pub fn start( &mut self, component: ComponentInstancePath, source: MotionSource, now: Instant, ) -> Result<MotionKey, MotionError>

Start or retarget a keyed animation at the sampled current value.

Errors

Returns MotionError for non-finite values or invalid spring parameters.

pub fn start_with_replay( &mut self, component: ComponentInstancePath, declaration: MotionSource, replay_key: Option<String>, now: Instant, ) -> Result<MotionKey, MotionError>

Errors

Returns an invalid timeline error before changing the active registry.

pub fn play_timeline( &mut self, handle: &MotionHandle, now: Instant, ) -> Result<(), MotionError>

Resume or begin a timeline.

Errors

Returns MotionError::UnknownTimeline for a stale handle.

pub fn pause_timeline( &mut self, handle: &MotionHandle, now: Instant, ) -> Result<(), MotionError>

Pause a timeline at its current deterministic clock position.

Errors

Returns MotionError::UnknownTimeline for a stale handle.

pub fn seek_timeline( &mut self, handle: &MotionHandle, position_ms: u64, now: Instant, ) -> Result<(), MotionError>

Seek to an absolute timeline position in milliseconds.

Errors

Returns a stale-handle or invalid-position error.

pub fn restart_timeline( &mut self, handle: &MotionHandle, now: Instant, ) -> Result<(), MotionError>

Restart a timeline from zero and enter the playing state.

Errors

Returns MotionError::UnknownTimeline for a stale handle.

pub fn cancel_timeline( &mut self, handle: &MotionHandle, ) -> Result<(), MotionError>

Cancel a timeline and enqueue one post-frame cancellation event.

Errors

Returns MotionError::UnknownTimeline for a stale handle.

Errors

Returns an explicit error for missing or duplicate names.
