Another good video from 360|Flex is Advanced State Management by Troy Gardner. If you are not familiar with concepts of states and state machines you should definitely watch it. Even if you are, the guy says some interesting things there. The only thing I don’t quite agree is his implementation of a state machine. I liked what he said about video players and NetConnection dispatching same events meaning different things in different “states” though. I experienced that a lot and in fact used a state machine in my custom video player.

This video doesn’t load from the Web too (at least for me), so use Adobe media Player to watch it.

One of the great videos from 360|Flex is Advanced ActionScript APIs by Jacob Wright. A lot of cool information about Proxy class and using custom metadata. Will definitely be useful even for experienced AS3 developers.

It doesn’t play from the site for me, but plays fine with Adobe Media Player.
