HealthCounter / NSUserDefaults

added preferStatusBarHidden bool to ViewController.m

—————————————————————————————————

Changed title screen to new image.

—————————————————————————————————

Added HUD images (base image, chalice, horizontal meter, journey pack,
number base, vertical meter) to project.

—————————————————————————————————

began working on HealthCounter singleton class (increments and
decrements health # based on if questions are answered correctly or
incorrectly.
 i.e. “At this difficulty, you get 5 life for every right answer, and
-1 life for every wrong answer.” To count this, use setter methods on
sharedHealthCounter to set properties for incrementValue and
decrementValue based on the difficulty level player is playing at
(these values might be written into plist eventually?

—————————————————————————————————

Added code to initialize the user defaults database (NSUserDefaults) in
the applicationDidFinishLaunching method of app delegate class. this
will store the following items (and then some):

Difficulty level
currentHealthCount
Scholar Quest IQ
Character
sound effects level
music level
whether tutorials need to be displayed or not (will default to yes, and
will change to no once they’ve appeared in game)
knowledge cards collected

The only item currently in the plist is the initial health count. The
sharedHealthCounter uses it to initialize the starting healthCount
variable, but that’s about it. I haven’t yet added in any code to
synchronize the plist after changing this value.
