  How to retrieve index of the effect?

  Posted by Satya Meka on May 25, 2009 at 6:05 pm

  Hi,

  If I apply a number of effects to a layer. Is there anyway I could retrieve the index of a particular effect in that layer?

  Thank you,
  Satya Meka.

  Do you mean retrieve it with an expression applied to that effect? If so, yes – but it can be a bit tricky. Use propertyGroup() to move up through the property groups until you get to the effect itself.

  For example, to get the Numbers effect to display it’s own effect index you could use this expression:

  thisProperty.propertyGroup(1).propertyIndex

  propertyGroup(1) moves up one level from the propety the expression lives in, propertyGroup(2) moves up two levels, and so on. Hope that helps.

  Awesome! So we can get the index of anything with respect to its property group, by applying the expression to its child parameter. Thank you so much, it helps a lot.
