Animating between two position values with a Slider?
I am working on a shot that includes the Advanced Lightning effect. The Lightning needs to grow from one point to another. I have the Origin and Direction linked to two separate nulls that are then animated so that they follow the position of objects in the video.
Is there a way that I can link the Direction parameter to a percentage slider where 0% is the position of one null and 100% is the position of a second null? The ideal result would be being able to animate between the two positions while they themselves are being animating to follow some video.

if you want it variably controlled, I don’t see why a linear wouldn’t work.
//paste in direction and slider will control balance between 2 nulls.s = effect(“Slider Control”)(“Slider”);
x=thisComp.layer(“Null 1”).transform.position;
y=thisComp.layer(“Null 2”).transform.position;n1=x[0];
n2=x[1];n3=y[0];
n4=y[1];s1=linear(s, 0,100, n1, n3);
s2=linear(s, 0,100, n2, n4);[s1,s2];
//you can also add wiggle in slider if you want.

Beautiful. If I could email you a cookie, I would.

How would you utilize this in a 3D environment? I tried modifying the expression a few different ways but wasn’t able to get it to work.
Thanks!

This should work:
s = effect(“Slider Control”)(“Slider”);
p1=thisComp.layer(“Null 1”).transform.position;
p2=thisComp.layer(“Null 2”).transform.position;
linear(s,0,100,p1,p2)Dan
