Using scenes

Using scenes is similar to using several SWF files to create a larger presentation. Each scene has a timeline. When the playhead reaches the final frame of a scene, the playhead progresses to the next scene. When you publish a SWF file, the timeline of each scene combines into a single timeline in the SWF file. After the SWF file compiles, it behaves as if you created the FLA file using one scene. Because of this behavior, avoid using scenes for the following reasons:

• Scenes can make documents confusing to edit, particularly in multiauthor environments. Anyone using the FLA document might have to search several scenes within a FLA file to locate code and assets. Consider loading content or using movie clips instead.

• Scenes often result in large SWF files.

• Scenes force users to progressively download the entire SWF file, instead of loading the assets they actually want to see or use. If you avoid scenes, the user can control what content they download as they progress through your SWF file. The user has more control over how much content they download, which is better for bandwidth management. One drawback is the requirement for managing a greater number of FLA documents.

• Scenes combined with ActionScript might produce unexpected results. Because each scene timeline is compressed onto a single timeline, you might encounter errors involving your ActionScript and scenes, which typically requires extra, complicated debugging.

  If you create lengthy animations, you might find it advantageous to use scenes. If disadvantages apply to your document, consider using multiple FLA files, or movie clips to build an animation instead of using scenes.
