Struct AnimationSystem 

pub struct AnimationSystem { /* private fields */ }

Animation system for managing widget animations.

Implementations

impl AnimationSystem

pub fn new() -> Self

Create a new animation system.

pub fn animate(&mut self, widget_id: WidgetId, animation: Animation)

Add an animation for a widget.

pub fn remove_animation( &mut self, widget_id: WidgetId, property: AnimatableProperty, )

Remove an animation for a widget.

pub fn remove_widget_animations(&mut self, widget_id: WidgetId)

Remove all animations for a widget.

pub fn get_animations(&self, widget_id: WidgetId) -> Option<&WidgetAnimations>

Get animations for a widget.

pub fn get_animations_mut( &mut self, widget_id: WidgetId, ) -> Option<&mut WidgetAnimations>

Get mutable animations for a widget.

pub fn update(&mut self, delta_time: f32)

Update all animations by delta time.

pub fn animated_values( &self, ) -> HashMap<WidgetId, HashMap<AnimatableProperty, f32>>

Get all animated widget values.

Returns a map of widget IDs to their animated property values.

pub fn clear(&mut self)

Clear all animations.

pub fn widget_count(&self) -> usize

Get the number of animated widgets.

pub fn has_active(&self) -> bool

Returns true if any animations are currently running.

pub fn tick(&mut self, delta_time: f32, ui: &mut UiCore)

Tick all animations by delta time and apply values to the UI.

This combines update() with automatic application of animated values to the UI system via update_opacity, update_translate_x/y, update_scale_x/y.

Call once per frame in the update loop:

fn update(&mut self, ctx: &mut AppCtx) {
    let dt = ctx.delta_time();
    self.animations.tick(dt, &mut self.ui);
}

pub fn tick_system(&mut self, delta_time: f32, ui: &mut UiSystem)

Tick all animations by delta time and apply values to the UI system.

Convenience method that works with UiSystem instead of UiCore.

Trait Implementations

impl Default for AnimationSystem

fn default() -> Self

Returns the “default value” for a type.
