加载AB包注意事项

1.基础的正确的加载方式
在这里插入图片描述
2.有问题的基础的加载方式

3.总结 :在加载AB包资源的时候必须先加载资源所依赖的资源不然可能会造成贴图或者其他成分丢失这个值得注意

Manifest基础解释

Dependencies ：当前资源所依赖的资源
Assets：当前资源的路径

在这里插入图片描述

从内存中加载AB包

  //2.从内存加载AB包

        string path2 = "C:/Users/Administrator/Desktop/WorkSpace5.6/AB_Packet/Assets/AssetBundles/cubewall";
        //异步返回的是一个请求Request
        AssetBundleCreateRequest request1 = AssetBundle.LoadFromMemoryAsync(File.ReadAllBytes(path1));
        AssetBundleCreateRequest request2 = AssetBundle.LoadFromMemoryAsync(File.ReadAllBytes(path2));
        yield return request2;

        //同步方式直接返回的是AssetBundle
        AssetBundle.LoadFromMemory(File.ReadAllBytes(path2));
        AssetBundle ab = request2.assetBundle;
        GameObject cube = (ab.LoadAsset("Cube")) as GameObject;
        Instantiate(cube);

从服务器加载AB包


        //3.从服务器种加载AB包的方式www
     IEnumerator Start()
    {
        //string path2 = "C:/Users/Administrator/Desktop/WorkSpace5.6/AB_Packet/Assets/AssetBundles/cubewall";
        string path2 = @"http://localhost/AssetBundles/cubewall";
        WWW www = WWW.LoadFromCacheOrDownload(path2, 1);
        while (Caching.ready == false)
        {
            yield return null;
        }
        yield return www;
        if (string.IsNullOrEmpty(www.error) == false)
        {
            Debug.Log(www.error);
            yield break;
        }
        AssetBundle ab = www.assetBundle;
        //使用
        GameObject Cube = ab.LoadAsset<GameObject>("Cube");
        Instantiate(Cube);
    }

通过WebRequest加载

    //第4种方式通过WebRequest

    IEnumerator Start()
    {


        string uri = @"http://localhost/AssetBundles/cubewall";
        UnityWebRequest request = UnityWebRequest.GetAssetBundle(uri);
        yield return request.Send();
        //AssetBundle ab = DownloadHandlerAssetBundle.GetContent(request);
        DownloadHandlerAssetBundle ab = request.downloadHandler as DownloadHandlerAssetBundle;
        GameObject Cube = ab.assetBundle.LoadAsset<GameObject>("Cube");
        Instantiate(Cube);

        //通过加载Mainifest文件来加载资源所依赖的包


        AssetBundle assetBundle = AssetBundle.LoadFromFile(@"C:\Users\Administrator\Desktop\WorkSpace5.6\AB_Packet\Assets\AssetBundles\AssetBundles");
        AssetBundleManifest abManifest = assetBundle.LoadAsset<AssetBundleManifest>("AssetBundleManifest");
        foreach (string name in abManifest.GetAllDependencies("cubewall"))
        {
            print(name);
            AssetBundle.LoadFromFile(@"C:\Users\Administrator\Desktop\WorkSpace5.6\AB_Packet\Assets\AssetBundles\" + name);
        }
