unity---资源加载模块&对象池的优化

资源加载模块

异步加载

委托和lambda表达式

协程

泛型

资源加载类

代码

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.Events;
public class ResMgr : Singleton<ResMgr>
{
    public T Load<T>(string name ) where T:Object{
        T res = Resources.Load<T>(name);
        if(res is GameObject){
            return GameObject.Instantiate(res);
        }
        return res;
    }
    public void LoadAsync<T>(string name , UnityAction<T> callBack)where T:Object{
        MonoMgr.Instance.StartCoroutine(ReallyLoadAsync(name,callBack));
    }
    private IEnumerator ReallyLoadAsync<T>(string name ,UnityAction<T>callBack)where T:Object{
        ResourceRequest r = Resources.LoadAsync<T>(name);
        yield return r;
        if(r.asset is GameObject)
            callBack(GameObject.Instantiate(r.asset)as T);
        else callBack(r.asset as T);
    }
