78 Chapter 3: Writing and Debugging Scripts
Listing a SWF file’s variables
In test mode, the List Variables command displays a list of all the variables currently in the SWF
file. This is especially useful for finding the correct variable target path and variable name. Unlike
the Debugger, the list does not update automatically as the SWF file plays; you must select the
List Variables command each time you want to send the information to the Output panel.
The List Variables command also displays global variables declared with the
_global identifier.
The global variables are displayed at the top of the List Variables output in a “Global Variables”
section, and each variable is prefixed with
_global.
In addition, the List Variables command displays getter/setter properties—properties that are
created with the
Object.addProperty() method and invoke get or set methods. A getter/
setter property is displayed alongside any other properties in the object it belongs to. To make
these properties easily distinguishable from ordinary variables, the value of a getter/setter property
is prefixed with the string
[getter/setter]. The value displayed for a getter/setter property is
determined by evaluating the
get function of the property.
To display a list of variables in a SWF file:
1 If your SWF file is not running in test mode, select Control > Test Movie.
2 Select Debug > List Variables.
A list of all the variables currently in the SWF file is displayed in the Output panel, as shown in
this example:
Global Variables:
Variable _global.MyGlobalArray = [object #1] [
0:1,
1:2,
2:3
]
Level #0:
Variable _level0.$version = "WIN 6,0,0,101"
Variable _level0.RegularVariable = "Gary"
Variable _level0.AnObject = [object #1] {
MyProperty: [getter/setter] 3.14159
}
Displaying text field properties for debugging
To get debugging information about TextField objects, you can use the Debug > List Variables
command in test movie mode. The Output panel uses the following conventions in displaying
TextField objects:
• If a property is not found on the object, it is not displayed.
• No more than four properties are displayed on a line.
• A property with a string value is displayed on a separate line.
• If there are any other properties defined for the object after the built-in properties are
processed, they are added to the display using the rules in the second and third points above.
• Color properties are displayed as hexadecimal numbers (0x00FF00).
• The properties are displayed in the following order: variable, text, htmlText, html,
textWidth, textHeight, maxChars, borderColor, backgroundColor, textColor, border,
background, wordWrap, password, multiline, selectable, scroll, hscroll, maxscroll,
maxhscroll, bottomScroll, type, embedFonts, restrict, length, tabIndex, autoSize.
