FAQs

Where can I report a bug, feature request, or rave about my tweening adventures with GSAP?

In our support forums.

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.

Why not give the code away for free?

We firmly believe this licensing model ultimately delivers a superior end product and serves the community better. Open source projects with no funding mechanism typically stagnate and become obsolete. Our goal with this licensing model is to keep the tools extremely accessible while putting in place a mechanism that funds continued support, innovation, and bug fixes. Read The "Why" Behind the GreenSock License for details.
