/********************************************js俄罗斯方块源码***********************************************/ //作者：高山流水 QQ：21243468 //创建日期:2009-08-06 //版权声明:该作品由高山流水创作，转载请注明出处，谢谢合作！ //游戏设计说明： //1.由于该游戏属于二维游戏，所以布置好网格是写好该游戏的关键，无论是游戏窗口还是预览窗口、 //方块集虚拟map等都用到了网格的概念，这样做的好处可以避免频繁的获取元素的位置，另外还可以对方块集的移动 //进行精确的定位和变形。这里比较重要的一点就是提前定义好方块集的map，比如对于L方块集，应定义一个三乘三的正方形 //网格,然后根据L的每一个形状，确定方块集中的每个方块在正方形网格中的位置，另外还需要保存方块集在map //（游戏窗口或者预览窗）中的位置，这样任意时刻，通过方块集的位置，和方块在正方形网格中的位置，就可以确定 //方块集中的每一个方块在map中的位置。 //2.该游戏主要用到了一些OOP的思想。比如定义一个基类base，方块集类继承自base类,其中还有对象的封装，属性， //枚举的定义等,当然还有事件，委托，attribute，垃圾收集器等，因为时间关系，就不做代码演示了，各位有兴趣可以自己 //扩展一下，加深对js OOP的理解。 //3.js内置对象的扩展：比如Array.prototype.removeAt等 /********************************************js俄罗斯方块源码**********************************************/ var Sys = null;
