Common trait for all Entities like objects.
Allows access and modification of Send
components. Useful to
create functions that can be used from different systems and need
an Entities like parameter.
Required methods
pub fn component_for<C>(&self, entity: &Entity) -> Option<Ptr<'_, C>> where
C: ComponentSend,
<C as Component>::Storage: for<'s> Storage<'s, C>,
[src]
C: ComponentSend,
<C as Component>::Storage: for<'s> Storage<'s, C>,
Returns a component for reading for the passed entity
let e1 = world.new_entity() .add(Position{x: 0., y: 0.}) .build(); let entities = world.entities(); let pos = entities.component_for::<Position>(&e1).unwrap();
pub fn component_for_mut<C>(&self, entity: &Entity) -> Option<PtrMut<'_, C>> where
C: ComponentSend,
<C as Component>::Storage: for<'s> Storage<'s, C>,
[src]
C: ComponentSend,
<C as Component>::Storage: for<'s> Storage<'s, C>,
Returns a component for writing for the passed entity
let e1 = world.new_entity() .add(Position{x: 0., y: 0.}) .build(); let entities = world.entities(); let mut pos = entities.component_for_mut::<Position>(&e1).unwrap();
pub fn has_component<C>(&self, entity: &Entity) -> bool where
C: 'static,
[src]
C: 'static,
Returns true if the entity has the specified component
let e1 = world.new_entity() .add(Position{x: 0., y: 0.}) .build(); let entities = world.entities(); assert!(entities.has_component::<Position>(&e1));
pub fn tree_node_for<C>(&self, entity: &Entity) -> Option<NodePtr<'_, C>> where
C: ComponentSend,
<C as Component>::Storage: for<'b> HierarchicalStorage<'b, C>,
[src]
C: ComponentSend,
<C as Component>::Storage: for<'b> HierarchicalStorage<'b, C>,
Returns the node for a hierarchical component
pub fn tree_node_for_mut<C>(&self, entity: &Entity) -> Option<NodePtrMut<'_, C>> where
C: ComponentSend,
<C as Component>::Storage: for<'b> HierarchicalStorage<'b, C>,
[src]
C: ComponentSend,
<C as Component>::Storage: for<'b> HierarchicalStorage<'b, C>,
Returns the node for a hierarchical component for writing
pub fn storage_for<'r, S>(&'r self) -> Sto<'r, S> where
S: UnorderedDataSend<'r>,
[src]
S: UnorderedDataSend<'r>,
Storage for the operator passed as type parameter
Calling iter_for can be slow if it needs to be called lots of times. In those cases
calling instead storage_for
once and then iter() on it multiple times can make performance
much better
let mut storage = entities.storage_for_mut::<(Write<Position>, Read<Velocity>)>().unwrap(); for i in 0..1000000 { for (pos, vel) in storage.iter_mut() { pos.x += vel.x; pos.y += vel.y; } }
