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";
    // AssetBundle ab = AssetBundle.LoadFromFile("AssetBundles/tt/wall.unity3d");
    // // GameObject wallPrefab=   ab.LoadAsset<GameObject>("wall");
    // //Instantiate(wallPrefab);
    //Object[] objs= ab.LoadAllAssets();
    // foreach (Object o in objs)
    // {
    //     Instantiate(o);
    // }
    //StartCoroutine(LoadFromMemoryAsync());
    // LoadFromMemory();
    //  StartCoroutine(LoadFromCache());
    StartCoroutine(LoadFromUnityWebRequest());
}

    GameObject wallPrefab = ab.LoadAsset<GameObject>("wall");
    Object[] objs = ab.LoadAllAssets();
    foreach (Object o in objs)
    {

    GameObject wallPrefab = ab.LoadAsset<GameObject>("wall");
    Object[] objs = ab.LoadAllAssets();
    foreach (Object o in objs)
    {

    foreach (Object o in objs)

    }
}

IEnumerator LoadFromCache()
{
    while (!Caching.ready)
    {
        //暂停一帧继续循环判断caching什么时候ready
        yield return null;
    }
    //从本地
    //WWW www= WWW.LoadFromCacheOrDownload(@"file://D:\UnityStudy\MyAB\AssetBundles\tt\wall.unity3d", 1);
    //从服务器
    WWW www = WWW.LoadFromCacheOrDownload(@"http://localhost/AssetBundles/wall.unity3d", 1);
    //等待下载完成
    yield return www;
    if (string.IsNullOrEmpty(www.error) == false)
    {
        Debug.Log(www.error);
        yield break;
    }
    AssetBundle ab = www.assetBundle;
    GameObject wallPrefab = ab.LoadAsset<GameObject>("wall");

        Instantiate(o);
    }

IEnumerator LoadFromUnityWebRequest()
{//从本地
  string uri = @"file:///D:\Unity2017的工程\AB打包试验\AssetBundles\kaka.luete";
 //从服务器
   // string uri = @"http://localhost/AssetBundles/wall.unity3d";
    UnityWebRequest request = UnityWebRequest.GetAssetBundle(uri);
    //使用Send方法进行下载
    yield return request.Send();
    //  AssetBundle ab = DownloadHandlerAssetBundle.GetContent(request);
    AssetBundle ab = (request.downloadHandler as DownloadHandlerAssetBundle).assetBundle;
    GameObject wallPrefab = ab.LoadAsset<GameObject>("kaka");
    Object[] objs = ab.LoadAllAssets();
    foreach (Object o in objs)
    {
        Instantiate(o);
    }
}

}

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
