What’s New in Flash 8 ActionScript

The following features were added to both Flash Basic 8 and Flash Professional 8 (unless 
noted otherwise):

■

ActionScript editor enhancements let you show hidden characters in your scripts. For 
more information, see 

“Showing hidden characters” on page 53

.

■

Debug options are now available in the Script window, as well as the Actions panel, for 
ActionScript files.

■

The Configuration directory that includes XML files and Class files is reorganized. See 

“Configuration files that install with Flash 8” on page 65

 for details.

■

You can set a preference to reload modified script files when working on an application, 
which helps you avoid working with older versions of script files, and overwriting newer 
script files. For more information, see 

“About ActionScript preferences” on page 42

.

■

The Script window feature is available in Flash Basic 8 and Flash Professional 8. That 
means you can now create an ActionScript file in either program.

■

Script Assist (similar to Normal Mode in earlier editions of Flash) helps you code without 
needing to understand syntax. For more information on Script Assist, see 

“About Script 

Assist” on page 58

.

■

You can load new kinds of image files at runtime, which include progressive JPEG images, 
and non-animated GIF and PNG files. If you load an animated file, the first frame of the 
animation appears.

■

You can assign linkage identifiers to bitmap and sound files stored in the Library, which 
means that you can attach images to the Stage or work with these assets in shared libraries.

■

Bitmap caching lets you improve the performance of your applications at runtime by 
caching a bitmap representation of your instances. You can use ActionScript code to access 
this property. For more information, see 

“About bitmap caching, scrolling, and 

performance” on page 480

.

■

9-slice scaling lets you scale movie clip instances without widening the strokes that outline 
the movie clip. You can use ActionScript code to access this feature in Flash Basic 8 and 
Flash Professional 8, or in the Flash 8 authoring tool. For more information, see 

“Working 

with 9-slice scaling in ActionScript” on page 558

. For information about accessing 9-slice 

scaling in the authoring tool, see 

“About 9-slice scaling and movie clip symbols” 

on page 79

 in 

Using Flash

.

■

You can now add metadata information to your FLA files in the Publish Settings dialog 
box. You can add a name and description to your FLA file using the dialog box to help 
increase online search visibility. 

■

The Strings panel is improved to include multiline support in the String field and a 
language XML file. For more information, see 

“About the Strings panel” on page 452

.
