First of all I would like to thank you for creating GSAP for JS its simply Amazing!


I was checking out : http://www.greensock.com/customease/ and thought it would be amazing to be able to do something like that in JS/HTML5, so I thought I'll ask.


Mate it may sound a little off-topic but is there a way to maybe draw such a bezier curve in HTML5/Javascript? I want to ask a a animate an object along the bezier path. Is it possible to maybe do something like this, where user can edit the bezier curve?


I hope I make sense, please pardon me if I don't as I am pretty new to JS/jQuery.


Looking forward to hearing about it.


Thanks in advance.

Hi and welcome to the GreenSock forums.


Here are 2 examples of rendering dots along a Bezier path

For the best results you would probably want to feed the same Bezier data you are using for your tween into a canvas API like KineticJS:in: http://www.html5canvastutorials.com/labs/html5-canvas-modify-curves-with-anchor-points-using-kineticjs/

Thanks Carl for taking the time to answer my question.


I am very new to the GSAP libraries but intermediate with JavaScript & jQuery, just trying to climb through the learning curve here. I know it would surely pay off.


I have a couple of more questions but I think creating new threads will be better as others can also refer to the Q&As
