Adobe Flash for Beginners - Graphics & Animation

Class Description: Add spice and movement to your website with Flash graphics and animations. After a tour of the program workspace and key concepts, build your first frame-by-frame animation. Move on to learn basic motion and shape tweening techniques. Work with Flash drawing tools, imported files and special effect filters. Enhance your animations with sound effects. Round off the session with an important lesson on adding Flash files to web pages. With practical exercises, this class delivers a firm grounding in a robust program with endless potential.

1. General Information about this Class

As a beginner to Flash it's natural to feel overwhelmed by the program's vast capabilities. Though Flash was originally designed to produce web-ready graphics and animations, these basic products are now only one of many different things Flash users produce.

Flash is now used to make: Games, cartoons, websites, online video, multimedia projects, photo galleries and much, much more.

While the vast majority of products being produced in Flash are headed for web pages, Flash can also produce non-web related products including offline kiosk displays, presentations and video clips to be utilized in larger video projects.

A. What this class is

This class is designed to get you started in Flash by showing you how to create basic graphics and animations. These original Flash products are still very important items for any web designer to have in their toolbox.

C. Where to go from here

• Online video from Adobe: http://tv.adobe.com/
• Online Video from Lynda: http://www.lynda.com/
• Get a book: amazon.com
• take the next two Flash classes

2. Getting to Know Adobe Flash

A. The Flash Workspace

Like all Adobe programs, the Flash workspace is highly customizable and sticky, (i.e. if you make changes to the workspace it will stick that way until you change it to something else).

For beginners, I highly recommend working in the Classic workspace - it's got everything a beginner needs. To reset Flash to the Classic workspace, from the Menu Bar (along the top) go to to Windows > Workspace > Classic. If you make changes to you Classic workspace and would like to reset it, from the Menu Bar, go to Windows > Workspace > Reset 'Classic'.

B. Flash Drawing Modes

Up until Flash 8, beginners had to deal with vector drawing tools that behaved in an odd manner. Since then, beginners have had the opportunity to draw in a much friendlier environment called Object Drawing Mode. I highly recommend that beginners work in Object Drawing Mode.

To activate Object Drawing Mode you must first select a drawing tool from the toolbar (for example...the Pencil Tool), then activate the mode by clicking the icon at the bottom of the toolbar. Once activated, Object Drawing Mode will be applied to all your drawing tools.

The original Merge Drawing Mode is still available and is loved by many experienced Flash artists and animators.

3. Getting to Know Flash Animation

A. The Flash Timeline

What separates Flash from many other graphic programs is it's ability to generate a file that changes over time. Where this change is developed is in the Timeline.

• The Timeline is divided into two areas: Layers to the left and frames to the right
• Even the most basic animations may well consist of multiple layers
• All animations, by definition, must contain multiple frames
• Animations begin playing in frame 1 and march on to the right
• The speed at which your animation plays is controlled by the frame rate (FPS - frame per second)
• This speed (FPS) is adjustable

B. Types of Frames

As you develop your animation you will be developing your Timeline (both it's layers and frames). All the visual graphics used in your animation must be held within Keyframes. Here are some variations of keyframes you will make and see during development:

Exercise 1 - Frame by Frame Animation

In this exercise we will create a stick figure animation with waving arms. While the finished animation looks childish, this exercise is designed to expose you to a handful of Flash fundamentals including: various Flash drawing tools, timeline layers & frames, stage color, adding text and filters to text, and animation speed (FPS).

This animation features a background image. The image is a multi-layer Photoshop file (.psd). We will need to import this image into our project. Prior to import we will explore some important features of the Photoshop file including: Photoshop layers, image transparency, image Size (pixel count), and image format.

The background images used in this exercise were acquired from flicker Creative Commons, specifically, and with much thanks to Guwashi999, francesco sgroi and kevin.wailes

The Use of Speed (fps) in Frame by Frame Animations

In the above exercise we set the speed of the animation to 12 fps. There will be times when you will change this value to a number that better serves your Frame by Frame animation efforts. Consider the following examples:

1 fps	12 fps		1 fps	12 fps

3. Flash File Types

Fact: When you create a single Flash graphic or animation you'll end up with multiple files. For a beginner it is very important to know the significance of these different files.

