Question

我试图在运行时从android本地存储中的下载assetbundle加载一个对象，但是没有找到结果。虽然资产捆绑存在于我的Android设备的本地存储中。

请有人帮我这样做，以下是我写的代码：

public GameObject obj;

IEnumerable LoadObject()
{
    AssetBundle bundle = AssetBundle.CreateFromFile(Application.persistentDataPath + "/androidassetbundle4");
    yield return bundle;

    AssetBundleRequest request = bundle.LoadAssetAsync("boat", typeof(GameObject));
    yield return request;

    obj = request.asset as GameObject;
    obj.transform.position = new Vector3(0.08f, -2.345f, 297.54f);
    obj.transform.Rotate(350.41f,400f,20f);
    obj.transform.localScale = new Vector3(1.0518f, 0.998f, 1.1793f);

    Instantiate(obj);

    bundle.Unload(false);

}//end of Method LoadObject

CreateFromFile已弃用。 LoadFromFile和LoadFromFileAsync是要使用的新功能。不确定这是不是问题，但下面的代码应该这样做。

IEnumerator LoadObject()
{
    AssetBundleCreateRequest bundle = AssetBundle.LoadFromFileAsync(System.IO.Path.Combine(Application.streamingAssetsPath, "assetbundlename"));
    yield return bundle;

    AssetBundle myLoadedAssetBundle = bundle.assetBundle;
    if (myLoadedAssetBundle == null)
    {
        Debug.Log("Failed to load AssetBundle!");
        yield break;
    }

    AssetBundleRequest request = myLoadedAssetBundle.LoadAssetAsync<GameObject>("boat");
    yield return request;

    obj = request.asset as GameObject;
    obj.transform.position = new Vector3(0.08f, -2.345f, 297.54f);
    obj.transform.Rotate(350.41f, 400f, 20f);
    obj.transform.localScale = new Vector3(1.0518f, 0.998f, 1.1793f);

    Instantiate(obj);

    myLoadedAssetBundle.Unload(false);
}

您无法通过Android中的CreateFromFile或LoadFromFile访问本地存储中的文件，而是使用LoadFromCacheOrDownload，而在android中，这是您的StreamingAssets的地址："jar:file://" + Application.dataPath + "!/assets/" 正如统一文档中提到的那样：StreamingAssets

使用unity，没有从android中的本地存储加载下载的资产
