file in the Lesson05/05End folder to play the animation. The project is an animated title page for a cartoon about an alien creature. In this lesson, you'll animate the alien's arms to move up and down, use a mask to make the eyes blink, use motion tweens to enlarge the alien and position it on the Stage, use a motion guide to loop a spaceship across the Stage, and use shape tweens to morph the smoke from the spaceship into the letter O in the title. 2. Close the 05End.swf file. 3. Double-click the 05Start.fla file in the Lesson05/05Start folder to open the initial project file in Flash. 4. Choose Fit In Window from the View pop-up menu above the Stage, so that you can see the alien on the pasteboard. 5. Choose File > Save As. Name the file 05_workingcopy.fla, and save it in the 05Start folder. Saving a working copy ensures that the original start file will be available if you wish to start over. About Animation Animation is the movement, or change, of objects through time. Animation can be as simple as moving a box across the Stage from one frame to the next. It can also be much more complex. As you'll see in this lesson, you can animate many different aspects of a single character: each limb, for example, as well as eyes, ears, or tongue. You can move objects across space, change their color or transparency, change their size, and even change them into different shapes. To animate objects in Flash, you create keyframes on the Timeline. You've used keyframes in earlier lessons. At each keyframe, Flash records the current state of the Stage: the objects' position, color, size, shape, and other attributes. To create a gradual animation, you can create a keyframe for each frame, and change the objects a small amount for each one. It's faster and easier, though, to take advantage of motion and shape tweens in Flash: you create the first keyframe and the last, and Flash sets up the intermediate frames for you. Motion tweens create animation frames for changes in position on the Stage and for changes in size, color, or other attributes. You've used motion tweens in earlier lessons to animate the movement or brightness of objects on the Stage. Shape tweens create animation frames to change one shape into another. For example, in this lesson, you'll morph a cloud of smoke into a letter O. There is no way to make that change by setting different attributes for the object; the initial object and the final object in the animation are inherently different. Shape tweens make the transformation from one to the other appear smooth. Flash also provides a way to quickly animate motion that is more complicated than a straight path. You can create a motion guide with as complex a path as you like, and then attach your object to it, and apply motion tweening. Flash keeps the object on the path as it progresses through the frames.   Setting Up the Project File The 05Start.fla file contains a single layer called Alien. An alien character is next to the Stage, and the symbols that make up that character are included in the Library panel. Other objects have been created in Illustrator, including the title text, a spaceship, a planet, and a cloud of smoke. Before you animate the objects on the Stage, you'll import layers and symbols from Illustrator and set up the Timeline. Importing Layers from an Illustrator File
