Flash CS3 simulation Art design 2.5: flattening and stretching application

Flattening and stretching are traditional animation techniques that are widely used in realistic and gravity cartoon designs. When a moving object becomes a stationary object, it will deform because of the impact, unless it is a hard complete whole. One thing is important, remember that no matter how many objects are flattened and stretched, it always stays the same size. The amount of flattening and stretching depends on the elasticity of your object. Traditional animations often contain exaggerated compression and stretching. This is a good example of a strong ball. When it strikes the ground, it will be squeezed and deformed. Then it will be pushed up and stretched. In Flash, using a small number of tween and frame-by-step animation, we will get a more satisfactory realism effect.

1. Start from the highest position of the object. Convert it to a component and then use the Free Transform tool to edit its center point. Move the center point to the middle of the bottom.

2. Insert the key frame farther away from the timeline and move the ball vertically to the ground just above the horizon. Add a motion tween to set the easing to "-100". (When entering)
