Chapter 3, Exercise 2 – Experimental Board Layouts

Now that you can make createLayout build a different grid pattern, write code to generate an entirely new layout. For example, you could draw only every alternate column or build a more creative layout.

One simple change is to add spaces between bubbles by changing createLayout in board.js:

var createLayout = function(){
  var rows = [];
  for(var i=0;i<NUM_ROWS;i++){
    var row = [];
    var startCol = i%2 == 0 ? 1 : 0;
    for(var j=startCol;j<NUM_COLS;j+=3){
      var bubble = BubbleShoot.Bubble.create(i,j);
      row[j] = bubble;
    };
    rows.push(row);
  };
  return rows;
};

Again, this doesn’t look like it’s going to make the game particularly easy.
