Making method of tween animation

Tween animation refers to the animation in which a component is placed on a key frame on the time frame panel of Flash, and then the size, color, position and transparency are set. The value of is changed at another keyframe, and Flash will automatically create an animation based on the value between the two keyframes. After the tween animation is established, the background of the time frame panel becomes light purple, and there is a long arrow between the start frame and the end frame. The elements that make up tween animation are components, including movie clips, graphic components, buttons, characters, bitmaps, combinations and so on. But they can't be shapes. Tween animation can only be completed after shapes are combined (Ctrl+G) or converted into components.

Shape tween animation is an animation in which a shape is drawn on a key frame and then changed or another shape is drawn on another key frame on the Time Frame panel of Flash. Flash will automatically create an animation according to the value or shape of the frame between them, which can realize the mutual change of color, shape, size and position between two graphics. After the shape tween animation is established, the background of the time frame panel turns light green, and there is also a long arrow between the start frame and the end frame. The elements that make up the shape tweening animation are mostly shapes drawn with a mouse or a pressure-sensitive pen, rather than graphic elements, buttons and characters. If you want to use graphic elements, buttons and characters, you must decompose them (Ctrl+B) before you can make shape tweens.
