Passing Arrays with Objects to a function

1

I am working with the 3D engine in one of the tutorials, but I am expanding one of the functions to have an Array with objects as a parameter:

backAndForthAndSideToSide = function (pointsArray:Array) {
	var screenPoints = new Array();
	for (var i = 0; i<pointsArray.length; i++) {
		var thisPoint = pointsArray*;
		if (direction == "left") {
			thisPoint.y -= speed;
			if (i == pointsArray.length-1 && thisPoint.y<=-150) {
				direction = "backward";
			}
		} else if (direction == "backward") {
			thisPoint.z += speed;
			if (i == pointsArray.length-1 && thisPoint.z>=150) {
				direction = "right";
			}
		} else if (direction == "right") {
			thisPoint.y += speed;
			if (i == pointsArray.length-1 && thisPoint.y>=150) {
				direction = "forward";
			}
		} else if (direction == "forward") {
			thisPoint.z -= speed;
			if (i == pointsArray.length-1 && thisPoint.z<=-150) {
				direction = "left";
			}
		}

With the array:

MakeA3DPoint = function (x, y, z) {
	var point = new Object();
	point.x = x;
	point.y = y;
	point.z = z;
	return point;
};
MakeBox = function (Num, Width, Depth, Height) {
	_root.createEmptyMovieClip("box"+Num,Num);
	Points = new Array();
	Points = [[-Width/2, -Height/2, -Depth/2], [Width/2, -Height/2, -Depth/2], [Width/2, -Height/2, Depth/2], [-Width/2, -Height/2, Depth/2], [-Width/2, Height/2, -Depth/2], [Width/2, Height/2, -Depth/2], [Width/2, Height/2, Depth/2], [-Width/2, Height/2, Depth/2]];
	for (i=0; i<Points.length; i++) {
		Points* = MakeA3DPoint(Points*[0], Points*[1], Points*[2]);
	}
	return Points;
	
};
this.pointsArray2 = _root.MakeBox(2,80, 80, 80);
box.onEnterFrame = backAndForthAndSideToSide(pointsArray2);

Thank you to any insight you can provide,
