  wiggling variables within an expression

  Posted by Tom Gomez on July 21, 2018 at 10:42 pm

  Greetings Expression Gurus,

  Super quick question:

  For some positioning stuff I’m doing, I have this simple expression to get my x/y coordinates:
  X=(effect(“X click”)(“Slider”))*32+1376;
  Y=(effect(“Y click”)(“Slider”))*32+672;

  No problem.

  But then I’d like to affect the resulting x/y coordinates with this wiggler–which I modify with sliders on a different layer:
  wiggle (thisComp.layer(“NETWORK CONTROLLER”).effect(“wiggle X”)(“Slider”),thisComp.layer(“NETWORK CONTROLLER”).effect(“wiggle Y”)(“Slider”))

  How do I get it to wiggle the X and Y of the first part of the expression?

  THANKS!

  Tom

  Something like this probably (not tested though):

  X=(effect(“X click”)(“Slider”))*32+1376;
  Y=(effect(“Y click”)(“Slider”))*32+672;
  L = thisComp.layer(“NETWORK CONTROLLER”);
  w = wiggle (L.effect(“wiggle X”)(“Slider”),L.effect(“wiggle Y”)(“Slider”))-value;
  [X,Y] + w

  Alternately, you can add a wiggle expression directly to the sliders.
