    Flash Symbols

    In this Tutorial you'll learn the basic concepts of Flash symbols, symbol types (graphics, buttons and movieclips), creating and using them.

    What is a Flash Symbol?
    A symbol is a reusable object used/created in Flash. A Symbol can be reused throughout your movie or imported and used in other movies. There are three types of symbols: Graphics, Buttons, and Movieclips.

    A copy of a symbol used in the movie is called an Instance, which can have its own independent properties (like color, size, function, etc.) different from the original symbol. All symbols used in a flash movie are stored in the Library from where you can drag-and-drop new instances of the symbols into your movie. When a symbol is edited all of its instances get updated, but changing the properties, effects or dimensions of an instance of a symbol does not affect the original symbol or other instances.

    Importance of using Flash Symbols
    Using flash symbols is very crucial to the file size of your Flash movie. The Flash file size depends largely on the size of all the graphics and texts used in the movie (both symbols and non-symbols) - here the major advantage of using symbols is that a symbol's size is taken into consideration only once even if it is used a hundred times - this is the true power of Flash. Unused symbols in your library are not counted in the size of your movie.

    Important Tip:
    Get used to using symbols in flash right from the beginning and name them neatly for easy maintenance. It is a very tough job optimizing your file size if you don't use symbols from scratch.

    The Three Types of Symbols

    Graphic symbols are reusable static images that are used mainly to create animations. Any drawn vector/plain text/imported bitmap (photo), or combinations of these, can be converted into a single controllable object: as a graphic symbol. They have only one frame in their timeline. to create graphic symbols.

    1-First create/import the object(s) to be converted into a graphic symbol. Import bitmaps onto the stage using Ctrl+R or by going to File > import.



    2-Select the object(s) with subselection tool in the tool box and then press F8 or Modify > Convert to Symbol.



    3-Select the Graphic Behavior and name the symbol, say 'cuty'.

    4-To edit it at a later point, double-click the symbol in the library (Ctrl + L) or any of its instances on the stage to switch to its symbol-editing mode as shown below. The name of the symbol will appear near the scene name ('Scene 1' by default, as shown below).



    5-Make the necessary changes and click 'Scene 1' to exit from the symbol editing mode and go back to view the main movie's time-line.

    Button symbols are used for timeline navigation - They add interactivity to the movie and respond to mouse clicks, key press or rollovers/rollout, and other actions. You define the graphics associated with various button states (Up/Over/Down/Hit), and then assign actions to the instance of a button. They have 4 frames in their timeline - one each for the up, over and down states, and one to define the hit area of the button respectively.

    Carry out the following steps in Macromedia Flash to create button symbols.
    1. First create/import the object(s) to be converted into a button. Import bitmaps onto the stage using Ctrl+R.
    2. Select the object(s) and then press F8 (or Modify >> Convert to Symbol).
    3. Select the Button Behavior for the symbol and name the symbol say, 'btn_home'.
    4. Double-click the instance of 'btn_home' on the stage to switch to its symbol-editing mode. The Timeline header changes to display four consecutive frames labeled Up, Over, Down, and Hit as shown below.
    5. The first frame displays the drawn vector/plain text used for creating this button, now insert a Key frame (F6) in the frame labeled Over (Flash automatically duplicates the contents of the Up frame).
    6. Now change the color of the object in the Over frame to create a rollover effect in the button.
    7. Insert frames (F5) for the Down frame and the Hit frame (only defines the area of the button that responds to user action and is not visible at runtime).
    8. Save your work and test the Movie (Ctrl + Enter). That's it your simple button is ready!
