Return Array from function?

[bangers]

Hi,

I am having some problems with arrays, objects, and functions. I have a function that constructs an array of point objects. Here is a simple version of the function:

function makePoints(num);
  pointList = new Array(num); 
  point = new Object();
  for (j=1; j<=num; j++){
    point.x = j;
    point.y = j;
    pointList[j] = point;
  }
  return pointList;
}

I am calling the function like this:

myPoints = makePoints(3);

I would expect the results to be:

myPoints[1].x:1
myPoints[1].y:1
myPoints[2].x:2
myPoints[2].y:2
myPoints[3].x:3
myPoints[3].y:3

But instead I get:

myPoints[1].x:3
myPoints[1].y:3
myPoints[2].x:3
myPoints[2].y:3
myPoints[3].x:3
myPoints[3].y:3

Where am I going wrong? Is it possible to pass an array back as the result of a function?

I can see other ways to do this. But I would really like to be able to do it in this way. Can anyone help?

Thanks

You'er not creating a class of point objects, you're recreating a single point object every time through the loop.

function point (j) {
    this.x = j;
    this.y = j;
}
function makePoints (num) {
    var j = new Number();
    pointList = new Array(num);
    for (j=1; j<=num; j++) {
        pointList[j] = new point(j);
    }
    return pointList;
}
myPoints = new Array;
myPoints = makePoints(3);
var j = new Number();
for (j=1; j < myPoints.length; j++) {
    trace ("myPoints["+j+"].x,myPoints["+j+"].x = " + myPoints[j].x + ", " + myPoints[j].y);
}
