Struct SpringJointBehaviour 

pub struct SpringJointBehaviour { /* private fields */ }

A joint behaviour that will move the anchored body into a position and angle relative to the anchor over time.

Implementations

impl SpringJointBehaviour

pub fn new(rigidness: f32) -> Option<SpringJointBehaviour>

Create a new SpringJointBehaviour with an exact rigidness value.

Rigidness describes how “snappy” the spring joint is. When it’s at 0.0, the anchored body will “jump” into position softly over one second. When it’s at 1.0, the anchored body will “jump” into position almost instantaenously.

impl JointBehaviour for SpringJointBehaviour

const STAGE: &'static str = stage::COLLIDING_JOINT

fn linear_velocity( &mut self, _offset: Vec2, _anchor: &RigidBody, _target: &RigidBody, ) -> Option<Vec2>

Returns a new linear velocity for target based on self and anchor.

fn angular_velocity( &mut self, _angle: f32, _anchor: &RigidBody, _target: &RigidBody, ) -> Option<f32>

Returns a new angular velocity for target based on self and anchor.

fn linear_impulse( &mut self, offset: Vec2, anchor: &RigidBody, target: &RigidBody, ) -> Option<Vec2>

Returns a linear impulse to apply to target based on self and anchor.

fn angular_impulse( &mut self, angle: f32, anchor: &RigidBody, target: &RigidBody, ) -> Option<f32>

Returns an angular impulse to apply to target based on self and anchor.

fn position( &mut self, _offset: Vec2, _anchor: &RigidBody, _target: &RigidBody, ) -> Option<Vec2>

Returns a new position for target based on self and anchor.

fn rotation( &mut self, _angle: f32, _anchor: &RigidBody, _target: &RigidBody, ) -> Option<f32>

Returns a new rotation for target based on self and anchor.

impl PartialEq for SpringJointBehaviour

fn eq(&self, other: &SpringJointBehaviour) -> 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.
