Any tutorials on Tires turning with Wheel colliders (4.6)?

My tires spin perfectly the way I want them too, however I can seem to find a straightforward tutorial or free piece of code (in C#) that can help me Turn the tires in the same angle as my wheel colliders.

I would appreciate if someone could point me in the right direction! I've been searching for about 3 hours and all I can seem to find are people asking how to rotate the tires which is something I have already figured out.

 

So your tire objects control their rotation on the Z and you want to set their rotation on the Y to match the wheel collider so they turn left and right?

Should just be:

Code (csharp):

1.  
2. Quaternion tireRotation = tire.transform.rotation;
3. Quaternion colliderRotation = collider.transform.rotation;
4.  
5. tire.transform.rotation = Quaternion.Euler(tireRotation.eulerAngles.x, colliderRotation.eulerAngles.y, tireRotation.eulerAngles.z);
6.  

 

My code is as follows but I got the following error:

Assets/Scripts/HarvMovementScript.cs(17,35): error CS0236: A field initializer cannot reference the nonstatic field, method, or property `HarvMovementScript.WheelsFL'
&
Assets/Scripts/HarvMovementScript.cs(18,39): error CS0236: A field initializer cannot reference the nonstatic field, method, or property `HarvMovementScript.WheelColliderFL'

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class HarvMovementScript : MonoBehaviour {
5.  
6.     public float MotorForce;
7.     public WheelCollider WheelColliderFL;
8.     public WheelCollider WheelColliderFR;
9.     public WheelCollider WheelColliderRL;
10.     public WheelCollider WheelColliderRR;
11.     public Transform WheelsFL; // front left wheel mesh only ( no collider)
12.     public Transform WheelsFR; // front right wheel mesh only ( no collider)
13.     public Transform WheelsBL; // back left wheel mesh only ( no collider)
14.     public Transform WheelsBR; // back right wheel mesh only ( no collider)
15.     public float SteerForce;
16.     public float BrakeForce;
17.     Quaternion tireRotation = WheelsFL.transform.rotation;
18.     Quaternion colliderRotation = WheelColliderFL.transform.rotation;
19.  
20.     ///public float TurnSpeed;
21.     ///public float TurnAngle;
22.  
23.     // Use this for initialization
24.     void Start () {
25.    
26.  
27.  
28.     }
29.    
30.     // Update is called once per frame
31.     void Update () {
32.    
33.         float v = Input.GetAxis ("Vertical") * MotorForce;
34.         float h = Input.GetAxis ("Horizontal") * SteerForce;
35.        
36.  
37.         WheelColliderRL.motorTorque = v;
38.         WheelColliderFL.motorTorque = v;
39.         WheelColliderRR.motorTorque = v;
40.         WheelColliderFR.motorTorque = v;
41.  
42.         WheelColliderFL.steerAngle = h;
43.         WheelColliderFR.steerAngle = h;
44.  
45.         WheelColliderFL.transform.rotation = Quaternion.Euler(tireRotation.eulerAngles.x, colliderRotation.eulerAngles.y, tireRotation.eulerAngles.z);
46.  
47.        
48.  
49.  
50.         WheelsFL.Rotate(WheelColliderFL.rpm / 60 * 360 * Time.deltaTime,0,0);
51.         WheelsFR.Rotate(WheelColliderFR.rpm / 60 * 360 * Time.deltaTime,0,0);
52.         WheelsBL.Rotate(WheelColliderFL.rpm / 60 * 360 * Time.deltaTime,0,0);
53.         WheelsBR.Rotate(WheelColliderFR.rpm / 60 * 360 * Time.deltaTime,0,0);
54.  
55.  
56.  
57.         ///Brakeon
58.         if (Input.GetKey (KeyCode.Space)) {
59.        
60.         WheelColliderRL.brakeTorque = BrakeForce;
61.         WheelColliderRR.brakeTorque = BrakeForce;
62.         WheelColliderFL.brakeTorque = BrakeForce;
63.         WheelColliderFR.brakeTorque = BrakeForce;
64.         }
65.  
66.         ///Brakeoff
67.         if (Input.GetKeyUp (KeyCode.Space)) {
68.                         WheelColliderRL.brakeTorque = 0;
69.                         WheelColliderRR.brakeTorque = 0;
70.                         WheelColliderFL.brakeTorque = 0;
71.                         WheelColliderFR.brakeTorque = 0;
72.  
73.                 }
74.            
75.  
76.  
77.     }
78. }
79.  

 

Move these two lines:

Code (csharp):

1.  
2.   Quaternion tireRotation = WheelsFL.transform.rotation;
3.   Quaternion colliderRotation = WheelColliderFL.transform.rotation;
4.  

Down to just before this line:

Code (csharp):

1.  
2. WheelColliderFL.transform.rotation = Quaternion.Euler(tireRotation.eulerAngles.x, colliderRotation.eulerAngles.y, tireRotation.eulerAngles.z);
3.  

Quaternions are structs (value types), so you can't store references to them like you can classes (reference types).
