Struct specs_blit::RenderSystem

pub struct RenderSystem;

Specs system for rendering to a buffer.

Note: This can only be used in conjunction with a .with_thread_local() function in specs and not with a normal .with() call.

use specs::prelude::*;
use specs_blit::RenderSystem;

let mut dispatcher = DispatcherBuilder::new()
    // Expose the sprite render system to specs
    .with_thread_local(RenderSystem)
    .build();

Trait Implementations

impl<'a> System<'a> for RenderSystem

type SystemData = (Write<'a, PixelBuffer>, ReadStorage<'a, Sprite>)

The resource bundle required to execute this system.

fn run(&mut self, (buffer, sprites): 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.
