[F8] Adding a multidimensional array together?

I've got a m.d array which I am filling with values. Is there a quick way to add up every item? Maybe a function built in?

Code:

---

var p:Array = [3, 4, 5, [5, 3, 1, [2, 3], 3], 34];
function addValues(array:Array):Number {
        var toReturn:Number = 0;
        function getNums(array:Array) {
                for (var z in array) {
                        (array[z] instanceof Array) ? getNums(array[z]) : (typeof(array[z]) == "number") ? toReturn += array[z] : null;
                }
        }
        getNums(array);
        return toReturn;
}
trace(addValues(p))

---

Can I copy and paste this code or do I have to modify it??

copy and paste the function, the array "p" is just there as an example.

It's not working - I get an 'undefined' error.

My array is like this:

array[0][0] = 1
array[0][1] = 2
array[3][4] = 5

etc...

it is you code that is at fault, not mine.

you can not do array[0][0] = 0 unless it is defined before hand, i.e.

if you do :

Code:

---

var array:Array = new Array();
array[0][0] = 0;
trace(array[0][0]);

---

it will trace undefined, you have to do it like this:

Code:

---

var array:Array = new Array();
array[0] = [1];
trace(array[0][0]);

---

or a similar method,

HTH,

This is what the array is done with:

Code:

---

aWeek = new Array();
for(i=0;i<7;i++){
    aWeek[i] = new Array();
    for(ii=0;ii<12;ii++){
        aWeek[i][ii] = "";
    }
}

---

I thought this would be better - or at least similar to what you are advising me to do:

Code:

---

function addArrays(array, v){
        var arr1:Number = array.length;
        for(i=0;i<arr1;i++){
    var arr2:Number = array[i].length;
    for(ii=0;ii<12;ii++){
        v = v+parseInt(array[i][ii]);
                //trace(v);
    }
}
}

---

But this does not show anything:

Code:

---

addArrays(wProtein, vProtein);
trace(vProtein);

---

It just shows vProtein as 0, so it's not getting updated. ... Why could that be?

as i said, you have to define the nested array first, this would be the right way to set up your array:

Code:

---

var aWeek:Array = new Array();
for(var z = 0; z<7; z++){
    var temp:Array = new Array();
    for(var j = 0; j<12; j++){
        temp.push("");
    }
    aWeek.push(temp);
}

Thanks for your help so far, you've put me in the right direction. This is how I solved this:

Code:

---

vProtein = addArrays(wProtein, vProtein);

---

What I did was to change the addArray function so it would return the v value and then I put that into vProtein. I was getting a weird error at first, the values were adding on and accumulating so I changed the addArray function:

Code:

---

function addArrays(array, v){
        v=0;  <-------------------------- I added this line
        var arr1:Number = array.length;
        for(i=0;i<arr1;i++){
    var arr2:Number = array[i].length;
    for(ii=0;ii<12;ii++){
        v = v+parseInt(array[i][ii]);
                //trace(v);
    }
}
return v;
}

---

So now the array adds to v from scratch and everything works great. Maybe this will have an unspotted error but to be honest I have tested it and it seems fine!

Thanks again for making me think harder!

thats cool, but you dont need the "v" parameter in the addArrays() function.

glad it works,
