  temp inside an expression

  Posted by Tielman Dewaele on March 18, 2007 at 7:57 pm

  Hello,

  im folowing this tutorial from Mark Coleran(bought).
  Its easty to follow and all :), but when just at the end there go’s something wrong.

  The tut is based like this:
  20 tutorial are parent with NULL01, who is parent on a MASTERNULL01.
  I have 1 CONTROLLER, with 2 control sliders, 1 is for Time, the other for amount:

  T = thisComp.layer(“control(solid)”).effect(“wigg_01_time”)(“Slider”);
  A = thisComp.layer(“control(solid)”).effect(“wigg_01_amount”)(“Slider”)
  wiggle(T,A)

  So far so good…

  Now the NULL01 Rotation i pickwicked it to the R expression see above.
  But the expression gives me:

  temp = thisComp.layer(“Master Null”).transform.orientation[0];
  [temp, temp, temp]

  So i am confused because its not the same in the book : (
  IM a looser in expressions. Im trying realy hard 🙂

  So why does it sais Temp(probebly meaning tempary?), what does it mean?
  Can you help me with this?
  Iff so GREAT!

  Thanks

  T.

  Peace

  I think you’re pickwhipping from the orientation of Null01 to the first value of the orientation of your master null.

  orientation needs 3 numbers for the three axes of rotation, so After Effects tries to be clever and makes a list of three times the same number.

  Just drag the pickwhip to the word ‘orientation’ on the master null, NOT to any of the 3 numbers next to it.

  That way you’re “copying” the entire list of all rotations.

  The same can happen when you’re pickwhipping towards position-values
