Xbox controller buttons not working ?

I'm trying to use xbox controller in my game. the left and right analogues running but buttons not working. here is my code:

Code (CSharp):

1. using UnityEngine;
2. using System.Collections;
3.  
4. public class MOVEMENT : MonoBehaviour
5. {
6.     private Rigidbody rb;
7.  
8.     void Start()
9.     {
10.               rb = GetComponent<Rigidbody>();
11.     }
12.  
13.     void Update()
14.     {
15.         if (Input.GetKey(KeyCode.J))  {
16.                 rb.AddForce(Vector2.up * 20);
17.             }
18.  
19.         if( Input.GetButton("Xbox-X"))  {
20.                 rb.AddForce(Vector2.up * 20);
21.                 Debug.Log("xbox X");
22.            }
23.  
24.     }
25.     }

 

you've created a virtual button name, but it's not got anything assigned to it...
have a look at
http://wiki.unity3d.com/index.php?title=Xbox360Controller

for the button mappings

 

Thank you for you reply.
OK. now it's work except D-pad ? I don't know way. It's button.

 

dpad is dependent on your target platform... are you going for mac (it's a button)? windows (it's an axis)? type needs to be set appropriately

 

for me on dpad even if i set it on the axis it still doesnt read it, same for my right trigger i set on Fire 1, and both of them should be being read.
