Array Prefabs

• first you need declare array like this:

public List<GameObject> PrefabsArray;

• second, some method to instantiate prefabs and then delete it. wait a little and instantiate again, like this:

IEnumerator RandomInstantiator()
{
    while(true)
    {
        GameObject instance = Instantiate(PrefabsArray[UnityEngine.Random.Range(0, PrefabsArray.Count)]) as GameObject;
        yield return new WaitForSeconds(5f);
        Destroy(instance);
        yield return new WaitForSeconds(1f);
    }
}

• third, you need to start this 'instantiator' like this

void Start()
{
    StartCoroutine(RandomInstantiator());
}

• fourth, just attach script to any gameobject in scene, attach prefabs and you got it 8)

note: C#

finally

/* CODE C# */

using UnityEngine; using System.Collections; using System.Collections.Generic;

public class PowerUps : MonoBehaviour { public List powers; private float time = 5f; // in seconds

 void Start()
 {
     StartCoroutine(RandomInstantiator());
 }

 IEnumerator RandomInstantiator()
 {
     while (true)
     {
         float addXPos = Random.Range(-4, 4);
         Vector3 spawnPos = transform.position + new Vector3(addXPos, 3, 0);
         Instantiate(powers[randomPowerUps()], spawnPos, Quaternion.identity);
         yield return new WaitForSeconds(time);
     }
 }

 int randomPowerUps()
 {
     return UnityEngine.Random.Range(0, powers.Count);
 }

}

Thanks Scroodge =) although it had settled, I leave how to fix it .

/ CODE C# /

using UnityEngine; using System.Collections;

public class PowerUps: MonoBehaviour {

 private ArrayList powers;
 private float time = 300;
 private float count;
 public GameObject prefSmoke;
 public GameObject prefBomba;
 public GameObject prefCondor;
 public GameObject prefGas;
 public GameObject prefIce;
 public GameObject prefOtherBall;
 public GameObject prefOvni;
 public GameObject prefPiranha;
 public GameObject prefSmokeBlack;
 private GameObject randomPowerUp;

 void Start()
 {
     powers = new ArrayList();
     powers.Add(prefSmoke);
     powers.Add(prefBomba);
     powers.Add(prefCondor);
     powers.Add(prefGas);
     powers.Add(prefIce);
     powers.Add(prefOvni);
     powers.Add(prefPiranha);
     powers.Add(prefSmokeBlack);
 }
 void Update()
 {

     count++;
     if (count == time)
     {
         float addXPos = Random.Range(-4, 4);
         Vector3 spawnPos = transform.position + new Vector3(addXPos, 3, 0);
         Instantiate(powers[randomPowerUps()] as GameObject, spawnPos, Quaternion.identity);
         count = 0;
     }
 }

 int randomPowerUps()
 {
     int rand = Random.Range(0, powers.Count - 1);
     return rand;
 }

}
