Initial value question...

var originX : int = 10;
var originY : int = 10;
var isAltColumn : boolean = false;

function Start () {
	for (var i : int = 0; i < 24; i++) {
	Debug.Log ("Origing Y: " + originY);	//	Returns: 25,0,10,0,10, etc...  Why 25 as the initial value?
		for (var j : int = 0; j < 12; j++) {
			var hex = new VectorLine ("Hex", new Vector2[12], null, 1.0);
			Vector.MakeCircleInLine (hex, Vector2(originX, originY), 25);
			Vector.DrawLine (hex);
			originY += 43.305;
		}
		originY = (isAltColumn) ? 10 : 0;
		isAltColumn = !isAltColumn;
		originX += 38;
	}
