  Jumping to a specific frame inside precomp when hitting specific position

  Posted by Saara Salminen on January 17, 2019 at 8:33 pm

  Hi!
  I wish to achieve an expression of the following:

  When the x-position of current layer hits the x-position of layer “Layer2” (the position values are not separated on either layer, if that matters somehow), the time inside a precomp (“Precomp1”) jumps to a specific frame, like frame 30 for example.

  I’m not too familiar with expressions, and this is probably pretty basic, but I’d appreciate any help I can get.

  Thanks in advance,
  Saara

  Assuming you only want the frame to be frozen when the positions match.. I think this works.

  a = thisComp.layer("Layer2").transform.position[0];
b = thisLayer.transform.position[0];
v = framesToTime(30);
if (a==b) v else value;

  Sorry, that expression should go on TimeRemap on your PreComp.

  This works perfectly, and also makes sense. Thank you very much!
