Creating importers?

[asmaloney]

Is anyone aware of an example of a GDExtension which adds an importer for a new file format? (I mean one that works like OBJ or glTF.)

I can't find an explicit description what each of the ModuleInitializationLevels mean or what needs to be an EditorSceneFormatImporter vs. EditorImportPlugin vs. simply a Resource (or if those are even what I should be implementing?).

It's hard to use the built-in importers as examples because they are using the internal interface.

Any progress on some proper GDExtension docs somewhere? 😄

Once I have an EditorImportPlugin do I need to call something specific to "hook it up"? Or should simply registering it with ClassDB::register_class<> do it?

I have created one and the extension loads fine, but my format doesn't show up in the "Import As" list in the Import tab.

Adding importers is done via an EditorPlugin, but GDExtension is still missing a way to register editor plugins: #640

Thanks @Zylann.

The only things I want to do with GDExtension at the moment are file format importers, so that's a bummer!

If there's anything I can do to help with getting this capability in there, please let me know.
