you might want to have an element, like the red ball to the left, seem
to fade in or fade out. You might want to use this "alpha fade"
characteristic in combination with another change, as the change of scale
or size here, or with a change in movement, position, color, or rotation.
These effects are easy to accomplish with motion
tweens.
We'll
start with one object and one change. Follow the steps below.
|
- Click a
layer name to make it the current layer, and select
an empty keyframe in the layer where you want the animation to
start. If you're starting fresh, layer one, frame one will be your keyframe
automatically after you've drawn your ball.
- Draw
your circle
on the stage. (You may create an instance, such as the
red ball, a group, or a text block OR drag an instance of a symbol from
the library window.)
- Convert
your ball to a symbol
(Insert > convert to symbol). (Remember, to motion
tween an object you have drawn, you must convert it to a symbol.)
- Create
a second keyframe
where you want your animation to end. ( I used frame
15)
- Modify the
instance in this new keyframe. (Move the item, if you wish. Change its
size, using the transform panel, if you want. Change
its opacity by choosing effect > alpha in the effects panel,
clicking on the arrow to the right of the !00% and moving the slider
close to zero.
- Choose Window
> Panels > Frame. For tweening, select Motion.
- If you modified
the size of the ball, select Scale to tween
the size of the ball.
- If you want
the ball to begin to move or fade in slowly and accelerate toward the
end of the animation, click and drag the arrow next to the
Easing value to -1 to -100. To begin rapidly and decelerate toward
the end of the animation, use a positive value.
- The timeline
should indicate a completed motion teen ( solid arrow on light purple
background). Hit enter, select Control > play, or drag the red rectangular
player head across the timeline to preview your animation. To see it
actually play, choose test movie to preview it in your browser.
