Example 10-23. PauseState.as
1 package

Like the Play state, little is changed with the Pause state shown in Example 10-23,
because it only toggles between playing and not playing, and can’t pause a recording.
The RecordState class is a whole new state. If you look closely, it’s very close to the
PlayState class, with the exception that it can’t transition to the Pause state. Remember
that while in the Record state, the only option is to stop recording, and that is
how the stopAll( ) method is implemented in the RecordState class in
Example 10-24. Save the new state with the caption name as the filename. Be sure to
save it in the same folder as the other files.
