    parent_events_id: ReaderId<HierarchyEvent>
) -> TransformSystem

Trait Implementations

impl<'a, 'b> SystemDesc<'a, 'b, TransformSystem> for TransformSystemDesc

fn build(self, world: &mut World) -> TransformSystem

Builds and returns a System.

impl Debug for TransformSystem

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<'a> System<'a> for TransformSystem

type SystemData = (Entities<'a>, ReadExpect<'a, ParentHierarchy>, WriteStorage<'a, Transform>, ReadStorage<'a, Parent>)

The resource bundle required to execute this system.

fn run(&mut self, (entities, hierarchy, locals, parents): Self::SystemData)

Executes the system with the required system data.

fn running_time(&self) -> RunningTime

Returns a hint how long the system needs for running. This is used to optimize the way they're executed (might allow more parallelization).

fn accessor(&'b self) -> AccessorCow<'a, 'b, Self>

Return the accessor from the [SystemData].

fn setup(&mut self, world: &mut World)

Sets up the World using Self::SystemData::setup.

fn dispose(self, world: &mut World)

Performs clean up that requires resources from the World. This commonly removes components from world which depend on external resources.
