代码实现
PoolManager.cs
using System;
using System.Collections.Generic;

}
BaseFactory.cs
namespace Factory
{public abstract class BaseFactory{protected string obj_path;public BaseFactory(string obj_path_in){obj_path obj_path_in;}public abstract object CreateObject();public abstract void ResetObject(object obj);public abstract void RecycleObject(object obj);public abstract void DestroyObject(object obj);public abstract void ReleaseFactory();public virtual string GetObjPath(){return obj_path;}}
}使用
创建 Factory
using Factory;public class BulletFactory : BaseFactory
{public BulletFactory(string obj_path_in) : base(obj_path_in){}public override object CreateObject(){Bullet bullet new Bullet(obj_path);bullet.ReuseInit();return bullet;}public override void DestroyObject(object obj){((Bullet)obj).Destroy();}public override void RecycleObject(object obj){((Bullet)obj).Recycle();}public override void ReleaseFactory(){}public override void ResetObject(object obj){((Bullet)obj).ReuseInit();}
}
创建 object
using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class Bullet
{private GameObject go;private string path;private static GameObject prefab;public Bullet(string path_in){path path_in;if (prefab null){prefab (GameObject) Resources.Load(path);}}public void ReuseInit(){if (go){go.SetActive(true);}else{go GameObject.Instantiate(prefab);}go.GetComponentRecycleMe().DelayCall(1, Func);}public void Destroy(){GameObject.Destroy(go);}public void Recycle(){go.SetActive(false);}private void Func(){BulletManager.Ins.PushOne(path, this);}
}
创建 BulletManager
BulletManager.cs
using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using ToolManager;public class BulletManager : MonoBehaviour
{private PoolManager pool_mgr;private static BulletManager _ins;public static BulletManager Ins{get _ins;}private void Awake(){Init();}private void Init(){_ins this;pool_mgr new PoolManager();}public void PushOne(string path, Bullet obj){if (!pool_mgr.HasPool(path)){pool_mgr.AddPool(new BulletFactory(path));}pool_mgr.PushOne(path, obj);}public Bullet PopOne(string path){if (!pool_mgr.HasPool(path)){pool_mgr.AddPool(new BulletFactory(path));}Bullet bullet (Bullet)pool_mgr.PopOne(path);return bullet;}
}
验证
为了验证我写了一个 ShootManager.cs
using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class ShootManager : MonoBehaviour
{private ListBullet bullet_list;private string path Bullet;private static ShootManager _ins;public static ShootManager Ins{get _ins;}private void Awake(){Init();}private void Init(){_ins this;bullet_list new ListBullet();}private void Update(){if (Input.GetMouseButtonDown(0)){bullet_list.Add(BulletManager.Ins.PopOne(path));}}
}
创建之后过 1s 之后回收自己。 RecycleMe.cs
using System;
using System.Collections;
using System.Collections.Generic;
using UnityEngine;public class RecycleMe : MonoBehaviour
{public void DelayCall(float delay, Action func){StartCoroutine(DestroyAfterDelayCoroutine(delay, func));}IEnumerator DestroyAfterDelayCoroutine(float delay, Action func){yield return new WaitForSeconds(delay);func.Invoke();}}
效果 LRUPool
