推箱子游戏是老游戏了， 网上有各种各样的版本， 说下推箱子游戏的简单实现，以及我找到的一些参考视频和实例；
如下是效果图：
这个拖箱子游戏做了移动端的适配， 我使用了zepto的touch模块， 通过手指滑动屏幕就可以控制乌龟走不同的方向；
因为推箱子这个游戏比较简单， 直接用了过程式的方式写代码， 模块也就是两个View 和 Model， 剩下就是用户的事件Controller， 用户每一次按下键盘的方向键都会改变数据模型的数据，然后重新生成游戏的静态html， 然后用innerHTML方式插入到界面， 自动生成DOM节点；
游戏的关卡模型就是数据， 我把每一关的数据分为三块：
地图数据，二维数组（地图数据包括板砖， 箱子要去的目标位置， 空白的位置）
箱子数据，一维数组（箱子的初始位置）
小乌龟的数据，json对象
每一个关卡都有对应的游戏关卡数据， 模拟的数据如下：
level: [ { //0是空的地图 //1是板砖 //3是目标点 state:[ [0,0,1,1,1,0,0,0,0], [0,1,1,3,3,1,0,0,0], [0,1,0,0,0,0,1,0,0], [0,1,0,0,0,0,1,0,0], [0,1,1,1,1,1,1,0,0] ], person: {x : 2, y : 2}, box: [{x:3, y : 2},{x:4,y:2}] }, //第二关 { //0是空的地图 //1是板砖 //3是目标点 state:[ [0,1,1,1,1,1,0,0], [0,1,0,0,1,1,1,0], [0,1,0,0,0,0,1,0], [1,1,1,0,1,0,1,1], [1,3,1,0,1,0,0,1], [1,3,0,0,0,1,0,1], [1,3,0,0,0,0,0,1], [1,1,1,1,1,1,1,1] ], person: {x : 2, y : 2}, box: [{x:3, y : 2}, {x:2,y:5} ,{x:5, y:6}] /* box : [ {x:3, y : 1}, {x:4, y : 1}, {x:4, y : 2}, {x:5, y : 5} ] */ }, //第三关 { //0是空的地图 //1是板砖 //3是目标点 state:[ [0,0,0,1,1,1,1,1,1,0], [0,1,1,1,0,0,0,0,1,0], [1,1,3,0,0,1,1,0,1,1], [1,3,3,0,0,0,0,0,0,1], [1,3,3,0,0,0,0,0,1,1], [1,1,1,1,1,1,0,0,1,0], [0,0,0,0,0,1,1,1,1,0] ], person: {x : 8, y : 3}, box: [{x:4, y : 2}, {x:3,y:3} ,{x:4, y:4},{x:5, y:3},{x:6, y:4}] }, //第四关 { //0是空的地图 //1是板砖 //3是目标点 state:[ [0,1,1,1,1,1,1,1,0,0], [0,1,0,0,0,0,0,1,1,1], [1,1,0,1,1,1,0,0,0,1], [1,0,0,0,0,0,0,0,0,1], [1,0,3,3,1,0,0,0,1,1], [1,1,3,3,1,0,0,0,1,0], [0,1,1,1,1,1,1,1,1,0] ], person: {x : 2, y : 3}, box: [{x:2, y : 2}, {x:4,y:3} ,{x:6, y:4},{x:7, y:3},{x:6, y:4}] }, //第五关 { //0是空的地图 //1是板砖 //3是目标点 state:[ [0,0,1,1,1,1,0,0], [0,0,1,3,3,1,0,0], [0,1,1,0,3,1,1,0], [0,1,0,0,0,3,1,0], [1,1,0,0,0,0,1,1], [1,0,0,1,0,0,0,1], [1,0,0,0,0,0,0,1], [1,1,1,1,1,1,1,1] ], person: {x : 4, y : 6}, box: [{x:4, y : 3}, {x:3,y:4} ,{x:4, y:5}, {x:5,y:5}] /* box : [ {x:3, y : 1}, {x:4, y : 1}, {x:4, y : 2}, {x:5, y : 5} ] */ }, //第六关 { //0是空的地图 //1是板砖 //3是目标点 state:[ [0,0,0,0,1,1,1,1,1,1,1,0], [0,0,0,0,1,0,0,1,0,0,1,0], [0,0,0,0,1,0,0,0,0,0,1,0], [1,1,1,1,1,0,0,1,0,0,1,0], [3,3,3,1,1,0,0,0,0,0,1,1], [3,0,0,1,0,0,0,0,1,0,0,1], [3,0,0,0,0,0,0,0,0,0,0,1], [3,0,0,1,0,0,0,0,1,0,0,1], [3,3,3,1,1,1,0,1,0,0,1,1], [1,1,1,1,1,0,0,0,0,0,1,0], [0,0,0,0,1,0,0,1,0,0,1,0], [0,0,0,0,1,1,1,1,1,1,1,0] ], person: {x : 5, y : 10}, box: [ {x:5, y:6}, {x:6, y:3}, {x:6, y:5}, {x:6, y:7}, {x:6, y:9}, {x:7, y:2}, {x:8, y:2}, {x:9, y:6} ] } ]有一个很重要的东西就是推箱子游戏的主要逻辑：因为小乌龟走的地方只能是空白的区域，而且乌龟前面有墙就不能走， 或者乌龟前面是箱子，就再判断箱子前面是否有墙， 如果没有墙乌龟和箱子都可以走往前走一步，如果有墙就不能走。每一次小乌龟走了都改变地图数据，然后重新生成界面，如此循环， 每一小乌龟走完都要检测地图数据中的箱子数据是否全对上了，对上了就给用户提示， 并进入下一关；
