Layer points to another layer with delay?
I’m using this code so that a layer rotates towards a parent.
Is there a way to add a delay in frames to the rotation?
L1 = thisLayer;
L2 = Null_01;
p1 = L1.toWorld(L1.anchorPoint);
p2 = L2.toWorld(L2.anchorPoint);
delta = p2 - p1;
follow = radiansToDegrees(Math.atan2(delta[1],delta[0])); -

A simple way to achieve this is to add another null which follows the position of the original null with a delay and calculate the rotation value based on the second null. Delay with valueAtTime():
delay = .25;
thisComp.layer("Null_01").transform.position.valueAtTime(time-delay);Kalleheikki Kannisto

Thank you, Kalleheikki. That sounds like a good way to make it work. I appreciate it.

This will take e.g. 99 frames (or whatever you set to t) and use the positions that the values were at at that time to calculate the delta. Adjust as necessary to get the result you want (maybe drop the t for L1(thisLayer)?
t = time-framesToTime(99);
L1 = thisLayer;
L2 = Null_01;
p1 = L1.toWorld(L1.anchorPoint,t);
p2 = L2.toWorld(L2.anchorPoint,t);
delta = p2 - p1;
follow = radiansToDegrees(Math.atan2(delta[1],delta[0])); -
Alex,
Thank you for the expression. I appreciate it. It’s nice to get it all on one layer.
