... is not registered in TypeRegistry, what does it mean?

I always found something is not registered in TypeRegistry on the egui, what does it mean?

When you have a custom type, the inspector needs to use the Reflect trait to show UI for it.

To do that you need to #[derive(Reflect)] and call app.register_type::<PlayerSpriteIndices>(). Maybe the message could explicitly call that out.

Hi, I am trying to do exactly this for a struct which has types from another library (nalgebra):

So I guess I need to implement type_path (and possibly more?) for nalgebra::Vector2, but I am a bit lost as to how, maybe someone here can give me hint 🤞
