Struct bevy::prelude::Entity

pub struct Entity(_);

Lightweight unique ID of an entity

Obtained from World::spawn. Can be stored to refer to an entity in the future.

Implementations

impl Entity

pub fn new() -> Entity

pub fn from_id(id: u32) -> Entity

pub fn id(self) -> u32

Extract a transiently unique identifier

No two simultaneously-live entities share the same ID, but dead entities' IDs may collide with both live and dead entities. Useful for compactly representing entities within a specific snapshot of the world, such as when serializing.

Trait Implementations

impl Clone for Entity

fn clone(&self) -> Entity

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Entity

impl Debug for Entity

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

Formats the value using the given formatter.

impl DeserializeProperty for Entity

fn deserialize(
    deserializer: &mut dyn Deserializer,
    property_type_registry: &PropertyTypeRegistry
) -> Result<Box<dyn Property + 'static>, Error>

impl Eq for Entity

impl Hash for Entity

fn hash<__H>(&self, state: &mut __H) where
    __H: Hasher, 

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given [Hasher].

impl Ord for Entity

fn cmp(&self, other: &Entity) -> Ordering

This method returns an [Ordering] between self and other.

#[must_use]fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

#[must_use]fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

#[must_use]fn clamp(self, min: Self, max: Self) -> Self

🔬 This is a nightly-only experimental API. (clamp)

Restrict a value to a certain interval.

impl PartialEq<Entity> for Entity

fn eq(&self, other: &Entity) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Entity) -> bool

This method tests for !=.

impl PartialOrd<Entity> for Entity

fn partial_cmp(&self, other: &Entity) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Entity) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Entity) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Entity) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Entity) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Property for Entity

fn type_name(&self) -> &str

fn any(&self) -> &(dyn Any + 'static)

fn property_type(&self) -> PropertyType

fn as_properties(&self) -> Option<&(dyn Properties + 'static)>

impl Query for Entity

type Fetch = EntityFetch

impl Serialize for Entity

fn serialize<S>(
    &self,
    serializer: S
) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error> where
    S: Serializer,
