Hyperspeedcube VS Fyrox

https://github.com/HactarCE/Hyperspeedcube enables you to solve 4D cubes, the exploded visualization is standard but I think it is pretty cool

here is it in action https://www.youtube.com/watch?v=FCvn9-JvXgY&list=PLKwXjCUFqO...

also fyrox.rs

The Fyrox engine has a visual editor, you might want to check it out.

yes. check out https://bevyengine.org and https://fyrox.rs for whole engines. theres also things like macroquad, nannou, piet, femtovg for higher level drawing and rendering abstractions and if you want something lower level i highly recommend wgpu (graphics abstraction over Vulkan, WebGL, Metal and more)

https://fyrox.rs - closer to OOP, with composition over inheritance

At the moment I'd say it's bevy and fyrox both still in rapid development mode though so don't expect stable API's, will have to update your code with major releases

And there is fyrox _3D and 2D game engine written in Rust _ and editor fyroxed.

I successfully built my own retained-mode GUI library and made the editor with it for Fyrox Game Engine - https://github.com/FyroxEngine/Fyrox/tree/master/fyrox-ui . Only by using composition and message passing, I'm still excited how scalable this approach is. I built more than 50 various widgets with it - starting from simple buttons and ending node-based editors and docking managers. So I think you just need to pick a good approach that works fine with the language you're using.

I mean Fyrox is a full game engine with an editor, and even supports hot reloading plugins, so I'm guessing they've figured out the issues you're mentioning. I haven't read their source to code to figure out how it all works, but it's all here if you want to check it out: https://github.com/FyroxEngine/Fyrox

Kind of unfortunate timing there. The next generation of game engines are being written in rust, such as Fyrox: https://fyrox.rs/
