Struct bevy_ecs::reflect::ReflectBundle

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

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

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

Implementations

impl ReflectBundle

pub fn insert( &self, entity: &mut EntityWorldMut<'_>, bundle: &dyn Reflect, registry: &TypeRegistry )

Insert a reflected Bundle into the entity like insert().

pub fn apply<'a>( &self, entity: impl Into<EntityMut<'a>>, bundle: &dyn Reflect, registry: &TypeRegistry )

Uses reflection to set the value of this Bundle type in the entity to the given value.

Panics

Panics if there is no Bundle of the given type.

pub fn apply_or_insert( &self, entity: &mut EntityWorldMut<'_>, bundle: &dyn Reflect, registry: &TypeRegistry )

Uses reflection to set the value of this Bundle type in the entity to the given value or insert a new one if it does not exist.

pub fn remove(&self, entity: &mut EntityWorldMut<'_>)

Removes this Bundle type from the entity. Does nothing if it doesn’t exist.

pub fn new(fns: ReflectBundleFns) -> Self

Create a custom implementation of ReflectBundle.

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(Bundle)] bundle to generate a ReflectBundle implementation automatically.

See ReflectBundleFns for more information.

pub fn fn_pointers(&self) -> &ReflectBundleFns

The underlying function pointers implementing methods on ReflectBundle.

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

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

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