Struct Viewport 

pub struct Viewport {
    pub size: Vec2,
    pub clear: Color,
    pub scale_factor: f32,
    pub monitor_scale: Option<f32>,
    pub monitor_size: Option<Vec2>,
    pub monitor_name: Option<String>,
}

Window viewport, inserted as a Resource into both the main and render worlds. The window plugin writes both copies on every resize.

Fields

size: Vec2

Logical-pixel window size. The window backend divides the raw PhysicalSize it receives from winit by scale_factor before writing here, so layout consumers see the same coordinate space CSS / pointer events do.

clear: Color

Background clear color.

scale_factor: f32

Current window scale factor (logical -> physical multiplier). Written by the window backend on startup, Resized, and ScaleFactorChanged. Defaults to 1.0 so headless / pre-window code paths can multiply through unconditionally.

monitor_scale: Option<f32>

HiDPI factor of the current monitor (e.g. 1.0, 1.5, 2.0); written by the window backend on startup and MonitorChanged. None while monitor info is unavailable.

monitor_size: Option<Vec2>

Physical-pixel size of the current monitor; written by the window backend.

monitor_name: Option<String>

Monitor name reported by winit (for example "DELL U2719D").

Trait Implementations

impl Clone for Viewport

fn clone(&self) -> Viewport

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Component for Viewport

where Self: Send + Sync + 'static,

const STORAGE_TYPE: StorageType = bevy_ecs::component::StorageType::SparseSet

A constant indicating the storage type used for this component.

type Mutability = Mutable

A marker type to assist Bevy with determining if this component is mutable, or immutable. Mutable components will have Component<Mutability = Mutable>, while immutable components will instead have Component<Mutability = Immutable>.

fn register_required_components( _requiree: ComponentId, required_components: &mut RequiredComponentsRegistrator<'_, '_>, )

Registers required components.

fn clone_behavior() -> ComponentCloneBehavior

Called when registering this component, allowing to override clone function (or disable cloning altogether) for this component.

fn relationship_accessor() -> Option<ComponentRelationshipAccessor<Self>>

Returns [ComponentRelationshipAccessor] required for working with relationships in dynamic contexts.

fn on_add() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_add [ComponentHook] for this Component if one is defined.

fn on_insert() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_insert [ComponentHook] for this Component if one is defined.

fn on_discard() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_discard [ComponentHook] for this Component if one is defined.

fn on_remove() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_remove [ComponentHook] for this Component if one is defined.

fn on_despawn() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_despawn [ComponentHook] for this Component if one is defined.

fn map_entities<E>(_this: &mut Self, _mapper: &mut E)

where E: EntityMapper,

Maps the entities on this component using the given EntityMapper. This is used to remap entities in contexts like scenes and entity cloning. When deriving Component, this is populated by annotating fields containing entities with #[entities]

impl Debug for Viewport

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

Formats the value using the given formatter.

impl Default for Viewport

fn default() -> Self

Returns the “default value” for a type.

impl Resource for Viewport

where Self: Send + Sync + 'static,
