Struct Animation 

pub struct Animation {}

Factory for the built-in node animations.

See the module docs for the difference between the event-driven and persistent families.

Implementations

impl Animation

pub fn pulse( painter: &Painter, center: Pos2, zoom: f32, initial_time: Instant, color: Color32, ) -> bool

One frame of an expanding, fading disc centred on center.

Reads as “one thing happened here”. Plays for PULSE_DURATION. Returns true while still playing.

pub fn ripple( painter: &Painter, center: Pos2, zoom: f32, initial_time: Instant, color: Color32, ) -> bool

One frame of three staggered expanding rings.

Where Animation::pulse reads as a single event, the repetition here reads as “activity is ongoing”. Plays for RIPPLE_DURATION. Returns true while still playing.

pub fn countdown_arc( painter: &Painter, center: Pos2, zoom: f32, initial_time: Instant, color: Color32, ) -> bool

One frame of a ring that empties clockwise from 12 o’clock.

The remaining arc is the remaining fraction of COUNTDOWN_DURATION, which makes it a natural fit for “how old is this information”. Returns true while still playing.

pub fn scale_in( painter: &Painter, center: Pos2, zoom: f32, initial_time: Instant, color: Color32, ) -> bool

One frame of a disc that grows past its final size and settles back.

Meant for nodes that just appeared. Plays for SCALE_IN_DURATION. Returns true while still playing.

pub fn crosshair( painter: &Painter, center: Pos2, zoom: f32, initial_time: Instant, color: Color32, ) -> bool

One frame of four ticks converging onto the node.

Reads as “target acquired”; pairs well with selection. Plays for CROSSHAIR_DURATION. Returns true while still playing.

pub fn halo( painter: &Painter, center: Pos2, zoom: f32, time: f32, color: Color32, )

One frame of a ring whose opacity breathes in and out.

For lasting state — “you are here”, “this system is camped”. time is the frame time in seconds (ui.input(|i| i.time)).

The radius has a floor in screen pixels so the halo does not vanish when the map is zoomed far out.

pub fn blink( painter: &Painter, center: Pos2, zoom: f32, time: f32, color: Color32, )

One frame of a thick ring blinking on and off.

This is the effect markers have always used, factored out of the widget so it can be selected and reused like any other. time is the frame time in seconds.

pub fn orbit( painter: &Painter, center: Pos2, zoom: f32, time: f32, color: Color32, )

One frame of a dot orbiting the node, with a faint guide ring.

Reads as “under observation”. time is the frame time in seconds.
