8. When Flash asks whether you want to import all the files in the sequence, click Yes. Flash imports all the files, placing them in consecutive keyframes. The WMF file may be imported with a border as well as the lines that make up the object. 9. For each keyframe, do the following: a. If your graphic has a border: Click anywhere outside the objects, select just the border, and press Delete. b. If your graphic is imported as one object: Select all the objects and then choose Modify.Break Apart. c. Select the objects and then choose Modify.Convert to Symbol. You can now play your animation. Note that you lose any shading or materials that you created in AutoCAD, so your model has a wire-frame look. You can use fills to modify your 3-D object in Flash to create the appearance of solidity. For an example of creating a simple 3-D animation using this technique, look in the Ch14 folder of the companion Web site for 3d rotation.fla. (The companion site is at www.dummies.com/go/flash8.) You can also use ActionScript to scale, layer, and move 2-D objects interactively according to the movement of the mouse, and this can give the effect of moving in 3-D space. For a cool example of this, see basic_3d.fla in the Ch14 folder of the companion Web site. (Thanks again to Keith Peters of The BIT-101 Lab, at www.bit-101.com, for this file.) What if you don t have a 3-D program? Well, do you have Microsoft Word? Yes, folks, you can create 3-D objects in your lowly word processing program. To create a 3-D object by using Microsoft Word, follow these steps: 1. Open Microsoft Word and, in a new document, open the Drawing toolbar if it isn t already open by choosing View.Toolbars.Drawing. 2. On the Drawing toolbar, click the AutoShapes drop-down arrow and select any shape that you want. You can even draw your own shape by using the Scribble tool (one of the options on the Lines submenu, under AutoShapes). 3. Click in your blank document to place the shape. If you want, use the Fill Color tool to change the fill. Select the shape and then, from the Fill Color drop-down list, select Fill Effects and create a cool gradient on the Gradient tab. 4. Click the 3-D button at the right end of the Drawing toolbar and select from the box that opens a 3-D perspective that you like. You might need to try out a few choices until you get the best effect.

In the following steps, we use AutoCAD as an example. To import an object from AutoCAD, follow these steps: 1. Within AutoCAD, create the 3-D object, display the view that you want to start with, and then choose File.Export. The Export Data dialog box opens. The Files of Type drop-down list should read Metafile (*.wmf). 2. In the File Name text box, enter a name for the file. Add a 1 after the filename. Click Save and select the object when prompted. 3. Rotate the 3-D model slightly. In AutoCAD 2000 and later, you can use the 3D Orbit command for this step. 4. Save this new view as a .wmf file as we explain in Step 2, consecutively numbered from the first file. For example, if the first file is 3d1.wmf, name the second file 3d2.wmf. 5. Repeat Steps 2 through 4 until you ve rotated the model 360 degrees. 6. In Flash, choose File.Import.Import to Stage. 7. Select Windows Metafile (*.wmf) from the Files of Type drop-down list, select the first WMF file that you created, and then click Open. 3 4 5 6 1 2 5 6 Figure 14-2: The circle is 2-D, but it looks like it s rotating in 3-D; here, you see the first quarter revolution. 328 Part VI: The Part of Tens

Test Movie as soon as you develop your animation and continue to test it in this way for each new significant change. Add comments (see Chapter 10) to your ActionScript so that you can figure out what you did when you go back to your movie after your vacation. Use consistent names for symbols. Many Flash users add the type of symbol after the name, so a button could be called Contact_btn, and a movie clip could be called Intro_mc. When you start creating movie clips inside buttons, you might get confused if you don t name your symbols intelligently. Use meaningful names for your instances. If you have three instances of a button symbol, you need to be able to distinguish which is which. You can name them by their purpose, such as Email, Services, and Clients. When you complete work on a layer, lock the layer to avoid making unwanted changes. You re sure to discover other techniques as you become more experienced in Flash. Can Flash Do 3-D? You can t really create 3-D in Flash. Flash is decidedly a 2-D program. But, not to be deterred, Flash users have created many tricks to make you think you re seeing 3-D. One simple approach is to rotate a 2-D object in what appears to be 3-D space. For example, you can draw a circle and scale it in one dimension so that it becomes progressively more of an oval until all you see is a straight line. Continue to expand it from the line through fatter and fatter ovals until you have a circle again. You ve just apparently rotated the circle 180 degrees. Continue until you re finished. You can select a group of frames and copy them or reverse them. (Turn to Chapter 9 for more details.) You can see a simple example in Figure 14-2. You can use shape tweening to create this 3-D effect. You can shape tween a circle into a line and back again to make it look like it s rotating. For fancier results, you can use software packages, such as Swift 3D, that are designed for creating 3-D animation for Flash. Also, some high-end 3-D animation packages, such as Maya, have Flash export capabilities built in. Another technique for simulating 3-D is to import an object from a 3-D program, such as 3D Studio Max, AutoCAD, or Maya. Chapter 14: Ten Frequently Asked Questions 327

