How To: Scene Change After Facebook Login?

After Device Authentication and initializing with Gamesparks through the Splash Screen, my next scene has Facebook Login and Custom Login. I managed to make login through Facebook work but I have no idea how to implement a scene change upon completion. I tried using SceneManager.LoadLevel ( ) but I don’t know how to tie it in to only activate after Facebook Login is successful. Just leaving it as is changes the scene even if I hit “Send Cancel” when asked for the Facebook Token.

So my question is, is it possible to trigger a scene change after the script successfully completes?

Here is the code for my Facebook Login:

using UnityEngine;
using UnityEngine.UI;
using System.Collections;
using System.Collections.Generic;
using System;
using GameSparks.Core;
using GameSparks.Api;
using GameSparks.Api.Responses;
using GameSparks.Api.Requests;
using Facebook;
using Facebook.Unity;


public class FacebookScript : MonoBehaviour
{



    void Awake()
    {
        FB.Init(SetInit, OnHideUnity);
    }

    void SetInit()
    {

        if (FB.IsLoggedIn)
        {  GSFacebookLogin(AfterFBLogin);
            Debug.Log("FB is logged in");
        }
        
        else
        {
            Debug.Log("FB is not logged in");
        }

    }

    void OnHideUnity(bool isGameShown)
    {

        if (!isGameShown)
        {
            Time.timeScale = 0;
        }
        else
        {
            Time.timeScale = 1;
        }

    }

    public void FBlogin()
    {

        List<string> permissions = new List<string>();
        permissions.Add("public_profile");
        permissions.Add("user_friends");

        FB.LogInWithReadPermissions(permissions, AuthCallBack);
    }

    void AuthCallBack(IResult result)
    {

        if (result.Error != null)
        {
            Debug.Log(result.Error);
        }
        else
        {
            if (FB.IsLoggedIn)
            {
                Debug.Log("FB is logged in");
            }
            else
            {
                Debug.Log("FB is not logged in");
            }
        }

    }
    void GameSparksFBConnect(ILoginResult result)
    {

        if (FB.IsLoggedIn)
        {
            Debug.Log("Logging into gamesparks with facebook details");
            GSFacebookLogin(AfterFBLogin);
        }
        else
        {
            Debug.Log("Something wrong  with FB");
        }
    }

    //this is the callback that happens when gamesparks has been connected with FB
    private void AfterFBLogin(GameSparks.Api.Responses.AuthenticationResponse _resp)
    {
        Debug.Log(_resp.DisplayName);
    }

    //delegate for asynchronous callbacks
    public delegate void FacebookLoginCallback(AuthenticationResponse _resp);


    //This method will connect GS with FB
    public void GSFacebookLogin(FacebookLoginCallback _fbLoginCallback)
    {
        Debug.Log("");

        new GameSparks.Api.Requests.FacebookConnectRequest()
            .SetAccessToken(AccessToken.CurrentAccessToken.TokenString)
            .Send((response) =>
            {
                if (!response.HasErrors)
                {
                    Debug.Log("Logged into gamesparks with facebook");
                    _fbLoginCallback(response);
                }
                else
                {
                    Debug.Log("Error Logging into facebook");
                }

            });
    }

    
}

Just Add This to your Script.

 private void OnPlayfabFacebookAuthComplete(LoginResult result)
    {
        // SetMessage("PlayFab Facebook Auth Complete. Session ticket: " + result.SessionTicket);
       
        SceneManager.LoadScene("Main Menu");
    }
