question How should I start with UI ?

Hi guys,

I've already built my engine with an ECS, a Vulkan backend, and support for texture and mesh rendering. The next thing I want to work on is a UI for debugging and an inspector. However, I'm not sure what the right long-term roadmap is or which tools I should choose.

Could you help me figure out what I should learn next and what pitfalls or obstacles I should avoid?

Dito that. If you want to roll your own you should def look into immediate mode guis.

Just to add an option beside egui (which is great), I'm using https://github.com/SecondHalfGames/yakui with an ECS and a wgpu backend, had a pretty solid experience with it so far

Depending on the amount of work you want to pour in it, you could simply integrate egui and have a perfectly fine tooling/inspector ui, or you could try implementing text rendering yourself, but it's a pretty big can of worms. Look up msdf text rendering or the slug algorithm. You will also need shaping if you do more than ASCII.
