Choosing the Right Event Handler. Using event handlers properly presents one of the biggest challenges for ActionScript users—perhaps because most of us haven't given much thought to how things happen around us, and how to apply what we know when we create interactive environments.. However, being mindful of how things and people interact in the real world can go a...

For example, an instance of the Array class (an Array object) can store multiple pieces of information in numerically indexed locations (myArray[0],. How can the array do this? It knows how to do this because it was defined that way by the Array class. The Array class has hidden logic and definitions (code) that work behind the scenes to define...

Because the focus of this book is ActionScript, our discussion in this lesson largely centers on how to work with and use Flash components from a scripting standpoint. For a more thorough overview of components, consult the documentation that comes with Flash.. A component is usually nothing more than a movie clip with some built-in functionality.. Components can be customized...

Component properties can be categorized into two groups: properties that are common to all component instances (to Macromedia-based components, at least), and properties that are unique to each type of component. You may have installed some third-party components that don't abide by the following guidelines. This discussion focuses on the use and capabilities of the components that come pre-installed with...

The buyStuff() function is called only if the variable moneySaved has a value greater than 500. If moneySaved is equal to or less than 500, the buyStuff() function call is ignored and actions immediately below the if statement are executed.. The AND operator (&&) has been added to the statement so that now the buyStuff() function is called only if...

Similar to setting the volume of a Sound object, setting a Sound object's panning is straightforward, as the following example demonstrates:. This code causes the bounce sound to play out of the right speaker only. You can set a Sound object's panning anywhere between -100 (left speaker only) and 100 (right speaker only), with a setting of 0 causing the...

Although most of us can enjoy listening to music without thinking too much about what we're hearing, the vibrations that make up even the most elementary sounds are actually far from simple—a fact made evident by the processing-power requirements of most audio-editing programs. Despite the complexity of even the simplest audio clip, however, sounds can be broken down into three...

methods of the MovieClip class. myButton_btn.onRelease = function(){. myMovieClip_mc.nextFrame();. myMovieClip_mc.prevFrame();. By assigning these event handlers to buttons, you can create navigation controls that automatically advance or rewind a timeline one frame at a time with each click of the button.. For example, if the main movie is being played, the following script places the numerical value of the playhead's current...

If you've been involved with Flash for any length of time, you've seen it evolve from a simple multimedia tool used for creating animated Web graphics and interactive buttons into a multimedia powerhouse that can play external MP3 files, load graphics, play video, talk to a database, and more.. By constantly pushing Flash development to new heights, they make us...

In the preceding exercise, you learned how to create a function and call it. In this. The sole parameter for this function is named myWeight. The value of that parameter is also used within the function definition (near the end of the second line), just as if it were a preexisting variable. Notice that you should associate a data type...

In non-dynamic projects, sounds are placed directly on and controlled from the timeline.. If you want a sound to play in your movie, you must drag it from the library onto the timeline and then indicate when and how long it should play, as well as how many times it should loop on playback. Although this may be a fine...

As we mentioned earlier in this lesson, an expression is a phrase—or a collection of variables, numbers, text, and operators—that evaluates to a value. To the right of the equals sign, you see 6 * 2—this is an expression. When this script is executed, the expression 6 * 2 is replaced by the result of 6 multiplied by 2, or...

Built-In Object Classes. In the next section, we'll briefly review many of the built-in object classes that. Before we do, however, it's important to discuss how to actually get instances of classes into your project in the first place, so you can begin to utilize their power and functionality.. You can create object instances in one of two ways. To...

Your project may contain numerous conditions you can use to control the way your script works or interacts with the user. A movie clip's position, size, or other property is greater than, less than, or equal to another value. The user has a specific interaction with the mouse or keyboard. Text or numeric values are greater than, less than, or...

Although controlling the volume of a movie clip instance with an attached Sound object is a straightforward task, we plan to take an extremely dynamic approach to the process.. Remember in the first exercise of this lesson that we created a Sound object named bounce and associated it with the basketball_mc movie clip instance. This movie clip instance contains a...

The code for defining an ActionScript class exists in its own .as file (remember that the .as file extension stands for ActionScript). If you create 13 classes, you have to create 13 .as files. A class file is nothing more than a text file containing ActionScript code. The name of each class file is the name of the class followed...

Creating a Sound Object. One of the most important points to realize about Sound objects is that you associate each one with a particular timeline in your movie at the time you create the sound. To dynamically control sound on the root timeline, you would need to create a Sound object and associate it with the root timeline. To dynamically...
