is there any way to animate along SVG paths already? If not, can you recommend any tool that helps me get the bezier data from SVG, illustrator (or other) paths, so I can use them with GSAP?

Thanks in advance

There is nothing in the platform currently that supports parsing data directly from an SVG.


A tool that has caught my interest is an Adobe Illustrator extension called DrawScript.


What it does is provide a variety of output formats for Bezier curves from AI.


Below is a screenshot showing the curve as JSON data:

The "JavaScript Canvas" output looks like this:


I haven't tried using this data myself yet, but my guess is that it would be entirely possible to parse that data to feed into a canvas drawing API and also pass it to a Bezier tween.

Hi again,

I tried it out, I even got close, but I cant quite find the right way. (JS is mostly for string conversion). I tried "quadratic", as this seemed to be the right one for the export values from drawscript, but with "soft" I came closest. Any help?
