Struct EntityLayer 

pub struct EntityLayer { /* private fields */ }

A [Component] containing Minecraft entities.

Implementations

impl EntityLayer

pub fn new(server: &Server) -> Self

Creates a new entity layer.

pub fn entities_at<P: Into<ChunkPos>>( &self, pos: P, ) -> impl Iterator<Item = Entity> + Clone + '_

Returns an iterator over all entities contained within the given chunk position in this layer.

Trait Implementations

impl Component for EntityLayer

where Self: Send + Sync + 'static,

const STORAGE_TYPE: StorageType = bevy_ecs::component::StorageType::Table

A constant indicating the storage type used for this component.

type Mutability = Mutable

A marker type to assist Bevy with determining if this component is mutable, or immutable. Mutable components will have [Component<Mutability = Mutable>], while immutable components will instead have [Component<Mutability = Immutable>].

fn register_required_components( _requiree: ComponentId, required_components: &mut RequiredComponentsRegistrator<'_, '_>, )

Registers required components.

fn clone_behavior() -> ComponentCloneBehavior

Called when registering this component, allowing to override clone function (or disable cloning altogether) for this component.

fn relationship_accessor() -> Option<ComponentRelationshipAccessor<Self>>

Returns [ComponentRelationshipAccessor] required for working with relationships in dynamic contexts.

fn on_add() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_add [ComponentHook] for this [Component] if one is defined.

fn on_insert() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_insert [ComponentHook] for this [Component] if one is defined.

fn on_discard() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_discard [ComponentHook] for this [Component] if one is defined.

fn on_remove() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_remove [ComponentHook] for this [Component] if one is defined.

fn on_despawn() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_despawn [ComponentHook] for this [Component] if one is defined.

fn map_entities<E>(_this: &mut Self, _mapper: &mut E)

where E: EntityMapper,

Maps the entities on this component using the given [EntityMapper]. This is used to remap entities in contexts like scenes and entity cloning. When deriving [Component], this is populated by annotating fields containing entities with #[entities]

impl Debug for EntityLayer

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

Formats the value using the given formatter.

impl Layer for EntityLayer

type ExceptWriter<'a> = ExceptWriter<'a>

Packet writer returned by except_writer.

type ViewWriter<'a> = ViewWriter<'a>

Packet writer returned by view_writer.

type ViewExceptWriter<'a> = ViewExceptWriter<'a>

Packet writer returned by view_except_writer.

type RadiusWriter<'a> = RadiusWriter<'a>

Packet writer returned by radius_writer.

type RadiusExceptWriter<'a> = RadiusExceptWriter<'a>

Packet writer returned by radius_except_writer.

fn except_writer(&mut self, except: Entity) -> Self::ExceptWriter<'_>

Returns a packet writer which sends packets to all viewers not identified by except.

fn view_writer(&mut self, pos: impl Into<ChunkPos>) -> Self::ViewWriter<'_>

Returns a packet writer which sends packets to viewers in view of the chunk position pos.

fn view_except_writer( &mut self, pos: impl Into<ChunkPos>, except: Entity, ) -> Self::ViewExceptWriter<'_>

Returns a packet writer which sends packets to viewers in view of the chunk position pos and not identified by except.

fn radius_writer( &mut self, center: impl Into<BlockPos>, radius: u32, ) -> Self::RadiusWriter<'_>

Returns a packet writer which sends packets to viewers within radius blocks of the block position pos.

fn radius_except_writer( &mut self, center: impl Into<BlockPos>, radius: u32, except: Entity, ) -> Self::RadiusExceptWriter<'_>

Returns a packet writer which sends packets to viewers within radius blocks of the block position pos and not identified by except.

impl WritePacket for EntityLayer

fn write_packet_fallible<P>(&mut self, packet: &P) -> Result<()>

where P: Packet + Encode,

Writes a packet to this object. The result of encoding the packet is returned.

fn write_packet_bytes(&mut self, bytes: &[u8])

Copies raw packet data directly into this object. Don’t use this unless you know what you’re doing.

fn write_packet<P>(&mut self, packet: &P)

where P: Packet + Encode,

Writes a packet to this object. Encoding errors are typically logged and discarded.
