Figure 3.4 Frame-by-frame animation

3_1_FramebyFrame.fla contains the boy walking in place at the center of the Stage.
He is an instance of a movie clip symbol. Double-click on the instance to open its
Timeline. Notice that each frame in the Timeline holds a black dot (Figure 3.5). Each
dot represents a keyframe. Keyframes signify change. In animation, a keyframe art-
ist would draw only the significant changes to a character or object. Since each frame
requires a new graphic to complete the walk cycle, every frame is a keyframe.
