Unity 5 - hinge joint doenst work

It seems like when I apply a hinge joint targetposition that it doesnt change -- only if change the inspector will it work. Its changing the inspector value but doesnt actually do anything to the joint, only if i manually enter the data in the inspector will it work.


JointSpringsp = hinge.spring;
sp.spring = hinge.spring.spring;
sp.targetPosition = tp;
hinge.spring = sp;

Hey guys I came up with a solution that works okay I guess at least for my needs.

Code (CSharp):

1.  
2.        //therigidbody
3. private Rigidbodym_rigidBody;
4.  
5. //theinitalrotation
6. private Quaternionm_intialRot;
7.  
8. //theinitalup
9. private Vector3 m_initalUp;
10. public void Awake()
11. {
12. m_rigidBody = gameObject.GetComponent<Rigidbody>();
13. m_intialRot = transform.rotation;
14. m_initalUp = transform.up;
15. }
16.  
17.   //we hit a ball apply a force
18.         public void OnCollisionEnter(Collision col)
19.         {
20.             if(col.gameObject.name.Contains("Player"))
21.             {
22.                 ContactPoint cp = col.contacts[0];
23.                 Vector3 newPos = Vector3.Reflect(col.transform.position, cp.normal);
24.  
25.                 Vector3 dir = newPos - col.transform.position;
26.                 col.rigidbody.AddForce( dir.normalized * hitPower * m_power ,ForceMode.Impulse);
27.             }
28.         }
29.         public void handleRotateAndPower()
30.         {
31.             if(m_rotate)
32.             {
33.                 m_speed += Time.deltaTime * rotSpeed;
34.                 m_speed = Mathf.Clamp(m_speed,minSpeed,maxSpeed);
35.            
36.                 m_power = m_speed / maxSpeed;
37.                 if(m_power<0)
38.                 {
39.                     m_power *= -1;
40.                 }
41.            
42.                 m_angle0 += Time.deltaTime * m_speed;
43.                 m_angle0 = Mathf.Clamp(m_angle0,minAngle,maxAngle);
44.            
45.             }else{
46.                 m_speed -= Time.deltaTime * rotSpeed;
47.                 m_speed = Mathf.Clamp(m_speed,minSpeed,maxSpeed);
48.                 float val = m_speed / maxSpeed;
49.                 m_power = 1.0f + (m_speed / maxSpeed);
50.                 if(val > 0)
51.                 {
52.                     m_power = 1.0f - (m_speed / maxSpeed);
53.                 }
54.                 if(m_power<0)
55.                 {
56.                     m_power *= -1;
57.                 }
58.            
59.                 m_angle0 += Time.deltaTime * m_speed;
60.                 m_angle0 = Mathf.Clamp(m_angle0,minAngle,maxAngle);
61.             }
62.        
63.  
64.         }
65.        void LateUpdate () {
66.  
67. handleRotateAndPower();
68.  
69. transform.rotation = Quaternion.AngleAxis(m_angle0, m_initalUp);
70. }
