Struct SequenceBuilder 

pub struct SequenceBuilder { /* private fields */ }

Builder for an AnimationSequence. Steps play in the order they are added; build rejects authoring errors.

Implementations

impl SequenceBuilder

pub fn loop_mode(self, loop_mode: SequenceLoop) -> Self

Set the loop mode (default SequenceLoop::Once).

pub fn play_frames( self, frames: impl Into<Vec<usize>>, frame_duration: f32, ) -> Self

Play an explicit frame order, holding each frame for frame_duration seconds.

pub fn play_frame_range( self, first: usize, last: usize, frame_duration: f32, ) -> Self

Play the inclusive frame range first..=last.

pub fn pause(self, duration: f32) -> Self

Hold for duration seconds.

pub fn random_pause(self, min: f32, max: f32) -> Self

Hold for a duration in [min, max] when the step is entered; floating-point rounding can reach max.

pub fn action(self, id: u32) -> Self

Queue id for the caller when playback reaches this point.

pub fn build(self) -> Result<AnimationSequence, SequenceError>

Validate and build. An empty step list, an empty PlayFrames step, and a negative or NaN duration are authoring errors, not runtime states.

Trait Implementations

impl Default for SequenceBuilder

fn default() -> Self

Returns the “default value” for a type.
