In Flash, symbols help keep file sizes small.
Once an object has been made into a symbol, all further instances of the symbol use the basic information. Select the blue circle. From the Insert pull down menu, select New Symbol... In the Symbol Properties
dialog (shown above), enter Blue Circle for the name. Check the Graphic radio button and press OK. Repeat this step and convert the two rectangles to symbols. |
The symbols reside in the Library (Window > Library) Once in the Library symbols can be dragged onto the stage to create new instances. |
Right click in frame 30 on the Circle layer.
From the pop up menu, select Insert Key Frame. A rectangle with a black dot appears to indicate a key frame. Key Frames are used to create action and/or to change the size, position, and other properties of the symbol.

In order to create a transition between the
two instances of our circle, we need to create a tween. Tween, by the way, is an old animation term for creating a series of frames in-between the two key frames. Right click on frame 1, Circle layer
. From the pop up menu, select Create Motion Tween. An arrow appears between frame 1 and frame 30 to indicate the starting and ending point of the tween.
Repeat these two steps to create key frames and motion tweens for the two rectangles. Place all key frames on frame 30. |
