There
are two types of functions you can use in Flash; built-in functions and user-defined
functions.
|
|
|
2.
|
Built-in functions are defined by Flash and because they are local, they cannot be
called by the programmer anywhere in the script.
|
|
|
3.
|
A
function that is attached to an object is called a method.
|
|
|
4.
|
All
functions can return a value if they want to.
|
|
|
5.
|
It is
not possible to use arguments with your own user-defined functions.
|
|
|
6.
|
Function arguments are a comma-separated list of variable names which are listed in
the function definition. The arguments that are passed to the function when it is called are copied
into the variables that appear in the definition.
|
|
|
7.
|
User-defined functions can have a return value by using the keyword
return.
|
|
|
8.
|
In
Flash ActionScript, there are two types of scope; block scope and movie-clip scope.
|
|
|
9.
|
The
black plus symbol is a movie clip registration point. When you position a clip with the Info
Panel or by setting its _x and _y properties, its registration point is placed exactly at the
prescribed position.
|
|
|
10.
|
The
_visible property and the _alpha property are tied together. Changing one value affects the
other value.
|
|
|
11.
|
The
Flash authoring tool is broken down into panels.
|
|
|
12.
|
If
you want to collapse all the panels bordering one side of the document, click on the white arrow at
the edge of the group of panels to collapse the whole group.
|
|
|
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.
|
Because Flash is a vector based tool, you cannot import a rasterized graphic image
because Flash does not support bitmap graphics.
|
|
|
16.
|
The
properties panel shows porperties for a text field when one is selected.
|
|
|
17.
|
The
playhead’s position on the timeline is identified by its green color.
|
|
|
18.
|
A
keyframe is a special frame where things change on the stage.
|
|
|
19.
|
Each
layer can be locked so that any movie clip instances on it cannot be moved or deleted.
|
|
|
20.
|
The
stacking order of movie clip instances on the stage reflects the ordering of the layers in the
timeline.
|
|
|
21.
|
ActionScript is now divided into three versions: ActionScript 1.0 (AS 1.0),
ActionScript 2.0 (AS 2.0), and ActionScript 3.0 (AS 3.0).
|
|
|
22.
|
All
versions of Action Script are conveniently based on the ECMAScript standard (ECMA-262) which is a
standard based on C++ syntax.
|
|
|
23.
|
In
Flash CS3, to open the actions panel you would simply select the F8 button or Select Windows from the
Menu Bar and Select Actions.
|
|
|
24.
|
When
a lowercase A appears in a frame, it means that there is a frame label attached to that
frame.
|
|
|
25.
|
There
is no difference between a Symbol name and an Instance name in ActionScript.
|
|
|
26.
|
You
can attach script to movie clip instances.
|
|
|
27.
|
The
output panel is a tool to use while developing and testing your movie.
|
|
|
28.
|
The
key thing about variables is that they allow you to store and manipulate information.
|
|
|
29.
|
You
can name a variable anything that you want but it is advised that you create a name that makes sense
for later use.
|
|
|
30.
|
Variable names are not case sensitive in ActionScript.
|
|
|
31.
|
A
boolean variable is one that can only take one of two values: true or false.
|
|
|
32.
|
Numbers are the most common form of data to keep in a variable.
|
|
|
33.
|
With
an else Conditional only one code block will be executed.
|
|
|
34.
|
When
Flash sees a break statement in your code, it immediately leaves the current code block and begins
executing script one scope above.
|
|
|
35.
|
A for
loop is generally used when you don’t know how many times the loop needs to
iterate.
|
Multiple Choice
Identify the
letter of the choice that best completes the statement or answers the question.

|
Functions represent an important programming concept which is... a. | reliability | c. | reusability | b. | flexibility | d. | adaptability | | | | |
|
|
|
37.
|
The
organization of functions uses what are called... a. | methods | c. | properties | b. | objects | d. | all of the
above | | | | |
|
|
|
38.
|
To
execute a function that is grouped in an object, you refer to the object name, followed by the
function name, using... a. | a variable | c. | dot notation | b. | var | d. | none of the
above | | | | |
|
|
|
39.
|
The
key to using functions are.... a. | declaring the function | c. | calling the function | b. | function
arguments | d. | all of the
above | | | | |
|
|
|
40.
|
Consider the following script...
myBase = 2;
for(i = 0; i
< 10; ++i){
myResult = Math.pow(myBase,
i);
trace(“2 raised to the power “ + i +” is
“ + myResult);
}
In this example
we are calculating all the powers of 2 from.... a. | 1-10 | c. | i | b. | 0-9 | d. | both a and c | | | | |
|
|
|
41.
|
Consider the following code and indicate the most correct
answer.
function
initializeCounter(){
counter = 1;
trace(“Counter has been initialized to
1”);
}
function
incrementCounter(){
counter++;
trace(“Counter has been incremented and its value is now
“ + counter);
}
initializeCounter();
for(i = 0; i
< 5; ++i){
incrementCounter();
}
a. | This function will not work | c. | The last initializeCounter invokes both the initializeCounter
function and the incrementCounter function. | b. | Counter is equal
to 2 | d. | Each time
initializeCounter is invoked it resets counter to 1 so nothing will be added to
counter. | | | | |
|
|
|
42.
|
Consider the following code and indicate the most correct
response.
function foo(x){
x++;
trace(x);
}
myValue = 10;
foo(myValue);
trace(myValue);
a. | When function
foo(x) is called, the variable myValue is passed (copied) to argument x therefore myValue won’t
change. | c. | The myValue
variable changes when the foo function is called so the final trace function reflects this
change. | b. | myValue needs to be the argument when foo is defined and not
the value x | d. | none of the
above | | | | |
|
|
|
43.
|
Consider the following code and indicate the most correct
response.
function division(dividend,
divisor){
myResult =
dividend/divisor;
return myResult;
trace(“just did
division”);
}
myNumber = division(40,
3.6);
trace(myNumber);
a. | The return
keyword stops the function and throws you out of the code block. | c. | The “just did division” message will not
output | b. | The “just did division” message will be sent to
output | d. | both a and
c | | | | |
|
|
|
44.

way... a. | stove.kitchen.myHouse | c. | myHouse.kitchen(stove) | b. | myHouse.kitchen.stove | d. | both b and c | | | | |
|
|
