Struct Spring

pub struct Spring {
    pub stiffness: f32,
    pub damping: f32,
    pub target_value: f32,
}

A spring constraint, used for both linear and angular constraints.

Fields

stiffness: f32

The stiffness (also called spring coefficient) has units of force/distance for spring_linear or force/angle in degrees for spring_angular.

damping: f32

The damping coefficient of the spring.

target_value: f32

The resting position of the spring.

Implementations

impl Spring

pub fn parse(e: &Element) -> Result<Self, Error>

Parse a Spring from a <linear> or <angular> XML element.

pub fn is_empty(&self) -> bool

Is this Spring instance set to the default value?

Trait Implementations

impl Clone for Spring

fn clone(&self) -> Spring

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Spring

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Spring

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Spring

fn eq(&self, other: &Spring) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
