Struct AnimationInfo 

pub struct AnimationInfo {
    pub rate_func: fn(f64) -> f64,
    pub start_sec: f64,
    pub duration_secs: f64,
    pub enabled: bool,
}

Info of an animation.

When AnimationInfo::enabled is false, the animation will not be evaluated.

Fields

rate_func: fn(f64) -> f64

The rate function used for evaluating, default value: linear

start_sec: f64

Start sec, default value: 0.0

duration_secs: f64

The duration seconds, default value: 1.0

enabled: bool

Is enabled, default value: true

Implementations

impl AnimationInfo

pub fn range(&self) -> Range<f64>

Get the range of the animation

pub fn range_inclusive(&self) -> RangeInclusive<f64>

Get the inclusive range of the animation

pub fn map_alpha(&self, alpha: f64) -> f64

Map the outer alpha to inner alpha

pub fn map_sec_to_alpha(&self, sec: f64) -> Option<f64>

Map the global sec to outer alpha

note that this uses a range_inclusive

pub fn with_duration(self, secs: f64) -> Self

A builder func to modify AnimationInfo::duration_secs

pub fn with_enabled(self, enabled: bool) -> Self

A builder func to modify AnimationInfo::enabled
