Expand description

Distance joint definition Connects a point on body A with a point on body B by a segment. Useful for ropes and springs. @ingroup distance_joint

Fields§

§base: b2JointDef

Base joint definition

§length: f32

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

§enableSpring: bool

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

§lowerSpringForce: f32

The lower spring force controls how much tension it can sustain

§upperSpringForce: f32

The upper spring force controls how much compression it an sustain

§hertz: f32

The spring linear stiffness Hertz, cycles per second

§dampingRatio: f32

The spring linear damping ratio, non-dimensional

§enableLimit: bool

Enable/disable the joint limit

§minLength: f32

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

§maxLength: f32

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

§enableMotor: bool

Enable/disable the joint motor

§maxMotorForce: f32

The maximum motor force, usually in newtons

§motorSpeed: f32

The desired motor speed, usually in meters per second

§internalValue: c_int

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