Struct bevy_ecs::reflect::ReflectFromWorld

pub struct ReflectFromWorld(/* private fields */);

A struct used to operate on the reflected FromWorld trait of a type.

A ReflectFromWorld for type T can be obtained via bevy_reflect::TypeRegistration::data.

Implementations

impl ReflectFromWorld

pub fn from_world(&self, world: &mut World) -> Box<dyn Reflect>

Constructs default reflected FromWorld from world using from_world().

pub fn new(fns: ReflectFromWorldFns) -> Self

Create a custom implementation of ReflectFromWorld.

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(FromWorld)] bundle to generate a ReflectFromWorld implementation automatically.

See ReflectFromWorldFns for more information.

pub fn fn_pointers(&self) -> &ReflectFromWorldFns

The underlying function pointers implementing methods on ReflectFromWorld.

This is useful when you want to keep track locally of an individual function pointer.

Calling TypeRegistry::get followed by TypeRegistration::data::<ReflectFromWorld> can be costly if done several times per frame. Consider cloning ReflectFromWorld and keeping it between frames, cloning a ReflectFromWorld is very cheap.

If you only need a subset of the methods on ReflectFromWorld, use fn_pointers to get the underlying ReflectFromWorldFns and copy the subset of function pointers you care about.
