Indicate whether the sentence or statement is true
or false.

1.
|
Built-in functions are defined by Flash and because they are local, they cannot be
called by the programmer anywhere in the script.
|
|
|
2.
|
It is
not possible to use arguments with your own user-defined functions.
|
|
|
3.
|
User-defined functions can have a return value by using the keyword
return.
|
|
|
4.
|
In
Flash ActionScript, there are two types of scope; block scope and movie-clip scope.
|
|
|
5.
|
Dynamically instantiated movie clips are the basis for deciding at run-time if we need
to add new clips to the stage.
|
|
|
6.
|
The
clip to which the function is attached defines the scope of a function.
|
|
|
7.
|
An
array is simply a block of variables.
|
|
|
8.
|
The
speed of the computer has no effect on the game experience because slower computers play Flash movies
at slower rates
|
|
|
9.
|
The’ setInterval function is not global and is not called on a
reference
|
|
|
10.
|
The
entire setBubble function is basically one big switch statement because it is the cleanest solution
to implement a state machine where each state follows the previous one without backtracking or
skipping ahead.
|
|
|
11.
|
The
playIntro function’s only purpose is to check the game state and either send lester on his
current route or choose a new route for him
|
|
|
12.
|
Changes to the actual frame rate of the game should have little or no effect on the
speed at which things move in our games.
|
|
|
13.
|
One
way to create a new object in Flash is to insert a new symbol. Doing this creates a new movie
clip that is added to your library.
|
|
|
14.
|
To
open the library panel, you can use the shortcut keys “ALT + L”
|
|
|
15.
|
The
poperties panel shows porperties for a text field when one is selected.
|
|
|
16.
|
The
playhead’s position on the timeline is identified by its green color.
|
|
|
17.
|
A
keyframe is a special frame where things change on the stage.
|
|
|
18.
|
ActionScript is now divided into two versions: ActionScript 1.0 (AS 1.0) and
ActionScript 2.0 (AS 2.0).
|
|
|
19.
|
Both
versions of Action Script are conveniently based on the ECMAScript standard (ECMA-262) which is a
standard based on C++ syntax.
|
|
|
20.
|
When
Flash sees a break statement in your code, it immediately leaves the current code block and begins
executing script one scope above.
|
Multiple Choice
Identify the
letter of the choice that best completes the statement or answers the question.

|
|
22.
|
Considering the following syntax...
