Using behaviors consistently

Use behaviors consistently throughout a document when they are your main or only source of ActionScript. Use

behaviors when you have little or no additional code in the FLA file, or have a consistent system in place for

managing the behaviors that you use.

IfyouaddActionScripttoaFLAfile,putcodeinthesamelocationswherebehaviorsareadded,anddocumenthow

and where you add code.

For example, if you place code on instances on the Stage (object code), on the main Timeline (frame scripts), and

also in external AS files, examine your file structure. Your project will be difficult to manage if you have code in all

of these places. However, if you logically use behaviors and structure your code to work in a particular way

surrounding those behaviors (place everything on object instances), at least your workflow is consistent. The

document will be easier to modify later.

Sharing files that use behaviors

If you plan to share your FLA file with other users and you use ActionScript placed on or inside objects (such as

movie clips), it can be difficult for those users to find your code’s location, even when they use the Movie Explorer

to search through the document.

Document the use of behaviors if you are working with a complex document. Depending on the size of the appli-

cation, create a flow chart, list, or use good documentation comments in a central location on the main Timeline.

If you are creating a FLA file with code placed in many locations throughout the document and plan to share the file,

leaveacommentonFrame1onthemainTimelinetotelluserswheretofindthecodeandhowthefileisstructured.

The following example shows a comment (on Frame 1) that tells users the location of the ActionScript:

ActionScript placed on component instances and inside movie clips using behaviors.

Use the Movie Explorer to locate ActionScript

Video conventions

About video conventions

Many options are available to edit video before you import it into a FLA document, or load an FLV file into a SWF

file. Flash and Flash Video Encoder have greater controls for video compression. Compressing video carefully is

important because it controls the quality of the video footage and the size of the file. Video files, even when

compressed, are large in comparison with most other assets in your SWF file.

Note: Provide the user with control over the media in a SWF file. For example, if you add audio to a document with

video (or even a looping background sound), let the user control the sound.
