Displaying the achievements on screen
Just as we did with the stats, we will have a new menu for achievements. First, we'll
start by adding a couple of variables:
public bool showAchievements = false;
public Rect achRect = new Rect(Screen.width / 2,
Screen.height / 2, 700, 700);
Adding the GUI functions
Now, we will add the functions to show the achievements on the screen. The first func-
tion is the
OnGUI
function, which we will add now:
void OnGUI()
{
if(showAchievements)
{
achRect = GUI.Window(0, achRect, AchGUI,
"Achievements");
}
}
Just as in the stats menu, we check whether we want to show the achievements
menu. If we do it, is shown on screen; if not, we hide it.
Next, we will add the
AchGUI
function that is being called in the
OnGUI
function. This
is a large function, but it will allow us to show the achievements that we need. It is
similar to the stat menu, except we will show buttons instead of a number. We use
buttons just as a proof of concept; normally, you would use an image for your achieve-
ments.
What this function will do is use a switch statement to check the level of each achieve-
ment that we track. Then, it will show the number of achievement buttons onscreen
according to what level the player is at, within that achievement. Let's add the new
function now:
