ActionScript 3.0 Design Patterns

Adding More States and Streaming Capabilities | 391

The test module, Example 10-27, that follows in theTestFMS.asclass is a bit more

robust than the previous testing classes used. (In fact it would have probably been a

good idea to break it down into its own class set, but we’re focusing on using it to

demonstrate the State design pattern, and so a humbler test class emerged.) Be sure

to place a copy of theNetBtn.asandBtnState.asfiles in the folder where you’re sav-

ing the rest of your files for this application.
