	spring.spring = 10;
	spring.damper = 3;
	spring.targetPosition = 70;
	hinge.spring = spring;
}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    void Start() {
        HingeJoint hinge = GetComponent<HingeJoint>();
        JointSpring spring = hinge.spring;
        spring.spring = 10;
        spring.damper = 3;
        spring.targetPosition = 70;
        hinge.spring = spring;
