Try this:

 

target = thisComp.layer("Null 2");

d = target.transform.position - transform.position;

radiansToDegrees(Math.atan2(d[1],d[0]))

Subject: [AE] 2d lookAt expression

 

Hi

 

Right now i am stuck trying to write a seemingly simple expression.

I want a normal 2d null to "look at" another 2d null and can't figure out what the expression should look like.

LookAt() seems like it is only for 3d layers? and my goto resource for quick tips for expressions, Dan Ebberts motionscript.com doesn't have anything on something this simple :-)