1. Decide the amount of the reduction you need to achieve, such as 25 percent. 2. If you have any hidden layers, right-click (Windows) or Control+click (Mac) any layer and choose Show All from the contextual menu that appears. This step ensures that all layers are considered in the reduction. 3. Click the Edit Multiple Frames button (just below the Timeline). 4. Drag the onion skin markers to the beginning and ending frames of your animation. See Chapter 9 if you need more information on how to use the onion skin markers. 5. Choose Edit.Select All. 6. Choose Window.Info to open the Info panel. You see the Width (W) and Height (H), and X and Y coordinates. 7. Multiply all the numbers in the Info panel by the reduction percentage. Write down the results of your calculations, just to be safe. 8. Click in the W (Width) text box and type the new number for the reduction percentage; then press Tab to move to the next box. 9. Repeat Step 8 for the H (Height), X, and Y text boxes. You re done! Flash scales your entire movie by the percentage you specified. You may have to drag everything so that it fits appropriately within your smaller-sized movie. Size requirements are key pieces of information that you need to nail down before building a Flash movie so that you can (you hope!) avoid any need to rescale your movie s size. What Are the Best Movie-Creating Tips? Every Flash user collects a number of techniques that make creating a Flash movie easier. The following items are a few ideas to help you get started. Save multiple versions of your movie by choosing File.Save As. If a problem arises, you can always go back to a previous version and start again. As soon as you have an overall structure, test your movie in a variety of browsers (for example, Internet Explorer, Mozilla Firefox, and Apple s Safari) at various resolutions, if possible. You can more easily fix problems early, before your project becomes too complex. Choose Control. 326 Part VI: The Part of Tens

When you export, you can set the JPEG quality on the SWF tab of the Publish Settings dialog box. You also set the overall quality on the HTML tab. For that quality setting, only the High and Best settings smooth (anti-alias) the bitmaps in the movie. (Refer to Chapter 13 for more information about publishing your Flash movie.) When you import a bitmap image into Flash, you can take the following steps to ensure good-looking results: Save your graphics in the highest quality possible. If you have a photograph, don t import it as a GIF file. Don t overcompress your original bitmaps, but don t import 100K files, either. Find a happy medium. Try saving an image in several formats to see the difference in quality and size. Set the compression type and quality in the Bitmap Properties dialog box. After you import the image, open the Library (choose Window. Library) and right-click (Windows) or Control+click (Mac) the image and choose Properties to open the Bitmap Properties dialog box, as shown in Figure 14-1. How Do I Rescale My Movie s Size? You create a beautiful Flash movie that takes up the entire page. But then your boss says that you need to fit it into an existing HTML page, which translates into reducing the size of the whole thing by 25 percent. What do you do? Get a new boss, if possible. Barring that, you can rescale the size of the movie by following these steps: Figure 14-1: Use the Bitmap Properties dialog box to fiddle with your bitmaps.

Flash movie that you can create only in Photoshop. So you need to use a bitmap image. What format of bitmap do you use? You might not have a choice of format. If your information systems department hands you a logo in JPEG format, you probably have to use it. A trick for changing a file s format is to open an existing bitmap file in an image-editing program. Most let you save that file in another format. At other times, you can choose your format. For example, when you scan a photo, most scanner software lets you choose from among several formats. A digital camera may also let you choose the format. Of course, if you create the bitmap in an image-editing program, you can choose from any format that the program supports. (Turn to Chapter 3 for instructions on importing bitmap images. Hint: Choose File.Import.Import to Stage or File.Import. Import to Library.) Here are some commonly used bitmap formats: The GIF file format, which generally displays well in a browser, can t have more than 256 colors. You can use the GIF format for simple drawings that have a limited color palette, but you may be better off with the PNG format, described later in this list. JPEG files can display many more colors than GIF files and therefore produce more realistic photos and other complex drawings. Although JPEG graphics can be highly compressed to reduce file size, they lose some fidelity as a result. Also, when Flash compresses the file again during export or publishing, you might end up with an unfocused mess. BMP doesn t lose quality when compressed, but the BMP format results in larger file sizes than GIF or JPEG. PNG is a nice compromise between file size and image quality. The PNG format doesn t lose quality when compressed and allows many more colors than the GIF format. And it provides the capability for transparency. Formerly, the PNG format wasn t supported in all Web browsers, but now it is supported in almost all current browsers. If you want the smallest file size but don t want to compromise quality, the PNG format is a good choice. The Flash image compressor works best and most efficiently with images that have not been compressed using techniques that may lose some image quality. Your final result is the .swf file that you publish. Flash compresses bitmaps (as well as the entire movie) when the movie is exported to an .swf Flash Player file. Therefore, you need to think about the entire round-trip journey that your bitmap will make. You might have to test varying bitmap formats and publish the movie for each one to see the exact results. 324 Part VI: The Part of Tens

