Licensing GSAP Club GreenSock Draggable General Support

If I get an annual membership, can I upgrade to a permanent one later?

Sure. You can upgrade directly from within your GreenSock account anytime. Contact us if you need help.

When determining the appropriate membership level, do I need to include only full-time developers? What if my company doesn’t have any?

You must include all freelancers, consultants, subcontractors, etc. in addition to full-time developers.

Can I use the JavaScript version of GSAP for canvas objects or 3rd party tools like EaselJS?

You can animate ANY numeric property of ANY JavaScript object – it’s not just for DOM elements. So yes, you can animate canvas objects, EaselJS assets, and pretty much anything JavaScript-related. In fact, GSAP even has an EaselPlugin to make it easier to animate EaselJS properties. If you need to run logic after each refresh (like to redraw things on the canvas), either use an onUpdate on the individual tween/timeline or add a “tick” event listener to the core Ticker that drives the platform.

Do I need to worry about garabage collection in the JavaScript version of GSAP? What happens when a tween finishes?

No need to worry. Tweens and timelines are automatically made eligible for garbage collection (gc) when appropriate (typically when they finish but if you maintain a reference to an instance so that you can restart it later, for example, it won’t be gc’d out from under you). Basically the system manages gc for you and generally cleans up after itself.

How do I get a license?

Just sign up for a “Business Green” Club GreenSock membership at the level that corresponds to the number of developers in your organization. That’s it!

Who uses GreenSock tools?

Here are just a few: Google, Microsoft, Dow, Sony, Amazon, Fox, EA, Ford, HP, Adobe, Coca-Cola. To see the great work these and other brands are creating with GreenSock tools, swing by our showcase.

Does Draggable use CSS3 animations or transitions for the motion?

Nope. CSS3 transitions and animations have some significant limitations that make them ill-suited for the type of motion that these tools require, so highly optimized JavaScript is used instead. In order to tap into GPU compositing, 3D transforms are used when possible (in browsers that support them) and updates are made using requestAnimationFrame (when available) for maximum efficiency. See for yourself in Chrome Dev Tools - you should see very snappy performance in the timeline. Many other tools like jQuery UI use top/left properties for positioning which don't generally perform as well. These tools have been fully "GreenSocked" so performance is smoking fast, just like the core tweening engine.

Is there a limit to the number of projects I can use GreenSock tools in as a “Business Green” member?

No. The commercial license that comes with “Business Green” Club GreenSock memberships applies to an unlimited number of apps/sites/software/games that your organization sells while the membership is active (see the license agreement for specifics). Please be sure, however, to get the appropriate membership level based on the number of developers associated with your organization.
