[System.Serializable]
public class ObjectPoolItem
{
public GameObject objectToPool;
public int amountToPool;
public bool shouldExpand;
}

public class ObjectPooler : MonoBehaviour {

public static ObjectPooler SharedInstance;
public List<GameObject> pooledObjects;
public List<ObjectPoolItem> itemsToPool;

void Awake()
{
    SharedInstance = this;
}

void Start()
{
    pooledObjects = new List<GameObject>();
    foreach (ObjectPoolItem item in itemsToPool)
    {
        for (int i = 0; i < item.amountToPool; i++)
        {
            GameObject obj = (GameObject)Instantiate(item.objectToPool);
            obj.SetActive(false);
            pooledObjects.Add(obj);
        }
    }
}

public GameObject GetPooledObject(string tag)
{
    for (int i = 0; i < pooledObjects.Count; i++)
    {
        if (!pooledObjects_.activeInHierarchy && pooledObjects*.tag == tag)*_

{
return pooledObjects*;*
}
}
foreach (ObjectPoolItem item in itemsToPool)
{
if (item.objectToPool.tag == tag)
{
if (item.shouldExpand)
{
GameObject obj = (GameObject)Instantiate(item.objectToPool);
obj.SetActive(false);
pooledObjects.Add(obj);
return obj;
}
}
}
return null;
}
// Update is called once per frame
void Update () {

* }*
}
_*

SharedInstance.itemsToPoll[index].amountToPool = number;
