Hi guys,


I have a path that was drawn in illustrator. I want to have an element, a dot, move along this path from the bottom to the top.


I tried plotting the points using the default bezier tween, but it was a little off.


I then tried using the quadratic and cubic methods, but had horrible luck.


Is there an easy way to use this existing path to setup my bezier tween?


Here are my points (assuming that the bottom of the line is 0, 0)


{x:-199, y:-667},
{x:208, y:-947},
{x:315, y:-1072},
{x:350, y:-1156},
{x:381, y:-1303},
{x:342, y:-1497},

If you already have the path, assuming that you were able to convert the illustrator path to the bezier curve, you can try something like this:


See the Pen LuIJj?editors=001 by GreenSock (@GreenSock) on CodePen


Sure the sample uses some random values but is the concept what matters.


If this is not what you're after, please provide a reduce live test in codepen.

Hello Martis,


Here is a simple example of the BezierPlugin:

See the Pen HmGuE by jonathan (@jonathan) on CodePen


You can try adding your points to it.. i left it commented out for the codepen example since the codepen preview area is pretty small to see the paths you provided.

TweenMax.to(".circle", 3, {
          {x:-199, y:-667},
          {x:208, y:-947},
          {x:315, y:-1072},
          {x:350, y:-1156},
          {x:381, y:-1303},
          {x:342, y:-1497}

Please see the BezierPlugin Docs


Does that help? :)
