Struct GraphCursor 

pub struct GraphCursor {
    pub state: usize,
    pub clock: f32,
    pub fade: Option<StateFade>,
}

The live position in a graph: current state, its clock, and any in-flight crossfade. One per graph target, owned by the client’s AnimationSystem.

Clock units depend on the state’s play: seconds (scaled by rate) for single clips and non-sync blendspaces, normalized phase (one full pass of the blend = 1.0) for phase-synced blendspaces, where member clips of different lengths must share one wrap point.

Fields

state: usize

The state the cursor is in.

clock: f32

The state’s clock, in the units its play uses.

fade: Option<StateFade>

The in-flight crossfade, when one is running.

Implementations

impl GraphCursor

pub fn start(graph: &CompiledGraph) -> GraphCursor

A cursor parked at the graph’s initial state.

pub fn advance(&mut self, graph: &CompiledGraph, params: &[f32], dt_secs: f32)

Advance clocks by dt_secs and take at most one transition. Transition checks run against the current state’s outgoing list in declaration order; the first whose exit-time gate and conditions all pass wins. Taking a transition while a fade is in flight replaces the fade: the new fade blends from the interrupted fade’s incoming state only, so a rapid double transition can pop the older outgoing pose.

Trait Implementations
