Struct bevy_ui_navigation::bundles::MenuSeed

pub struct MenuSeed { /* private fields */ }

A “seed” for creation of a NavMenu.

Internally, bevy_ui_navigation uses a special component to mark UI nodes as “menus”, this tells the navigation algorithm to add that component to this Entity.

Implementations

impl MenuSeed

pub fn marking<T: Component>(self, marker: T) -> MarkingMenuSeed<T>

Create a NavMenu that will automatically mark all it’s contained Focusables with T.

marker is the component that will be added to all Focusable entities contained within this menu.

Trait Implementations

impl Bundle for MenuSeed

SAFE: ComponentId is returned in field-definition-order. [from_components] and [get_components] use field-definition-order

fn component_ids(
    components: &mut Components,
    storages: &mut Storages
) -> Vec<ComponentId>

Gets this [Bundle]’s component ids, in the order of this bundle’s [Component]s

unsafe fn from_components(func: impl FnMut() -> *mut u8) -> Self

Calls func, which should return data for each component in the bundle, in the order of this bundle’s [Component]s

fn get_components(self, func: impl FnMut(*mut u8))

Calls func on each value, in the order of this bundle’s [Component]s. This will std::mem::forget the bundle fields, so callers are responsible for dropping the fields if that is desirable.

impl Clone for MenuSeed

fn clone(&self) -> MenuSeed

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
