Sure, you can use Flash MX 2004 without being a master programmer, but as any Flash developer worth his or her salt will tell you, you''''re not tapping all of its power unless you''''re taking advantage of its scripting language "ActionScript 2.0" which offers a more robust programming model and better object-oriented programming support than ever before. Here to take the fear factor out of learning it are Flash veterans and best-selling authors Derek Franklin and Jobe Makar, who demonstrate that scripting is an instinctual process you already know by translating real-life activities into ActionScript scripts. In these pages, you''''ll find methodologies and techniques for building over 40 real-life Flash ActionScript projects, including sample games, applications, Web sites, and more. New in this edition are coverage of ActionScript 2.0, Web services, Components, Printing, Video, and more. On the companion CD, you''''ll find all the project files and images you need to complete each project.
Lesson 3. Understanding Target Paths
Communication is an important part of our everyday lives. We communicate by telephone, email, postal mail, and so on. Because nearly everyone communicates in a similar fashion, without a system of individual identification it would be impossible to route those communications from one person to another. We have unique phone numbers, email addresses, and street addressesall of which to help ensure that communication intended for us actually reaches us.Just as phone numbers, email addresses, and street addresses lead communication to its intended recipient, Macromedia Flash target paths lead one timeline to another, allowing them to communicate. In this lesson, we'll take a look at the target paths used in typical Flash projects and show you how to use Flash's powerful ability to have timelines talk to each othera capability you'll use to give your projects more depth and sophistication.
A thorough understanding of target paths and how to use them will enable you to create sophisticated applications where independent timelines can work together to perform tasks. The "windowed" Flash application shown here (which we'll create in this lesson) is an excellent example of the way target paths can be used to give a project more depth and sophistication.
WHAT YOU WILL LEARNIn this lesson, you will:Gain an understanding of the hierarchy of timelines in Flash moviesLearn about absolute and relative target pathsLearn how movies communicate with each otherUse the parent-child relationship in movies to create an "effect" clipControl specific timelines within a single projectControl movies loaded into levelsLearn how to make global references to various ActionScript elementsAPPROXIMATE TIMEThis lesson takes approximately one and one half hours to complete.LESSON filesStarting Files:Lesson03/Assets/currentTarget1.flaLesson03/Assets/rootTarget1.flaLesson03/Assets/parentTarget1.flaLesson03/Assets/movieclipTarget1.flaLesson03/Assets/backgroundControl1.flaLesson03/Assets/textBox1.flaLesson03/Assets/levelTarget1.flaLesson03/Assets/levelTarget3.flaLesson03/Assets/backgroundControl2.flaCompleted Projects:currentTarget2.flarootTarget2.flaparentTarget2.flamovieclipTarget2.flatextBox2.flalevelTarget2.flalevelTarget4.flabackgroundControl3.fla
