**Hey!** I'm the author of the crate, and I was born in Mariupol, Ukraine. When russians started the war in 2014, I moved to Kyiv. My parents, who had been staying in Mariupol till the start of the full-scale invasion, barely escaped the city alive. By the moment of writing (November 5th, 2023), we had [874 air raid alerts in Kyiv, and russians managed to bomb the city 132 times](https://air-alarms.in.ua/en/region/kyiv).

This crate provides an [Egui](https://github.com/emilk/egui) integration for the [Bevy](https://github.com/bevyengine/bevy) game engine.
**Trying out:**
An example WASM project is live at [mvlabat.github.io/bevy_egui_web_showcase](https://mvlabat.github.io/bevy_egui_web_showcase/index.html) [[source](https://github.com/mvlabat/bevy_egui_web_showcase)].
**Features:**
- Desktop and web platforms support
- Clipboard (web support is limited to the same window, see [rust-windowing/winit#1829](https://github.com/rust-windowing/winit/issues/1829))
- Opening URLs
- Multiple windows support (see [./examples/two_windows.rs](https://github.com/mvlabat/bevy_egui/blob/v0.20.1/examples/two_windows.rs))
`bevy_egui` can be compiled with using only `bevy` and `egui` as dependencies: `manage_clipboard` and `open_url` features,
that require additional crates, can be disabled.
## Dependencies
On Linux, this crate requires certain parts of [XCB](https://xcb.freedesktop.org/) to be installed on your system. On Debian-based systems, these can be installed with the following command:
```
$ sudo apt install libxcb-render0-dev libxcb-shape0-dev libxcb-xfixes0-dev
```
## Usage
Here's a minimal usage example:
```toml
# Cargo.toml
[dependencies]
bevy = "0.11"
bevy_egui = "0.23"
```
```rust
use bevy::prelude::*;
use bevy_egui::{egui, EguiContexts, EguiPlugin};
fn main() {
App::new()
.add_plugins(DefaultPlugins)
.add_plugins(EguiPlugin)
// Systems that create Egui widgets should be run during the `CoreSet::Update` set,
// or after the `EguiSet::BeginFrame` system (which belongs to the `CoreSet::PreUpdate` set).
.add_systems(Update, ui_example_system)
.run();
}
fn ui_example_system(mut contexts: EguiContexts) {
egui::Window::new("Hello").show(contexts.ctx_mut(), |ui| {
ui.label("world");
});
}
```
For a more advanced example, see [examples/ui.rs](https://github.com/mvlabat/bevy_egui/blob/v0.20.1/examples/ui.rs).
```bash
cargo run --example ui
```

**Note:** if you're looking for a `bevy_egui` version that supports `main` branch of Bevy, check out [open PRs](https://github.com/mvlabat/bevy_egui/pulls), there's a great chance we've already started working on the future Bevy release support.
