Methods

impl<'a> EntitiesTransaction<'a>

fn create(&mut self) -> Entity

fn destroy(&mut self, entity: Entity)

Destroys an Entity.

Entity destructions are deferred until after the system has completed execution. All related data stored in entity resources will also be removed at this time.

fn is_alive(&self, entity: &Entity) -> bool

Determines if the given Entity is still alive.

fn by_index(&self, index: Index) -> Entity

Gets the currently living Entity with the given Index.

fn to_change_set(self) -> EntityChangeSet
