The push box game is an old game. There are various versions on the Internet. Let me talk about the simple implementation of the push box game, as well as some reference videos and examples I found;

The following is the rendering:

This box dragging game has been adapted to the mobile terminal. I used zepto’s touch module to control the turtle to go in different directions by sliding the screen with your finger;

Because the Sokoban game is relatively simple, the code is written directly in a procedural way. The module is two Views and Model, and the rest is the user's event Controller. Every time the user presses the direction key on the keyboard, the data will be changed. Model data, then regenerate the static HTML of the game, and then insert it into the interface using innerHTML to automatically generate DOM nodes;

The level model of the game is data. I divided the data of each level into three pieces:

Map data, two-dimensional array (map data includes tiles, target location of the box, and blank location)
Box data, one-dimensional array (initial position of the box)
Data of little turtle, json object
Each level has corresponding game level data. The simulated data is as follows: 

      level: [
        {
          //0是空的地图
          //1是板砖
          //3是目标点

            [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}]

One very important thing is the main logic of the push box game: because the place where the little turtle can only walk is a blank area, and if there is a wall in front of the turtle, it cannot walk, or if there is a box in front of the turtle, then judge the front of the box. Is there a wall? If there is no wall, both the turtle and the box can move forward. If there is a wall, they cannot move. Every time the little turtle walks away, the map data is changed, and then the interface is regenerated. In this cycle, after every little turtle walks, it will check whether the box data in the map data are all aligned. If they are aligned, the user will be prompted and entered. Next level;

The game’s template engine uses handlebarsJS. You can go to the official website to see the API. This is a blog I wrote, Handlebars usage documentation (Handlebars.js): Open, template content: 

  <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>

Several helpers are defined for Handlebars, including initY, getClass, getY, calc,,,,. The template engine is mainly used as an auxiliary function. It is not very wise to use Handlebars here. The readability of the code becomes a bit worse. , closures are also used to save variables to avoid pollution of global variables: 

    (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;
        }
      }
    })();

Because it needs to be compatible with mobile devices, we need to check whether it is a mobile phone or tablet. If so, I will add the corresponding DOM element (direction key DOM element), and then bind the corresponding event. zeptoJS provides the touch module, we Go to the official website to find it, then add additional references, open the address, and then you can use the swipeLeft, swipeUp, swipeDown, swipeRight events: 

        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)
          });
        };

Because we need to save the user’s current level, we also use the jQuery-cookies plug-in. Every time a level is successfully cleared, we will save the current level record. When the user does not want to play or closes the browser for other reasons, the browser will be closed after a few days. You can continue playing when you want to play again; 

            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 ;
            };
