微信小程序游戏类demo：经典扫雷，绘制一张 10*10 的地图

柿霖不是林

undefined不会玩扫雷 作者：jixiaod 微信小程序这几天很火，9号正式发布，今天19号过了10天，到现在略有降温的趋势。个大厂商对微信小程序的态度很不看好，最激进的要数[罗辑思维]，直接下架了自己的[得到APP]。滴滴、京东等APP也只保留了最精简的功能，某些担心过于完善的功能会抢夺APP本身的用户。不过这也印证了小程序的初衷，小而精、用完即走。（并不否认腾讯微信平台确实流氓的事实） PS：墨迹天气也开发了微信小程序版本，并且在1月9号第一时间发布，欢迎使用。 作为技术人员，怎能不亲手试试小程序开发呢？扫雷 Minesweeper 实现思路： 如果不了解扫雷的游戏规则，请自行 Google 绘制一张 10*10 的地图，并且标注地雷和非地雷，并且需要用数字表示每个点周围地雷的数量 用 mineMap[x][y] 表示一个点位 mineMap[x][y] < 0 (代码中 == -1) 初始状态 0 < mineMap[x][y] < 9 该点周围地雷的数量 mineMap[x][y] == 9 表示该点是地雷 mineMap[x][y] > 9 （代码中 == 10）表示该点插旗 如何跑起来？ 下载&安装微信小程序开发工具 配置 wechat-app-minesweeper 代码目录到开发工具即可 玩法 需要注意的是，由于没有鼠标右键标记Flag，简单做了 Flag 切换，开启后，方可标记Flag 最初的想法是通过 tap 和 longtap 来区分扫雷和Flag，但是开发工具不能区分这俩个事件，只能作罢 [HTML] 纯文本查看 复制代码 //index.js //获取应用实例 var app = getApp() Page({ data: { mineMap: {}, timesGo: 0, minesLeft: 0 }, mineMap: {}, mineMapMapping: {}, rowCount: 10, colCount: 10, mineCount: 10, minMineCount: 10, maxMineCount: 20, minesLeft: 0, timesGo: 0, timeInterval: null, flagOn: false, flags: 0, endOfTheGame: false, safeMinesGo: 0, onLoad: function() { this.setData({ minesLeft: 0, timesGo: 0 });
