Anchor Point restrained to scale value

[Kevin Camp]

something like this in the position property will attach the layer to the left edge of the ‘square’ layer:

target=thisComp.layer(“Square”); // change this to your square shaped layer
target.position – [target.width*.5*target.scale[0]/100+width*.5*scale[0]/100, 0]

changing the – to a + will attach it to the right edge.

it will adjust for both the scale of the square layer and the scale of the layer that it is applied to. it will need the square layer to be the width of the layer, so a masked layer or a shape layer may not work as expected, since the actual width of the layer may differ from masked area.

is this what you are looking for?

Thank you so much for your reply. I didn’t think of using the position property of the layer boundaries. I had two questions.

Scaling in X works fine. But in Y. the layer doesn’t move with the scaling. Is there a way of approximating the general position of the layer to match the decaling of the boundary area?

How do you use the top and bottom boondies? is it a -+ +-?

What I’m trying to ultimately achieve is a square with multiple line coming out of the square, 1:1 ratio. The square will then scale up to match a image size, say 16:9. I would like the lines to move with the scale and not change size.
Once again thank you for the reply.

to attach a layer to the top or bottom you would just change it like this:

target=thisComp.layer(“Square”); // change this to your square shaped layer
target.position – [0, target.height*.5*target.scale[1]/100+height*.5*scale[1]/100]

again change the – to a + to change top or bottom.

hi kevin,
trying to do the same, but with several layers. so i’ve put this in:
target=thisComp.layer(index-1);

target.position + [target.width*.5*target.scale[0]/100+width*.5*scale[0]/100, 0]

the problem is, that the layers always move from the scaling layer to the right.
i would like them to move from the scaling layer to both sides the same way.

so i’ ve put it in like this:

target_up=thisComp.layer(index-1);
target_down=thisComp.layer(index+1);
a=target_up.width/2*target_up.scale[0]/100;
b=-target_down.width/2*target_down.scale[0]/100;
…

works fine for three layers, but i have about 30-50 layers.

thanks a lot for the help.
