微信开发之2048游戏

本文主要分为两个部分，小程序主体部分及小游戏页面部分

一、小程序主体部分

一个小程序主体部分由三个文件组成，必须放在项目的根目录，如下：

1. 小程序逻辑

App({  onLaunch: function() {     // Do something initial when launch.  },  onShow: function() {      // Do something when show.  },  onHide: function() {      // Do something when hide.  },  globalData: 'I am global data'})

2. 小程序公共设置

主要注册一个页面，即2048游戏主页

{  "pages":[    "pages/index/index"      ],  "window":{    "navigationBarBackgroundColor":"#ffffff",    "navigationBarTextStyle":"#1AAD16",    "navigationBarTitleText":"2048游戏",    "backgroundColor":"#eeeeee",    "backgroundTextStyle":"light"  },  "networkTimeout": {    "request": 10000,    "downloadFile": 10000  },  "debug": false}

二、小游戏页面部分

2048游戏小程序页面主要由以下文件组成。

1. 页面结构

其页面结构代码如下

<view class="container">  <view class="game-body">    <loading hidden="{{hidden}}">        加载中...    </loading>    <view class="heading">          <text class="title">2048</text>          <view class="scores-container">            <view class="score-container">{{score}}</view>              <view class="best-container">{{highscore}}</view>          </view>    </view>    <view class="above-game">          <text class="game-intro">你能拿到2048吗？</text>          <text class="restart-button" bindtap="restart">新游戏</text>    </view>    <view class="game-container">        <view class="game-message game-{{over ? (win ? 'won' : 'over') : ''}}">              <text class="over-msg">{{overMsg}}</text>              <view class="lower">                <!-- <text class="keep-playing-button">继续</text> -->                  <text class="retry-button" bindtap="restart">再试一次</text>            </view>        </view>        <view class="grid-container" bindtouchstart="touchStart" bindtouchmove="touchMove" bindtouchend="touchEnd">            <view wx:for="{{grids}}" wx:for-index="rowIdx" wx:for-item="row" class="grid-row">                  <view wx:for="{{row}}" wx:for-index="colIdx" wx:for-item="cell" class="grid-cell">                      <view class="tile tile-{{cell.value}}">                          <view wx:if="{{cell}}" class="tile-inner">                              {{cell.value}}                          </view>                      </view>                  </view>            </view>        </view>      </view>      <!-- <view class="game-explanation">      <view class="important">如何开始：</view> 手指上下左右滑动    </view> --></view></view>

2. 样式表

样式代码如下所示

   line-height: 30px !important;    margin-top: 90px !important;  }  .game-message .lower {    margin-top: 30px !important;  }}

3、 页面逻辑处理

var app = getApp();var Grid = require('./grid.js');var Tile = require('./tile.js');var GameManager = require('./game_manager.js');var config = {    data: {        hidden: false,        // 游戏数据可以通过参数控制        grids: [],        over: false,        win: false,        score: 0,        highscore: 0,        overMsg: '游戏结束'    },    onLoad: function() {        this.GameManager = new GameManager(4);        this.setData({            grids: this.GameManager.setup(),            highscore: wx.getStorageSync('highscore') || 0        });    },    onReady: function() {        var that = this;        // 页面渲染完毕隐藏loading        that.setData({            hidden: true        });    },    onShow: function() {        // 页面展示    },    onHide: function() {        // 页面隐藏    },    onUnload: function() {        // 页面关闭    },    // 更新视图数据    updateView: function(data) {        // 游戏结束        if(data.over){            data.overMsg = '游戏结束';        }        // 获胜        if(data.win){            data.overMsg = '恭喜';        }        this.setData(data);    },    // 重新开始    restart: function() {        this.updateView({            grids: this.GameManager.restart(),            over: false,            won: false,            score: 0        });    },    touchStartClienX: 0,    touchStartClientY: 0,    touchEndClientX: 0,    touchEndClientY: 0,    isMultiple: false, // 多手指操作    touchStart: function(events) {        // 多指操作        this.isMultiple = events.touches.length > 1;        if (this.isMultiple) {            return;        }        var touch = events.touches[0];        this.touchStartClientX = touch.clientX;        this.touchStartClientY = touch.clientY;    },    touchMove: function(events) {        var touch = events.touches[0];        this.touchEndClientX = touch.clientX;        this.touchEndClientY = touch.clientY;    },    touchEnd: function(events) {        if (this.isMultiple) {            return;        }        var dx = this.touchEndClientX - this.touchStartClientX;        var absDx = Math.abs(dx);        var dy = this.touchEndClientY - this.touchStartClientY;        var absDy = Math.abs(dy);        if (Math.max(absDx, absDy) > 10) {            var direction = absDx > absDy ? (dx > 0 ? 1 : 3) : (dy > 0 ? 2 : 0);            var data = this.GameManager.move(direction) || {                grids: this.data.grids,                over: this.data.over,                won: this.data.won,                score: this.data.score            };            var highscore = wx.getStorageSync('highscore') || 0;            if(data.score > highscore){                wx.setStorageSync('highscore', data.score);            }            this.updateView({                grids: data.grids,                over: data.over,                won: data.won,                score: data.score,                highscore: Math.max(highscore, data.score)            });        }    }};Page(config);

除此之外，还引用了原Web版2048游戏的一些js文件。
