Animation can be an important part of a Web site, CD-ROM, Demo, or game
The perception of motion is an illusion made up from a series of still images
“Persistence of Vision” is the basis for frame rates in animations
Frames rates of 10-12 fps generally provide smooth computer-based animation
Introduction
4Creating Animations Web Collection: Flash MX 2004 Chapter D
Frame rates lower than 10-12 fps often result in jerky images, while higher frame rates result in a blurred image
Flash uses a default frame rate of 12 fps
Intro to Animation
5Creating Animations Web Collection: Flash MX 2004 Chapter D
Animation is one of the most powerful features of Flash
Basic animation is a simple process– Move an object around the stage– Change an object’s size, shape, color– Apply Special Effects, such as zooming,
fading, or a combination of effects
Two Animation Methods: Frame Animation, and Tweened Animation

Understanding Frame Animations
Also called frame-by-frame animations
Created by specifying an object that is to appear in each frame of a sequence of frames
Useful when you want to change individual parts of an image
Depending on the complexity of the animation, can require a lot of time
7Creating Animations Web Collection: Flash MX 2004 Chapter D
Understanding Frame Animations
Three images used in a Frame Animation
8Creating Animations Web Collection: Flash MX 2004 Chapter D
Understanding Frame Animations
A greater number of images generally suggests less change needed between each image — creating more realistic animationConsider the number of frames in which an image will appear– Fewer frames and the animation may
appear jerky
Consider the frame rate (10-12 fps)
9Creating Animations Web Collection: Flash MX 2004 Chapter D
Creating a Frame Animation
Insert a keyframe on the layer
Place your first drawing on the stage
Insert your next keyframe, and change the drawing
“Onion skinning” may help you placing a series of images

11Creating Animations Web Collection: Flash MX 2004 Chapter D
Understanding Motion Tweening
Motion tweening is far less tedious than Frame Animation– Create a Start and End frame – Flash creates the “in-between” frames
Flash only stores the attributes that change from frame to frame, thus creating smaller file sizes than Frame Animation
12Creating Animations Web Collection: Flash MX 2004 Chapter D
Understanding Motion Tweening
Two types of tweening:– Shape tweening - a “morphing” effect– Motion tweening is used to animate
objects which are moved, resized, re-colored, or rotated
13Creating Animations Web Collection: Flash MX 2004 Chapter D
Motion Tweening requires only a Start and End Frame

14Creating Animations Web Collection: Flash MX 2004 Chapter D
Creating a Motion TweenInsert a starting frame
Insert an ending frame
Make alterations to the ending frame
Go back to the starting frame and choose Insert>Create Motion Tween
Make adjustments through the Properties Panel
15Creating Animations Web Collection: Flash MX 2004 Chapter D
Understanding Motion Guides
A path that will guide moving objects around the stage in any direction
Without Motion Guides, animations would always travel in straight lines
Animations are placed on their own layer beneath a motion guide layer
16Creating Animations Web Collection: Flash MX 2004 Chapter D
Creating Animation with Motion Guides
Two ways to create this relationship– Create a guide layer with a path, then
create a layer of animation an attach– Or, create an animation. Then create a
motion guide layer with a path, and attach
Depending on the type of object you’re animating, you may need to orient the object to the path
17Creating Animations Web Collection: Flash MX 2004 Chapter D
Creating Animation with Motion Guides

Object not oriented to path
18Creating Animations Web Collection: Flash MX 2004 Chapter D
Working with PropertiesTween - specifies Motion, Shape,or none
Scale - tweens the size of an object
Ease - specifies the rate of change between tweened frames
– Ease values are between -100(slow) and 100(fast)
Rotate - specifies the number of times an object rotates clockwise(CW) or counter clockwise(CCW)
19Creating Animations Web Collection: Flash MX 2004 Chapter D
Working with PropertiesOrient to path - orients the baseline of the object to the path
Sync - ensures that the object loops properly
Snap - attaches the object to the path by its registration point
Orient to PathFeature enabledin the PropertiesPanel
20Creating Animations Web Collection: Flash MX 2004 Chapter D
Resizing an Object using a Motion TweenSelect the object in the ending frame and then use the Scale Tool options from the Free Transform tool
21Creating Animations Web Collection: Flash MX 2004 Chapter D
Rotating an Object using a Motion TweenSelect the object in the start or end frame rotate with different options– Rotate with the Rotate Tool option of the Free Transform tool– Rotate Clockwise or Counter Clockwise a specified number of turns or
degrees through the Properties panel– Use Modify > Transform to specify rotation
22Creating Animations Web Collection: Flash MX 2004 Chapter D
Rotating an Object using a Motion Tween
Specifying the rotate settings via the Properties Panel
23Creating Animations Web Collection: Flash MX 2004 Chapter D
Changing an Object’s Color with Motion TweenNumerous ways to change an object’s color over an animation’s time– Change the Tint of the object in the last frame– Change the Alpha of the object in the last frame– Change the Brightness of the object in the last frame– Apply Advanced Effects
25Creating Animations Web Collection: Flash MX 2004 Chapter D
Onion Skin FeatureA feature that allows you to view an outline of objects in any number of framesHelps in positioning animated objects on the stage– Turn Onion Skin feature on via the Icon in
the timeline– Use The sliders to determine the range of
Onion Skin display
26Creating Animations Web Collection: Flash MX 2004 Chapter D
Timeline EffectsMacromedia Flash allows you to combine various animation effects and provides several prebuilt Timeline effects
You can apply Timeline effects to the following objects:
Text
Graphics
Bitmap images
Button symbols
28Creating Animations Web Collection: Flash MX 2004 Chapter D
Animating Text
Like other objects, Text can be animated– The entire text block is animated
unless “Broken Apart”
– Text can be rotated, skewed, scaled, or re-colored
– Motion Tweened Text blocks are automatically saved as Symbols
