I am work on a hobbyist-level game with a couple friends. The guy that does the harder coding is out of town, and I'm up the creek trying to implement a new feature.

I am trying to implement difficulty levels. I have added the combobox at the new game screen using the following (it is an airline simulation):

 lbContent.Items.Add(new QuickInfoValue(Translator.GetInstance().GetString("PageNewGame", "1011"), cbDifficulty));

            cbOpponents = new ComboBox();
            cbOpponents.SetResourceReference(ComboBox.StyleProperty, "ComboBoxTransparentStyle");
            cbOpponents.HorizontalAlignment = System.Windows.HorizontalAlignment.Left;
            cbOpponents.Width = 50;
            cbOpponents.HorizontalContentAlignment = System.Windows.HorizontalAlignment.Right;
            for (int i = 0; i < Airlines.GetAllAirlines().Count; i++)
                cbOpponents.Items.Add(i);

            cbOpponents.SelectedIndex = 3;// cbOpponents.Items.Count - 1;

        private void cbDifficulty_Selectionchanged(object sender, SelectionchangedEventArgs e)
        {

            Airline airline = (Airline)cbDifficulty.SelectedItem;
            int year = (int)cbStartYear.SelectedItem;

            setAirportsView(year, airline.Profile.Country);
        }

The combobox is displaying fine, however I am having a bit of trouble with setting the difficulty level when the Selectionchanged occurs.

This is the abbreviated code for the game object (where we set our initial settings for a new game):

public class GameObject
{
  public enum DifficultyLevel { Easy, Normal, Hard }
  public DifficultyLevel difficulty { get; set; }
private GameObject()
{
  this.difficulty = DifficultyLevel.Easy;
}

//returns the starting money
private long getStartMoney()
{
  long baseStartMoney = 125000000;
  if (difficulty == Easy)
  { baseStartMoney *= (3 / 2); }
  else if (difficulty == Normal)
  { baseStartMoney *= 1;}
  else if (difficulty == Hard)
  { baseStartMoney *= (1/2);}

  return Convert.ToInt64(GeneralHelpers.GetInflationPrice(baseStartMoney));
}

The difficulty levels are returning as not in context, but I have been staring at this screen for an hour or so and I'm running out of fresh ideas.

A gentle shove in the right direction would be greatly appreciated I'm still learning C#, so take it easy on the rookie

I suspect it's Easy, Normal and Hard that are giving the errors, you need to prefix those with the Enum name. And you should be using a case statement instead of the if/else/if.

I changed it to the following, it took care of the code errors but still not functioning in game:

  if (difficulty == DifficultyLevel.Easy)
15
  { baseStartMoney *= (3 / 2); }
16
  else if (difficulty == DifficultyLevel.Normal)
17
  { baseStartMoney *= 1;}
18
  else if (difficulty == DifficultyLevel.Hard)
19
  { baseStartMoney *= (1/2);}

I know the case statement would do it more efficiently, but shouldn't it still function using the if elseif?

You said it's still not functioning. Have you set a breakpoint in the code and stepped through it to see what is happening and giving you the expected results?

So the user changes the difficulty, but what are you doing with year?????

private void cbDifficulty_Selectionchanged(object sender, SelectionchangedEventArgs e)
{
	//What does year have to do with difficulty?
   Airline airline = (Airline)cbDifficulty.SelectedItem;
   int year = (int)cbStartYear.SelectedItem;

   setAirportsView(year, airline.Profile.Country);
}

Aren't you supposed to set the difficulty proptery of your game object instead?


In your if statements you have to tell it what enum you are looking at

//returns the starting money
private long getStartMoney()
{
	long baseStartMoney = 125000000;
	if (difficulty == DifficultyLevel.Easy)
	{ 
		baseStartMoney *= (3 / 2); 
	}
	else if (difficulty == DifficultyLevel.Normal)
	{ 
		baseStartMoney *= 1;
	}
	else if (difficulty == DifficultyLevel.Hard)
	{ 
		baseStartMoney *= (1/2);
	}

  return Convert.ToInt64(GeneralHelpers.GetInflationPrice(baseStartMoney));
}

The game also allows the user to change the start year, that was probably a straggler piece of code I forgot to edit out.

Anyway, I am glad to say I was able to resolve the issue. The problem was that it should have read:

if (GameObject.GetInstance().Difficulty == GameObject.DifficultyLevel.Hard)
{ baseStartMoney *= 0.5 }

etc

Thanks for the help guys
