  add Expression with a Script

  Posted by Matthias Weiner on March 12, 2018 at 12:41 pm

  Hello,
  I’ll hope this is the right forum for my question. I have written an expression and wanted to ad this by a script to my selected layer. The problem is that I can’t add this expression in between the “” with all its special chars, commands and comments. I only can convert the expression to a binary and add this in between the “”. I will share my code in the hope of getting help ☺ The script adds the expression to every puppet-pin position to the selected layers. The expression finds special named NULL’s in a limited distance and take the closest and get its position. I developed this to manage fast usage of facetracking-points as NULL’s to transform a layer with nearly same positioned puppet-pins. Here is an example Video: https://www.facebook.com/picmention/videos/1400056170026071/

  Thank you!

  //Script by Picmention - 2018

  here is the expression I want to add in my script:

  //Script by Picmention
//Puppet-Master V1.3
//19.01.2018

  try
  {
  //Hitname
  hitname = "NULL";
  l_over = "NULL_Hand_Links";
  l_override = false; //if true use l_over instead of hitname-search
  force_vec = true; //true, false, auto)

  //Max Radius
  maxRadius = 64;

  //TheChoosen
  theChoosen = -1;
  tCDist = maxRadius;

  //Länge des Hitnames
  c_lengh = hitname.length;

  //Test if this is a vector mask
  try{content;hasCont = true;}catch(e){hasCont = false};

  //Check if source is vector based layer. If so we implizit that vector optimization is enabled
  try{ln = source.name;
  ll = ln.length;
  if(ln.substr(ll-2,2) == "ai") hasCont = true;
  if(ln.substr(ll-3,3) == "pdf") hasCont = true;
  if(ln.substr(ll-3,3) == "eps") hasCont = true;
  }catch(e){};

  if(force_vec == true) hasCont = true;
  if(force_vec == false) hasCont = false;

  if(hasCont == true) p1 = value;
  else p1 = toComp(value, inPoint);

  for (i=1; i <= thisComp.numLayers; i++)
  {
  l = thisComp.layer(i);
  s = l.name.substr(0,c_lengh);

  //Test auf Hitname
  if(s == hitname)
  {
  p2 = l.toComp(l.anchorPoint, l.inPoint);
  dist = length(p1,p2);
  if(dist <= maxRadius && dist <= tCDist)
  {
  tCDist = dist;
  theChoosen = i;
  }
  }
  }

  if(l_override == true) theChoosen = thisComp.layer(l_over).index;

  //Var
  l = thisComp.layer(theChoosen); //The NULL object where the movement depends on
  p1 = l.toComp(l.anchorPoint, l.inPoint); //The position at inPoint time on the comp
  p2 = l.toComp(l.anchorPoint, time); //The position at current time on the comp

  //Calc
  if(hasCont == true) dif = p2-p1; //Use this calculation if it is a vectorized layer
  else
  {
  p1b = fromCompToSurface(p1, inPoint); //Calculate the position on this layer at inPoint time
  p2b = fromCompToSurface(p2, time); //Calculate the position on this layer at current time
  dif = p2b-p1b; //Calculate the difference
  }
  temp = value+dif; //Add the initial value to the difference

  //Out
temp; //print out
}
catch(e)
{
//Die Antwort auf alles
value;
}
