A new layer named Actions is automatically inserted in the Timeline, and the Actions panel opens to display the inserted code snippet. You’ll have to customize some of the code for it to work for this particular project.  Note: Make sure you save external text content as a text-only file in an application such as SimpleText (Mac) or Notepad (Windows). Do not use Microsoft Word, because Word adds unnecessary additional information to the file that interferes with its proper loading. If you use Word, always choose Save As Text Only.

Flash loads the three external text files and displays the contents of the text files in the targeted text boxes. e listing now displays details for a property on Cobble Hill Way instead of 7 th Avenue. e photos and Mortgage Calculator still refer to the previous listing, so the update to the new property is unfinished. However, you can still see in this incomplete example how flexible it is to develop a framework that loads external text content and displays it in text boxes on the Stage. Many professional Flash projects rely on dynamic content fed from external assets such as text files.

Review Answers 1 e SWZ file is an external ActionScript library that contains information that supports TLF Text. If your Flash movie contains TLF Text, it needs the SWZ file to function properly. Flash automatically generates the additional file, which should always accompany your SWF file. 2 Read Only text is for display purposes and doesn’t allow the user to select or edit the text. Selectable text allows the user to select and copy text. Editable text allows the user to select, copy, delete, and edit the text. e contents of all three kinds of text can be changed dynamically with ActionScript. 3 Fonts should be embedded for any text that may be edited or changed at runtime, which means any Editable text box or any text box whose contents dynamically changes, except for text that uses device fonts. Choose Text > Font Embedding or click the Embed button in the Properties inspector to display the Font Embedding dialog box. In the Font Embedding dialog box, you can choose which font, style, and range of characters to embed in your Flash movie. 4 You can wrap text around objects such as photos or graphic elements in a layout by creating a series of linked text boxes, sometimes called threaded text containers. e links establish how overflow text from one text box flows into the next text box. Create the first text box, and then click on the small white box in its lower-right corner. After the mouse cursor changes to a text box icon, click and drag to add the next linked text box. 5 A text box’s contents are determined by its text property, which accepts String values. To change or access the contents of a text box, you must first give the text box an instance name in the Properties inspector. en, in ActionScript, you can reference the contents of the text box with its instance name, followed by a dot, followed by the keyword text.
