Ever got sick of creating 2 dimensional arrays? Wanted a class to do it for you?

Try this class I whacked together in a flurry of inspiration (I’m kidding myself - give me a break).

dynamic class Grid extends Array{
  private var vw:uint
  private var vh:uint

  public function Grid(vx:uint, vy:uint)
  {
    vw = vx;
    vh = vy;    

    for (var i:int=0; i< vx; i++)
    {
      this[i] = new Array(vy);
    }
  }

  public function get width():uint
  {
    return vw;
  }
  public function get height():uint
  {
    return vh;
  }
}

What this class does at the moment is relatively simple.

You simply declare a variable as a new Grid like so

var myGrid:Grid = new Grid(10,10);

That will create a 2 dimensional array 10×10. You can then reference it as you’d do a normal 2 dimensional array:

trace(myGrid[4][1]);

And that’s the end of my trivial actionscript pursuits. Enjoy!
