An animation optimization of shape tween and optimization of traditional tweening

一、Optimization of shape tween

（1）准备工作

1）写字

2）画圆

新建一个图层,画一个圆.

然后按住Altkey to copy two out.（Three circles on the same layer）

Select the next two circles,右键“分散到图层”.

Then the layers are clear.

3）标明

Type with the text tool：加速、匀速、减速（在图层1上）.

Use them on the circles【Smooth brush tool】写上1、2、3.

Remember to select the corresponding layers separately,Then write the numbers.

（2）Create keyframes and animations

1）创建关键帧

Select them both first,然后在第50帧,右键“创建关键帧”.（或者快捷键F6）

2）创建shape tween

Select all three above,右键“创建shape tween”.

在最后一帧,Move the three balls over.（第50帧）

3）改变速度

Click on the corresponding frame,小球1,然后调成-100.

The third ball,调成100.

（3）效果

看一下效果.

可以看到,球1先慢后快,球2是匀速,球3是先快后慢.The last three balls reach the same spot.

二、Optimization of traditional tweens

（1）准备工作

1）写字

2）画圆

用【椭圆工具】画一个球.

然后用【文字工具】敲上1,颜色为白色.

Then select it as a whole,按F8转化为元件.

Draw the same2个球、第3个球.

也可以,按住Altkey to copy two out.

Then place the two balls behindCtrl+B打散,Change the text above.

Finally press againF8转化为元件.

球2：

球3：

Select all three balls,右键“分散到图层”.

（2）Create keyframes and animations

1）插入关键帧

将它们全部选中,然后按F6插入关键帧.

在最后一帧,Move the three balls to the end.

2）创建传统补间

Select the layer for the three balls,右键“创建传统补间”.

3）改变速度

首先是第1个球,点击它的帧,Then change the small pencil to -100.

第3个球,改为100.

（3）效果

可以看到,球1先慢后快,球2是匀速,球3是先快后慢.The last three balls reach the same spot.

（4）补充

Let's see that we can make the ball spin.

Select the corresponding layers respectively帧,Then rotate the selection“顺时针”.

Like the first ball.

The same goes for the other two balls.

然后看一下效果.

We can also choose how many turns to rotate,Here is the demo1圈.

三、区别

shape tweenCan not do effects such as rotation.

而传统补间Can be rotated.

But both can be adjusted for speed changes.
