  Dragon

  Posted by Christopher Noll on May 24, 2007 at 8:34 pm

  Found this post:

  Position expression:
  thisComp.layer(index-1).position.value_at_time(time-thisComp.layer(“Dragon conrol”).effect(“Slider Control”)(“Slider”))

  Rotation expression
  thisComp.layer(index-1).rotationY.value_at_time(time-thisComp.layer(“Dragon conrol”).effect(“Slider Control”)(“Slider”))

  But my Rotation doesn’t work? The position is offset but not the rotation what gives?

  Also:

  I have Streamers hanging from my dragons bottom jaw that I would like to realistically deform with the jaw movements. Any ideas on how to do that? Each streamer is a separate bitmap.

  TIA,

  Chris

  [Anti_M] “thisComp.layer(index-1).rotationY.value_at_time(time-thisComp.layer(“Dragon conrol”).effect(“Slider Control”)(“Slider”))”

  I’m pretty sure that this line should read:

  thisComp.layer(index-1).transform.yRotation.value_at_time(time-thisComp.layer("Dragon conrol").effect("Slider Control")("Slider"))

  Unless you’re using a much older version of AE in which the syntax is different… Then I can’t be sure =)

  Gives me a message stating no property or method named ‘yRotation’

  This is the correct syntax:

  thisComp.layer(index-1).transform.rotation.value_at_time(time-thisComp.layer(“Dragon Control”).effect(“Rotation Control”)(“Slider”))

  Thanks for getting me on the right track.

  This is a 3D layer you’re referencing right? Make sure that the layer above the layer with the expression is a 3D layer.

  That’s correct if you’re referencing a 2D layer, I thought it was 3D based on your first post… Sorry for misleading you into the right answer (;
