An interactive movie involves your audience. Using the keyboard, the mouse, or both, your audience can jump to different parts of movies, move objects, enter information in forms, and perform many other interactive operations.
You create interactive movies by setting up actions—sets of instructions that run when a specific event occurs. The events that can trigger an action are either when the playhead reaches a frame, or when the user clicks a button or presses keys on the keyboard. You create instructions that tell Flash what action to perform when the event occurs.
Actions are set up in the Actions tab of the Properties dialog box for either a button or a frame (graphics and movie clips do not have the Actions tab available).
The instructions can be a single statement that tells a movie to stop playing or a series of statements that first evaluate a condition before performing an action. Many actions require little programming experience. Other actions require some familiarity with programming languages and are only for truly sophisticated development.
