What to put in native layer?

[amerkoleci]

Hi,
In my game engine I have similar layer as Foster platform, it has SDL3, stb image/truetype, rhi backends supporting vulkan/d3d12, mini audio

It uses C++ for rhi backends (specially d3d12) .

I do plan to wrap Jolt Physics and Box2D.
Question is, what would make sense to put in C++ and what in C#? High level renderer? Asset pipeline?

Thanks for suggestions!

I think the exact line is going to be subjective, but I try to just separate it with whatever ends up being easier in each language. A lot of the time stuff is much simpler in C#, so I'll put it there. But certain things like image loading, font loading, rendering, etc, is just simpler in C so it goes there. But the exact line is kind of arbitrary...

Honestly for high level rendering & asset pipelines, I would do that all in C#. I think it's performant enough (for anything I would ever make, anyway) and it will be so much easier to architect.

Thanks for sharing your ideas, the question wasn't related to Foster and thanks for taking time to share your opinion. I find it difficult to decide which is the middle line, what need to stay where (C++ or C#) but probably I should care less and keep things going :)
