Crate bevy_megaui

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

bevy_megaui depends solely on megaui and bevy with only render feature required.

Trying out

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

Note that in order to use bevy_megauiin WASM you need bevy_webgl2 of at least 0.4.1 version.

Usage

Here’s a minimal usage example:

use bevy::prelude::*;
use bevy_megaui::{
    megaui::{hash, Vector2},
    MegaUiContext, MegaUiPlugin,
};

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

fn ui_example(_world: &mut World, resources: &mut Resources) {
    let mut ui = resources.get_thread_local_mut::<MegaUiContext>().unwrap();

    ui.draw_window(
        hash!(),
        Vector2::new(5.0, 5.0),
        Vector2::new(100.0, 50.0),
        None,
        |ui| {
            ui.label(None, "Hello world!");
        },
    );
}
