30、 enables user interaction. Flash projects can include simple animations, video content, complex presentations, applications, and everything in between. In general, individual pieces of content made with Flash are called

34、;/p><p>　　To build an application in Flash, you create graphics with the Flash drawing tools and import additional media elements into your Flash document. Next, you define how and when you want to use each of

35、those elements to create the application you have in mind. </p><p>　　When you author content in Flash, you work in a Flash document file. Flash documents have the file extension .fla. A Flash document has fo

36、ur main parts:</p><p>　　The Stage is where your graphics, video, buttons, and so on appear during playback.</p><p>　　The Timeline is where you tell Flash when you want the graphics and other ele

39、de 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 depending on the user’s

40、actions or other conditions. Flash includes two versions of ActionScript, each suited to an author’s specific needs. For more information about writing ActionScrip</p><p>　　Flash includes many features that

41、make it powerful but easy to use, such as prebuilt drag-and-drop user interface components, built-in behaviors that let you easily add ActionScript to your document, and special effects that you can add to media objects.

42、</p><p>　　When you have finished authoring your Flash document, you publish it using the File > Publish command. This creates a compressed version of your file with the extension .swf. You can then play t

43、he SWF file in a web browser or as a stand-alone application using Flash Player. </p><p>　　What you can do with Flash</p><p>　　With the wide array of features in Flash, you can create many types

44、 of applications. The following are some examples of the kinds of applications Flash is capable of generating:</p><p>　　Animations These include banner ads, online greeting cards, cartoons, and so on. M

47、t;p>　　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 informati

54、;<p>　　Publish your FLA file as a SWF file that can be displayed in a web page and played back with Flash Player. </p><p>　　Depending on your project and your working style, you may use these steps in

55、 a different order. As you become familiar with Flash and its workflows, you will discover a style of working that suits you best.</p><p>　　About ActionScript and events</p><p>　　In Macromedia F

56、lash Basic 8 and Macromedia Flash Professional 8, ActionScript code is executed when an event occurs: for example, when a movie clip is loaded, when a keyframe on the Timeline is entered, or when the user clicks a button

57、. Events can be triggered either by the user or by the system. Users click mouse buttons and press keys; the system triggers events when specific conditions are met or processes completed (the movie loads, the Timeline r

58、eaches a certain frame, a graphic finishes do</p><p>　　When an event occurs, you write an event handler to respond to the event with an action. Understanding when and where events occur will help you to dete

59、rmine how and where you will respond to the event with an action, and which ActionScript tools should be used in each case. </p><p>　　Events can be grouped into a number of categories: mouse and keyboard eve

60、nts, which occur when a user interacts with your Flash application via the mouse and keyboard; clip events, which occur within movie clips; and frame events, which occur within frames on the Timeline. </p><p&g

61、t;　　Mouse and keyboard events</p><p>　　A user interacting with your Flash movie or application triggers mouse and keyboard events. For example, when the user rolls over a button, the on (rollOver) event occu

62、rs; when a button is clicked, the on (press) event occurs; if a key on the keyboard is pressed, the on (keyPress) event occurs. You can attach scripts to handle these events and add all the interactivity you desire. <

63、/p><p>　　Clip events</p><p>　　Within a movie clip, you may react to a number of clip events that are triggered when the user enters or exits the scene or interacts with the scene using the mouse or

64、 keyboard. You might, for example, load an external SWF file or JPG image into the movie clip when the user enters the scene, or allow the user’s mouse movements to reposition elements in the scene. </p><p>

65、　　Frame events</p><p>　　On a main or movie clip Timeline, a system event occurs when the playhead enters a keyframe—this is known as a frame event. Frame events are useful for triggering actions based on the

66、 passage of time (moving through the Timeline) or for interacting with elements that are currently visible on the stage. When you add a script to a keyframe, it is executed when the keyframe is reached during playback. A

67、 script attached to a frame is called a frame script. </p><p>　　One of the most common uses of frame scripts is to stop the playback when a certain keyframe is reached. This is done with the stop() function.

68、 You select a keyframe and then add the stop() function as a script element in the Actions panel.</p><p>　　Once you’ve stopped the movie at a certain keyframe, you need to take some action. You could, for ex

69、ample, use a frame script to dynamically update the value of a label, to manage the interaction of elements on the stage, and so on. For more information, see Chapter 5, “Handling Events,” on page #.</p><p>

70、　　Organizing ActionScript code</p><p>　　You may attach scripts to keyframes and to object instances (movie clips, buttons, and other symbols). However, if your ActionScript code is scattered over many keyfra

71、mes and object instances, debugging your application will be much more difficult. It will also be impossible to share your code between different Flash applications. Therefore, it’s important to follow best practices for

72、 coding when you create ActionScript in Flash. </p><p>　　Rather than attaching your scripts to elements like keyframes, movie clips, and buttons, you should respond to events by calling functions that reside

73、 in a central location. One method is to attach embedded ActionScript to the first or second frame of the Timeline whenever possible so you don’t have to search through the FLA file to find all your code. A common practi

74、ce is to create a layer called actions and place your ActionScript code there. </p><p>　　When you attach all your scripts to individual elements, you’re embedding all your code in the FLA file. If sharing yo

75、ur code between other Flash applications is important to you, use the Script window or your favorite text editor to create an external ActionScript (AS) file. </p><p>　　By creating an external file, you make

76、 your code more modular and well organized. As your project grows, this convenience becomes much more useful than you might imagine. An external file aids debugging and also source control management if you’re working on

77、 a project with other developers.</p><p>　　To use the ActionScript code contained in an external AS file, you create a script within the FLA file and then use the #include statement to access the code you’ve

78、 stored externally, as shown in the following example:</p><p>　　#include "../core/Functions.as"</p><p>　　You can also use ActionScript 2.0 to create custom classes. You must store cust

79、om classes in external AS files and use import statements in a script to get the classes exported into the SWF file, instead of using #include statements. You can also use components to share code and functionality.

80、 </p><p>　　Note: ActionScript code in external files is compiled into a SWF file when you publish, export, test, or debug a FLA file. Therefore, if you make any changes to an external file, you must save the

81、 file and recompile any FLA files that use it. </p><p>　　When you write ActionScript in Flash 8, you use the Actions panel, the Script window, or both. When you use the Actions panel or Script window is dict

82、ated by how you respond to events, how you organize your code, and, most importantly, coding best practices. </p><p>　　About writing scripts to handle events</p><p>　　Events can be categorized i

83、nto two major groups: those that occur on the Timeline (in keyframes) and those that occur on object instances (move clips, buttons, and other symbols). The interactivity of your Flash movie or application can be scatter

84、ed over the many elements in your project, and you may be tempted to add scripts directly to these elements. However, Macromedia recommends that you do not add scripts directly to these elements (keyframes and objects).

85、Instead, you should respond to ev</p><p>　　Using the Actions panel and Script window</p><p>　　To create scripts that are part of your document, you enter ActionScript directly into the Actions p

86、anel. To create external scripts, you can use the Script window (File > New > ActionScript File) or your preferred text editor. </p><p>　　When you use the Actions panel or Script window, you are using

87、the ActionScript editor. Both the Actions panel and Script window have the Script pane (which is where you use the ActionScript editor) and the Actions toolbox. However, the Actions panel, and the Flash authoring environ

88、ment in general, offer a few more code-assistance features than the Script window. Flash offers these features in the Actions panel because they are especially useful in the context of editing ActionScript within a FL<
