Struct amethyst_renderer::VisibilitySortingSystem

pub struct VisibilitySortingSystem { /* fields omitted */ }

Determine what entities are visible to the camera, and which are not. Will also sort transparent entities back to front based on distance from camera.

Note that this should run after GlobalTransform has been updated for the current frame, and before rendering occurs.

Methods

impl VisibilitySortingSystem

pub fn new() -> Self

Create new sorting system

Trait Implementations

impl<'a> System<'a> for VisibilitySortingSystem

type SystemData = (Entities<'a>, Write<'a, Visibility>, Option<Read<'a, ActiveCamera>>, ReadStorage<'a, Camera>, ReadStorage<'a, Transparent>, ReadStorage<'a, GlobalTransform>)

The resource bundle required to execute this system.

fn run(     &mut self,     (entities, visibility, active, camera, transparent, global): 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, res: &mut Resources)

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