  clamp existing wiggle expression

  Posted by Ryan Hagen on September 14, 2018 at 3:03 pm

  Here’s the expression im using, I have a Null with expression sliders driving the wiggle, just want to clamp the value so it doesn’t go into negative values, i’m just not sure how to alter the expression to do this. Thanks in advance for any help.

  w = wiggle(thisComp.layer("Master_ct").effect("PerSec")("Slider"),thisComp.layer("Master_ct").effect("Amt")("Slider"));
[w[0],[29.9]]

  I believe the second line would be
  [Math.max(w[0],0), 29.9]

  Note that you don’t use brackets on the second value, brackets are used to create or read an array.

  That worked, thank you very much Kalleheikki. Also thank you for helping me to understand the bracket usage.
