Question: Usage in Game Engine

[amerkoleci]

Hey,
It's not an issue but actually I have no other ways to reach you.

I would like to integrate into my game engine:

https://github.com/amerkoleci/alimer

I had issues with builtin Json serializer as I have custom components that could be registered from different assemblies, would also like to use it for entity component system registration, or even using own attributes like [Range(0, 10)] on properties, etc.

Do you have any suggestions for me? Or something Is should be aware ahead?

Thanks in advance,
Amer

No worries, I've converted this to a discussion.

Regarding your actual question, what you're trying to achieve should be possible in principle. All the shape abstractions include an AttributeProvider property that can be used to resolve custom attributes to be used by your converter types.

Thanks for quick answer, do you have any examples? Just because I don't want to work in the wrong direction

Thanks again

You can take a look at how the attribute validator works under the PolyType.Examples folder. For a more production-grade reference I would suggest looking at how the Nerdbank.MessagePack library is doing attribute resolution.

Thanks!

Hey,
Can I ask you how can I generate shapes for all types derived from a class? I cannot use DerivedTypeShape as components can be registered from different assemblies.

The idea is to use PolyType for serialization but as well for properties editing when running in the editor

Thanks in advance
Amer

Not supported unfortunately. The source generator needs to be able to reference the derived types at compile time so that the relevant shapes are derived. This is the same as how System.Text.Json works.
