEnemyInWave; public float SpawnCountdown = 1.0f; public GameObject[] spawnPoints; public GameObject[] enemy;

 private float SpawnTimer;
 private int CurrentEnemyNumber = 0;
 private bool hasFinished = false;
 
 void Start()
 {
     SpawnTimer = 0.0f;
 }
 
 void SpawnEnemy()
 {    
     if(!hasFinished)
     {    
         SpawnTimer += Time.deltaTime;
         
         // Debug.Log("SpawnTimer value " + SpawnTimer);
         // Debug.Log("SpawnCountdown value " + SpawnCountdown);
         // Debug.Log("SpawnTimer value >= SpawnCountdown value : " + (SpawnTimer >= SpawnCountdown));
             
         if(SpawnTimer >= SpawnCountdown)
         {
             // Debug.Log ("Hi darling");
             
             Debug.Log(enemy[0]);
             Debug.Log(spawnPoints[0]);
             
             Instantiate(enemy[0], (spawnPoints[0].transform.position), (spawnPoints[0].transform.rotation));
             CurrentEnemyNumber += 1;
             SpawnTimer = 0.0f;
         }
     }
 }
 
 void Update() 
 {
     SpawnEnemy();
     
     if(CurrentEnemyNumber >= AmountEnemyInWave)
     {
         // Debug.Log("CurrentEnemyNumber >= AmountEnemyInWave : " + (CurrentEnemyNumber >= AmountEnemyInWave));
         
         hasFinished = true;
     }
 }

}

Notice that all the Debug.Log are in comments, but I can attest that they work. I've seen them all print their message at the console screen.

In the enemy array, I put a prefab of my enemy. It's important to take this into account because the main problem is that Unity seems to detect the spawn thing (since the debug.log // Debug.Log("CurrentEnemyNumber >= AmountEnemyInWave : " + (CurrentEnemyNumber >= AmountEnemyInWave)); does show in console) But no physical enemy appears.

Any clues, someone? This is a major issue for me. Thanks a lot!
