JointDrive.positionSpring

Description

Strength of a rubber-band pull toward the defined direction. Only used if mode includes Position.

    // Create a JointDrive, configure it and assign the JointDrive to
    // the zDrive element of a configurable joint.

    function Start() {
        var joint : ConfigurableJoint = gameObject.AddComponent.<ConfigurableJoint>();
        joint.targetPosition = Vector3(0,0,-10);

        var drive : JointDrive = JointDrive();
        drive.mode = JointDriveMode.Position;
        drive.positionSpring = 20;

        joint.zDrive = drive;
    }
