Editing ActionScript (section)

===Timeline by player version===
* '''Flash Player 2''': The first version with scripting support, its actions included gotoAndPlay, gotoAndStop, nextFrame and nextScene for timeline control.
* '''Flash Player 3''': Expanded basic scripting support, it has the ability to load external [[SWF]]s (loadMovie).
* '''Flash Player 4''': The first player with a full scripting implementation (called ''Actions''), the scripting was a Flash-based syntax and contained support for loops, conditionals, variables, and other basic language constructs.
* '''Flash Player 5''': Included in the first version of ActionScript, it used [[prototype-based programming]] based on ECMAScript,<ref>{{cite web|url=http://www.ecma-international.org/publications/standards/Ecma-262.htm |title=Standard ECMA-262 |publisher=Ecma-international.org |access-date=April 22, 2013}}</ref> and allowed full [[procedural programming]] and object-oriented programming. Design based development.
* '''Flash Player 6''' added an event-handling model, accessibility controls, and support for [[switch statement|switch]]. The first version with support for the [[Action Message Format]] (AMF) and [[Real-Time Messaging Protocol]] (RTMP) allowed for on demand audio/video streaming.
* '''Flash Player 7''': Additions to it include Cascading Style Sheets ([[CSS]]) styling for text and support for ActionScript 2.0, a programming language based on the ECMAScript 4 [[Netscape]] Proposal<ref>{{cite web|url=http://www.mozilla.org/js/language/es4.html |archive-url=https://web.archive.org/web/20070711065258/http://www.mozilla.org/js/language/es4.html |url-status=dead |archive-date=July 11, 2007 |title=ECMAScript 4 Netscape Proposal |publisher=[[Netscape]] |editor=Waldemar Horwat |date=June 30, 2003 |access-date=April 11, 2019}}</ref> with [[Class (computer programming)|class]]-based [[Inheritance (object-oriented programming)|inheritance]]. However, ActionScript 2.0 can [[cross compile]] to ActionScript 1.0 [[bytecode]], so that it can run in Flash Player 6.
* '''Flash Player 8''' further extended ActionScript 1/ActionScript 2 by adding new class libraries with APIs for controlling bitmap data at run-time, file uploads, and live filters for blur and [[drop shadow]].
* '''Flash Player 9 (initially called 8.5)''' added ActionScript 3.0 with the advent of a new virtual machine, called [[ActionScript Virtual Machine 2]] (AVM2), which coexists with the previous AVM1 needed to support legacy content. Performance increases were a major objective for this release of the player, including a new [[Just-in-time compilation|just-in-time]] (JIT) compiler. Support for binary sockets, [[ECMAScript for XML]] (E4X) XML parsing, full-screen mode, and regular expressions were added. This is the first release of the player to be titled Adobe Flash Player.<ref>{{cite web|url=https://www.adobe.com/products/flashplayer |title=Flash Player &#124; Adobe Flash Player 11 &#124; Overview |publisher=Adobe.com |date=April 9, 2013 |access-date=April 22, 2013}}</ref>
* '''Flash Player 10 (initially called Astro)''': Added basic [[3D computer graphics|3D]] manipulation, such as rotating on the X, Y, and Z axis, a 3D drawing API, and [[texture mapping]]. Ability to create custom filters using [[Adobe Pixel Bender]]. Several visual processing tasks are now offloaded to the [[GPU]] which gives a noticeable decrease to rendering time for each frame, resulting in higher [[frame rate]]s, especially with [[H.264]] video. There is a new sound API which allows for custom creation of audio in flash, something that has never been possible before.<ref>{{cite web|url=http://labs.adobe.com/technologies/flashplayer10/ |title=Adobe Labs – Adobe Flash Player 10.1 |publisher=Labs.adobe.com |access-date=December 17, 2009| archive-url= https://web.archive.org/web/20100105125609/http://labs.adobe.com/technologies/flashplayer10/| archive-date= January 5, 2010 | url-status= live}}</ref> Furthermore, Flash Player 10 supports Peer to Peer ([[Peer-to-peer|P2P]]) communication with [[Real Time Media Flow Protocol]] (RTMFP).
* '''Flash Player 11''': The major addition in this version are the [[Stage3D]]-based advanced (graphic card accelerated) 3D capabilities for Windows Desktop, Mac Desktop, [[iOS]], [[Android (operating system)|Android]], and other major platforms. Significant compatibility improvements have been added for the iOS platform, and other non-desktop platforms. Other features include H.264 encoding for cameras, Native [[JSON]] support, [[Bézier curve|Cubic Bézier Curves]], a secure [[random number generator]], [[LZMA]] compression for SWF files, workers to offload some code execution to other processor threads, graphics card accelerated camera feed rendering, memory intrinsics and performance analysis, and the ActionScript Compiler 2.0, as well as some other minor additions.<ref>{{cite web|url=http://download.macromedia.com/pub/labs/flashplatformruntimes/shared/flashplayer11_air3_b1_releasenotes_071311.pdf |archive-url=https://web.archive.org/web/20110714222550/http://download.macromedia.com/pub/labs/flashplatformruntimes/shared/flashplayer11_air3_b1_releasenotes_071311.pdf |url-status=dead |archive-date=2011-07-14 |title=Flash Player 11 and AIR 3 Release Notes for Adobe Labs}}</ref>
