type SystemData = (Entities<'a>, WriteStorage<'a, UiTransform>, WriteStorage<'a, Anchored>, ReadStorage<'a, Parent>, ReadExpect<'a, ScreenDimensions>)

The resource bundle required to execute this system.

fn run(     &mut self,     (entities, transform, anchor, parent, screen_dim): Self::SystemData )

Executes the system with the required system data.

Return the accessor from the [SystemData].

fn setup(&mut self, res: &mut Resources)

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