Struct shine_ecs::entities::WriteEntities

pub struct WriteEntities<'a> { /* fields omitted */ }

Grant mutable access to the entities inside a System

Methods from Deref<Target = EntityStore>

pub fn is_empty(&self) -> bool

pub fn len(&self) -> usize

pub fn create(&mut self) -> Entity

Allocates a new entity

pub fn create_with_id(&mut self, id: usize) -> Option<Entity>

Allocates an entity with the given id. Usually used to keep two system in sync.

pub fn destroy(&mut self, entity: Entity)

Destroy an entity

pub fn raised(&self) -> &STVector

pub fn drain_raised(&mut self) -> DrainIter<UnitStore>

pub fn killed(&self) -> &STVector

pub fn drain_killed(&mut self) -> DrainIter<UnitStore>

Trait Implementations

impl<'a> Deref for WriteEntities<'a>

type Target = EntityStore

The resulting type after dereferencing.

fn deref(&self) -> &EntityStore

Dereferences the value.

impl<'a> DerefMut for WriteEntities<'a>

fn deref_mut(&mut self) -> &mut EntityStore

Mutably dereferences the value.

impl<'a> SystemData<'a> for WriteEntities<'a>

fn setup(_: &mut World)

Sets up the system data for fetching it from the World.

fn fetch(res: &'a World) -> Self

Fetches the system data from World. Note that this is only specified for one concrete lifetime 'a, you need to implement the SystemData trait for every possible lifetime.

fn reads() -> Vec<ResourceId>

Returns all read dependencies as fetched from Self::fetch.

fn writes() -> Vec<ResourceId>

Returns all write dependencies as fetched from Self::fetch.
