Getting an Array from a multi-dimentional Array within a Function

Don't know how to explain it but here, firstly, I can't get past. Also had this problem with another thing I was trying.

ReferenceError: Error #1056: Cannot create property 0 on Number.

I googled and found out about automatically declare stage instances, that was fine, I had the box checked.

Basically, it is failing at even the simplest. I have this function:

function getInfoOf(i) { // enemy count, info count
    var _info:Array = new Array(3, 6); 
    // 0 is you
    _info[0,Const.MAXHP] = 500;
    _info[0,Const.CURRENTHP] = 500;
    _info[0,Const.LEVEL] = 5;
    _info[0,Const.EXP] = 5500;
    _info[0,Const.NAME] = "You";
    _info[0,Const.LINKEDMC] = "NONE";
    // then a few more _info's.
}

Then, trying everything to get it to work, I stripped it so no returns. So in the code, in the init() part of the project (only called once), have getInfoOf(0), and tried any other numbers. I recieve that error, and cannot for the life of me figure out whats wrong (I have also tested the "Const"'s. they are integers, and I have tested using numbers in  place of those. Still same error, it only goes away when I don't call the function at all.

Any help would be greatly appreciated.

Thanks.

Correct answer kglad
var theTestRow:Object = getInfo(2);
trace(theTestRow[4]); // 34
function getInfo(i):Object {
    var info:Object = new Object(); 
    info[0] = [2,4,7,3,8,3]; 
    info[1] = [23,53,76,32,68,74]; 
    info[2] = [0,896,45,355,34,35]; 
    return info;
}

No matter what I tried, could not get a 2 dimensional array to work. I tried 1 dimensional and no problem there. So, either could have done multiplication and a 1 directional array, or this, which works no problem.

Thanks.


again, to access an array element (eg, the last), use:

_info[2][5]="whatever";

NOT

    info[0,5] = 0;

i'm not sure what you're trying to do but, if you're trying to create a 2d (3x6) array, among the ways to do that is:

var _info:Array=new Array(3);

for(var i:int=0;i<_info.length;i++{

_info=new Array(6);

}

then to access an array element (eg, the last), use:

_info[2][5]="whatever";

I don't know whats wrong here. I tried to get it to work on the project, still same exact error. So, I tried it on a entirely new project, and still get the exact same error. So I also put in a new function to test with no array.

stop();
function getInfoOf2():void {
    var blah = "testwat";
    trace(blah);
    return;
}
function getInfoOf():void {
    
    var info:Array=new Array(3);
    for(var i:int=0; i<info.length; i++) {
        info=new Array(6);
    }    
    
    // 0 
    info[0,0] = 500;
    info[0,1] = 500;
    info[0,2] = 5;
    info[0,3] = 5500;
    info[0,4] = 0;
    info[0,5] = 0;
    
    return;
}
this.getInfoOf2();
this.getInfoOf();

the function still fails, but the first function doesn't.

testwat
ReferenceError: Error #1056: Cannot create property 0 on Number.
    at Untitled_fla::MainTimeline/getInfoOf()
    at Untitled_fla::MainTimeline/frame1()

any ideas, I did a few traces, that message appears at the first info[0][0].

Thanks.
