Struct amethyst_controls::FreeRotationSystem

pub struct FreeRotationSystem { /* fields omitted */ }

The system that manages the view rotation.

Controlled by the mouse. Goes into an inactive state if the window is not focused (WindowFocus resource).

Can be manually disabled by making the mouse visible using the HideCursor resource: HideCursor.hide = false

Methods

impl FreeRotationSystem

pub fn new(
    sensitivity_x: f32,
    sensitivity_y: f32,
    event_reader: ReaderId<Event>
) -> Self

Constructs a new FreeRotationSystem.

Trait Implementations

impl Debug for FreeRotationSystem

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<'system_desc_a, 'system_desc_b> SystemDesc<'system_desc_a, 'system_desc_b, FreeRotationSystem> for FreeRotationSystemDesc

fn build(self, world: &mut World) -> FreeRotationSystem

Builds and returns a System.

impl<'a> System<'a> for FreeRotationSystem

type SystemData = (Read<'a, EventChannel<Event>>, WriteStorage<'a, Transform>, ReadStorage<'a, FlyControlTag>, Read<'a, WindowFocus>, Read<'a, HideCursor>)

The resource bundle required to execute this system.

fn run(&mut self, (events, transform, tag, focus, hide): 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.
