public JointSpring spring { get; set; }

Remarks

The _spring force attempts to reach the target angle. A larger value makes the spring reach the target position faster.
The _damper force dampens the angular velocity. A larger value makes the spring reach the goal slower.
The spring reaches for the _targetPosition angle in degrees relative to the rest angle. The rest angle between the bodies is always zero at the beginning of the simulation.
Modifying the spring does not automatically enable it.
Enabling the _motor overrides the spring, given the spring was enabled. If the motor is again disabled the spring will be restored.

Examples

using UnityEngine;using System.Collections;public class HingeExample : MonoBehaviour{    void Start()    {        HingeJoint hinge = GetComponent<HingeJoint>();        // Make the spring reach shoot for a 70 degree angle.        // This could be used to fire off a catapult.        JointSpring hingeSpring = hinge.spring;        hingeSpring.spring = 10;        hingeSpring.damper = 3;        hingeSpring.targetPosition = 70;        hinge.spring = hingeSpring;        hinge.useSpring = true;    }}
