Maybe there's something fundamental I've misunderstood about AssetBundles, but am I correct in assuming that AssetBundles is something that you should be able to change and update after release of your game, without having to change game code? If so, I don't understand the WWW class' LoadFromCacheOrDownload. This one takes a version number as input and only if this version number has changed or no cached version of the object exists does it download the package.
However this means that if we need to get a new version of an AssetBundle downloaded, we'd have to change the version number in LoadFromCacheOrDownload in our game code, which kind of defeats the purpose. What we want is to be able to change content of an AssetBundle to i.e. include new textures or new settings for objects, without having to create an update for our app, which the users would then have to download from the app store.
Basically the functionality we're after should download the AssetBundle if no cached version exists or the AssetBundle has changed on the server, independent on what version number is passed to LoadFromCacheOrDownload. How would I go about implementing such a feature? We don't want to re-download the entire package every time, since it could potentially be rather large.
