You can create artwork and then save that artwork as a symbol that is stored in the Library of your Flash document.. The Library stores all of the reusable art and objects in your movie

Working with Groups,

Symbols, and Instances

Introduction

All vector objects are editable As the complexity of your

doc-ument increases, you can protect artwork from being

inad-vertently changed by storing it in special modes called

groups and symbols Groups provide a quick way to seal a

shape by storing it in a bounding box that can only be edited

by entering a group editing mode Groups are created on the

Stage and are not stored anywhere else For items that are

more global to your movie, you can convert them into

sym-bols The basis for interactivity and animation in Flash resides

in its use of these reusable objects

You can create artwork and then save that artwork as a

symbol that is stored in the Library of your Flash document

Symbols are an efficient way to build your movies because

you can reuse these assets as instances on the Timeline, and

Flash will only store it in your file once Apply ActionScript to

control a movie clip symbol instance and to add interactivity,

place art inside of button symbols to create hit states, or

apply a variety of transparency and color effects to instances

on the Stage The Library stores all of the reusable art and

objects in your movie including symbols, sounds, video clips,

bitmaps, and components It can be organized and sorted for

easy access to your movie's assets A Library can also be

shared with other Flash documents

When you group artwork on the Stage, you prevent it from interacting

with other artwork on the same layer Grouping essentially stores the

artwork in a bounding box that can only be edited by entering a special group editing mode, which you can easily do by double-clicking the group For example, if you draw a shape over another shape on the same layer, the strokes and fills of the second shape will cut through or replace the strokes and fills of the shape directly beneath it Grouping your artwork prevents this from happening You can also use grouping

to combine several shapes into one group so you can manipulate them simultaneously You can ungroup artwork or objects that have been grouped by using the ungroup option or by breaking them apart Doing

so removes the bounding box and the artwork can be freely edited

When objects are grouped they appear on top of shapes that aren't grouped on the same layer Each subsequent group that is created will appear on top of the last This is called the stacking order Flash allows you to change this order with the Arrange command You can send a group or symbol to the bottom of this stack or bring one at the bottom

to the top Additionally, you can change the order incrementally

symbols, such as fonts, graphic symbols, movie clips, and buttons

Flash also stores bitmaps, sounds, video clips, and components in the Library You can also open libraries from other Flash files to quickly transfer assets from one project to another In Flash, you can use a sin-gle Library panel to view the library items of multiple Flash files at the same time
