代码结构

详细代码结构如果需要请到github查看

蛇蛇目前：{{snakes.length}}米长 选择游戏难度 简单模式 正常模式 困难模式 地狱模式 开始游戏 游戏结束 您的蛇蛇达到了{{snakes.length}}米 再次挑战 重选难度 export default { data() { return { blocks: [], // 板块 worms: [], // 虫子 snakes: [0, 1, 2, 3], // 蛇身 direction: "right", // 蛇移动方向 }; }, onLoad() { this.initGame(); }, methods: { initGame() { this.blocks = new Array(100).fill(0); // 生成100个地面板块 this.worms = [Math.floor(Math.random() * 96) + 4]; // 随机生成虫子 this.snakes = [0, 1, 2, 3]; // 初始化蛇身位置 } }}渲染蛇身

蛇身的渲染根据snakes来匹配地面板块的索引 修改对应的背景图来渲染蛇身

import worm from "worm.png";import snakeBody from "snake_body.png";import snakeHead from "snake_head.png";import snakeTail from "snake_tail.png";import polluteBlock from "pollute.png";import wormBoom from "worm_4.png";export default { methods: { bg(type, index) { let bg = ""; switch (type) { case 0: // 地板 bg = "unset"; break; case 1: // 虫子 if (this.boom) { bg = `url(${wormBoom})`; } else { bg = `url(${worm})`; } break; case 2: // 蛇 let head = this.snakes[this.snakes.length - 1]; let tail = this.snakes[0]; if (index === head) { bg = `url(${snakeHead})`; } else if (index === tail) { bg = `url(${snakeTail})`; } else { bg = `url(${snakeBody})`; } break; case 3: // 污染的地块 bg = `url(${polluteBlock})`; break; } return bg; }, }}控制蛇的方向

通过监听键盘按键事件和手势来控制蛇的方向
