Struct SliderValue 

pub struct SliderValue {
    pub value: f32,
    pub min: f32,
    pub max: f32,
    pub step: Option<f32>,
}

Bounded scalar state for <slider> entities. value is held in [min, max]; the runtime emits on_slider(id, value) on drag or track click.

Fields

value: f32

Current value, clamped to [min, max].

min: f32

Lower bound.

max: f32

Upper bound.

step: Option<f32>

Authored step="..." increment for keyboard arrows and wheel notches. None falls back to (max - min) / 100 - the <input type=range> browser default of 100 discrete positions (see Self::step_size).

Implementations

impl SliderValue

pub fn step_size(&self) -> f32

Effective step increment: the authored Self::step, or (max - min) / 100 when unset.

Trait Implementations

impl Clone for SliderValue

fn clone(&self) -> SliderValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Component for SliderValue

where Self: Send + Sync + 'static,

const STORAGE_TYPE: StorageType = bevy_ecs::component::StorageType::Table

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 SliderValue

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

Formats the value using the given formatter.

impl Default for SliderValue

fn default() -> Self

Returns the “default value” for a type.

impl From<&SliderValue> for A11yRole

fn from(_: &SliderValue) -> Self

Converts to this type from the input type.

impl From<&SliderValue> for A11yValue

fn from(s: &SliderValue) -> Self

Converts to this type from the input type.

impl Copy for SliderValue
