  writing a simple script to set null object anchor point in the center?

  Posted by Allison Sabelli on July 18, 2010 at 10:12 pm

  Hi everyone, I need some little help here, I’m very new to AE and scripting is unknown territory, however I’m learning by looking at other scripts and reading a lot. However I’m a little stuck here with the anchor point.

  I’m trying to write a simple script that adds a null object to a scene and set its size and its anchor point right in the center, so far I got everything I need but the anchor point :\

  I might be doing this all wrong, I don’t know ahhaha but how do i set the anchor point to be in the center?.

  Any help is very much appreciated, thanks

  var nw = 50;
var nh = 50;
var myNull = myComp.layers.addNull();
myNull.source.name = "My NUll";
myNull.source.width = nw; // getting this right :)
myNull.source.height = nh;
myNull.source.anchorPoint = ???; //I know should be an array for [x,y,z] but I get errors if i try.
myNull.threeDLayer = true;

  Try this:

  myNull.source.anchorPoint.setValue([x,y,z]);

  Oops, I meant

  myNull.anchorPoint.setValue([mw/2,mh/2,0]);

  Thank you, I was close though 🙂 but I was still adding the = sing after .setValue and that wouldn’t work, long way to learn.
