This crate provides a Egui integration for the Bevy game engine.

Trying out:

An example WASM project is live at mvlabat.github.io/bevy_egui_web_showcase [source].

Features:

• Desktop and web platforms support
• Clipboard (web support is limited to the same window, see rust-windowing/winit#1829)
• Opening URLs
• Multiple windows support (see ./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.

On Linux, this crate requires certain parts of XCB are installed on your system. On Debian-based systems, these can be installed with the command:

$ sudo apt install libxcb-render0-dev libxcb-shape0-dev libxcb-xfixes0-dev

Here's a minimal usage example:

# Cargo.toml
[dependencies]
bevy = "0.8"
bevy_egui = "0.15"

use bevy::prelude::*;
use bevy_egui::{egui, EguiContext, EguiPlugin};

fn main() {
    App::new()
        .add_plugins(DefaultPlugins)
        .add_plugin(EguiPlugin)
        // Systems that create Egui widgets should be run during the `CoreStage::Update` stage,
        // or after the `EguiSystem::BeginFrame` system (which belongs to the `CoreStage::PreUpdate` stage).
        .add_system(ui_example)
        .run();
}

fn ui_example(mut egui_context: ResMut<EguiContext>) {
    egui::Window::new("Hello").show(egui_context.ctx_mut(), |ui| {
        ui.label("world");
    });
}

For a more advanced example, see examples/ui.rs.

cargo run --example ui

Note: if you're looking for a bevy_egui version that supports main branch of Bevy, check out open PRs, there's a great chance we've already started working on the future Bevy release support.
