private function cleanUp():void {
var circleLength:int = circles.length-1;
for (var counter:int = circleLength; counter >= 0; counter--){
removeCircle(counter);
}
var scoreTextLength:int = scoreTexts.length-1;
for (counter= scoreTextLength; counter >= 0; counter--) {
removeScoreText(counter);
}
}
} // close class
} // close package
Using the same loop optimizations you have seen a few times in this chapter, the
cleanUp
function calls the
removeCircle
function for each
Circle
instance left in the
circles
array.
As with the final function on all of our classes, the final two closing brackets (
}
) close the class
and the package respectively.
That's it for the
SuperClick
game class. Now let's move on to the two final classes for this game.
First up is the
Circle.as
class.
The Circle Class
The
Circle
class dynamically creates a circle shape. It extends the
Sprite
class, so it is
clickable using the
MouseEvent.CLICK
event.
Defining the Circle class
These are the static constants needed for the
Circle
class:
CIRCLE_GOOD
and
CIRCLE_BAD
.
The following public attributes are needed:
clicked
: This Boolean is set to
true
when the circle is clicked.
type
: This integer holds one of the two static constants:
CIRCLE_GOOD
or
CIRCLE_BAD
. This
could have simply be a Boolean using
true
for good and
false
for bad, but to make the
attribute more extensible in the future, we have used constants to define the basic types.
For example, later you might want to add a
CIRCLE_POWER_UP
constant that gives the
player extra time.
nextScale
: This attribute holds the next
scaleX
and
scaleY
value for the
Circle
. It is
updated in the internal update function that is called by the
SuperClick.update
function
and is rendered in the
render
function of the
SuperClick
class.
fadingOut
: This Boolean value set to
true
once a
CIRCLE_GOOD
is clicked by the player.
For the constructor arguments, we need a passed-in
type
value that will be one of the two
constants:
CIRCLE_GOOD
or
CIRCLE_BAD
.
