Vote: GSAP v12 Timeline API Change


We need GSAP users to vote about a proposed change to the v12 (beta) API. This change applies only to TimelineLite and TimelineMax (ActionScript and JavaScript flavors). It has no effect on TweenLite or TweenMax. If you’ve never used the offset parameter of one of the new convenience methods of the timeline classes, it won’t affect your code either.

Announcing GreenSock Animation Platform (GSAP) v12, now with tangy JavaScript flavor!


Version 12 not only brings more tweenable goodness than ever to Flash, but for the first time ever it does the same for JavaScript too. That’s right. You can use the same animation toolset for your Flash and HTML5 projects. Same API, same user-friendliness, and the same focus on performance and a robust feature set. If you’re a Flash developer, this destroys one of the barriers keeping you from feeling comfortable with HTML5. If you’re a JavaScript developer, this should make advanced animation tasks much simpler and more performant. In fact, it could revolutionize your animation workflow.

BlitMask – Scroll up to 1000% faster


A BlitMask is basically a rectangular Sprite that acts as a high-performance mask for a DisplayObject by caching a bitmap version of it and blitting only the pixels that should be visible at any given time, although its bitmapMode can be turned off to restore interactivity in the DisplayObject whenever you want. When scrolling very large images or text blocks, BlitMask can greatly improve performance, especially on mobile devices that have weaker processors.

ThrowPropsPlugin – tweens that flick, toss, and slide gracefully


ThrowPropsPlugin is a plugin for TweenLite and TweenMax that allows you to simply define an initial velocity for a property (or multiple properties) as well as optional maximum and/or minimum end values and then it will calculate the appropriate landing position and plot a smooth course based on the easing equation you define (Quad.easeOut by default, as set in TweenLite). This is perfect for flick-scrolling or animating things as though they are being thrown…

Code Hinting and Strict Data Typing for TweenLite and TweenMax Vars


Having a hard time remembering all the special properties that you can define in your TweenLite or TweenMax “vars” parameters? I don’t blame you, especially with all the nifty plugins available. If you’d like to get the convenience of code hinting and improved debugging with strict data typing, you’ll love the new TweenLiteVars and TweenMaxVars classes. As of version 5.0, they have been completely rewritten to accommodate method chaining which greatly reduces the amount of code necessary (compared to previous versions).

LoaderMax – Smart AS3 Loading


LoaderMax is a new AS3 loading system that does much more than just getting swf, mp3, css, video, image, text, binary, and xml files into your Flash application. It eats files for dinner, burps, and then asks for 2nds. And 3rds. Yet it’s surprisingly thin. In fact, it can be half the size of most other loading systems even though it delivers a bunch of unique capabilities, some of which you probably never knew you needed but won’t want to live without. Here are a few of the noteworthy features…

This is a legal agreement between you (either an individual or a single entity) and GreenSock, Inc. ("GREENSOCK") for the proprietary GreenSock code known as TweenLite, TweenMax, TweenNano, TimelineLite, TimelineMax, and other copyrighted code that is available for download at (this code and documentation, as well as any updates which may at GREENSOCK's sole discretion be provided to you from time to time, are referred to in this Agreement as "PROGRAM").

If you would like to use the code in a commercially licensed Developed Work for which end users are charged a fee (either for usage or access), simply sign up for the appropriate "Business Green" Club GreenSock membership at

A. You agree that you will not sell, rent, or license the PROGRAM's source code or any derivative works thereof to any third party without the prior written consent of GREENSOCK. Distribution of the PROGRAM as part of your Developed Work is acceptable so long as it is used exclusively as a part of your Developed Work. You agree not to modify or delete GREENSOCK'S existing copyright notices located in the source code.

B. You may use, duplicate, and distribute the compiled object code as embedded in Developed Works created by you, either for your own use or for distribution to a third party so long as end users of the Developed Work are not charged a fee for usage of or access to any portion of the Developed Work. Please see for descriptions of Developed Works that qualify for the "No Charge" license.

C. You may make modifications to the source code exclusively for your own use in order to perform bug fixes or other minor edits required to operate the PROGRAM as originally intended.

A. The license rights granted to you under this Agreement are at no charge, but only in the following circumstances: If on your own behalf or on behalf of a third party you incorporate the PROGRAM into a web site, app, game, program or any component thereof (collectively, "Developed Work"), which in the case of a web site, must be accessible to internet users without payment of a fee of any kind, and in the case of a software application, game, program or component, neither you nor anyone to whom you distribute the Developed Work charges a user a fee of any kind to use such Developed Work or application, game, program or component into which such Developed Work is embedded. The foregoing shall apply regardless of whether you are paid to create such Developed Work.

B. In the event your intended use of the PROGRAM does not meet the criteria for the "no charge" license rights set forth in the immediately preceding paragraph, then you are not licensed to use the PROGRAM under this Agreement and must license the PROGRAM under GREENSOCK'S separate fee-based Software License Agreement which is granted to "Business Green" Club GreenSock members (see for details).

You acknowledge that no title to the intellectual property in the PROGRAM is transferred to you. You further acknowledge that title and full ownership rights to the PROGRAM, including all intellectual property rights therein, will remain the exclusive property of GREENSOCK and you will not acquire any rights to the PROGRAM except as expressly set forth in this Agreement. You agree that any copies of the PROGRAM you make will contain the same proprietary notices which appear on and in the PROGRAM.

GREENSOCK shall not be liable for special, indirect, incidental, or consequential damages with respect to any claim on account of or arising from this Agreement or use of the PROGRAM, even if GREENSOCK has been or is hereafter advised of the possibility of such damages. Because some states do not allow certain exclusions or limitations on implied warranties or of liability for consequential or incidental damages, the above exclusions may not apply to you. In no event, however, will GREENSOCK be liable to you, under any theory of recovery, in an amount in excess of $250. Notwithstanding anything else in this agreement, you agree to indemnify GREENSOCK, its assignees, and licensees, and hold each of them harmless from and against any and all claims, losses, damages, and expenses, including legal fees arising out of or resulting from any negligent act or omission by you.

B. GREENSOCK may, at its sole discretion, provide support services related to the PROGRAM, but has no obligation to do so.

If you at any time fail to abide by the terms of this Agreement, GREENSOCK shall have the right to immediately terminate the license granted herein and pursue any other legal or equitable remedies available.

The arbitrator's decision is final and can be enforced in any court with jurisdiction over such matters.

B. This agreement represents the complete and exclusive statement of the agreement between GREENSOCK and you and supersedes all prior agreements, proposals, representations and other communications, verbal or written, between them with respect to use of the program.