游戏的模板引擎用了handlebarsJS， 可以去官网看API 。 这个是写过的一篇博客，Handlebars的使用方法文档整理(Handlebars.js)：打开， 模板内容：
<script id="tpl" type="text/x-handlebars-template"> {{#initY}}{{/initY}} {{#each this}} {{#each this}} <div class="{{#getClass this}}{{/getClass}}" data-x="{{@index}}" data-y="{{#getY}}{{/getY}}" style="left:{{#calc @index}}{{/calc}};top:{{#calc 1111}}{{/calc}}"> <!--{{@index}} {{#getY}}{{/getY}} --> </div> {{/each}} {{#addY}}{{/addY}} {{/each}} </script>为Handlebars定了几个helper，包括initY， getClass， getY，calc 、、、、，模板引擎主要是辅助的作用， 这边用Handlebars不是很明智啊， 代码的可读性变差了点， 这里面也利用了闭包保存变量， 避免全局变量的污染：
(function() { var y = 0; Handlebars.registerHelper("initY", function() { y = 0; }); Handlebars.registerHelper("addY", function() { y++; }); Handlebars.registerHelper("getY", function() { return y; }); Handlebars.registerHelper("calc", function(arg) { //console.log(arg) if(arg!==1111) { return 50*arg + "px"; }else{ return 50*y + "px"; }; }); Handlebars.registerHelper("getClass", function(arg) { switch( arg ) { case 0 : return "bg" case 1 : return "block" case 2 : return "box" case 3 : return "target" }; }); window.util = { isMobile : function() { return navigator.userAgent.toLowerCase().indexOf("mobile") !== -1 || navigator.userAgent.toLowerCase().indexOf("android") !== -1 || navigator.userAgent.toLowerCase().indexOf("pad") !== -1; } } })();因为要兼容移动端， 我们要检查是否是手机或者平板，如果是的话，我就添加对应的DOM元素（方向键DOM元素），然后绑定对应的事件， zeptoJS提供了touch模块，我们要去官网去找，然后额外引用进来，打开地址 , 然后就可以使用swipeLeft，swipeUp，swipeDown， swipeRight 这几个事件：
if( window.util.isMobile() ) { $(window).on("swipeLeft",function() { _this.step("left"); }).on("swipeRight",function() { _this.step("right"); }).on("swipeUp",function() { _this.step("top"); }).on("swipeDown",function() { _this.step("bottom"); }); mobileDOM(); $(".arrow-up").tap(function() { _this.step("top"); }); $(".arrow-down").tap(function() { _this.step("bottom"); }); $(".arrow-left").tap(function() { _this.step("left"); }); $(".arrow-right").tap(function() { _this.step("right"); }); }else{ $(window).on("keydown", function(ev) { var state = ""; switch( ev.keyCode ) { case 37 : state = "left"; break; case 39 : state = "right"; break; case 38 : state = "top"; break; case 40 : state = "bottom"; break; }; _this.step(state) }); };因为要保存用户的当前关卡， 也额外引用了jQuery-cookies插件， 每一次闯关成功，我们就保存一次当前的闯关记录， 当用户不想玩或者别的原因关闭了浏览器， 过几天想重新玩的时候可以继续玩；
if( G.now+1 > G.level.length-1 ) { alert("闯关成功"); return ; }else{ //如果可用的等级大于当前的等级，就把level设置进去; if( G.now+1 > parseInt( $.cookie('level') || 0 )) { $.cookie('level' , G.now+1 , { expires: 7 }); }; start( G.now+1 ); return ; };所有的代码在这里：
