Struct AnimationStack 

pub struct AnimationStack {
    pub layers: Vec<Layer>,
    /* private fields */
}

Graphics::AnimationState with its blend stack, newest layer first. Each play pushes a layer; the one it covers fades out over the group’s blend time, and the pose mixes them.

Fields

layers: Vec<Layer>

The layers, newest first.

Implementations

impl AnimationStack

pub fn new(clip: usize, start: i64) -> Self

One layer playing clip from start.

pub fn clip(&self) -> Option<usize>

The newest layer’s clip.

pub fn play(&mut self, group: &AnimationGroup, clip: usize, start: i64)

AnimationState::PlayAnimation. A looping clip already on top keeps its time (speed back to 1). Otherwise the top layer starts fading over the blend time from its clip to clip and the new layer goes on top; a top layer never updated is replaced instead, the one below taking the blend.

Original: Runtime 0x1801007e0.

pub fn update(&mut self, group: &AnimationGroup, dt: i64) -> Vec<usize>

AnimationState::Update with UpdateNodes: the pose at the old clocks, the oldest layer’s first and each newer one mixed over it by the older layer’s share left (Quaternion::Lerp and a linear translation); then every clock advances (only the newest fires its events), and the fading layers count down, a layer leaving once less than a tick is left. Returns the newest layer’s events.

Original: Runtime 0x1801003b0, Runtime 0x1800ff4b0.

pub fn pose(&self, group: &AnimationGroup) -> Option<Vec<Transform>>

The pose of the last update, or the newest layer’s at its clock before any update.
