This week we are going to create animation. These different animation types are key components in Flash. It is important that you make sure you are able to create all types of animations in Flash.
Creating frame-by-frame animation
Flash provides several methods for creating animation. The frame-by-frame method is derived from the traditional animation process whereby the content is redrawn on each frame with slight differences from the previous frame. When these frames are played in sequence, there is an illusion of movement. Creating frame-by-frame animation is very time-consuming; it is usually used to produce sophisticated motions.
Animating with motion tweening
For a simple moving objective, it’s not necessary to do it frame-by-frame. You can set the position and attributes of your art in the beginning and ending frames and Flash will create all of the frames in between. This is called tweening. Motion tweening can only be applied to symbols; therefore, you must convert your graphics or text into symbols before creating motion tweening. In Flash, two types of tweenings can be created on the timeline: motion tweening and shape tweening. In CS5, motion tweening is further divided into motion tweening and classic tweening.
Animating with shape tweening
Shape tweening works similarly to motion tweening. It follows the same structure of keyframing in the Timeline. The main purpose of shape tweening is to transform the shape of an object into another shape. In the previous chapter, motion tweening could only be applied to symbols. Shape tweening must be applied to an editable shape; therefore, it can’t work with symbol instances. Flash utilizes different colors to represent motion tweening (blue) and shape tweening (green) in the Timeline.
