Chapter Lessons

Special effects can add variety and interest to a movie

Morphing– Changing one shape into another

Spotlight– Highlighting an area, or revealing part of

the stage

Animated Navigation Bar– Causes a drop down menu when the

user rolls over a button

Creating Shape Tween Animations

Greater control over shape transformations than with motion tweening

Can shift initial object’s shape into any form you desire

Can also change other properties of color, location, and size

Morphing EffectsChanging one object into another unrelated object

Requires only two keyframes

The number of frames between keyframes determines how quickly the morphing takes place

Shape TweeningCan be applied only to editable graphics– To apply to instances, groups, text blocks

or bitmaps, use “Break Apart”– A “Broken Apart” instance is no longer

linked to its symbol

You can shape tween more than one object at a time as long as all objects are on the same layer

Shape TweeningShape tween an object in a straight line; rotating option unavailable

Use the Properties inspector to set acceleration and deceleration

Shape hints used to control more complex shape changes

Properties Panel Options

Ease– Adjust the rate of change between

frames to create a more natural appearance

• Between -1 and -100 will begin the tween gradually and accelerate

• Between 1 and 100, begin the tween rapidly and then decelerate

Blend– Distributive for smoother, irregular shapes– Angular preserves corners and straight

lines– Flash defaults to Distributive option

Shape HintsControl a shape’s transition appearance during animation

Hints specified at the beginning and end of an animation correspond with one another

Hint suggests how the object should morph

Shape Hints

Create a Mask Effect

A mask layer allows you to cover up objects on another layer(s), and create a window through which you can view various objects on the other layer

Moving the window around can give you a spotlight effect

Understanding Mask Layers

You need at least two layers– Mask layer contains the window object

through which you view objects on the layer below

– The masked layer is the second layer which contains the objects that are viewed through the window

The Masking ProcessSelect masked layer containingobjects to be revealed

Create new “Mask” layer above

Draw a filled shape– Flash ignores bitmaps, gradients,

transparencies

Use Layer Properties Dialog box to declare new layer a mask

The Masking ProcessLock both layers

Mask additional layers by dragging layers beneath the mask layer

To unmask a layer, drag it above the mask layer, or select and declare it normal through Layer Properties

Add Sound

Sound adds impact to Flash movies

Quick process– Import the sound file into the Library– Create a new layer– Select the desired frame and drag the

sound symbol onto the stage– Multiple sounds may go on each layer

Sound FormatsFlash supports– WAV (Windows Only)– AIFF (Macintosh Only)– MP3(Windows and Macintosh)– With QuickTime 4, Flash accepts add’l

sound formats

Managing Sound

The Properties inspector allows you to synchronize sound and add basic effects like fades

Preview sounds in the Library

Adding Sound to Buttons

Open the Button Symbol

Create a sound layer and insert a keyframe in the down frame

Drag a sound from the Library

Working with Scenes

As your timelines grow, scenes help manage the Flash movie

To add a Scene, choose Insert >Scene, or use the Scene command from the Modify menu

The Scene PanelScene Panel allows you to manage and name your scenes– Rename a scene– Duplicate a scene– Add a scene– Delete a scene– Reorder scenes

Working with Scenes

New scenes can be created with new content

Split existing content into multiple scenes by copying and pasting frames from one scene’s timeline to another

Adding Interactivity to Scenes

By default, Flash plays scenes in order

Buttons can cause a movie to jump from one scene to another

Frame scripts can cause a movie to jump from one scene to another

Adding Interactivity to Scenes

Create an Animated Navigation Bar

Provides user with many options without cluttering the screen

Allows the user to go quickly to another location without navigation

Provides consistency in function and appearance

Create an Animated Navigation Bar

The Process– Create a navigation bar– Position the drop-down buttons– Add the animated mask– Assign actions to the drop down

buttons– Assign a rollover action to the

Navigation bar button– Create an invisible button

Using Frame LabelsFrame labels can be used in ActionScript codeAssign a label to a frame as an identifierIf you insert frames into the timeline, the label adjusts to the framesThe descriptive labels help you identify frames
