Menus and Settings
20.1 Introduction
In the
Jewel Jam
game, we have already seen a few basic examples of adding GUI
elements to your game such as a button or a frame. In this chapter, we are going to
add a few more GUI elements, such as an on/off button and a slider button. Secondly,
we will show how you can read and store game settings, such as music volume or
whether hints are allowed or not.
20.2 Setting up the Menu
As an example, we will show how to define a basic 'options' menu containing two
controls: one for switching hints on or off, and one for controlling the volume of the
music. First, we need to draw the elements surrounding these controls. We first add
a background to the menu. Second, we add a text label to the menu to describe the
'hints' control. We are going to use the
TextGameObject
class taken from the
Jewel
Jam
game for that. We define the text that should be drawn, and we place it at the
appropriate position:
TextGameObject onofftext =
new
TextGameObject("Fonts/MenuFont", 1);
onofftext.Text = "Hints";
onofftext.Position =
new
Vector2(150, 340);
onofftext.Color = Color.DarkBlue;
gameWorld.Add(onofftext);
Similarly, we add a text label for the music volume controller. For the complete
code, see the
PenguinPairs2
example belonging to this chapter.
