_The godot_egui backend powering a new inventory UI for The Process_

[The Process] by @setzer22 is an upcoming game about factory building,

process management, and carrot production,

built with Rust using the Godot game engine!

Continuing with last month's migration of old GDScript code to ECS in Rust, this

month's main focus has been on porting the GUI code. This has resulted in

the birth of a Godot integration for [egui](https://docs.rs/egui/) that now

powers the game's interface.

This month has seen the following changes and improvements:

- Finished migration of character controller code to ECS style. Now with [300%

more jumps!](https://twitter.com/PlayTheProcess/status/1413081233396011012)

- Implemented [better ambient

lighting](https://twitter.com/PlayTheProcess/status/1413943539160031246) and

enable using different skies for radiance and display. This required a [forked

godot version](https://github.com/setzer22/godot/tree/feature/cosmetic_sky).

- Implement a [new inventory and

toolbar](https://twitter.com/PlayTheProcess/status/1417774452012724226)

interface using egui.

- Integrated the [puffin

profiler](https://twitter.com/PlayTheProcess/status/1420277428199559174) into

the game using the godot_egui integration.

[godot_egui] is an integration of the [egui](https://github.com/emilk/egui)

crate for the Godot engine using Rust, enabling highly dynamic and performant

user interfaces in an immediate-mode style in Godot.

Godot has a great GUI system, so why use `godot_egui` instead? A more in-depth

rationale can be found in the crate's README, but the main reason is to provide

a GUI system for godot-rust games that is closer to Rust's data driven

philosophy.

Unlike other egui integrations, `godot_egui` has the special feature of being

embedded as a custom Godot scene tree node. This effectively allows combining

Godot's retained mode UI and container-based placement with the simplicity of

immediate-mode style GUI code of `egui`, getting the best of both worlds.

The [github repository](https://github.com/setzer22/godot-egui) has an example

project and usage instructions to get you started with immediate-mode GUI

programming with Godot and Rust!
