ADT - AIR Developer Tool - ADT is a multi-purpose, command-line tool for developing AIR applications.

PFI - Packager For iPhone - Completely replaced by ADT.

iOS - The OS for iPads, iPod Touch and iPhones

DEVICES SUCK

Your finger is not transparent

THIS NOT THIS

Devices do not have roll over or roll out

TouchEvents are different than MouseEvents flash.ui.Multitouchflash.ui.MultitouchInputMode

Let’s not forget about gestures

flash.events.TransformGestureEvent

Use Enter Frame not Mouse Move

Playbook is wicked fast

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 Manager

October 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

www.smash.io

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 time

stage.addEventListener(Event.DEACTIVATE, onDeactivate); stage.addEventListener(Event.ACTIVATE, onActive);

Piracy can be a problem

Please use Version Control... please
