Struct EntityLayer 

pub struct EntityLayer { /* private fields */ }

A Component containing Minecraft entities.

Implementations

impl EntityLayer

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

Creates a new entity layer.

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

where P: Into<ChunkPos>,

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

Trait Implementations

impl Component for EntityLayer

where EntityLayer: 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<EntityLayer>>

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<(), Error>

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, ) -> <EntityLayer as Layer>::ExceptWriter<'_>

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

fn view_writer( &mut self, pos: impl Into<ChunkPos>, ) -> <EntityLayer as Layer>::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, ) -> <EntityLayer as Layer>::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, ) -> <EntityLayer as Layer>::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, ) -> <EntityLayer as Layer>::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<(), Error>

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.
