}

fn setup(mut commands: Commands) {
    commands.spawn(Camera2dBundle { ..default() });
}

fn show_fps(diagnostics: Res<DiagnosticsStore>, mut debug_res: ResMut<DebugResource>) {
    if let Some(value) = diagnostics
        .get(&FrameTimeDiagnosticsPlugin::FPS)
        .and_then(|fps| fps.smoothed())
    {
        debug_res.insert("Fps", format!("{:.2}", value));
