Hi,

its a bit unclear on how to use the DeviceAuthorizationRequest.

I'm using the following Coding in Start()

 

new DeviceAuthenticationRequest()
        .Send((response) =>
        {
            string authToken = response.AuthToken;
            string displayName = response.DisplayName;
            bool? newPlayer = response.NewPlayer;
            GSData scriptData = response.ScriptData;
            var switchSummary = response.SwitchSummary;
            string userId = response.UserId;
        });

 However, I'm getting the following error message, marking the line "new DeviceAuthenticationRequest()"

NullReferenceException: Object reference not set to an instance of an object
GameSparks.Api.Requests.DeviceAuthenticationRequest..ctor ()

 What am I doing wrong?

Hi, thanks for your response.

Maybe I'm missing the point of the DeviceAuthenticationRequest, but I want to use GS in a Unity WebApp. My understnading is that I can use it there.
I did setup everything according to doc you linked. I have set the Gamesparks settings file and created my own Gamesparksmanager

 

public class FD_Gamesparksmanager : MonoBehaviour
{
    private static FD_Gamesparksmanager instance = null;
    void Awake()
    {
        if (instance == null) // check to see if the instance has a reference
        {
            instance = this; // if not, give it a reference to this class...
            DontDestroyOnLoad(this.gameObject); // and make this object persistent as we load new scenes
        }
        else // if we already have a reference then remove the extra manager from the scene
        {
            Destroy(this.gameObject);
        }
    }

    // Use this for initialization
    void Start()
    {
        authenticate();
    }

    void authenticate()
    {
        new GameSparks.Api.Requests.DeviceAuthenticationRequest()
            .SetDisplayName("Randy2")
            .Send((response) =>
            {
                if (!response.HasErrors)
                {
                    Debug.Log("Device Authenticated...");//

                }
                else
                {
                    Debug.Log("Error Authenticating Device...");
                }
            });
        }

}

 

public class FD_Gamesparksmanager : MonoBehaviour
{
    private static FD_Gamesparksmanager instance = null;
    void Awake()
    {
        if (instance == null) // check to see if the instance has a reference
        {
            instance = this; // if not, give it a reference to this class...
            DontDestroyOnLoad(this.gameObject); // and make this object persistent as we load new scenes
        }
        else // if we already have a reference then remove the extra manager from the scene
        {
            Destroy(this.gameObject);
        }
    }

    // Use this for initialization
    void Start()
    {
        authenticate();
    }

    void authenticate()
    {
        new GameSparks.Api.Requests.DeviceAuthenticationRequest()
            .SetDisplayName("Randy2")
            .Send((response) =>
            {
                if (!response.HasErrors)
                {
                    Debug.Log("Device Authenticated...");//

                }
                else
                {
                    Debug.Log("Error Authenticating Device...");
                }
            });
        }

}

 

Still getting this error:

NullReferenceException: Object reference not set to an instance of an object
GameSparks.Api.Requests.DeviceAuthenticationRequest..ctor ()
FD_Gamesparksmanager.authenticate () (at Assets/FD_Gamesparksmanager.cs:44)
FD_Gamesparksmanager.Start () (at Assets/FD_Gamesparksmanager.cs:28)

When using the registrationrequest from the example, everything works fine!

 

I just found the solution.

Seems that I can't put the DeviceAuthenticationRequest in Start().

I invoked the authenticate Method 2 seconds and authentication works now.

This is not very nice but I can workaround this. But it does seem like a bug to me
