unity 写一个协程对象池管理的脚本

好，以下是一个简单的协程对象池管理的脚本，使用C#编写：

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

public class CoroutineObjectPool : MonoBehaviour
{
    public GameObject prefab;
    public int poolSize = 10;

    private List<GameObject> objectPool = new List<GameObject>();

    private void Start()
    {
        for (int i = 0; i < poolSize; i++)
        {
            GameObject newObj = Instantiate(prefab, transform);
            newObj.SetActive(false);
            objectPool.Add(newObj);
        }
    }

    public IEnumerator SpawnObjectFromPool(Vector3 position, Quaternion rotation, float delay)
    {
        GameObject obj = GetObjectFromPool();
        obj.transform.position = position;
        obj.transform.rotation = rotation;
        obj.SetActive(true);
        yield return new WaitForSeconds(delay);
        obj.SetActive(false);
    }

    private GameObject GetObjectFromPool()
    {
        for (int i = 0; i < objectPool.Count; i++)
        {
            if (!objectPool[i].activeInHierarchy)
            {
                return objectPool[i];
            }
        }
        GameObject newObj = Instantiate(prefab, transform);
        newObj.SetActive(false);
        objectPool.Add(newObj);
        return newObj;
    }
}

使用方法：

1. 将该脚本挂载到一个GameObject上；
2. 在Inspector面板中设置要管理的对象的预制体（prefab）和对象池大小（poolSize）；
3. 在代码中调用SpawnObjectFromPool方法即可从对象池中获取对象并激活，经过指定的延迟后再将其隐藏回收。

示例代码：

public class SpawnObject : MonoBehaviour
{
    public CoroutineObjectPool poolManager;
    public float delay = 2f;

    private void Start()
    {
        StartCoroutine(Spawn());
    }

    private IEnumerator Spawn()
    {
        while (true)
        {
            yield return new WaitForSeconds(delay);
            Vector3 position = transform.position;
            Quaternion rotation = transform.rotation;
            StartCoroutine(poolManager.SpawnObjectFromPool(position, rotation, delay));
        }
    }
}

在上述示例代码中，每隔指定的时间间隔，从SpawnObject的位置和旋转角度获取一个对象，并经过指定的延迟时间后将其回收。
