Molehill, Stage3D?“Stage3D for mobile is planned for middle of next year,

but we are working hard on it to make it more like beginning of next year”

- Thibault Imbert, Flash Player Product ManagerOctober 31, 2011

“Adobe AIR 3.2 release candidate is now available for download. This build introduces the Stage3D API to iOS and Android devices, enabling full hardware accelerated 2D and

3D graphics for mobile apps.”- Adobe Labs, compliments of Thibault

Hugs For Thibault

Use a Framework

ANT is your friend(or maven if you’re a cool

kid)

Build servers are awesome

+

Hosting your build servers

Your game can (and will) be interrupted,

at any timestage.addEventListener(Event.DEACTIVATE, onDeactivate);

stage.addEventListener(Event.ACTIVATE, onActive);

Piracy can be a problem

Please use Version Control... please
