Instead, an independent timer triggers a timer event at a set frequency.In both cases, the events occur in concert with any other events in the ordi-nary functioning of the file, so visual updates, as one example, can continue to occur. Both frame and timer loops will be explained, complete with exa[r]

line, a value is being assigned to the property, so the class knows to call the set-ter. In the second line, no value is assigned, so the class calls the getter, and the property value is retrieved. Now that you have a brief background on imple-mentation, let’s put that information to use in our ong[r]

In addition to the numerous objects that are already predefined in the ActionScript language (such as movie clips, text fields, sounds, and more), you can create your own objects and give them properties—the adjectives of the ActionScript world, describing an object’s ge[r]

The second way was to assign your own class to the movie clip so that it could be created when you created an instance of the class.In ActionScript 3.0, these two approaches are unified into a single linkage class.
