Struct bevy::ui::IsDefaultUiCamera

pub struct IsDefaultUiCamera;

Marker used to identify default cameras, they will have priority over the PrimaryWindow camera.

This is useful if the PrimaryWindow has two cameras, one of them used just for debug purposes and the user wants a way to choose the default Camera without having to add a TargetCamera to the root node.

Another use is when the user wants the Ui to be in another window by default, all that is needed is to place this component on the camera

fn spawn_camera(mut commands: Commands) {
    let another_window = commands.spawn(Window {
        title: String::from("Another window"),
        ..Default::default()
    }).id();
    commands.spawn((
        Camera2dBundle {
            camera: Camera {
                target: RenderTarget::Window(WindowRef::Entity(another_window)),
                ..Default::default()
            },
            ..Default::default()
        },
        // We add the Marker here so all Ui will spawn in
        // another window if no TargetCamera is specified
        IsDefaultUiCamera
    ));
}
