Hi,

I am trying to replicate the pathAnimation example [1], but using curved lines instead or straight ones. I am stuck at the determination of the position of the point at a fraction of the link.

The example code for straigt line is

`// assume straight lines, for now var start = link.getPoint(0); var end = link.getPoint(link.pointsCount - 1); var x = start.x + frac * (end.x - start.x); var y = start.y + frac * (end.y - start.y); token.location = new go.Point(x, y);`

How can I compute the new location for a curved link?
