Hi all,
I am looking for some urgent advice/help regarding asset bundle LoadFromCacheOrDownload.
UnloadAssetBundle is called on a button click in the UI.
loadedAssetBundle is a member variable of class that has the functions.
The following are the steps I take :
1. LoadFromCacheOrDownload(URL, 0) <- Get a WWW download with assetbundle from the web.
2. The above is successfull the first time. I check the IsVersionCached -> Returns TRUE.
3. Call Unload(false) on the asset bundle then destroy the object.
4. Try LoadFromCacheOrDownload(URL, 0) again with the same asset bundle.
5. Get the error -> Cannot load cached AssetBundle. A file of the same name is already loaded from another AssetBundle.
See code below :
private AssetBundle loadedAssetBundle;
public IEnumerator DownloadAtURL(string assetName, string URL)
{
Debug.Log("PRE ASSET CACHED = " + Caching.IsVersionCached(assetName, 0));
Debug.Log("Downloading using -> WWW.LoadFromCacheOrDownLoad");
var www = WWW.LoadFromCacheOrDownload(URL, 0);
yield return www;
if(!string.IsNullOrEmpty(www.error))
{
Debug.Log(www.error);
yield return null;
}
Debug.Log("Finished downloading assetbundle");
Debug.Log("POST ASSET CACHED = " + Caching.IsVersionCached(assetName, 0));
loadedAssetBundle = www.assetBundle;
}
public void LoadAssetBundle()
{
Debug.Log("Loading all assets for bundle " + loadedAssetBundle.name);
loadedAssetBundle.LoadAllAssets();
}
public void UnloadAssetBundle()
{
Debug.Log("Unloading asset bundle " + loadedAssetBundle.name);
loadedAssetBundle.Unload(true);
Destroy(loadedAssetBundle);
}
See output below :

Any ideas why UNLOAD is not working ?! Seems like a bug in unity, not sure what else I can do here.
Would be most appreciated and thanks in advance.
