  basic expression query

  Posted by Nico Jones on October 31, 2005 at 11:59 am

  Hi there chaps

  This is, I’m sure, impossibly basic stuff but I’m linking the scale of a solid to a null object using the pickwhip. This works fine, but when I add a +10 to the expression in the solid’s scale property, only the X property is affected.

  So if the null’s scale is 50/50 the solids scale will be 60/50. How do I get both X and Y on the solid’s scale to be the same as the null’s but plus 10?

  Cheers guys

  That is an unexpected result … for me at least. Probably not for Dan … 🙂

  Here’s my shot at it:

  s = thisComp.layer(“Null 1”).scale;
  extra=10;
  [s[0]+extra,s[1]+extra]

  Tying “extra” to a slider expression control would be niftier, but I’ll leave that to you. 🙂

  That should work. This is a little more efficient:

  value + [10,10]
