fn add_component_unchecked( &mut self, entity: EntityId, component: Self::Component, )
Adds component to entity, multiple components can be added at the same time using a tuple.
This function does not check entity is alive. It’s possible to add components to removed entities.
Use Entities::add_component if you’re unsure.
§Example
use shipyard::{AddComponent, Component, EntitiesViewMut, ViewMut, World};
#[derive(Component)]
struct U32(u32);
let world = World::new();
let (mut entities, mut u32s) = world.borrow::<(EntitiesViewMut, ViewMut<U32>)>().unwrap();
let entity = entities.add_entity((), ());
u32s.add_component_unchecked(entity, U32(0));
