Trait Implementations

impl<'a> System<'a> for UiSystem

type SystemData = (Entities<'a>, WriteStorage<'a, UiText>, WriteStorage<'a, TextEditing>, ReadStorage<'a, UiTransform>, Write<'a, UiFocused>, Read<'a, EventChannel<Event>>, Read<'a, Time>, ReadExpect<'a, ScreenDimensions>)

The resource bundle required to execute this system.

fn run(     &mut self,     (entities, text, editable, transform, focused, events, time, screen_dimensions): Self::SystemData )

Executes the system with the required system data.

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

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

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].
