Struct Parent 

pub struct Parent(pub Entity);

父实体组件

标识实体的父实体，用于构建变换层次结构。

示例

use anvilkit_ecs::prelude::*;
 
let mut world = World::new();
 
let parent_entity = world.spawn((
    Transform::default(),
    GlobalTransform::default(),
)).id();
 
let child_entity = world.spawn((
    Transform::default(),
    GlobalTransform::default(),
    Parent(parent_entity),
)).id();

Tuple Fields

0: Entity

Implementations

impl Parent

pub fn new(entity: Entity) -> Parent

创建新的父实体组件

pub fn get(&self) -> Entity

获取父实体

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

设置父实体

Trait Implementations

impl Clone for Parent

fn clone(&self) -> Parent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Component for Parent

where Parent: Send + Sync + 'static,

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

A constant indicating the storage type used for this component.

fn register_component_hooks(_hooks: &mut ComponentHooks)

Called when registering this component, allowing mutable access to its ComponentHooks.

impl Debug for Parent

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

Formats the value using the given formatter.

impl PartialEq for Parent

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
