Did you try Parsing directly the input value to INT?

Hi There,
I have figured out how to Parse the string value in an integer that will be stored in “int level” variable.
Maybe it is an overkill but I think it is well worth trying it.

     void OnUserInput(string input)
        {
            if (input == "1"|| input == "2" || input == "3")
            {
                level = System.Int32.Parse(input);
                StartGame();
            }
            else
            {
                print("bad value");
                ShowMainMenu();
            }

        }

Hi,

Take a look at TryParse also, this can give you the conversion but also a return value to indicate whether the parse was successful or not, so, if you had made a mistake an let a word through, for example, it would return false which you could then use in validation. Parse will give the conversion if it can, but throw an exception if it can’t.
