Questions regarding this project #50

Closed Raj2032 closed 2 years ago

Raj2032 commented 2 years ago

Hi I have some questions regarding this project:

  1. Can it easily be integrated into a game engine or not?
  2. Does it have any caching layouts which is similar to retained graphics?
  3. Does it work for Android, if not are there plans for support for Android?

Hello, thanks for filing an issue!

  1. Can it easily be integrated into a game engine or not?

Yes! Easy integration is a top priority. Currently, if the engine uses wgpu and winit, integration is very easy. Otherwise, you'll have to write an integration for your graphics API and windowing library.

If you need support for another windowing library like SDL2, I'd be willing to integrate it into this repository.

  1. Does it have any caching layouts which is similar to retained graphics?

Currently, the widget tree is retained between frames. Layout is calculated on every frame, and the entire UI is rerendered every frame. We'll eventually cache layouts and only recompute them when needed.

  1. Does it work for Android, if not are there plans for support for Android?

yakui should work on Android, but I have not tested it. As long as you have a functioning renderer, like wgpu, and a functioning windowing library, like winit, yakui will function.

No worries and thank you for your response :)

That seems to be good for my case.

Another question would be that if yakui has its own built in renderer if I want to make a standard application (not for game engines etc)?

So in other words it will function like retained graphics as well?

Right I see, thanks for your help :)

Sorry I have another question, does yakui have a locked in framework, like iced or bevy or are you free to code the way you want to?

yakui's primary focus is games. It should still be possible to make a normal application with yakui; you can use yakui-wgpu as the renderer.

So in other words it will function like retained graphics as well?

Sorta! The line between retained and immediate mode is fuzzy. yakui currently streams geometry into a buffer every frame, but caches other things.

You can integrate yakui into any kind of application. The only constraint is that you start a DOM, call some functions, then paint it to the screen. There's no framework for managing state or updates with yakui.

Would this change over time?

AWesome thank you mate :)
