Fields

delay: f64

duration: f64

repeat: bool

Loop the animation continuously. Kept as a plain bool — true covers both “loop forever” (repeat_count: None) and “loop a known number of times” (repeat_count: Some(n)) — so every reader that only ever checked this flag (there were several, outside this workstream’s owned files) keeps treating a finite repeat_count as “this loops” rather than mis-reading it as a one-shot animation.

repeat_count: Option<u32>

How many times the animation plays when AnimationTiming’s widened "loop" field named an exact integer count rather than a bare bool (issue #330). None defers entirely to repeat: true loops forever, false plays once. See AnimationTiming::{repeat, repeat_count} for where this is parsed from JSON, and engine::animator::cycle_time for how it’s played back.

yoyo: bool

Reverse direction on every other play (ping-pong) instead of snapping back to the start each cycle — GSAP calls this yoyo. Only meaningful when the animation actually repeats (repeat or repeat_count); a no-op otherwise. Applies to any looping animation, not a fixed set of presets — see engine::animator::cycle_time.

repeat_delay: f64

Pause between plays, in seconds, held at the resting value of the play that just finished before the next one starts. 0.0 (default) is a seamless loop.

overshoot: Option<f64>

Overshoot/anticipation intensity for scale_in/scale_out (0.0 = none, default 0.08 = 8%).

spring: Option<SpringConfig>

Spring physics applied to the preset’s motion keyframes (see AnimationTiming::spring).

amplitude: Option<f64>

Travel of an oscillating preset, in pixels (float_3d; default 12).

Varying it across elements in one scene is what turns a shared bob into parallax: things at different depths move by different amounts.
