Chapter 15. Scripting Lingo > Scripting Navigation

Scripting Navigation

One of the most common uses for Lingo scripts is for setting up a movie’s navigation structure—that is, a series of buttons or menus that permits them to view only the parts of the movie that they want to see, in the order that they want users to see them (Figure 15.30). A navigation structure consists of two equally important aspects: a user-interface design (or front end) that lets users know where there are and how to get to where they want to go; and a technical mechanism (or back end) that makes the user interface work. Designing a good front end is too big a topic to be covered in this book (and is, in fact, the subject of many books in its own right), but this section will show you a few scripting techniques you can use to set up the back end.

Figure 15.30. The buttons in this movie, with their attached Lingo scripts, allow users to decide which parts of the movie they want to see.