You need to try choosing Control.Test Movie. Only the simplest ActionScript and button behaviors work on the Stage. If you re trying to run your animation by using the Controller or pressing Enter, try choosing Control.Test Movie instead. If your movie has more than one scene, choose Control.Test Scene to try to isolate the problem to one scene. You need to put each object on its own layer. If you have more than one object on a layer, place each object on its own layer. (Refer to Chapter 6 for a discussion of working with layers.) Animate only one object on a layer. (This solves many tweening problems.) How Can I Sync Sound with Motion? Suppose that you want certain parts of your animation synchronized with specific sounds. For example, you want a bouncing ball to synchronize with the beat of some music you imported into Flash. Without specifically synchronizing the sounds, the sound and the animation might play at different speeds. A faster computer might play the animation faster but doesn t adjust the length of the sound. (For basic information on adding sound to Flash, refer to Chapter 11.) To synchronize animation with the sound, you need to use a stream sound. When you add the sound file to a frame, choose Stream from the Sync dropdown list in the Property inspector. Then adjust the keyframes so that the animation and the sound end at the same time. To be more precise, you can synchronize your animation with specific parts of the sound. To accomplish this task, choose Modify.Timeline.Layer Properties and choose 200% or 300% from the Layer Height drop-down list. You can also click the little button in the upper-right corner of the Timeline and choose Medium or Large for the size of the frames from the option menu that appears. Now you can see the shape of your sound wave more clearly so that you can adjust the keyframes of your animation to match certain parts of the sound. One way to pinpoint which frame to use for placing an animation event is to drag the playhead (the red rectangle) just above the Timeline. This technique lets you control the speed of the animation. You can drag left or right until you find the exact frame that you want to work with. You can then move a keyframe to that frame, for example, to move an animation event to a frame that contains a specific portion of your sound. What Is the Best Way to Import Bitmaps? Maybe you need to put into your Flash animation your boss s photograph or a photo of the product that you sell. Or maybe you want an effect in your Chapter 14: Ten Frequently Asked Questions 323

8. Click the first frame in the Timeline and choose Edit.Timeline. Paste Frames. This pastes the scene you copied from your first movie into your new scene in your second movie. 9. Repeat Steps 1 through 8 for each scene you want to copy from your first movie. 10. Choose Control.Test Movie. Your second movie now includes all the scenes you copied from your first movie. Why Is Motion Tweening not Working? For motion tweening to work, you need to make sure that several pieces are in place. (Review Chapter 9 for the basic instructions on motion tweening.) Motion tweening problems can arise from any number of sources, a few of which follow: You need to tween the right stuff. Make sure that you ve created a group, some text, or an instance of a symbol. Motion tweening doesn t work reliably on anything else. You need an ending keyframe. If you have a dashed line rather than a solid line indicating your motion tween on the Timeline, you didn t properly create an ending keyframe. Undo the steps that created the tween, create an ending keyframe, and try again. You need to tween a keyframe. If you re having trouble changing the length of the tween by dragging on one of the keyframes, that keyframe wasn t included when you created the motion tween. Select the offending keyframe by itself (press Ctrl for Windows or for Mac while you select, if necessary), and select Motion from the Tweening drop-down list of the Property inspector. You need to isolate the problem. If you can t figure out why your motion tweening isn t working, you might have some action or setting that you don t even remember. Movies can get very complex, and comprehending all the relationships and interconnections can be difficult. Try copying to the Clipboard the object that you re animating and pasting it into a new, clean movie. You can copy and paste frames as well. In the new movie, you should be able to analyze the situation more clearly. You need to undo or revert. If the animation worked previously, try undoing your last several actions. You can also try removing any recently created objects or ActionScript. If you can revert to the time your animation worked, you can start again from there. 322 Part VI: The Part of Tens
