# How to make curvature on shapes with a script?

In relation to the post on GitHub by Mike Hale and Vladimir Carrer I want to be able to add a curvature to the specific line, or to be more precize with an example, on a rectangle I just want to make curve on one of the sides, that also have to apply to every polygon.

In the loop:

``````for (i = 0; i < y; i++) {
lineArray[i] = new PathPointInfo;
lineArray[i].kind = PointKind.CORNERPOINT;
lineArray[i].anchor = arguments[i];
lineArray[i].leftDirection = lineArray[i].anchor;
lineArray[i].rightDirection = lineArray[i].anchor;
}``````

I know that lineArray[i].leftDirection = lineArray[i].anchor; and lineArray[i].rightDirection = lineArray[i].anchor; are responsible for creation of the curves. How could I do that in the function DrawShape()?

Thank you,

Damian

Well, for example, like this  function DrawShape() { var doc = app.activeDocument; var y = arguments.length; var i = 0; var lineArray = []; for (i = 0; i < y; i++) { lineArray[i] = new PathPointInfo; //lineArray[i].kind = PointKind.CORNERPOINT; //lineArray[i].anchor = arguments[i]; //lineArray[i].leftDirection = lineArray[i].anchor; //lineArray[i].rightDirection = lineArray[i].anchor; lineArray[i].kind = PointKind.S...

Well, for example, like this 🙂

``````function DrawShape() {

var doc = app.activeDocument;
var y = arguments.length;
var i = 0;

var lineArray = [];
for (i = 0; i < y; i++) {
lineArray[i] = new PathPointInfo;

//lineArray[i].kind = PointKind.CORNERPOINT;
//lineArray[i].anchor = arguments[i];
//lineArray[i].leftDirection = lineArray[i].anchor;
//lineArray[i].rightDirection = lineArray[i].anchor;

lineArray[i].kind = PointKind.SMOOTHPOINT;
lineArray[i].anchor = [arguments[i][0], arguments[i][1]];
lineArray[i].leftDirection = [arguments[i][2]!=undefined?arguments[i][2]:arguments[i][0], arguments[i][3]!=undefined?arguments[i][3]:arguments[i][1]];
lineArray[i].rightDirection = [arguments[i][4]!=undefined?arguments[i][4]:arguments[i][0], arguments[i][5]!=undefined?arguments[i][5]:arguments[i][1]];
}

var lineSubPathArray = new SubPathInfo();
lineSubPathArray.closed = true;
lineSubPathArray.entireSubPath = lineArray;
var myPathItem = doc.pathItems.add("myPath", [lineSubPathArray]);

var desc88 = new ActionDescriptor();
var ref60 = new ActionReference();
ref60.putClass(stringIDToTypeID("contentLayer"));
desc88.putReference(charIDToTypeID("null"), ref60);
var desc89 = new ActionDescriptor();
var desc90 = new ActionDescriptor();
var desc91 = new ActionDescriptor();
desc91.putDouble(charIDToTypeID("Rd  "), 0.000000); // R
desc91.putDouble(charIDToTypeID("Grn "), 0.000000); // G
desc91.putDouble(charIDToTypeID("Bl  "), 0.000000); // B
var id481 = charIDToTypeID("RGBC");
desc90.putObject(charIDToTypeID("Clr "), id481, desc91);
desc89.putObject(charIDToTypeID("Type"), stringIDToTypeID("solidColorLayer"), desc90);
desc88.putObject(charIDToTypeID("Usng"), stringIDToTypeID("contentLayer"), desc89);
executeAction(charIDToTypeID("Mk  "), desc88, DialogModes.NO);

myPathItem.remove();
}

DrawShape([100, 100, 50,150, 150,50], [100, 200], [200, 200], [200, 100]);

Yes, this would definitely do the job. Thank you r-bin.
