PointOnPath Expression not using anchor point

[Jaydude-wb]

I guess I'm missing something regarding the PointOnPath property.

When placing a Solid on the position of a Path Point, it takes te right lower corner in stead of the Anchor Point for the position (see screenshot).

How can I get it to work with the actual Anchor Point?

This is my expression in the position property of the Solid:

p = thisComp.layer("Shape Layer 1").content("Shape 1").content("Path 1").path.pointOnPath(0);
toComp(p);

You need to account for the difference in coordinate origin - center vs. top left corner - and subtract half the width and height.

Thank you Mylenium, that is a logical thing to do, but it feels a bit like a workaround. I don't understand why the anchor point is ignored and, of all points, the right lowerhand corner is taken (while in other Ae-situations, the coordinates are taken from the center or left upper corner).

Do you have an explanation for that behaviour just for me to understand the logic?

Try it this way:

L = thisComp.layer("Shape Layer 1");
p = L.content("Shape 1").content("Path 1").path;
L.toComp(p.pointOnPath(0))

Thank you Dan! That did it!

(Is it because the Solid was in Layer Space?)
