Shifting a path starting point

[SirRavenloft]

Hi,

I'm trying to automate moving a path's starting anchor point by a predeterminate step.

However, apparently I can't reference an array in the .setEntirePath() method.

Is this true ou did I blunder?

Thanks in advance.

var MSG_noobjects = "Please select some objects.";
var MSG_nodocs = "You have no open document."
var error=0;

if (documents.length<1) {
   error++;
   alert(MSG_nodocs);
}
if (error == 0) {
   var theObjects=selection;

   if (theObjects.length<1 && error == 0) {
  error++;
   alert(MSG_noobjects);
   }
}
if (error < 1) {
   changePathStarts(theObjects);
}
function changePathStarts(theItems) {
   for (var i = 0; i < theItems.length; i++) {

   if (theItems.typename == "PathItem" && !theItems.locked && !theItems.parent.locked && !theItems.layer.locked) {
   pathLen = theItems.pathPoints.length;

   var pointsarr = new Array();

   for (k = 0; k < pathLen; k++) {//fill array with path's points
       pointsarr.push(theItems.pathPoints[k]);
   }
  pointsarr.push(pointsarr.shift()); //array rotate/shift register right

  var newpath = app.activeDocument.pathItems.add();
  newpath.setEntirePath(Arraypointsarr);

  app.redraw();
   }
  }
}

not sure what you are trying to do but I did notice this.

ln44:  newpath.setEntirePath(Arraypointsarr);

"Arraypointsarr" is undefined....should just be "pointsarr"

Also  line 36 should probably be...pointsarr.push(theItems.pathPoints.anchor);

the dot anchor is where you get the actual position of the point.

I was trying to change a path starting point to another in the same path.

Something like this:

Finally I did it:

var MSG_noobjects = "Please select some objects.";
var MSG_nodocs = "You have no open document."

var error=0;

if (documents.length<1) {
  error++;
   alert(MSG_nodocs);
}
if (error == 0) {
   var theObjects=selection;
   if (theObjects.length<1 && error == 0) {
  error++;
   alert(MSG_noobjects);
   }
}
if (error < 1) {
   changePathStarts(theObjects);
}
function changePathStarts(theItems) {
   for (var i = 0; i < theItems.length; i++) {
   if (theItems.typename == "GroupItem") {//ungroups before processing

   for (var ix = 0; ix < theItems.length; ix++) {
   var item = theItems[ix];
   var itemType = item.constructor.name;
   if (itemType != "Group") {
   continue;
   }
  item.ungroup();
   }
   changePathStarts(theItems.pathItems);
   }
   if (theItems.typename == "PathItem" && !theItems.locked && !theItems.parent.locked && !theItems.layer.locked) {
   pathLen = theItems.pathPoints.length;

   var pointsarr = new Array();

   for (k = 0; k < pathLen; k++) {//fill array with path's points
   pointsarr.push(theItems.pathPoints);
   }
  pointsarr.push(pointsarr.shift()); //array rotate/shift register right

   var newpath = app.activeDocument.pathItems.add()
   for (k = 0; k < pointsarr.length; k++) {
   var newPoint = newpath.pathPoints.add();
   newPoint.anchor = pointsarr.anchor;
   newPoint.leftDirection = pointsarr.leftDirection;
   newPoint.rightDirection = pointsarr.rightDirection;
   newPoint.pointType = pointsarr.pointType;
   }
  newpath.closed = true;

   }
  }
}
for (var k = 0; k < theObjects.length; k++) {
  theObjects.remove();
}
app.redraw();
