You will, once again, use the Start Project option to work on; this way, you won't need to
type logic or syntax already covered in previous chapters. The Start Project option con-
tains all the resource files and all the class declarations as well as placeholders for all the
methods inside the classes' implementation files. We'll go over these in a moment.
You should run the final project version to acquaint yourself with the game. By pressing
and dragging your finger on the rocket ship, you draw a line. Release the touch and you
create a pivot point. The ship will rotate around this pivot point until you press on the ship
again to release it. Your aim is to collect the bright supernovas and avoid the planets.
