  Simple Array Question

  Posted by Kevin Camin on March 20, 2018 at 2:13 am

  I’m wiggling both properties uniformly below in the two sets of code. My question is why does the second one work? The second value in that array has a [0] designed to it, which I thought was reserved for the first number in the array. Shouldn’t this break the expression? Thanks for reading.

  w = wiggle(frequency, amount);
  [w[0],w[1]]

  w = wiggle(frequency, amount);
  [w[0],w[0]]

  Best regards,

  The second one uses the x component of the wiggle for both the x and y values of the property with the expression, which is what you would do to get scale to wiggle uniformly in both dimensions.

  Your first example doesn’t really do anything different than:

  wiggle(frequencey, amount)

  (assuming a 2D property)
