Distance joint definition. Connects a point on body A with a point on body B by a segment. Useful for ropes and springs. (b2DistanceJointDef)

Fields

base: JointDef

Base joint definition

length: f32

The rest length of this joint. Clamped to a stable minimum value.

enable_spring: bool

Enable the distance constraint to behave like a spring. If false then the distance joint will be rigid, overriding the limit and motor.

lower_spring_force: f32

The lower spring force controls how much tension it can sustain

upper_spring_force: f32

The upper spring force controls how much compression it an sustain

hertz: f32

The spring linear stiffness Hertz, cycles per second

damping_ratio: f32

The spring linear damping ratio, non-dimensional

enable_limit: bool

Enable/disable the joint limit

min_length: f32

Minimum length for limit. Clamped to a stable minimum value.

max_length: f32

Maximum length for limit. Must be greater than or equal to the minimum length.

enable_motor: bool

Enable/disable the joint motor

max_motor_force: f32

The maximum motor force, usually in newtons

motor_speed: f32

The desired motor speed, usually in meters per second

internal_value: i32

Used internally to detect a valid definition. DO NOT SET.

Trait Implementations

impl Clone for DistanceJointDef

fn clone(&self) -> DistanceJointDef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for DistanceJointDef

impl Debug for DistanceJointDef

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

Formats the value using the given formatter.

impl Default for DistanceJointDef

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for DistanceJointDef

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