Save AssetBundle after LoadFromFile has been called? Takes too long each time.

Hi,

I have an app that delivers Sessions of VR experiences to a user's iPhone. We distribute multiple worlds through on demand resources. Currently a user downloads the asset bundle through on demand resources and then Unity runs AssetBundle.LoadFromFile() to load the asset bundle and then it launches the scene. The assetbundles only contain scenes. This step takes a while compared to before when we shipped the app with the content already installed.

I am wondering if there is a way to save the asset bundle in a way that I won't have to call LoadFromFile() each time. Or is there a way to do that in a more efficient manner? The loading time is an issue and since the async operation .progress and .isDone don't work there's not even a way to show a loading bar (Let me know if you have a solution to that as well lol)

Thanks!

 

Thanks for the repsonse!

I am using on demand resources currently to distribute the assetbundles. Is there a way to cache the bundles after they are loaded the first time, similarly to how the UnityWebRequest method would do it?

Also do you know if there are plans to fix the .isDone and .progress fields for the AsyncOperations? Can't understand how I can give users loading feedback without them.

Thanks

 

Thank you for the response. That is good to know that you can load from local files. Will the cached memory be purged? How can I check whether the cache is still there or will it check automatically and recreate assetbundle if it's not? I tried something similar in the past but couldn't get it to load from odr resource paths. Is there a requirement for where the files can be stored?
