  script to navigate hierachy and change rotation value of all contents

  Posted by Marco Milani on March 29, 2019 at 6:21 pm

  Hi, I’m new to after effects.
  I’m wondering if it is possible to change randomly a property of all subobject, via script and where to place this script!
  
  Basically I thought to loop through the Contents (array?) get the “lettere” object, loop through the child objects, get the property transform.rotation = random()*20-10;

  I’d like to know however to lear not only for this subject but in general.

  I have tryed with this script placing it in transform rotation property of layer “lettere”:
  transform.rotation;
  thisGroup=thisComp.layer(“lettere”).content(“lettere”);//error because it finds a Group when wants Number, Array or Property needed…

  where I can find documentation that permits to learn navigation to hierachy? (I have not found in adobe documentation…surely there is…but I don’t understand very well)
  thanks

  Hey Marco,

  this script by rd will be your first base to hit, as well as will help in a learning curve.

  Select the property you want to get access to and hit ‘Get Property Path’ button.
