JavaScript实现俄罗斯方块的核心逻辑与模块化架构

var cfg = {
  width:14,
  height:20,
  time : 400
};
requirejs.config({
  baseUrl: 'libs',
  paths: {
    app: '../app'
  }
});

requirejs(["app/controller/mainController","app/view/mobileDOM","app/util"], function(con, mobileDOM, util) {

  if(util.isMobile()) {
    mobileDOM.addDOM();
  };
  con();
});

define(["app/util"],function(util) {
  //分数模块,游戏开始的时候会用到;
  var score = {};
  require(["app/model/score"],function(defineScore) {
    score = defineScore;
  });

  var startGame = function() {
    //把当前的input元素禁用;
    $(this).attr("disabled","true");
    requirejs(["app/model/data","app/view/init","app/model/Block"], function(data, view, Block){
      //初始化方块;
      var block = new Block;
      var mapData = {};

      //方块发生改变的时候，我们用回调重新渲染界面;
      block.onupdate( function() {
        var blockData = this.get();
        //把数据格式转化成map数据;
        mapData = data.extend(blockData);
        $("#table").html( view( mapData ) );
      });

      block.testTouch = data.testTouch;

      //如果元素触底了或者是元素已经被卡主不能动的情况下;
      block.onend(function() {
        //这个说明当前的block触底了
        data.set( mapData );
        //我们需要重新生成一个方块, 直接调用newBlock即可;
        block.newBlock();
        //通过data计算，如果有连接起来的一条线，就执行SCORE回调, 随之会更新当前界面的分值;
        //如果方块跑到了最上面就是游戏失败了;
        data.oncalculate( score.addScore , block.destory.bind(block));
      });

      //现在才开始绑定事件
      if(!util.isMobile()) {
        $(window).keydown(function(ev) {
          if(ev.keyCode === 37) {
            block.add(block.moveLeft,"left");
          }else if( ev.keyCode === 39 ) {
            block.add(block.moveRight,"right");
          }else if( ev.keyCode === 40 ) {
            block.add(block.moveDown,"down");
          }else if( ev.keyCode === 38 ) {
            block.rotate();
          };
        });
      }else{
        $(".arrow-up").tap(function() {
          block.rotate();
        });
        $(".arrow-down").tap(function() {
          block.add(block.moveDown,"down");
        });
        $(".arrow-left").tap(function() {
          block.add(block.moveLeft,"left");
        });
        $(".arrow-right").tap(function() {
          block.add(block.moveRight,"right");
        });
      };
    });
  };

  //绑定界面事件 ,keyDown;
  var bindEvent = function() {
    //start....
    $("#start").click(startGame)
  };
  //为移动端添加DOM节点,
  //然后绑定移动端的事件;

  return function() {
    bindEvent();
