Prismatic joint definition

This requires defining a line of motion using an axis and an anchor point. The definition uses local anchor points and a local axis so that the initial configuration can violate the constraint slightly. The joint translation is zero when the local anchor points coincide in world space. @ingroup prismatic_joint

Fields§

§bodyIdA: b2BodyId

The first attached body

§bodyIdB: b2BodyId

The second attached body

§localAnchorA: b2Vec2

The local anchor point relative to bodyA’s origin

§localAnchorB: b2Vec2

The local anchor point relative to bodyB’s origin

§localAxisA: b2Vec2

The local translation unit axis in bodyA

§referenceAngle: f32

The constrained angle between the bodies: bodyB_angle - bodyA_angle

§enableSpring: bool

Enable a linear spring along the prismatic joint axis

§hertz: f32

The spring stiffness Hertz, cycles per second

§dampingRatio: f32

The spring damping ratio, non-dimensional

§enableLimit: bool

Enable/disable the joint limit

§lowerTranslation: f32

The lower translation limit

§upperTranslation: f32

The upper translation limit

§enableMotor: bool

Enable/disable the joint motor

§maxMotorForce: f32

The maximum motor force, typically in newtons

§motorSpeed: f32

The desired motor speed, typically in meters per second

§collideConnected: bool

Set this flag to true if the attached bodies should collide

§userData: *mut c_void

User data pointer

§internalValue: i32

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