Is it possible to create Stride assets programmatically outside GameStudio?

[HuangMiu]

Hi, I’ve created a custom frame animation asset in Stride. It can be created in GameStudio and loaded at runtime via Content.Load without any issues.

Now I’d like to build an external console tool to convert JSON exported from Aseprite into my custom asset format.

Is there a way to use Stride’s asset/content pipeline directly (e.g., serialization or content management APIs) to generate asset files from class data, instead of manually constructing the asset YAML/text files?

Any recommended approach for this kind of workflow would be greatly appreciated. Thanks!

The page you provided explains how to create custom assets, and I have already followed it to implement my own asset type.

However, my goal is to build an automated asset pipeline that converts data from external tools into Stride assets.

What I want to know is whether Stride provides a way to generate asset files directly from an external C# console application, instead of manually constructing the asset file as text.

For example, I can parse JSON exported from Aseprite and populate a corresponding C# class. Is there any API that allows me to serialize this data and save it as a *.sdsheet file (or other Stride asset format) that can be recognized by Stride?

Custom assets are not just some datatype, they also act like an importer, or a parser.

There is nothing special about 'asset files', they are just Yaml with a few additional serialization features. You can reference Stride's yaml serializer in an application and use it to produce them. I don't see why you would want to do that though, you could create your asset like shown in that document, and like Stride's models, textures and audio asset, have a path field on that asset that points to the JSON file the asset should handle. Then in DoCommandOverride you would open the Aseprite JSON file at that path, parse it and create / populate the c# class like you mentioned.

Thanks a lot for the detailed explanation, this really helped clarify things for me.
