Tweening is an technique
where an animation program like Flash generates changes in some properties
of an objects from one frame to another and creates animation effects.
This gives another animation without the user having to draw every frame.
The user just need to define the properties of the object in first and
In Flash two types of tweening
is possible - Motion tweening and Shape tweening.
Motion Tweening: Motion
tweening is used to tween the changes in the properties of instances and
other objects. With motion tweening we can change the position, size, rotation,
and skew objects to create motion from one frame to another frame. Additionally,
we can also tween the color of instances, make the color to fade in or
fade out. To tween the color of any object we must convert them into symbols.
See Creating symbols for that.
We can create motion tween
by using the steps below:
1. Open a new file by clicking
File and selecting New.
File > New
A layer will already be there with a blank frame. First name the layer
as "Motion Tween". Select the layer by clicking on layer name.
2. Now draw a object using
toolbox or drag and drop an instance of a symbol that is
in the library on the stage. Now the object will also be in the first frame
Don't forget to convert the object into symbol if it is not a symbol already.
3. Insert a frame on the
layer, upto which point u wanted the animation to last, by
Insert and selecting Frame.
Insert > Frame
right clicking ( for Windows user ) on the point of interest and selecting
4. Select the first frame
of the layer. Click on Insert and select Create Motion Tween
Insert > Create Motion Tween
click ( for Windows user ) on the frame and select Create Motion Tween.
5. Click on last frame and
insert keyframe by clicking on Insert and selecting
Insert > Keyframe
click ( for Windows user ) on the frame and select Insert Keyframe. Now
should look like as shown below. Here I have created an animation
for 20 frames.
6. Now select first
frame and set the properties of the object as you want them to
be in first frame. After that select the last frame and make changes in
properties as per you wanted the animation to look like in the last frame.
The properties that can be changed to create an animation are:
1. Position: We can
change the position of the object at particular keyframe just by
repositioning the object on the stage at that particular keyframe. Select
keyframe and drag the object to the desired position.
2. Scale or Rotate:
We can change the size of the object in particular keyframe to
create zoom in or zoom out kind of effect. To change the size go to Modify
select Transform and click Scale.
Modify > Transform > Scale
can also make the object rotate by using the rotate option. Select the
you want the object to rotate. Go to Modify, select Transform and click
Modify > Transform > Rotate.
user can right click on the object in the particular keyframe and can
the Scale or Rotate option.
3. Color Effects: We can create
few color effects on the objects in Flash and we can

click Rotate option
color options to create color tween. To use these options go to
select Panels and click on Effects. The window will be as as shown

you choose Alpha effect.You can see the change in window as shown
the effect window. You can change the percentage value and can get the
effect. The same can be done with Brightness. With the help of Tint
change the color. With the Advanced option we can change color as well
Make sure before using the effect options that the object is a symbol.
Motion Tweening along
guided path: We can create motion tweening along a user
define path.For defining
the path along with you want the object to move follow the steps written
1. Do first three steps
as we have done while we were creating simple motion
2. Now insert a Guide Layer.
Guide Layer is a type of layer, where you can draw a
for your object to move along. The beauty of the Guide Layer is, it will
not be visible
in the actual movie. We can see it on the stage while we are creating
To insert the Guide Layer click on the icon
at the bottom left corner
of the timeline
window. Alternetive way is go to Insert and click Motion Guide.
Insert > Motion Guide
3. While the Guide Layer
selected, draw a desired path on the stage using Pencil
or Line tool from the Tool
4. Select the layer of actual
object and create motion tween using step 4 and step 5
5. Place the object at the
starting point of the path in first frame and at the ending
of the path in last frame. Now you have created the motion along desired
Shape Tweening: Shape
tweening is used to tween the shape of instances and other objects.
With shape tweening we can create the effect of transforming one
object into another object.
Due to tweening we just need to define the object in first and last frame
of the animation. We do not need to worry about the intermediate layers.
To shape tween the object we must convert them into symbols. See Creating
symbols for that.
