Usage:

1. Add this to your Stage: rust .with_pass(amethyst_imgui::DrawUi::default())
2. Add this to GameDataBuilder: rust GameDataBuilder::default() .with(amethyst_imgui::BeginFrame::default(), "imgui_begin", &[]) .with_barrier() // --- everything else --- .with_barrier() .with(amethyst_imgui::EndFrame::default(), "imgui_end", &["imgui_begin"]);
3. Use it in any System: rust amethyst_imgui::with(|ui| { ui.show_demo_window(&mut true); });

It's annoying that my window/widget state is reset:

Add an ImguiIni resource. rust world.add_resource(amethyst_imgui::ImguiIni::new("imgui.ini"));

Example:

cargo run --example demo_window
