Struct hecs::EntityBuilder [−][src]
pub struct EntityBuilder { /* fields omitted */ }
Helper for incrementally constructing a bundle of components with dynamic component types
Prefer reusing the same builder over creating new ones repeatedly.
let mut world = World::new(); let mut builder = EntityBuilder::new(); builder.add(123).add("abc"); let e = world.spawn(builder.build()); // builder can now be reused assert_eq!(*world.get::<i32>(e).unwrap(), 123); assert_eq!(*world.get::<&str>(e).unwrap(), "abc");
Implementations
impl EntityBuilder
[src]
impl EntityBuilder
[src]pub fn add<T: Component>(&mut self, component: T) -> &mut Self
[src]
pub fn add<T: Component>(&mut self, component: T) -> &mut Self
[src]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.
pub fn add_bundle(&mut self, bundle: impl DynamicBundle) -> &mut Self
[src]
pub fn add_bundle(&mut self, bundle: impl DynamicBundle) -> &mut Self
[src]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.
pub fn get_mut<T: Component>(&mut self) -> Option<&mut T>
[src]
pub fn get_mut<T: Component>(&mut self) -> Option<&mut T>
[src]Uniquely borrow the component of type T
, if it exists
pub fn component_types(&self) -> impl Iterator<Item = TypeId> + '_
[src]
pub fn component_types(&self) -> impl Iterator<Item = TypeId> + '_
[src]Enumerate the types of the entity builder’s components
pub fn build(&mut self) -> BuiltEntity<'_>
[src]
pub fn build(&mut self) -> BuiltEntity<'_>
[src]Construct a Bundle
suitable for spawning
