Understanding the Brute Force Technique
If you've ever made a flip-book, you already know how to make a frame-by-frame animation. Each page in a flip-book contains a slightly different image so that, when you fan through all the pages, the image is animated. That's what we're doing this hour. However, instead of drawing something different on each page of a book, we'll be drawing a different image in each keyframe of the Flash Timeline.
This hour you will learn features and techniques of Flash that make the animation process easier. However, frame-by-frame animation isn't a "feature" of Flash, it's a technique that you will implement using Flash's features. I mention this because you won't find "frame-by-frame" anywhere in the Flash manual or help files.
