p. 26 D. Symbols and Interactivity What is symbol?In order to create a smaller file size, Flash allows you to create symbol (including graphic, button and movie clip) that can be re-used without adding file size. Symbols reside in the Library. Dragging a symbol from the Library to the stage creates an instance. Flash calls the original a symboland the copies instances. Three types of symbols: 1) Graphic Graphic symbols are effective for re-usable single images. Can be static images or animated images. Can be changed in each instance of the image. Are tied to the main Timeline of the movie. 2) ButtonFlash can create interactive buttons that respond to mouse clicks, rollovers, or other actions. Each button has its own four-frame Timeline. When you select the button behavior for a symbol, Flash creates a Timeline with four frames. The first three frames display the button's three possible states; the fourth frame defines the active area of the button. The Timeline doesn't actually play; it simply reacts to pointer movement and actions by jumping to the appropriate frame. There are 4 states of buttons, they are:
p. 27 Up:A visual state representing how the button appears when the mouse pointer is not over it. Over: A visual state representing how the button appears when the mouse pointer is over it. Down: A visual state representing how the button appears after the user clicks the mouse. Hit: A special, non-visual state that determines the area of the screen which the mouse sees as the “interactive” or “hot” area. ActionScriptAfter you have created the button, you may need to add different actions to this button. Actions can be implemented by ActionScript. ActionScript is the scripting language of Adobe Flash.It allows you to create a movie that behaves exactly as you want. It has its own rules of syntax, reserves keywords, provides operators, and allows you to use variables to store and retrieve information. To add ActionScript, you can: Click Windowson menu bar > Choose Actions to display Actions panel. Action categories Script pane Code Snippets Script Assist 3) Movie Clip A movie within a movie. Retains independent timeline when you insert an instance of symbol into a movie. Keeps going even if the main timeline stops.
p. 28 Advantages to create a movie clip symbol Maintain its own independent timeline. Require only one layer and one frame in the main movie.
