《搬砖日记》AssetsBundle实现资源更新及通过反射添加脚本

using UnityEditor;
using System.IO;

public class CreatAssetsBundle
{
    [MenuItem("AssetsBundle/Build AssetBundles")]
    static void BuildAllAssetBundles()//进行打包
    {
        string dir = "AssetBundles";
        //判断该目录是否存在
        if (Directory.Exists(dir) == false)
        {
            Directory.CreateDirectory(dir);//在工程下创建AssetBundles目录
        }
        //参数一为打包到哪个路径，参数二压缩选项  参数三 平台的目标
        BuildPipeline.BuildAssetBundles(dir, BuildAssetBundleOptions.None, BuildTarget.StandaloneWindows64);
    }
}

using UnityEngine;
using System.Collections;
using UnityEngine.Networking;
using System.Reflection;
using System;
using System.IO;
using System.Net;

public class LoadAssetbundles : MonoBehaviour
{
    IEnumerator Start()
    {
        //本地服务器assetbundle文件存放路径
        string path = "http://localhost/AssetBundle/cubeab.ab";
        //通过WWW加载assetbundle文件，1代表版本号
        WWW www = WWW.LoadFromCacheOrDownload(path, 1);
        yield return www;
        //取得www中的assetBundle
        AssetBundle ab = www.assetBundle;
        //将.bytes文件转化为TextAsset
        TextAsset text = ab.LoadAsset("ABTest.bytes", typeof(TextAsset)) as TextAsset;
        //转化为byte数组
        byte[] by = text.bytes;
        //通过反射获取CubeTest类
        Assembly am = Assembly.Load(by);
        Type type = am.GetType("CubeTest");
        //将assetBundle中的物体加载出来放入数组中
        GameObject[] obj = ab.LoadAllAssets<GameObject>();
        //在场景中生成assetBundle中的物体
        foreach (GameObject o in obj)
        {
            Instantiate(o);
        }
        //给生成的游戏物体添加 CubeTest脚本
        GameObject.Find("Cube(Clone)").AddComponent(type);
