  How to use expressions to invert position properties?

  Posted by Eduardo Asta on May 9, 2022 at 11:33 am

  I’m building a rig do controle a bunch of layers. A typcal shape layer must move from A to B if its index holds an odd number. But if the index is even, it must go from B to C. It means, it must go in reverse direction.

  The following expressions has worked for the majority of the layers:

  var a;

  inverter = thisComp.layer(index+5).transform.xPosition;

  if (inverter> 0){a = 1} else {a = -1};

  Offset + value*a

  But for some layers the expression is not working at all (see image bellow). Does anyone know how to solve it?

  My best,
