Bevy GUI

[g-codx]

I find some pluses in creating a complex desktop ui using bevy.

• I like bevy
• ecs is flexible and convenient
• a lot of information about the engine

What disadvantages will i face ?

Disadvantages:

• bevy_ui is extremely primitive, doesn't have any widget beside "button". You'll have to define every widgets yourself
• bevy_ui doesn't have an input solution, you'll have to inovate/reinvete the wheel to manage inputs
• bevy_ui doesn't have state management, you'll have to design a really nice bridge between the ECS world and your UI declaration layer to make it work
• bevy_ui has poor scene support, so you'll have to write a bit of code to get hot reloading and file-defined

Basically you are going to write a UI framework on top of bevy. If you don't want to write a UI framework, but rather want to write a desktop application, I'd recommend either using a pre-existing bevy ui framework (such as bevy_egui, kayak or belly) or not using bevy for your desktop UI.

Note that existing bevy ui frameworks are unstable and fairly untested, so you run the risk of hitting a snag fairly quickly.
