Wheel joint definition. Body B is a wheel that may rotate freely and slide along the local x-axis in frame A. The joint translation is zero when the local frame origins coincide in world space. (b2WheelJointDef)

Fields

base: JointDef

Base joint definition

enable_spring: bool

Enable a linear spring along the local axis

hertz: f32

Spring stiffness in Hertz

damping_ratio: f32

Spring damping ratio, non-dimensional

enable_limit: bool

Enable/disable the joint linear limit

lower_translation: f32

The lower translation limit

upper_translation: f32

The upper translation limit

enable_motor: bool

Enable/disable the joint rotational motor

max_motor_torque: f32

The maximum motor torque, typically in newton-meters

motor_speed: f32

The desired motor speed in radians per second

internal_value: i32

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