Symbols & Instances
The objective of symbols and instances are to re-use art/elements and cut down on work and file size.
Review of TermsDefinitions taken from glossary at blog
Exercise: for each term, type a paraphrase in a Word document and turn it in at the end of the class session
Symbols, InstanceSymbol: A symbol can be :
-any object or combination of objects -animation-Web button
When you create a symbol, the objects (or animation) become one symbol.
Flash stores the definition of the symbol in the Library.
From the library, the designer can effortlessly insert multiple copies of the symbol into a movie.
Each copy is called an instance.
Take notes and then write your own paraphrase of symbol and instance.
Try to find a metaphor. Example:A symbol is any combination
of elements that can be
reused. It’s like making a
combination of spices, such
as Chinese Five-Spice.
Combine them in a jar
(symbol) and store them in
the cupboard (library).

Students Write Paraphrase of Symbol and Instance
Three Types of Symbols
1. Graphic symbols2. Movie clip symbols3. Button symbols (specialized form of movie symbol)
Next: explanation of each type of symbol
After explanation: we will create each type of animation as a symbol
Graphic Symbols
1. Simple graphic symbols2. Multiframe graphic symbol
Graphic Symbols
Simple Graphic Symbol Multiframe Graphic Symbol
Movie Clip SymbolMovie Clip Symbol:
--reusable, self-contained animation segment ----can be dropped into a single frame in
another animation.
--run independently from the animations to which they have been added
--can have sounds and action
-- good for non-sequential effects like repeating or looping scenes; also interactive
graphics

Multiframe Graphic Symbol vs. Movie Clip Symbol
Confusing: --a movie clip symbols is a series of frames--a graphic symbol can have multiple frames, too
So what is the difference?
A multiframe graphic symbol has to match the animation to which you add it, frame for frame (read further in book under Multiframe Graphic Symbol vs. Movie Clip)
A multiframe graphic symbol can't include sound or interactivity. A movie clip symbol can.
See “moviecountdown.fla” for an example of a multiframe graphic symbol
