Question

I was wondering if there was a better way to create a large 2D array and populate it with a single item with AS3? This is a quick example what I’m currently doing:

private var array:Array = [[1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1],
                           [1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1],
                           [1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1],
                           [1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1],
                           [1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1]];

But there has to be a more functional way! Thanks in advance.

Can’t you just use a ‘traditional’ loop to fill it? Something as simple as

var numCols:uint = 10,
    numRows:uint = 10,
    fillValue:uint = 1,
    array:Array = new Array(),
    i:uint,
    j: uint;

for (i = 0; i < numRows; i++) {
  array.push(new Array());
  for (j = 0; j < numCols; j++) {
    array[i].push(fillValue);
  }
}
