What is the name of the traditional tween animation?

FLASH tween animation, slow in and slow out effect, also called slow motion, when the slow motion value is 100, it means slow motion, and the object stops slowly, not suddenly; When the slow motion value is-100, in order to accelerate the motion, the object moves faster and faster from rest to motion. These two settings are more in line with the laws of nature, and are also the movement laws of animators' professional animation production. FLASH tween animation, the rotation in the attribute can be divided into clockwise and counterclockwise directions. If one of them is selected, when the animation is tested, the object will automatically rotate according to the attributes without manually adjusting the rotation of the object. You can set the number of rotations, that is, how many times the object rotates in a fixed time frame. The larger the value, the faster the rotation speed! Commonly used filters act on movie clips or flash text, and components cannot use filters. Filter effects provide rich animation effects, such as characters, which can be animated by strokes, projections, horizontal blur, vertical blur and overall blur, and can also be adjusted to colors, gradients and other effects of movie clips on the stage.
