This tutorial introduces the most basic three kinds of animation methods in Flash: Frame animation, deformable animation and motion animation.

  1. The concept

  One- frame animation --the most basic form of flash animation--is the animation created by changing the contents of each consecutive frame on the edit stage.

  shape Tween Animation --a animation that is implemented by changing the shape or color of a basic shape, and automatically creating a change in the shape of an intermediate process between two key frame endpoints.

  Motion Tweens --the animation that is achieved by changing the position, size, rotation angle, color change of the instance on the stage, and by the program automatically creating the movement change of the intermediate process between the two key frame endpoints.

  2. Differences

1 each frame of the frame animation using a separate screen, suitable for each frame of the images are changing rather than simply moving in the stage of the complex animation. A complex animation that requires subtle changes, such as hair flapping, is an ideal way to do so.

A shape tween draws a graphic at the starting endpoint and then draws another shape at the end endpoint, which enables the effect of a graphic to become another shape.

The motion tween defines the position, size and color of an instance at the starting endpoint, and changes these properties at the end endpoint, which can realize the effect of flip, fade and fade.

2 Every frame of the animation to save the complete data on each frame, motion tween only save the different data between frames, so the use of motion tween relative to frame frame animation, can reduce file volume.

3 The shape of the tween must be used in the broken shape of the graphic, animation tween must be applied in combination, instance, frame-frame animation is not subject to this restriction.

4 frame frame animation each frame is a key frame, the shape tween frame is a green background color, the ends are connected by the solid line arrows, motion tween frame is a blue background color, the ends are also connected by the solid line arrows.

  3. Problems needing attention in application

1 If you create a motion tween, a dashed arrow appears on the timeline, indicating that the tween is unsuccessful, and that the object of the two endpoints should be checked for objects that do not fit between the shape complement or the action tween.

2 can use the deformation hint point to control the shape gradient effect, using the deformation hint point, the two ends of the shape simpler effect the better.
