【文章內(nèi)容簡介】 Script code allows you to add interactivity to the media elements in your document. For example, you can add code that causes a button to display a new image when the user clicks it. You can also use ActionScript to add logic to your applications. Logic enables your application to behave in different ways 7 depending on the user’s actions or other conditions. Flash includes two versions of ActionScript, each suited to an author’s specific needs. For more informat ion about writing ActionScript, see Learning ActionScript in Flash in the Help panel. Flash includes many features that make it powerful but easy to use, such as prebuilt draganddrop user interface ponents, builtin behaviors that let you easily add ActionScript to your document, and special effects that you can add to media objects. When you have finished authoring your Flash document, you publish it using the File Publish mand. This creates a pressed version of your file with the extension .swf. You can then play the SWF file in a web browser or as a standalone application using Flash Player. What you can do with Flash With the wide array of features in Flash, you can create many types of applications. The following are some examples of the kinds of applications Flash is capable of generating: Animations These include banner ads, online greeting cards, cartoons, and so on. Many other types of Flash applications include animation elements as well. Games Many games are built with Flash. Games usually bine the animation capabilities of Flash with the logic capabilities of ActionScript. User interfaces Many website designers use Flash to design user interfaces. These include simple navigation bars as well as much more plex interfaces. Flexible messaging areas These are areas in web pages that designers use for displaying information that may change over time. A flexible messaging area (FMA) on a restaurant website might display information about each day’s menu specials. Rich Inter applications These include a wide spectrum of applications that provide a rich user interface for displaying and manipulating remotely stored data over the Inter. A rich Inter application could be a calendar application, a pricefinding application, a shopping catalog, an education and testing application, or any other application that presents remote data with a graphically rich interface. 8 To build a Flash application, you will typically perform these basic steps: 1. Decide which basic tasks the application will perform. 2. Create and import media elements, such as images, video, sound, text, and so on. 3. Arrange the media elements on the Stage and in the Timeline to define when and how they appear in your application. 4. Apply special effects to media elements as you see fit. 5. Write ActionScript code to control how the media elements behave, including how the elements respond to user interactions. 6. Test your application to determine if it is working as planned and find any bugs in its construction. You should test your application throughout the creation process. 7. Publish your FLA file as a SWF file that can be displayed in a web page and played back with Flash Player. Depending on your project and your working style, you may use these steps in a different order. As you bee familiar with Flash and its workflows, you will discover a style of working that suits you b
