ここプーリングクラスは

using UnityEngine; 
using System.Collections.Generic; 

// A very simple object pooling class 
public class SimpleObjectPool : MonoBehaviour 
{ 
// the prefab that this object pool returns instances of 
public GameObject prefab; 
// collection of currently inactive instances of the prefab 
private Stack<GameObject> inactiveInstances = new Stack<GameObject>(); 

// Returns an instance of the prefab 
public GameObject GetObject() 
{ 
    GameObject spawnedGameObject; 

    // if there is an inactive instance of the prefab ready to return, return that 
    if (inactiveInstances.Count > 0) 
    { 
     // remove the instance from teh collection of inactive instances 
     spawnedGameObject = inactiveInstances.Pop(); 
    } 
    // otherwise, create a new instance 
    else 
    { 
     spawnedGameObject = (GameObject)GameObject.Instantiate(prefab); 

     // add the PooledObject component to the prefab so we know it came from this pool 
     PooledObject pooledObject = spawnedGameObject.AddComponent<PooledObject>(); 
     pooledObject.pool = this; 
    } 

    // put the instance in the root of the scene and enable it 
    spawnedGameObject.transform.SetParent(null); 
    spawnedGameObject.SetActive(true); 

    // return a reference to the instance 
    return spawnedGameObject; 
} 

// Return an instance of the prefab to the pool 
public void ReturnObject(GameObject toReturn) 
{ 
    PooledObject pooledObject = toReturn.GetComponent<PooledObject>(); 

    // if the instance came from this pool, return it to the pool 
    if(pooledObject != null && pooledObject.pool == this) 
    { 
     // make the instance a child of this and disable it 
     toReturn.transform.SetParent(transform); 
     toReturn.SetActive(false); 

     // add the instance to the collection of inactive instances 
     inactiveInstances.Push(toReturn); 
    } 
    // otherwise, just destroy it 
    else 
    { 
     Debug.LogWarning(toReturn.name + " was returned to a pool it wasn't spawned from! Destroying.");

だそれはC＃あなた

private List<int> _questions = null; 
private int _current = 0; 
void Start() 
{ 
    _questions = Enumerable.Range(0, questionPool.Length).ToList(); 
    Shuffle(_questions); 
} 
void Shuffle(List<int> list) 
{ 
    // put fisher-yates algorithm here to shuffle the numbers 
} 
void ShowQuestion() 
{ 
    var idx = _questions[_current++]; 
    var questionData = questionPool[idx]; 
}
