文章目录
一、Animate the guide layer
(1)打开素材
Open the caterpillar you made last time first“Movie clip animation”.
Delete unnecessary frames.(Save the first frame)
这一次,Let's make a bootstrap animation for a caterpillar.
(2)添加引导层
点击“合成”图层,右键“添加引导层”.
(3)画弧线
在“引导层”图层,我们用【直线工具】画一条直线.
然后用【选择工具】Adjust the straight line,become curved“山坡”.
(4)Adjust the caterpillar
Shrink the caterpillar a bit.
Move its center point down.(The center point can be called up with the free transform tool)
(5)插入帧
在“合成”图层,第30帧,按F6
插入关键帧.
在“引导层”图层,第30帧,按F5
插入帧.
(6)Snap to the center point
在“合成”图层,第1帧,Place the center point of the caterpillar,coincides with the line(adsorbed).
然后是第30帧,Center the caterpillar,Snap to the last line.
(7)创建传统补间
在第0帧-30帧,右键“创建传统补间”.
(8)效果
看了一下效果,有点快,The number of frames can be increased.(在区间内,按F5
添加帧)
Remember to select both the upper and lower layers,Also increase the framerate!
来看一下效果:(If it doesn't work,It can be re-adsorbed)
二、优化
Just made a caterpillar boot animation.
但是,There is an optimization to do here,比如近大远小,Another example is that it is fast when it is close,Slow when far away.
(1)近大远小
1)山顶
on the first summit,按F6
创建关键帧.
按住Shift
键,Shrink the caterpillar a bit.
Other peaks are resized in the same way.
2)山谷
in a valley location,It can be enlarged a bit.
Find the location in the valley,按F6
创建关键帧.
Use caterpillars【变形工具】放大.(按住Shift
键)
Other valleys are resized in the same way.
3)效果
全部做完之后,按Ctrl
+Enter
看一下效果:
(2)近快远慢
1)Ease frame
Start by adding some frame ease before and after.
Select all up and down,鼠标按住不动,Drag back.
The guide layer can be moved directly over it.
合成层,在第18frame byCtrl
+C
复制,然后到第1帧Ctrl
+Shift
+V
原地复制.
Press directly behindF5
Just add frames.(Remember to select both layers)
2)Adjust up and down slopes
Find that frame on the hillside,Then click on this frame.
找到右边“补间”效果—>“CE”.
点击铅笔,调出“缓动”.
①上坡的时候,应该是先快后慢.
在山顶处,Slightly slower.
②下坡的时候,加速.是从慢到快.比如这里.
其他位置同理,自行调节.
这里就不再演示了.
