Timing configuration for preset animations.

Fields

delay: f64

Delay before animation starts (seconds).

duration: f64

Animation duration (seconds).

repeat: bool

Loop the animation continuously. Kept as a plain bool for source compatibility with every reader that only ever checked this flag (several live outside this workstream’s owned files) — true covers both “loop forever” (repeat_count: None) and “loop a known number of times” (repeat_count: Some(n)), so a finite count is never mistaken for a one-shot animation by code that only reads this field. The JSON "loop" key this deserializes from accepts either shape (see [AnimationTimingWire]); repeat alone can’t tell you which one was written — check repeat_count for that.

repeat_count: Option<u32>

How many times the animation plays, when the JSON "loop" value was a positive integer rather than a bare bool (issue #330) — e.g. "loop": 12 for GSAP’s repeat: 11 (11 replays, 12 plays total — this field counts total plays, not replays). None defers entirely to repeat: true loops forever, false plays once — today’s behaviour, unchanged. 0 and 1 both fold back into repeat: false, repeat_count: None at parse time (see [RepeatSpec::into_parts]): there is no visible difference between “play once” and “loop zero times”, so there’s no reason to carry a count that never changes anything downstream.

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. Works on any animation this timing drives, 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 for the preset’s motion keyframes (translate/scale/ rotate — opacity keeps its ease to avoid alpha overshoot flashes). bounce_in / elastic_in use their built-in springs as defaults; this overrides them.

amplitude: Option<f64>

Travel of an oscillating preset, in pixels (float_3d only; default 12). Threaded through to_preset_config into PresetConfig::amplitude, which expand_preset_inner already reads — this field is what makes an author-supplied amplitude actually reach it instead of the hardcoded default on every element.
