摘要：const canvas = document.getElementById('gameCanvas');const ctx = canvas.getContext('2d');// 加载玩家图片const playerImage = new Image;pl
1、安装cursor：略过
2、登录cursor：略过
3、在右侧chat输入：用JS创建平台跳跃游戏，点击send
4、生成代码，并保存代码
const canvas = document.getElementById('gameCanvas');const ctx = canvas.getContext('2d');// 加载玩家图片const playerImage = new Image;playerImage.src = 'player.png'; // 请确保在同一目录下有 player.png 文件// 玩家属性const player = {x: 100,y: 200,width: 30,height: 30,speed: 5,jumpForce: 12,gravity: 0.5,velocityY: 0,isJumping: false};// 平台数组const platforms = [{ x: 0, y: 350, width: 800, height: 50 }, // 地面{ x: 300, y: 250, width: 200, height: 20 }, // 平台1{ x: 100, y: 150, width: 200, height: 20 }, // 平台2{ x: 500, y: 200, width: 200, height: 20 } // 平台3];// 键盘控制const keys = {left: false,right: false,up: false};// 事件监听document.addEventListener('keydown', (e) => {if (e.key === 'ArrowLeft') keys.left = true;if (e.key === 'ArrowRight') keys.right = true;if (e.key === 'ArrowUp' && !player.isJumping) {keys.up = true;player.isJumping = true;player.velocityY = -player.jumpForce;}});document.addEventListener('keyup', (e) => {if (e.key === 'ArrowLeft') keys.left = false;if (e.key === 'ArrowRight') keys.right = false;if (e.key === 'ArrowUp') keys.up = false;});// 碰撞检测function checkCollision(rect1, rect2) {return rect1.x
rect2.x &&rect1.y
rect2.y;}// 更新游戏状态function update {// 水平移动if (keys.left) player.x -= player.speed;if (keys.right) player.x += player.speed;// 应用重力player.velocityY += player.gravity;player.y += player.velocityY;// 检查与平台的碰撞player.isJumping = true;for (let platform of platforms) {if (checkCollision(player, platform)) {if (player.velocityY > 0) {player.y = platform.y - player.height;player.velocityY = 0;player.isJumping = false;}}}// 边界检查if (player.x
canvas.width) player.x = canvas.width - player.width;if (player.y + player.height > canvas.height) {player.y = canvas.height - player.height;player.velocityY = 0;player.isJumping = false;}}// 绘制游戏画面function draw {// 清空画布ctx.clearRect(0, 0, canvas.width, canvas.height);// 绘制玩家ctx.fillStyle = '#FF0000';ctx.fillRect(player.x, player.y, player.width, player.height);// 绘制平台ctx.fillStyle = '#00FF00';platforms.forEach(platform => {ctx.fillRect(platform.x, platform.y, platform.width, platform.height);});}// 游戏主循环function gameLoop {update;draw;requestAnimationFrame(gameLoop);}// 开始游戏gameLoop; 5、运行index.html
总结：跳跃反应流畅
