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>
