Adding extra levels

Now that the game is looking better, we can add some more content in to it. Luckily the jagged array we created earlier easily supports adding more levels. Levels can be any size, even with variable column heights per row. Double-click on the Sokoban script in the Project panel and switch over to MonoDevelop. Find levels array and modify it to be as follows:

  // Create the top array, this will store the level arrays
  int[][][] levels = 
  {
    // Create the level array, this will store the row array
    new int [][] {
    // Create all row array, these will store column data
    new int[] {1,1,1,1,1,1,1,1},
    new int[] {1,0,0,1,0,0,0,1},
    new int[] {1,0,3,3,0,3,0,1},
    new int[] {1,0,0,1,0,1,0,1},
    new int[] {1,0,0,1,3,1,0,1},
    new int[] {1,0,0,2,2,2,2,1},
    new int[] {1,0,0,1,0,4,1,1},
    new int[] {1,1,1,1,1,1,1,1}
  },
  // Create a new level
  new int [][] {
    new int[] {1,1,1,1,0,0,0,0},
    new int[] {1,0,0,1,1,1,1,1},
    new int[] {1,0,2,0...
