Expand description

A joint that removes all relative linear motion between a pair of points on two bodies.

Fields

local_anchor1: Point<Real>

Where the ball joint is attached on the first body, expressed in the first body local frame.

local_anchor2: Point<Real>

Where the ball joint is attached on the first body, expressed in the first body local frame.

impulse: Vector<Real>

The impulse applied by this joint on the first body.

The impulse applied to the second body is given by -impulse.

motor_target_vel: Vector<Real>

The target relative angular velocity the motor will attempt to reach.

motor_target_pos: Rotation<Real>

The target angular position of this joint, expressed as an axis-angle.

motor_stiffness: Real

The motor’s stiffness. See the documentation of SpringModel for more information on this parameter.

motor_damping: Real

The motor’s damping. See the documentation of SpringModel for more information on this parameter.

motor_max_impulse: Real

The maximal impulse the motor is able to deliver.

motor_impulse: Vector<Real>

The angular impulse applied by the motor.

motor_model: SpringModel

The spring-like model used by the motor to reach the target velocity and .
