JavaScript写一个小乌龟推箱子游戏

　　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；

　　推箱子游戏的在线DEMO ： 打开

　　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：

1. 　　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）
2. 　　箱子数据，一维数组（箱子的初始位置）
3. 　　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],

　　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 ;
                        };
