Code	/********************************************************* * My version of 2048 * See http://gabrielecirulli.github.io/2048/ * * Use the arrow keys to move the tiles. * If you press left, all the tiles move * to the left as far as they can go. * Any tile that hits another tile with the same * number merges with it and their values combine. * The aim of the game is to get a tile with the number 2048 * on it (which is 2 to the power of 11, so 11 merges). * * Have a look at my Khan Academy themed version: * https://www.khanacademy.org/cs/khan-academy-2048/5241208742871040 * * To do * - Animate moves *********************************************************/ var DIMENSIONS = 4; var ANIMATE_TIME = 12; var BACKGROUND = color(250, 248, 239); var TILE = color(204, 192, 179); var GRID = color(187, 173, 160); var TEXTCOL = color(119, 110, 101); var score = 0; var turns = 0; var animation = 0; var lastTile = false; var result = false; // Get grid size and position for drawing var border = 50; var gridBorder = 8; var gridSize = width - border; var tileSize = floor((gridSize - gridBorder) / DIMENSIONS) - gridBorder; var halfTile = tileSize / 2; gridSize = DIMENSIONS (tileSize + gridBorder) + gridBorder; border = width - gridSize; var gx = gridBorder + border / 2; var gy = gridBorder + border - 8; var fontSize = tileSize * 0.7; var myFont = createFont("Sans", fontSize); // Create an 2D array of 0s var createGrid = function() { var grid = []; for (var x = 0; x < DIMENSIONS; x++) { var row = []; for (var y = 0; y < DIMENSIONS; y++) { row.push(0); } grid.push(row); } return grid; }; // Return an array of positions where the grid is 0 var getEmptyPositions = function(grid) { var emptyPositions = []; for (var x = 0; x < DIMENSIONS; x++) { for (var y = 0; y < DIMENSIONS; y++) { if (grid[x][y] === 0) { emptyPositions.push({ x: x, y: y }); } } } return emptyPositions; }; // Check whether it is possible to merge tiles without sliding // Used to test whether player has lost the game var possibleMerges = function(grid) { for (var x = 0; x < DIMENSIONS; x++) { for (var y = 0; y < DIMENSIONS; y++) { if (x > 0 && grid[x][y] === grid[x - 1][y]) { return true; } if (y > 0 && grid[x][y] === grid[x][y - 1]) { return true; } } } return false; }; // Add a tile to a random empty position // If no empty positions then end game var addRandomTile = function(grid) { var emptyPositions = getEmptyPositions(grid); var n = floor(random(emptyPositions.length)); var position = emptyPositions[n]; if (random() < 0.9) { grid[position.x][position.y] = 1; } else { grid[position.x][position.y] = 2; } lastTile = position; animation = ANIMATE_TIME; if (emptyPositions.length === 1 && !possibleMerges(grid)) { result = "lose"; } }; // Flip the grid vertically var flipGrid = function(grid) { var newGrid = []; for (var y = 0; y < DIMENSIONS; y++) { newGrid.push(grid[DIMENSIONS - y - 1]); } return newGrid; }; // Move grid through 90 degrees clockwise or anti-clockwise if reverse is true var rotateGrid = function(grid, reverse) { var newGrid = []; for (var y = 0; y < DIMENSIONS; y++) { var row = []; for (var x = 0; x < DIMENSIONS; x++) { var nx = reverse ? x : DIMENSIONS - x - 1; var ny = reverse ?
