Array 2D of data

Hello,
I’m trying to make a 2D array of data :

 var data = new Array();
cards_3[0] = new Array();
cards_3[0]["attack"] = 5;
cards_3[0]["damage"] = 3;

is not work!

how i can create 2D Array or Object in javascript (UnityScript) ?

example :

var[0] {
	attack : 0,
	damage : 0,
},
var[1] {
	attack : 0,
	damage : 0,
}...

thanks.

Arrays use integers for indexing, not strings. There may be UnityScript quirks to handle array indexing that I don’t know about, in that case you’ll have to wait for someone more experienced in UnityScript to come along.

To create a 2D array:

var my2D = new int[10, 2]; // my2D references 10*2 integers
my2D[0, 0] = 5;
my2D[0, 1] = 3;
my2D[4, 1] = 8; // Set fifth column, second row to 8

You could create a class that contain your data and use a normal array.

class Attack
{
    var type : int;
    var damage : int;

    function Attack(type : int, damage : int)
    {
        this.type = type;
        this.damage = damage;
    }

    function ToString()
    {
        return "Attack: " + type + ", " + damage;
    }
}

var attacks : Attack[];
attacks = new Attack[2];
attacks[0] = new Attack(5, 3);
attacks[1] = new Attack(5, 10);

If you need to refer to variables via strings, I guess you could have an array of Dictionaries, but in that case I’d recommend you create a dedicated class to handle that.
