Struct hecs::EntityBuilderClone
source · [−]pub struct EntityBuilderClone { /* private fields */ }
Expand description
Variant of EntityBuilder
that clones components on use
let mut world = World::new();
let mut builder = EntityBuilderClone::new();
builder.add(123).add("abc");
let bundle = builder.build();
let e = world.spawn(&bundle);
let f = world.spawn(&bundle); // `&bundle` can be used many times
assert_eq!(*world.get::<i32>(e).unwrap(), 123);
assert_eq!(*world.get::<&str>(e).unwrap(), "abc");
assert_eq!(*world.get::<i32>(f).unwrap(), 123);
assert_eq!(*world.get::<&str>(f).unwrap(), "abc");
Implementations
sourceimpl EntityBuilderClone
impl EntityBuilderClone
sourcepub fn add<T: Component + Clone>(&mut self, component: T) -> &mut Self
pub fn add<T: Component + Clone>(&mut self, component: T) -> &mut Self
Add component
to the entity.
If the bundle already contains a component of type T
, it will be dropped and replaced with
the most recently added one.
sourcepub fn add_bundle(&mut self, bundle: impl DynamicBundleClone) -> &mut Self
pub fn add_bundle(&mut self, bundle: impl DynamicBundleClone) -> &mut Self
Add all components in bundle
to the entity.
If the bundle contains any component which matches the type of a component
already in the EntityBuilder
, the newly added component from the bundle
will replace the old component and the old component will be dropped.
sourcepub fn build(self) -> BuiltEntityClone
pub fn build(self) -> BuiltEntityClone
Convert into a value whose shared references are DynamicBundle
s suitable for repeated
spawning
sourcepub fn get_mut<T: Component>(&mut self) -> Option<&mut T>
pub fn get_mut<T: Component>(&mut self) -> Option<&mut T>
Uniquely borrow the component of type T
, if it exists
sourcepub fn component_types(&self) -> impl Iterator<Item = TypeId> + '_
pub fn component_types(&self) -> impl Iterator<Item = TypeId> + '_
Enumerate the types of the entity builder’s components
