Creating a tween.

The first step to creating a tween is to have your object, if it is a bitmap image it will have to be converted into a movie clip (F8).

In frame 1 create your object, in this case I am using a cycle from the shape menu.

 The next step is to go to the the frame that you would like you movement to end at and on this fame create a new key frame. With the needle on this frame reposition the object to the end position of the movement.

To create the tween right click on a frame between frame 1 and the newly created key fame. a dropdown menu will appear and from this menu click "create classic tween", by doing this the flash will fill in all of the frames and crate a smooth movement.

This is a very powerful tool as in contrast to traditional "frame by frame" animation this tool can dramatically reduce the amount of time it takes to create the animation, and it is also very accurate in filling in the frames.
