Crate bevy_egui[−][src]

Expand description

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 (bevy_webgl2) 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.

Usage

Here’s a minimal usage example:

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

fn main() {
    App::build()
        .add_plugins(DefaultPlugins)
        .add_plugin(EguiPlugin)
        .add_system(ui_example.system())
        .run();
}

// Note the usage of `ResMut`. Even though `ctx` method doesn't require
// mutability, accessing the context from different threads will result
// into panic if you don't enable `egui/multi_threaded` feature.
fn ui_example(egui_context: Res<EguiContext>) {
    egui::Window::new("Hello").show(egui_context.ctx(), |ui| {
        ui.label("world");
    });
}
