Player Movement Using Velocity C#

I have been working a while on this movement script and its been holding me back. I am new to c# but I have had experience on other languages. The only way I can move my character is with the x,y,z axis. But I ran into problems such a turning. If i have Input Vertical on the z axis and i rotate my character, he will still move on the z axis.

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class Walk : MonoBehaviour {
5.     public Vector3 input;
6.     public float maxSpeed = 10f;
7.     // Use this for initialization
8.     void Start () {
9.         animation ["Rig.001|Attack"].layer = 2;
10.         animation ["Rig.001|Walk"].layer = 1;
11.         animation ["Rig.001|Idle"].layer = 1;
12.     }
13.    
14.     // Update is called once per frame
15.     void Update () {
16.  
17.  
18.  
19.        
20.  
21.         //this is the only way i can think of how to move it.
22.         input = new Vector3 (0, 0, Input.GetAxisRaw ("Vertical"));
23.            
24.            
25.  
26.             rigidbody.velocity = (input*maxSpeed);
27.            
28.            
29.            
30.            
31.            
32.             if (Mathf.Abs (Input.GetAxisRaw ("Vertical")) > 0.1)
33.                
34.                 animation.CrossFade ("Rig.001|Walk");
35.             else
36.                 animation.CrossFade ("Rig.001|Idle");
37.            
38.            
39.             if (Input.GetButtonDown ("Fire1")) {
40.  
41.                
42.                 animation.CrossFade ("Rig.001|Attack");
43.  
44.  
45.                
46.             }
47.            
48.            
49.             print (rigidbody.velocity);
50.  
51.        
52.            
53.                
54.    
55.     }
56. }
57.  

 

I think the problem is that velocity doesn't have a relative option, so when add it to the z axis, that's in world view, not model view. You need an option that uses relative velocity, or convert.

I decided to switch to translation instead of a rigidbody for movement. It works great for what I am doing.
