Getting Around in Flash

As mentioned earlier in this hour, an important concept in Flash is to understand where you are at all times. If you think you're in the Library, editing the contents of a symbol, for example, you better hope you are really there. It can be confusing because, although it's always possible to figure out where you are in Flash, the clues are often subtle. The following sections look at how you can determine where you are by reading the subtle clues in the interface.

The Current Layer

Although there's just one main Timeline, earlier in this hour you saw how you can have several layers within the Timeline. At this point you should open a new file and add a layer so that you can explore it; you do this by selecting Insert, Timeline, Layer. One important concept is that you can be in only one layer at a time. That is, if you draw or paste graphics, they are added to the currently active layer. The current layer is the layer with the pencil icon, as shown in Figure 1.13. You can single-click another layer to make it the active layer (notice that the pencil moves to the layer you click). The key here is to always pay attention to what layer you're currently editing. For example, if the current layer is locked, you won't be able to affect it at all.

The Current Frame

In the Timeline, a red marker indicates which frame is currently being viewed (see Figure 1.14). This red current-frame marker can be in only one frame at a time—the frame you're currently editing. Initially you'll find that you can't move the current-frame marker past Frame 1 unless your file has more frames. You'll have plenty of opportunity to do this later; for now, just realize that the red marker indicates the current frame. If it helps, imagine a time machine. You can visit any moment in time, but you can visit only one moment at a time.

Figure 1.14. The red current-frame marker (on Frame 11 here) can be in only one frame at a time. It's important to realize where this current-frame marker is located at all times.

The Current Scene or Current Symbol

By far, the most difficult concept for new Flash users is that in Flash, there's more than one Timeline! A large or complicated movie can be broken into several scenes. You can think of scenes as chapters in a novel. Deep inside Flash, there's always just one long Timeline (just like a novel has one continuous story), but if you break a file into scenes, you can access the scenes individually. This is a nice feature because it means you can easily change the order or sequence of the scenes. It should be apparent that at all times you should know in which scene you're currently working. The name of the current scene is always listed above the Stage (and above the Timeline if it's docked), on what is called the edit bar—or what I often call the address bar. The default name is "Scene 1," and you should see this next to the icon for scenes—a movie "clapper" (see Figure 1.15).

The edit bar often includes more information than is shown in Figure 1.15. When you learn more about the Library in Hour 4, you'll see how you can nest instances of symbols inside other symbols. When you double-click a complex object such as a symbol to edit it, everything else on the Stage dims (indicating that those other items are not editable). (This behavior of going inside one object to edit its contents also applies to grouped objects and so-called drawing objects—both of which you'll learn more about next hour.) In all cases, the best way to determine exactly what you're currently editing is to look at the edit bar. You might see "Scene 1: Group" (as shown in Figure 1.16). This means that you're in a group that is in Scene 1. Sound pretty hairy? Well, it's not really so terrible because the edit bar is very clear—you just have to remember to look there.

Navigating Through the Interface

You've seen how the Flash interface gives you clues that tell you where you are at all times. But how did you get where you are in the first place? And how do you get out? Navigating through a Flash file is easy—and maybe that's why it's so easy to get lost. Let's look at a few ways to get around.

The edit bar contains the hierarchy of your current location, and it also provides a means of navigation. You can click the edit bar. If, for example, you're inside a symbol within Scene 1, you should see "Scene 1: SymbolName." If you simply click Scene 1, you are taken back to that scene (see Figure 1.17). Any time you see the edit bar, you can navigate back through the hierarchy. Remember that the edit bar provides information and that it's clickable.

Finally, you should notice two menus way off to the right of the edit bar: Edit Scene and Edit Symbol (see Figure 1.18). From these two menus, you can jump to any scene or symbol in the current movie. Of course, if you have no symbols and just one scene, using these menus won't be very interesting. However, in big files, these menus provide a quick way for you to get around. If you want, you can open one of the sample files inside the folder Sample and Tutorials, which is adjacent to your installed version of Flash (for example, C:\Program Files\Macromedia\Flash 8\Samples and Tutorials).

There are plenty more ways to get around in Flash, and you'll see them all in this book. For now, try to feel comfortable moving around and be sure to notice all the clues that Flash gives concerning where you are.

How Not To Get Lost

As a reference, here's a list of common ways to get lost and how to find your way home. This is a list based on my experience teaching new students—as well as my own experience getting lost! I'm including things here that you haven't been exposed to yet so feel free to mark this page and revisit it later.

• Edit bar. By far the most common problem is overlooking the fact the edit bar has changed to indicate you're inside a symbol or group or drawing object. I've already said to keep an eye on the edit bar. But what if it's gone? Amazing but true: You can hide and restore the edit bar via the menu Windows, Toolbars, Edit Bar. I can't imagine selecting this on purpose, but now you know how to bring the Edit Bar back.

• Changing Colors. The half-dozen or so color swatches can both determine the color you're about to draw as well as change an existing color. Remember, if you have something selected, it will change when you change the color swatch. Only when nothing is selected can you set the color for what you're about to draw. Plus (and this will become clearer next hour) there can be two colors for an object: the stroke and the fill. You'll see a pair of swatches quite often indicating these independent colors.

• Hiding docked panes. I didn't cover this yet but when a panel or group of panels is docked into the Flash interface—above or to the right of the stage—you'll see a divider line. Not only can you click and drag to relocate the divider but there's a subtle arrow button in the center of the line (shown in Figure 1.19). If you click the arrow button the entire group of docked panels is hidden. This is nice because it immediately gives you more space on the other side of the divider, plus you can quickly restore the divider by clicking again. However, it's also easy to get lost because you may not realize a bunch of panels are simply tucked away. By the way, Flash uses the same divider line and arrow button in a few other places such as the Help panel.

  Figure 1.19. Dividers can resize the space between panes full of panels, and the little arrow button can quickly collapse (and hide) all the panels.

• Properties panel. It's important to know what sort of object you have selected. For example, if you draw a shape with the Brush tool the Properties panel will display "Shape" when you select that shape. There are other object types that you'll learn about over the next few hours—I promise you'll understand the attributes of each. People often forget the Properties panel tells you what you have selected. You may think something is a shape (or other type of object) but use the Properties panel to know.

• Info panel. The Info panel displays (and lets you edit) the size and location of any selected object. In addition, it has a grid of 9 squares with one black square—either top left or center (which you can change by clicking). This simply makes the Info panel reflect coordinates for the top left corner of the selected object or the center of that object. What's very easy to overlook, however, is the setting you make using the Info panel affects the coordinates displayed in the Properties panel's W, H, X, and Y fields. That is, you set your preference (top left or center) in the Info panel and that affects the numbers that appear in the Properties panel.

That's it for the big pitfalls. Naturally, there are many more but I'll be sure to guide you past them as they're encountered in later hours.
