Struct AnimationManager 

pub struct AnimationManager { /* private fields */ }

The keyed store of in-flight animations.

Holds only what must outlive a frame.

Implementations

impl AnimationManager

pub const fn new() -> Self

An empty manager.

pub fn len(&self) -> usize

How many animations are in flight.

pub fn is_empty(&self) -> bool

Whether anything is animating (i.e. whether a frame needs scheduling).

pub fn start_or_retarget_move( &mut self, key: AnimKey, flip: FlipTransform, mode: InterpolationMode, )

Start a move, or retarget one already in flight under this key.

pub fn start_enter( &mut self, key: AnimKey, from: (f32, f32), mode: InterpolationMode, )

Start an enter animation, unless this key is already animating.

pub fn start_exit( &mut self, key: AnimKey, to: (f32, f32), mode: InterpolationMode, )

Start an exit animation.

If an animation is already in flight, the channels retarget from their current value with velocity preserved.

pub fn get_mut(&mut self, key: AnimKey) -> Option<&mut ActiveAnim>

Mutable access to an in-flight animation.

pub fn get(&self, key: AnimKey) -> Option<&ActiveAnim>

Read the current state for a key.

pub fn iter(&self) -> impl Iterator<Item = (AnimKey, &ActiveAnim)>

Every in-flight animation with its key.

pub fn tick(&mut self, dt: f32) -> Vec<AnimKey>

Advance every animation and drop the ones that arrived.

Returns the keys that finished this tick.

pub fn cancel(&mut self, key: AnimKey) -> Option<ActiveAnim>

Drop an animation without letting it finish.
