Adobe Flash Introduction

Kyungeun Park

Bitmap vs. Vector based

Bitmap– Bitmaps are made up of single pixels

Vector based– Vector graphics are made up of mathematical

equations

Advantages of Vector-based Drawing Programs

Easy to resize without loss of qualitySmall file size Faster display and download

Animation

Graphics with added motionMotion is illusion of motionSingle image is called a frame

Animation (cont.)

24 frames per second are the threshold for the human eye to perceive single frames showing in sequence as continuous motion

Layers

Layers are like transparenciesHave a stacking orderEasy to make changesAvoid unwanted object interaction

Usage of Layers

Layers avoid unwanted object interactionEach object that you may want to animate

should be placed on a separate layerRule of thumb: If in doubt, place the object

on a separate layer

Frames

Frame – Single image displaying the object or character

Keyframe – Single Image where a significant change to the

object or character is defined

Frames (cont.)

In-between Frames– Incorporate the incremental changes necessary

to simulate movement

Tweening– Process of automatically creating in-between

frames

Symbols

Symbols are reusable objects

Are stored in the library Library is a container for

reusable objectsConvert to symbol

creates symbol and places it in Flash library

Symbol Instances

Instance of a symbol is usage of a symbol in your movie

Help to keep the file size small

Working with Symbols

Library panel– Holds a library’s contents (symbols,

sounds, video clips, and bitmaps in folders)– View Library Window

Working with Symbols

Why use symbols?– Flash uses vectors to hold down file size: each

vector shape is just a set of instructions.

– This fact makes vector shapes efficient to begin with.

– Symbols allow you to reuse elements in a way that's more efficient than duplicating vector shapes.

– Each instance of a symbol is linked to one master symbol, instead of adding a full set of instruction for each instance.

Scenes are compared to chapters of a book.

Animation is broken into smaller chunks called scenes.

Scene panel shows what scenes exist in your movie.

Manipulating Scenes

Frame-by-Frame Animations

Traditional form of animationMade by placing different content in

different framesKeyframe is the frame that hold new

content.

Frame-by-Frame Animations

Keyframes– Blank keyframe: empty frame– Keyframe: duplicates the content of the

preceding keyframe in that layer

Tweening– Process of automatically creating in-between frames

– Flash creates a series of incremental changes to the graphic.

In-between Frames– Automatically generated intermediate frames to simulate

movement

Tweening pattern– Beginning and end of the sequence by placing graphic

elements in keyframes

– Apply tweening process to the beginning frame

Tweening Process

Tweening– Motion tweening– Shape tweening

Difference between motion tweening and shape tweening is:– Motion tweening requires graphics that are in

containers (drawing-objects, groups,symbols, or text boxes quality)

– Shape tweening requires editable graphics (merge-shapes and drawing-objects quality)
