Struct skspringrs::DampedSpringController

pub struct DampedSpringController<F> { /* fields omitted */ }

Caches coefficients so that multiple springs with the same parameters may be used without re-running trigonometry calls.

Methods

impl<F> DampedSpringController<F> where     F: Float + FromPrimitive,

pub fn with_coefficients(     delta_time: F,     desired_angular_frequency: F,     desired_damping_ratio: F ) -> DampedSpringController<F>

Performs (somewhat nontrivial) calculations to prepare the motion of a damped spring. Once initialized, you may update any spring with identical properties with update using the same object.

pub fn update(&self, position: &mut F, velocity: &mut F, target: F)

Updates the position and velocity of a spring using this controller's physical properties.
