Unity and Facebook SDK managing Score System

Hello!

I’ve been reading allot about this and there is very few information on this subject.

I am having trouble managing unity and facebook sdk with the score system.

So, I might be making some mistakes and I hope someone can help me through them.

So, when I open my game, I can either already be connected, or need to press the conenct button.

And this is the code I have so far.

The problem here is that I get an error when trying to POST a score = to 0.

using UnityEngine;
using System.Collections;
using System.Collections.Generic;
using Facebook.MiniJSON;
 
public class FacebookInit : MonoBehaviour {
 
    // Use this for initialization
    void Start () {
        FB.Init(OnInitComplete);
    }
 
    private void OnInitComplete()
    {
        if (FB.IsLoggedIn)
        {
            FB.API("/"+FB.UserId+"/scores", Facebook.HttpMethod.GET, retrieveScore);
            gameObject.SetActive(false);
        }
        else {
            gameObject.GetComponent<UILabel>().text = "Connect With Facebook!";
        }
    }
 
    void retrieveScore(FBResult result)
    {
        Dictionary<string, object> playerScore = Json.Deserialize(result.Text) as Dictionary<string, object>;
 
        object score;
        if (playerScore.TryGetValue("score", out score))
        {
            Debug.Log(score);
        }
        else
        {
            // Player has no score registered, so lets make it 0? Is this right?
            var wwwForm = new WWWForm();
            wwwForm.AddField("score", "0");
            FB.API("/" + FB.UserId + "/scores", Facebook.HttpMethod.POST, Callback, wwwForm);
        }
    }
 
    void Callback(FBResult result)
    {
        Debug.Log(result.Error);
    }
 
    public void CallFBLogin()
    {
        FB.Login("email,publish_actions", LoginCallback);
    }
 
    void LoginCallback(FBResult result)
    {
        if (result.Error != null){
 
            Debug.Log("Error Response:\n" + result.Error);
        }
        else if (!FB.IsLoggedIn)
        {
            Debug.Log("Login cancelled by Player");
        }
        else
        {
            Debug.Log("Login was successful!");
            FB.API("/" + FB.UserId + "/scores", Facebook.HttpMethod.GET, retrieveScore);
            gameObject.SetActive(false);
 
        }
    }
}

Did you solve that?
