Adding Score Keeping
Later in the chapter I will cover Game Center. But first you need to have a
scoring system. You will make it very simple. Every time a blue brick is
destroyed, one point will be added to the score. And every time a red brick is
destroyed, you will add two points to the score. To follow the project from this
point, open the file named BreakaWall-partII-step2.gameproj .
A game attribute of type Integer will be used to keep up with the score. You will
ensure a manual reset every time you start the game. And you will increment the
score every time a brick is hit. Last but not least, you will display the score on
the top right zone of the screen, so the player can keep up with his/her
progress.
First, let's create the score attribute. Create a new game attribute of type Integer
and name it ''Score.'' Keep the default value to zero.
