A Timeline is a sequence of Acts that play in order.

Implementations

impl Timeline

pub fn new() -> Self

Create a new empty timeline.

pub fn act(self, act: Act) -> Self

Add an act to the timeline.

pub fn loop_forever(self) -> Self

Set the timeline to loop from the beginning.

pub fn loop_from(self, act_name: impl Into<String>) -> Self

Set the timeline to loop starting from a specific act.

pub fn on_loop<F: Fn(u32) + 'static>(self, callback: F) -> Self

Set a callback to fire when the timeline loops.

The callback receives the loop iteration count (1 for first loop, 2 for second, etc.).

pub fn on_act_enter<F: Fn(&str) + 'static>(self, callback: F) -> Self

Set a callback to fire when any act is entered.

The callback receives the act name.

pub fn on_act_exit<F: Fn(&str) + 'static>(self, callback: F) -> Self

Set a callback to fire when any act is exited.

The callback receives the act name.

pub fn then(self, other: Timeline) -> Self

Chain another timeline after this one.

pub fn duration(&self) -> f64

Get the total duration of the timeline (before looping).

pub fn act_count(&self) -> usize

Get the number of acts.

pub fn at(&self, time: f64) -> TimelineState<'_>

Query the timeline state at a specific time.

pub fn start(&self) -> PlayingTimeline

Create a playing timeline instance.
