End line points following different layers
on Dec 6, 2011 at 11:49:02 pm

This may be simple, but I can't figure it out.

Let's take it's most basic form.

Take layer one, say an image of a cow.
Now take layer two, let's say an image of a duck.

Now I make a line with an arrow starting at the cow's mouth going to and pointing to the duck's bill.

What I want is to be able to animate the scale and position of the cow and the duck and have the starting point of the line (cow's mouth) and ending point of the line with arrow (duck's bill) stay put and track with each object. So if animate the cow to the bottom left and the duck to the upper right the line follows (and stretches as necessary).

Hope that makes sense, and thank you in advance for any solution. The thing I am trying to do is much more complex than this, but the silly example above would apply.

Best,

Kevin

If you change the layers' anchor points to the spots where you want the line to begin and end, you can use the Beam effect and pick-whip the effects start and stop coordinates to each layer's position property. Animate the beam width as necessary to mimic scaling.

And unless you really like a light-saber look, change up the beam's inside & outside colors & softness.

Absolutely perfect.

I created an Adjustment layer, added the beam effect, checked "Composite On Original" so I could see see the line, and pick whipped the beam's starting and ending points to the layers (after changing the origin of each layer as suggested), and VIOLA!!

Thank you so VERY MUCH!!!

You saved me mega-hassle on this project.

Best,

Kevin
