首先明确对象池中的一些元素：1，预设 2，集合 3，名字标识 4构造

using System;
    using System.Collections.Generic;
    using UnityEngine;
    using System.Text;
    
    public class SubPool
    {
        //预设
        GameObject m_perfab;
    
        //集合
        List<GameObject> m_objects = new List<GameObject>();
    
        //名字标识
        public String Name
        {
            get
            {
                return m_perfab.name;
            }
        }
    
        //构造
        public SubPool(GameObject perfab)
        {
            this.m_perfab = perfab;
        }
        //取对象
        public GameObject OnSpwan()
        {
            GameObject go = null;
    
            foreach(GameObject item in m_objects)
            {
                if(!item.activeSelf)
                {
                    go = item;
                    break;
                }
               
            }
    
            if(go==null)
            {
                go = GameObject.Instantiate<GameObject>(m_perfab);
                m_objects.Add(go);  
            }
    
            go.SetActive(true);
            go.SendMessage("OnSpwan", SendMessageOptions.DontRequireReceiver);
    
            return go;
    
    
        }
    
        //回收对象
        public void OnUnSpwan(GameObject go)
        {
            if(Contains(go))
            {
                go.SendMessage("OnUnSpawn", SendMessageOptions.DontRequireReceiver);
                go.SetActive(false);
            }
        }
    
    
        //回收该对象池所有对象
        public void SwpanAll()
        {
            foreach(GameObject item in m_objects)
            {
                if(item.activeSelf)
                {
                    OnUnSpwan(item);
                }
            }
        }
    
        //是否包含在对象池中
        public bool Contains(GameObject go)
        {
            return m_objects.Contains(go);
        }
    }
