How to Read Raw Asset using Play Asset Delivery at Runtime? about play-unity-plugins HOT 9 CLOSED

The runtime documentation is available here. Here's the part about reading those files from disk.

To load a raw asset you should:
"Use PlayAssetPackRequest.GetAssetLocation() to get an AssetLocation object. This provides the path, offset, and size of the asset so that it can be loaded from disk."

Here's an example using a file stream to load the text into a string:

FileStream assetFileStream = File.OpenRead(assetLocation.Path);
byte[] buffer = new byte[assetLocation.Size];
assetFileStream.Seek((long) assetLocation.Offset, SeekOrigin.Begin);
assetFileStream.Read(buffer, /* offset= */ 0, buffer.Length);
string fileContents = Encoding.UTF8.GetString(buffer, 0, buffer.Length);

Are you doing something similar?

Thanks for raising this issue. Currently the runtime API lags behind the packaging API a bit. We are working on updating the runtime API with a method that allows you to access the raw assets inside of those packs, but that functionality isn't supported yet.

In the meantime as a workaround/hack, you can use Unity's TextAsset to have GameObjects reference arbitrary files. Then you can package those GameObjects in AssetBundles and access the files using TextAsset.bytes.

Thank you for clarifying. I am currently not there yet with my project where lacking this feature would be an issue so I can wait for now.

Update: We added experimental support for this in the v1.1.1 release. If you want to give it a try, you can enable the PLAY_ASSET_DELIVERY_EXPERIMENTAL preprocessor definition in player settings (see the "Platform custom #defines" section here for how to do that)

@jamcohen May I know how to get Raw Asset now?

from play-unity-plugins.

@jamcohen Thanks for your help. We get the AssetLocation object but find that we can't load that file out. It would be good if you could show us some light.

This is the { path / size / offset } of the AssetLocation object { /data/app/com.DefaultCompany.TestAB-KRpgbnLxvKt8DzJ3vu3IKg==/split_assets.apk / 620847 / 2188 }. This should be a simple .txt file but we find that we could not read this file out with Readerstream using the path above.