4. Bitmap Graphics vs. Vector Graphics

Good news!! There are only two types of visual graphics that you will use in Flash animations: those made up of pixels (bitmap) and those made up of points (vector). It is important to realize that these are two completely different forms of visual graphics (i.e. an apple and an orange). As you build a Flash file you might:

• use Flash's Drawing Tools to create vector graphics (circles, squares etc.) or...
• import vector and/or bitmap graphics from outside of Flash or...
• both of the above

5. Web Browsers and Web Graphics

All Bitmap graphics are made up of rows and columns of pixels. While there are oodles of different bitmap formats, only four are considered to be (more or less) Web browser compatible. And then there is Flash!!

.swf Scaling

If your .swf file contains only vector graphics, it will scale (up and down) beautifully - unlike web bitmap graphics (.jpg, .gif, animated .gif and .png) which tend to become pixelated (or just yucky) when scaled. Sadly...if your .swf file contains bitmap graphics they too will become pixelated when scaled (there is no magic way around this yet).

.gif at 100%	.swf at 100%
.gif scaled to 200%	.swf scaled to 200%

6. Tweening in Flash

When building animations in Flash you have two directions you can go: create each individual frame (frame-by-frame) or ask Flash for help (tweening). You can also have an animation that has both frame by frame and tweening.

"Tween" is actually short for "in-between", and refers to auto-rendering of graphics, by Flash, of the frames between two author defined keyframes.

Flash's has three forms of tweening - motion (new), Classic (used to be called Motion) and Shape. For all types of tweening, you ask Flash to help you with the frames in between.

Exercise 2 - Motion Tween Animation

As mentioned above, Tweens require that the animator defines the beginning and end keyframes before asking Flash to help out with the in betweens.

Motions tweening requires that the same base graphic (bitmap or vector) be used at both ends of the tween (i.e. you can't Motion Tween a circle into a square - that's a Shape Tween - Exercise 3).

Because the same base graphic is used at both ends of the tween, we convert that graphic into a symbol. Symbol use decreases file size, allows for much faster editing and is a prerequisite for Motion Tweens.

Remember...Before you Motion Tween...make a Movie Clip Symbol.

The vector graphics to be used in this exercise will come from an Adobe Illustrator file (.ai). Prior to import we will explore some important features of the Illustrator file including: Illustrator layers, document transparency, document size (pixel count) and Image format.

The fish used in the exercise came from Wikimedia Commons.

Exercise 3 - Shape Tweening

In this exercise we will create a Shape Tween animation. Shape tweens are used when you want to morph one shape into a completely different shape.

The truth about Shape Tweening - While shape tweens sound good on paper they often produce undesirable results. If you want to improve the results of your shape tween you might consider adding more keyframes (i.e. more places where you can control the morphing) or learn about Shape Hints.

5. Adding your .swf to a Web Page in Dreamweaver

By far the easiest way to add your finished Flash animation (.swf) to a webpage is to use Adobe Dreamweaver. Flash and Dreamweaver are both Adobe products and are engineered to work together.

1. In Dreamweaver, you should first define a site, move your Flash animations into the site and create a webpage to hold your .swf.
2. Set the cursor on your webpage where you want your .swf animation to appear. You might set your cursor within a table cell, a <div>, or anywhere between the <body> tags.
3. From the Menu Bar (top) and choose Insert > Media > SWF
4. Dreamweaver will prompt you to attach a JavaScript file to your .html page. This file will help ensure that your .swf plays back correctly. Be sure to agree to adding this JavaScript file. Be sure to upload this file when you upload your .html page.
   • DEMO: Change the background color of a .swf (if visible)
   • DEMO: Set the background color of a .swf to transparent (wmode - transparent)
   • DEMO: The difference between .swf code and image code
