自己比着视频敲的 代码如下：
using System.Collections;
using System.Collections.Generic;using UnityEngine;
using System.IO;
using UnityEngine.Networking;
public class LoadFromFileExample : MonoBehaviour {
IEnumerator Start () {
//AssetBundle ab = AssetBundle.LoadFromFile("AssetBundles/cubewall.unity3d");
//AssetBundle ab2 = AssetBundle.LoadFromFile("AssetBundles/share.unity3d");
//GameObject ob = ab.LoadAsset<GameObject>("cubewall");
//Instantiate(ob);
//第一种加载资源AB的方式、LoadFromMemoryAsyncy异步方式 先引入命名空间 using System.IO;
// AssetBundleCreateRequest request = AssetBundle.LoadFromMemoryAsync(File.ReadAllBytes("AssetBundles/cubeWall.unity3d"));
//yield return request;
//AssetBundle ab = request.assetBundle;
//第一种 加载的方式 不用异步加载
//AssetBundle ab= AssetBundle.LoadFromMemory(File.ReadAllBytes("AssetBundles/cubeWall.unity3d"));
//第二种加载AB的方式 LoadFromFile
//AssetBundleCreateRequest request= AssetBundle.LoadFromFileAsync("AssetBundles/cubeWall.unity3d");
// yield return request;
// AssetBundle ab = request.assetBundle;
//AssetBundle ab= AssetBundle.LoadFromFile("AssetBundles/cubeWall.unity3d");
//第三种加载AB的方式 WWW LoadFromCacheOrDownload
while (Caching.ready == false)
{
yield return null;
}
// WWW ww = WWW.LoadFromCacheOrDownload(@"file:///E:\U3DObject\AssetBundleProject\AssetBundles\cubeWall.unity3d", 1);
//WWW ww = WWW.LoadFromCacheOrDownload(@"http://localhost/AssetBundles/cubeWall.unity3d", 1);
//yield return ww;
//if (string.IsNullOrEmpty( ww.error)==false)
//{
// Debug.Log(ww.error); yield break;
//}
//AssetBundle ab= ww.assetBundle;
//第四种方法 使用unityWebRequest 先引入命名空间 using UnityEngine.Networking;
// string url = @"file:///E:\U3DObject\AssetBundleProject\AssetBundles\cubeWall.unity3d";
string url = @"http://localhost/AssetBundles/cubeWall.unity3d";
UnityWebRequest request = UnityWebRequest.GetAssetBundle(url);
yield return request.Send();
// AssetBundle ab= DownloadHandlerAssetBundle.GetContent(request); //第一种方法 或者，一下方法
AssetBundle ab = (request.downloadHandler as DownloadHandlerAssetBundle).assetBundle;
//使用里面的资源
GameObject ob = ab.LoadAsset<GameObject>("cubewall");
Instantiate(ob);
得到 依赖包
AssetBundle minfestAB= AssetBundle.LoadFromFile("AssetBundles/AssetBundles");
AssetBundleManifest minfest = minfestAB.LoadAsset<AssetBundleManifest>("AssetBundleManifest");
//foreach (var name in minfest.GetAllAssetBundles())
//{
// print(name);
//}
string[] strs = minfest.GetAllDependencies("CubeWall.unity3d");
foreach (var item in strs)
{
print(item);
AssetBundle.LoadFromFile("AssetBundles/" + item);
}
// 卸载
ab.Unload(true);
}
// Update is called once per frame
void Update () {
}
}
