1. 创建HTML文件1. 打开一个文本编辑器，例如Notepad++、Sublime Text、Visual Studio Code等。2. 将以下HTML代码复制并粘贴到文本编辑器中：html
2048
Score: 0
3. 将文件保存为 index.html 。2. 创建CSS文件1. 在同一目录下创建一个新的文件，并将以下CSS代码复制并粘贴到该文件中：cssbody {
font-family: Arial, sans-serif;
display: flex;
flex-direction: column;
align-items: center;
justify-content: center;
height: 100vh;
margin: 0;
background-color: #faf8ef;
}
header {
text-align: center;
margin-bottom: 20px;
}
h1 {
font-size: 60px;
margin: 0;
}
button {
padding: 10px 20px;
font-size: 16px;
margin-top: 10px;
cursor: pointer;
}
p {
font-size: 24px;
margin: 10px 0;
}
#grid-container {
width: 460px;
height: 460px;
padding: 20px;
background-color: #bbada0;
border-radius: 10px;
position: relative;
display: grid;
grid-template-columns: repeat(4, 100px);
grid-template-rows: repeat(4, 100px);
gap: 20px;
}
.grid-cell {
width: 100px;
height: 100px;
background-color: #ccc0b3;
border-radius: 6px;
display: flex;
align-items: center;
justify-content: center;
font-size: 24px;
font-weight: bold;
color: #776e65;
}
#gameover {
display: none;
position: absolute;
top: 50%;
left: 50%;
transform: translate(-50%, -50%);
background-color: rgba(0, 0, 0, 0.8);
color: white;
font-size: 48px;
padding: 20px;
border-radius: 10px;
}
2. 将文件保存为 styles.css 。3. 创建JavaScript文件1. 在同一目录下创建一个新的文件，并将以下JavaScript代码复制并粘贴到该文件中：javascriptconst board = Array.from({ length: 4 }, () => Array(4).fill(0));
let score = 0;
document.addEventListener('DOMContentLoaded', () => {
document.getElementById('newGameButton').addEventListener('click', newGame);
document.addEventListener('keydown', handleKeyPress);
newGame();
});
function newGame() {
for (let i = 0; i < 4; i++) {
for (let j = 0; j < 4; j++) {
board[i][j] = 0;
}
}
score = 0;
updateScore();
generateNewNumber();
generateNewNumber();
updateBoard();
document.getElementById('gameover').style.display = 'none';
}
function generateNewNumber() {
let emptyCells = [];
for (let i = 0; i < 4; i++) {
for (let j = 0; j < 4; j++) {
if (board[i][j] === 0) {
emptyCells.push({ x: i, y: j });
}
}
}
if (emptyCells.length === 0) return;
const { x, y } = emptyCells[Math.floor(Math.random() * emptyCells.length)];
board[x][y] = Math.random() < 0.9 ? 2 : 4;
}
function updateBoard() {
for (let i = 0; i < 4; i++) {
for (let j = 0; j < 4; j++) {
const cell = document.getElementById(`grid-cell-${i}-${j}`);
cell.textContent = board[i][j] === 0 ? '' : board[i][j];
cell.style.backgroundColor = getBackgroundColor(board[i][j]);
}
}
}
function getBackgroundColor(value) {
switch (value) {
case 2: return '#eee4da';
case 4: return '#ede0c8';
case 8: return '#f2b179';
case 16: return '#f59563';
case 32: return '#f67c5f';
case 64: return '#f65e3b';
case 128: return '#edcf72';
case 256: return '#edcc61';
case 512: return '#edc850';
case 1024: return '#edc53f';
case 2048: return '#edc22e';
default: return '#cdc1b4';
}
}
function handleKeyPress(event) {
switch (event.key) {
case 'ArrowUp':
moveUp();
break;
case 'ArrowDown':
moveDown();
break;
case 'ArrowLeft':
moveLeft();
break;
case 'ArrowRight':
moveRight();
break;
}
generateNewNumber();
updateBoard();
if (isGameOver()) {
document.getElementById('gameover').style.display = 'block';
}
}
function moveUp() {
for (let j = 0; j < 4; j++) {
let compressed = compress(board.map(row => row[j]));
for (let i = 0; i < 4; i++) {
board[i][j] = compressed[i];
}
}
}
function moveDown() {
for (let j = 0; j < 4; j++) {
let compressed = compress(board.map(row => row[j]).reverse()).reverse();
for (let i = 0; i < 4; i++) {
board[i][j] = compressed[i];
}
}
}
function moveLeft() {
for (let i = 0; i < 4; i++) {
board[i] = compress(board[i]);
}
}
function moveRight() {
for (let i = 0; i < 4; i++) {
board[i] = compress(board[i].reverse()).reverse();
}
}
function compress(row) {
let newRow = row.filter(val => val !== 0);
for (let i = 0; i < newRow.length - 1; i++) {
if (newRow[i] === newRow[i + 1]) {
newRow[i] *= 2;
score += newRow[i];
newRow[i + 1] = 0;
}
}
newRow = newRow.filter(val => val !== 0);
while (newRow.length < 4) {
newRow.push(0);
}
updateScore();
return newRow;
}
function updateScore() {
document.getElementById('score').textContent = score;
}
function isGameOver() {
for (let i = 0; i < 4; i++) {
for (let j = 0; j < 4; j++) {
if (board[i][j] === 0) return false;
if (i < 3 && board[i][j] === board[i + 1][j]) return false;
if (j <3 && board[i][j] === board[i][j + 1]) return false;
}
}
return true;
}
2. 将文件保存为 script.js 。4. 运行游戏1. 确保三个文件（ index.html 、 styles.css 、 script.js ）都位于同一目录下。2. 双击 index.html 文件，它将在默认浏览器中打开。3. 使用键盘上的箭头键来控制游戏。
