Get Updated AssetsBundles > BuildPipeline.BuildAssetBundles

Unity Engine
1

Hi,

I’m not sure if I missing something, but I’m using the new AssetBundles creation in Unity 5 with BuildPipeline.BuildAssetBundles.

I’m wondering if it’s possible to have a list of the new created and/or updated AssetBundles files ?

I need to have this list to upload theme afterwards.

Is it possible ?

The situation as far as I can tell: The BuildAssetBundles() function returns an AssetBundleManifest, which itself has a function of GetAllAssetBundles() which returns an array of the names of the bundles that were just built, but what the OP wants appears to be a list of names of the ASSETS within those bundles, which requires another step (I’m guessing) that I also don’t know how to manage.

@LeftyRighty I think a 30 minute general-use video that may or may not answer the question may in fact be more aggravating than helpful- the real problem is that the documentation for this new system is really lacking, and the numerous video “tutorials” they’ve posted online make searching for specific aspects of their new systems incredibly frustrating.

@Ziboo if you make/use AssetBundleBuilds[ ] as a parameter in the call to BuildAssetBundles(), you can then use the list within the builds afterward (not the manifest, since it doesn’t seem to hold the data you want), but even then it won’t tell you which assets were updated since the last build (at least you’ll know for certain those assets within the build have been bundled, though).

didn’t say it would help, said it might be of interest… :face_with_spiral_eyes: not everyone knows unity puts out vids on stuff :stuck_out_tongue:

@LeftyRighty I know, my apologies- that wasn’t an attack on you, just my frustration at the videos’ existence. However, I’m of the belief that linking the “new features” videos perpetuates the myth that the videos are in fact helpful and should be shared, where in reality they need to be burned with fire so that the Unity staff has to go out of their way to make complete written documentation of their new features in the future. :slight_smile:

Thank you all for your answer.

So I didn’t miss anything, maybe Unity should implement this function, I think it’s pretty usefull.

For a quick fix, I ended up doing something like this

  //Keep Track Of Bundles
        var bundlesCreated = new Dictionary<string, DateTime>();
        foreach (
            string file in Directory.GetFiles(exportFolder, "*.unity3d", SearchOption.AllDirectories))
        {
            bundlesCreated.Add(file, File.GetLastWriteTime(file));
        }

        //Build
        AssetBundleManifest m = BuildPipeline.BuildAssetBundles(exportFolder, 0, bt);

        //Compare to get bundles builded
        foreach (
            string file in Directory.GetFiles(exportFolder, "*.unity3d", SearchOption.AllDirectories))
        {
            if (!bundlesCreated.ContainsKey(file))
            {
                Debug.Log("New Bundle:  " + file);
                bundlesCreated.Add(file, File.GetLastWriteTime(file));
            }
            else
            {
                Debug.Log("Old Bundle:  " + file + File.GetLastWriteTime(file));
                if (bundlesCreated[file].CompareTo(File.GetLastWriteTime(file)) != -1)
                {
                    bundlesCreated.Remove(file);
                }
            }
        }
