前言

本文章只有打包完的使用方法 ，需要打包的方法查看我的上一篇博客

加载方法

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using System.IO;
using UnityEngine.Networking;

public class LoadFromFileExample : MonoBehaviour {

    private string path;
    void Start()
    {
        path = "AssetBundles/kaka.luete";
        //从内存中异步加载
        StartCoroutine(LoadFromMemoryAsync());
        //内存中同步加载
        LoadFromMemory();
        //本地中异步加载
        StartCoroutine(LoadFromFileAsync());
        //从缓存或服务器上加载
		StartCoroutine(LoadFromCache());
		//第四种方法，最常用的方法，使用UnityWebRequest加载
		StartCoroutine(LoadFromUnityWebRequest());

    }
    /// <summary>
    /// 第一种加载AB的方式，从内存中异步加载
    /// </summary>
	IEnumerator LoadFromMemoryAsync()
    {
        AssetBundleCreateRequest requst = AssetBundle.LoadFromMemoryAsync(File.ReadAllBytes(path));
        yield return requst;
        AssetBundle ab = requst.assetBundle;
        GameObject wallPrefab = ab.LoadAsset<GameObject>("wall");
        Object[] objs = ab.LoadAllAssets();
        foreach (Object o in objs)

讲解

上边呢是使用了四种方法加载，本次使用本地加载方法（最后一种）

首先记得修改路径为你的本地路径

然后呢修改你的名字 ，就是你的AB包的名字

完事
