Question by Shabby91 · Apr 27, 2017 at 04:55 PM · multiplayerfpsdatabase

MultiplayerFPS - database error

With the new updates of the free database assets appared this error that i can’t risolve:

NullReferenceException: Object reference not set to an instance of an object LoginMenu+c__Iterator0.MoveNext () (at Assets/LoginMenu.cs:146) UnityEngine.SetupCoroutine.InvokeMoveNext (IEnumerator enumerator, IntPtr returnValueAddress) (at C:/buildslave/unity/build/Runtime/Export/Coroutines.cs:17)

That refers to:

WWW returned = e.Current as WWW; if (returned.text == "Success") {

Any suggestion ?

IEnumerator sendLoginRequest(string username, string password) {

     if (isDatabaseSetup == true)
     {

         IEnumerator e = DCF.Login(username, password);
         while (e.MoveNext())
         {
             yield return e.Current;
         }
         string returned = e.Current as string;
         if (returned == "Success")
         {

             //Password was correct
             blankErrors();
             part = 2; //show logged in UI

             //blank username field
             input_login_username.text = ""; //password field is blanked at the end of this function, even when error is returned
                                             //UserAccountManager.LoggedIn_Username = username;
                                             // UserAccountManager.LoggedIn_Password = password;

             UserAccountManager.instance.LogIn(username, password);
         }
         if (returned == "incorrectUser")
         {
             //Account with username not found in database
             login_error.text = "Username not found";
             part = 0; //back to login UI
         }
         if (returned == "incorrectPass")
         {
             //Account with username found, but password incorrect
             part = 0; //back to login UI
             login_error.text = "Incorrect Password";
         }
         if (returned == "ContainsUnsupportedSymbol")
         {
             //One of the parameters contained a - symbol
             part = 0; //back to login UI
             login_error.text = "Unsupported Symbol '-'";
         }
         if (returned == "Error")
         {
             //Account Not Created, another error occurred
             part = 0; //back to login UI
             login_error.text = "Database Error. Try again later.";
         }

         //blank password field
         input_login_password.text = "";

     }
 }
