Building your first component

In this section, you will build a Dial component. For samples of the Dial component, see the Flash Samples page at www.adobe.com/go/learn_fl_samples. The following samples are available:

• Dial.fla
• Dial.as
• DialAssets.fla

The Dial component is a potentiometer, like those used to measure potential difference in voltage. A user can click on the needle and drag it to change its position. The API for the Dial component has one property, value, that you can use to get and set the position of the needle.

This section takes you through the steps of creating a component. These procedures are discussed in more detail in subsequent sections (including Selecting a parent class, Creating a component movie clip, Creating the ActionScript class file, and Exporting and distributing a component).This section contains the following topics:

• Creating the Dial Flash (FLA) file
• Creating the Dial class file
• Testing and exporting the Dial component
