Expression To Grab Path Coordinate

Wed Apr 16, 2008 11:48 am

Hi All,

I am trying to create an arrow that travels along a path. I want it to bend around the path as well.

I have come up with a possible solution. I am using the Vegas effect with only a single segment, this get's me the body of the arrow bending along the path. So the challenge is to get the arrow head to follow the path.

So I created a new solid and copied the Mask Shape to the clipboard and pasted it into the position property of the triangle layer (a solid with a triangle mask). This gets me my triangle traveling along the path, but it seems to be about 180 degrees out of phase with the Vegas stroke.

I am just wondering if there is an expression I could use to adjust the tracking?

Is there a better way to do this?

Thanks! :P
