AnimationController
Deterministic animation control with every drive, repeat, and listener method.
Cloneable and timer-free: advance with tick(now) -> bool. Defaults: bounds
0..1, value at lower bound, linear curve.
| Status | Meaning |
|---|---|
Idle | Never driven (default) |
Forward / Reverse | Animating toward a bound |
Completed / Dismissed | At upper / lower bound |
Stopped | Halted mid-flight |
Driving
use incular::prelude::*;
fn main() {
let anim = AnimationController::new(std::time::Duration::from_millis(300));
let now = std::time::Instant::now();
anim.forward(now);
anim.tick(now);
println!(
"value: {}, active: {}, status: {:?}",
anim.value(),
anim.is_active(),
anim.status()
);
anim.reverse(now);
anim.reset();
}with_bounds sets custom bounds; set_value clamps; animate_to/back/drive
target values; repeat/repeat_forever loop with optional alternation.
Reading
tick (still active?), value, status, is_active, is_completed,
elapsed, duration, bounds, curve, and listener registration
(observe / add_listener / remove_listener) — value, is_active, and
status print in the runnable program above.
[`AnimationStatus`](/docs/api/painting/animation): `Idle` (default), `Forward`, `Reverse`, `Completed`,
`Dismissed`, `Stopped`.
