微信开发之2048游戏

在这篇微信小程序开发教程中，我们将介绍如何使用微信小程序开发2048小游戏。

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 ? &#39;won&#39; : &#39;over&#39;) : &#39;&#39;}}">
              <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

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)
            });
