Spawning different prefabs randomly using Object pooling

Questions & Answers

I want to spawn 3 different types of prefab randomly through pool manager script. I found the given script when I access this script in cube Spawner script but Here It doesn’t take more than one prefabs
sorry for weak English .If any one get my point help thanks.
Dictionary> poolDictionary = new Dictionary>();
static PoolManager _instance;
public static PoolManager instance
{
get
{
if (_instance == null)
{
_instance = FindObjectOfType();
}
return _instance;
}
}

public void CreatePool(GameObject prefab,int poolSize)
{
    int poolKey = prefab.GetInstanceID();
    if (!poolDictionary.ContainsKey(poolKey))
    {
        poolDictionary.Add(poolKey,new List<GameObject>());
        for(int i = 0; i < poolSize; i++)
        {
            GameObject newObject = Instantiate(prefab);
            poolDictionary[poolKey].Add(newObject);
        }
    }
}
public GameObject GetObject(GameObject prefab)
{
    int poolKey = prefab.GetInstanceID();
    if (poolDictionary.ContainsKey(poolKey))
    {
        List<GameObject> pool = new List<GameObject>();
        for(int i = 0; i < pool.Count; i++)
        {
            if (!pool*.activeInHierarchy)*

{
return pool*;*
}
}
GameObject newObject = Instantiate(prefab);
poolDictionary[poolKey].Add(newObject);
return newObject;
}
return null;
}
Bellow is the script where I want to spawn different prefabs.
private void Awake()
{
currentPosition = cubePrefab.transform.position;
}
private void Start()
{
PoolManager.instance.CreatePool(cubePrefab, poolSize);
InvokeRepeating(“SpawnCubes”,0f, 10f);
}
private void SpawnCubes()
{

GameObject cubeObject = PoolManager.instance.GetObject(cubePrefab);
cubeObject.transform.position = currentPosition;
cubeObject.SetActive(true);
Vector3 newPosition = currentPosition;
newPosition.z += distance;
currentPosition = newPosition;

}

Use mine: GitHub - Ven0maus/UnityObjectPooler: A unity object pool that works with any unity component.

You can pool any object of type component, including monobehaviours like gameobject.
And you can retrieve custom components by ObjectPool.GetCustom(a => lamba criteria);
It is documented here: Documentation · Ven0maus/UnityObjectPooler Wiki · GitHub

And there is a small sample project included.
