Trait Implementations

impl ChildBuild for WorldChildBuilder<'_>

type SpawnOutput<'a> = EntityWorldMut<'a> where WorldChildBuilder<'_>: 'a

Spawn output type. Both spawn and spawn_empty return an implementation of this type so that children can be operated on via method-chaining. Implementations of ChildBuild reborrow self when spawning entities (see Commands::spawn_empty and World::get_entity_mut). Lifetime 'a corresponds to this reborrowed self, and Self outlives it.

fn spawn(&mut self, bundle: impl Bundle) -> EntityWorldMut<'_>

Spawns an entity with the given bundle and inserts it into the parent entity’s Children. Also adds Parent component to the created entity.

fn spawn_empty(&mut self) -> EntityWorldMut<'_>

Spawns an Entity with no components and inserts it into the parent entity’s Children. Also adds Parent component to the created entity.

fn parent_entity(&self) -> Entity

Returns the parent entity.

fn enqueue_command<C>(&mut self, command: C) -> &mut WorldChildBuilder<'_>

where C: Command,

Adds a command to be executed, like Commands::queue.

impl<'w> Debug for WorldChildBuilder<'w>

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.
