Struct bevy::ecs::prelude::ReflectComponent
pub struct ReflectComponent(_);
Expand description
A struct used to operate on reflected Component
of a type.
A ReflectComponent
for type T
can be obtained via
[bevy_reflect::TypeRegistration::data
].
Implementations§
§impl ReflectComponent
impl ReflectComponent
pub fn apply_or_insert(
&self,
world: &mut World,
entity: Entity,
component: &(dyn Reflect + 'static)
)
pub fn apply_or_insert(
&self,
world: &mut World,
entity: Entity,
component: &(dyn Reflect + 'static)
)
pub fn reflect<'a>(
&self,
world: &'a World,
entity: Entity
) -> Option<&'a (dyn Reflect + 'static)>
pub fn reflect<'a>(
&self,
world: &'a World,
entity: Entity
) -> Option<&'a (dyn Reflect + 'static)>
Gets the value of this Component
type from the entity as a reflected reference.
pub fn reflect_mut<'a>(
&self,
world: &'a mut World,
entity: Entity
) -> Option<Mut<'a, dyn Reflect + 'static>>
pub fn reflect_mut<'a>(
&self,
world: &'a mut World,
entity: Entity
) -> Option<Mut<'a, dyn Reflect + 'static>>
Gets the value of this Component
type from the entity as a mutable reflected reference.
pub unsafe fn reflect_unchecked_mut<'a>(
&self,
world: &'a World,
entity: Entity
) -> Option<Mut<'a, dyn Reflect + 'static>>
pub unsafe fn reflect_unchecked_mut<'a>(
&self,
world: &'a World,
entity: Entity
) -> Option<Mut<'a, dyn Reflect + 'static>>
Safety
This method does not prevent you from having two mutable pointers to the same data, violating Rust’s aliasing rules. To avoid this:
- Only call this method in an exclusive system to avoid sharing across threads (or use a scheduler that enforces safe memory access).
- Don’t call this method more than once in the same scope for a given
Component
.
pub fn copy(
&self,
source_world: &World,
destination_world: &mut World,
source_entity: Entity,
destination_entity: Entity
)
pub fn copy(
&self,
source_world: &World,
destination_world: &mut World,
source_entity: Entity,
destination_entity: Entity
)
pub fn new(fns: ReflectComponentFns) -> ReflectComponent
pub fn new(fns: ReflectComponentFns) -> ReflectComponent
Create a custom implementation of ReflectComponent
.
This is an advanced feature, useful for scripting implementations, that should not be used by most users unless you know what you are doing.
Usually you should derive Reflect
and add the #[reflect(Component)]
component
to generate a ReflectComponent
implementation automatically.
See ReflectComponentFns
for more information.
