Struct vek::tween::Tween

pub struct Tween<T, Progress = f32> {
    pub start: T,
    pub end: T,
    pub progress: Progress,
}

A convenience structure for storing a progression from one value to another.

Fields

start: T

The value when progress gets close to 0.

end: T

The value when progress gets close to 1.

progress: Progress

Expected to be between 0 and 1.

Methods

impl<T, Progress> Tween<T, Progress>

fn new(start: T, end: T) -> Self where
    Progress: Zero, 

Creates a new Tween from start and end values, setting progress to zero.

fn with_progress(start: T, end: T, progress: Progress) -> Self

Creates a new Tween from start, end and progress values.

fn get(self) -> T where
    T: Lerp<Progress, Output = T>,
    Progress: Clamp + Zero + One, 

Gets the transition's current state, clamping progress to [0;1].

fn get_unclamped(self) -> T where
    T: Lerp<Progress, Output = T>, 

Gets the transition's current state using the progress value as-is.

fn into_range(self) -> Range<T>

Converts this into a Range, dropping the progress value.
