Struct Spring 

Source 
pub struct Spring {
    pub value: f32,
    pub target: f32,
    pub velocity: f32,
    pub stiffness: f32,
    pub damping: f32,
}
Expand description

A critically-dampable spring (implicit-ish) — great for snappy UI motion.

stiffness ≈ how hard it pulls toward the target, damping ≈ how fast it settles. Step with update(dt) each frame.

Implementations§

Source§

impl Spring

Source

pub fn new(value: f32, stiffness: f32, damping: f32) -> Self

Source

pub fn ui(value: f32) -> Self

A pleasant default for UI (snappy, slightly springy).

Source

pub fn set_target(&mut self, target: f32)

Source

pub fn update(&mut self, dt: f32) -> f32

Advance by dt seconds (sub-stepped for stability).

Source

pub fn is_settled(&self) -> bool
