Unity 加载AssetBundle的方法

1，从二进制文件中异步加载AB

IEnumerator LoadAB()
{
     
　　AssetBundleCreateRequest request = AssetBundle.LoadFromMemoryAsync(File.ReadAllBytes(path));
　　yield return request;
　　AssetBundle ab = request.assetBundle;
　　GameObject monster = ab.LoadAsset<GameObject>("Monster");
　　Instantiate(monster);
}

2，资源同步加载

Instantiate(AssetBundle.LoadFromMemory(File.ReadAllBytes(path)).LoadAsset<GameObject>("Monster"));

3，从文件中进行直接加载

AssetBundle ab = AssetBundle.LoadFromFile("AssetBundles/scene/monster.ab");
GameObject monster= ab.LoadAsset<GameObject>("Monster");
Instantiate(monster);

4，从文件中进行异步加载

IEnumerator LoadCacheOrDownloadFromFile(string path)
{
     
　　WWW www = WWW.LoadFromCacheOrDownload(path, 1);
　　yield return www;

　　if( !string.IsNullOrWhiteSpace(www.error) )
　　{
     
　　　　Debug.Log(www.error);
　　　　yield break;
　　}
　　AssetBundle ab = www.assetBundle;
　　GameObject monster = ab.LoadAsset<GameObject>("Monster");
　　Instantiate(monster);
}

5，网页加载 UnityWebRequest（一）

UnityWebRequest request = UnityWebRequestAssetBundle.GetAssetBundle(path);
yield return request.SendWebRequest();
AssetBundle ab = DownloadHandlerAssetBundle.GetContent(request);
GameObject monster = ab.LoadAsset<GameObject>("Monster");
Instantiate(monster);

6，网页加载 UnityWebRequest（二）

UnityWebRequest request = UnityWebRequest.Get(path);
request.downloadHandler = new DownloadHandlerAssetBundle (path, 0);
yield return request.SendWebRequest();
AssetBundle ab = DownloadHandlerAssetBundle.GetContent(request);
GameObject monster = ab.LoadAsset<GameObject>("Monster");
Instantiate(monster);

7，网页加载 UnityWebRequest（三）

UnityWebRequest request = UnityWebRequestAssetBundle.GetAssetBundle(path);
yield return request.SendWebRequest();
AssetBundle ab = (request.downloadHandler as DownloadHandlerAssetBundle).assetBundle;
GameObject monster = ab.LoadAsset<GameObject>("Monster");
Instantiate(monster);

8，读取Manifest文件，获取它们的依赖关系并且加载出来

AssetBundle manifestAB = AssetBundle.LoadFromFile("AssetBundles/AssetBundles");
AssetBundleManifest manifest = manifestAB.LoadAsset<AssetBundleManifest>("AssetBundleManifest");
string[] strArr = manifest.GetAllDependencies("scene/monster.ab");
foreach (var item in strArr)
{
     
　　AssetBundle.LoadFromFile("AssetBundles/" + item);
}
