[Space Shooter] Problem With The PlayerController Script

Hi everyone, I'm new to Unity and I have a problem with the script of my PlayerController. Here it is :

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class PlayerController : MonoBehaviour {
5.  
6.     void FixedUpdated () {
7.         float moveHorizontal = Input.GetAxis ("Horizontal");
8.         float moveVertical = Input.GetAxis ("Vertical");
9.  
10.         Vector3 movement = new Vector3 ( moveHorizontal, 0.0f, moveVertical);
11.         Rigidbody rigidbody = GetComponent<Rigidbody>();
12.         rigidbody.velocity = movement;
13.  
14.     }
15.  
16. }

There is no error displayed in the console but when I click on the Button: Play, absolutely nothing happens, I can not move my character. Help me please

For information : I code with C# and i am using the 5.6 unity version

 

FixedUpdate not FixedUpdated

 

Debug.Log would have likely exposed the issue...
