Trait Implementations

impl<T> Default for Camera2DSystem<T>

fn default() -> Self

Returns the "default value" for a type.

impl<'system, T> System<'system> for Camera2DSystem<T> where     T: 'static + Send + Sync + Float + FromPrimitive,     &'a T: Sub<&'b T, Output = T> + Add<&'b T, Output = T> + Div<&'b T, Output = T> + Mul<&'b T, Output = T> + Neg<Output = T>,

type SystemData = (Read<'system, ScreenSize>, ReadStorage<'system, Transform2D<T>>, WriteStorage<'system, Camera2D<T>>)

The resource bundle required to execute this system.

fn run(&mut self, (size, transforms_2d, cameras_2d): 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.
