I have a database/login setup in Unity, and have this piece of code that runs when a correct password and username is entered.
However, I keep getting a NullReferenceException error midway through the login process. Here is my code:
IEnumerator sendLoginRequest(string username, string password)
{
if (isDatabaseSetup == true)
{
IEnumerator e = DatabaseControl.DCF.Login(username, password);
while (e.MoveNext())
{
yield return e.Current;
}
WWW returned = e.Current as WWW;
if (returned.text == "incorrectUser")
{
//Account with username not found in database
login_error.text = "Username not found";
part = 0; //back to login UI
}
if (returned.text == "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.instance.LogIn(username, password);
}
if (returned.text == "incorrectPass")
{
//Account with username found, but password incorrect
part = 0; //back to login UI
login_error.text = "Incorrect Password";
}
if (returned.text == "ContainsUnsupportedSymbol")
{
//One of the parameters contained a - symbol
part = 0; //back to login UI
login_error.text = "Unsupported Symbol '-'";
}
if (returned.text == "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 = "";
}
}
And here is the error message I get:
NullReferenceException: Object reference not set to an instance of an object
LoginMenu+c__Iterator0.MoveNext () (at Assets/Scripts/LoginMenu.cs:160)
The specific line it mentions (160) is this:
if (returned.text == "incorrectUser")
Any idea how to get rid of this error?
