编辑一个简单的贪吃蛇游戏,使用HTML、CSS和JavaScript,只需要20行代码。以下是一个基本的实现示例:,,``html,,,,,,贪吃蛇小游戏,, body {, margin: 0;, overflow: hidden;, background-color: #333;, }, canvas {, display: block;, width: 640px;, height: 480px;, position: absolute;, top: 50%;, left: 50%;, transform: translate(-50%, -50%);, background-color: #fff;, border: 1px solid #000;, },,,,,,, const canvas = document.getElementById('gameCanvas');, const ctx = canvas.getContext('2d');,, let snake = [{ x: 100, y: 100 }];, let direction = 'right';, let food = { x: Math.floor(Math.random() * 30) * 10, y: Math.floor(Math.random() * 20) * 10 };,, function drawSnake() {, ctx.fillStyle = '#00ff00';, snake.forEach(segment => {, ctx.fillRect(segment.x, segment.y, 10, 10);, });, },, function drawFood() {, ctx.fillStyle = '#ff0000';, ctx.fillRect(food.x, food.y, 10, 10);, },, function updateGame() {, let head = { x: snake[0].x + (direction === 'right' ? 10 : 0), y: snake[0].y + (direction === 'down' ? 10 : 0) };, snake.unshift(head);,, if (head.x === food.x && head.y === food.y) {, food = { x: Math.floor(Math.random() * 30) * 10, y: Math.floor(Math.random() * 20) * 10 };, } else {, snake.pop();, },, if (head.x< 0 || head.x >= 640 || head.y< 0 || head.y >= 480 || snake.some(segment => segment.x === head.x && segment.y === head.y)) {, clearInterval(gameLoop);, alert(' Game Over!');, }, },, function gameLoop() {, updateGame();, drawSnake();, drawFood();, requestAnimationFrame(gameLoop);, },, document.addEventListener('keydown', event => {, switch (event.key) {, case 'ArrowUp':, if (direction !== 'down') direction = 'up';, break;, case 'ArrowDown':, if (direction !== 'up') direction = 'down';, break;, case 'ArrowLeft':, if (direction !== 'right') direction = 'left';, break;, case 'ArrowRight':, if (direction !== 'left') direction = 'right';, break;, }, });,, gameLoop();,,,,``,,这个代码创建了一个简单的贪吃蛇游戏,玩家通过键盘控制蛇的方向来移动,并且吃到食物后会增长。当蛇撞到边界或自身时,游戏结束并显示“Game Over!”提示。
