Flash Tutorials - Creating the Shape Tweening
Creating the Shape Tweening
Select the frame that you want to start the animation with. If it is not the keyframe, transform it to keyframe.
Before creating the figure, add a second keyframe where the tweening is supposed to end. Now select the first keyframe and draw the initial image on it. Note that shape tweening is applied for the figures, not the groups of objects, symbols or edited text. To apply shape tweening to the groups of objects, symbols or edited text you will need to break them apart by going to Modify > Break Apart.
Then, select the next keyframe and draw the final image of the animation on it. Go to Properties > Tween > Shape. The view of the panel will change and the settings of tweening will appear.
If needed, you can change the position of the Ease slider. This option sets the intensiveness of the animation from beginning to the end. It is useful when you want to create the seed-up or slowing down effects.
If you want your animation to be played slowly and then speed up, move the slider down. The "In" word will appear by the slider and in the value field; the negative numbers will appear.
If you want your animation to be played fast and then slow down, move the slider up. The "In" word will appear by the slider and in the value field; the positive numbers will appear.
If you want the animation to be played with the constant speed, leave the slider in the middle and the value equal to zero. You can also enter the numerical values for the Ease parameter from -100 to 100.
Choose the Blend option from the list. Distributive option is selected for the interpolation of the smoothed figures, while Angular option is selected for the angular figures that contain corners and straight lines. If the final view of your figure contains angles and lines, choose the Angular option. Otherwise, choose Distributive option that is set by default.
Test the received animation fragment choosing Play from the Control menu.
