Listing 20.2 A basic class for handling game settings

protected static GameSettingsManager gameSettingsManager;
...
public static GameSettingsManager GameSettingsManager
{

get { return gameSettingsManager; }

}

We now add two methods to the manager for storing ( SetValue ) and for accessing
( GetValue ) settings. The implementation of these methods is rather straightforward,
see Listing 20.2 for the complete class.
Updating the hint setting depending on the state of the on/off button is now very
easy. We simply add these lines of code to the Update method of the PenguinPairs
class:

if (onOffButton.On)
GameSettingsManager.SetValue("hints", "on");
else
GameSettingsManager.SetValue("hints", "off");
