AS3 2D array initialization

Question

What is wrong with this Array Initialization I am getting syntax errors This class hold levels. I cant figure out why its not working. Previously i used to intialize 2d arrays by first declaring an array of certain length then assigning arrays to the elemnets of main array.But when i used this method i am not getting it right

package  {

public class Levels {

    public var Level1:Array = new Array();
    public var Level2:Array = new Array();
    public var Level3:Array = new Array();
    public var Level4:Array = new Array();
    public var Level5:Array = new Array();
    public var Level6:Array = new Array();

    public function Levels() {
        Level1[] =((1,1,1,1,1,1,1,1),
                   (0,1,1,1,1,1,1,0),
                   (0,0,1,1,1,1,0,0),
                   (0,0,1,1,1,1,0,0),
                   (1,1,1,1,1,1,1,1));
        Level2[] =((1,1,1,1,1,1,1,1),
                   (0,1,1,1,1,1,1,0),
                   (0,0,1,1,1,1,0,0),
                   (0,0,1,1,1,1,0,0),
                   (1,1,1,1,1,1,1,1));
        Level3[] = ((1,1,1,1,1,1,1,1),
                   (0,1,1,1,1,1,1,0),
                   (0,0,1,1,1,1,0,0),
                   (0,0,1,1,1,1,0,0),
                   (1,1,1,1,1,1,1,1));
        Level4[]= ((1,1,1,1,1,1,1,1),
                   (0,1,1,1,1,1,1,0),
                   (0,0,1,1,1,1,0,0),
                   (0,0,1,1,1,1,0,0),
                   (1,1,1,1,1,1,1,1));
        Level4[]= ((1,1,1,1,1,1,1,1),
                   (0,1,1,1,1,1,1,0),
                   (0,0,1,1,1,1,0,0),
                   (0,0,1,1,1,1,0,0),
                   (1,1,1,1,1,1,1,1));
        Level5[]= ((1,1,1,1,1,1,1,1),
                   (0,1,1,1,1,1,1,0),
                   (0,0,1,1,1,1,0,0),
                   (0,0,1,1,1,1,0,0),
                   (1,1,1,1,1,1,1,1));
        Level6[]= ((1,1,1,1,1,1,1,1),
                   (0,1,1,1,1,1,1,0),
                   (0,0,1,1,1,1,0,0),
                   (0,0,1,1,1,1,0,0),
                   (1,1,1,1,1,1,1,1));
    }

}

}

Remove square brackets from assignment, and replace round brackets with square brackets on the right side of assignment. Level1 = [[1,1,1,1,1,1,1,1],[0,1,1,1,1,1,1,0],...]; — Vesper

@Vesper only remoeing square brackets worked Level1 = ((1,1,..),(0,1,..)) — user3536228

Your code looks like PHP or some that kind of language - Action Script Array has different approach. You can either use what @Vesper said:

Level1 = [ // array
    [1, 1, 0, 1], // first element, child array
    [0, 0, 0, 0], // second element, child array
    [0, 1, 1, 1]
];

Or you can use push:

Level1.push([0, 1, 0, 1]); // first element, child array
Level1.push([1, 1, 1, 1]); // second element, child array

And just to mention, if you want to use brackets to get/set element of the array, you must provide index:

Level1[0] = [0, 0, 0]; // set first element
Level1[1] = [1, 1, 1]; // set second element
trace(Level[2]); // throws error in your case as there is no such element
