零打碎敲学Android(三)—俄罗斯，你为什么是方块的?

俄罗斯方块原本是前苏联(俄罗斯)科学家阿列克谢·帕基特诺夫（Алексей Леонидович Пажитнов）在1984年6月利用空闲时间所编写的游戏程序 ，据说游戏的作者最喜欢网球（Tennis）运动，于是，他把来源于希腊语的tetra（意为“四”）与其结合，造了“tetris”一词，之后开始提供授权给各个游戏公司。在那个时代，游戏机甚至于计算机的运算能力普遍较低（当时盛行传说中的640KB内存……），游戏堪称匮乏之极，因此简单易写的俄罗斯方块迅速普及， 造成各平台上软件大量发行的“恐怖”现象。

 

传说中Game Boy版的俄罗斯方块层在日本大卖424万套，是Game Boy史上卖得最好的游戏。海湾战争时，也是前线美军最常拿来消磨时间的游戏之一（如果鄙人没记错的话，GB是美军当时的标准装备之一|||，传说美军是一边玩着口袋妖怪，一边战胜了伊拉克～～～）。

 

俄罗斯方块的游戏规则：

          * 俄罗斯方块是由下面这几种常见方块构成，全部为四点组成：
          o 长条：一次最多消除四层
          o 7（左右）：最多消除三层，或消除二层
          o 田：消除一至二层
          o S（左右）：最多二层，容易造成孔洞
          o T：最多二层
          o 部分游戏有单格方块，可以穿透固定的方块到达最下层空位。其他的改版中出现更多特别的造型。

 

 

游戏方式：

    * 方块会从区域上方开始缓慢继续落下。
    * 玩家可以做的操作有：以90度为单位旋转方块，以格子为单位左右移动方块，让方块加速落下。
    * 方块移到区域最下方或是着地到其他方块上无法移动时，就会固定在该处，而新的方块出现在区域上方开始落下。
    * 当区域中某一列横向格子全部由方块填满，则该列会消失并成为玩家的得分。同时删除的列数越多，得分指数上升。
    * 当固定的方块堆到区域最上方而无法消除层数时，则游戏结束。

一般来说，游戏还会提示下一个要落下的方块，熟练的玩家会计算到下一个方块，评估现在要如何进行。由于游戏能不断进行下去，对商业用游戏不太理想，所以一般还会随着游戏的进行而加速提高难度，通常打到最后时，多眨一次眼就可能牺牲掉……

 

PS:另外补充一点，俄罗斯方块事实上是有知识产权的。最初的俄罗斯方块知识产权由前苏联外国贸易协会（ELORG）持有，在苏联over之后，由The Tetris Company继承，但由于“非法”使用者数量过大，事实上陷入了无法收取任何使用费的窘态中。自1990年代初期开始，全世界大量流行的小型游戏机，多半都有类似于俄罗斯方块的游戏，不过——9成9都不是授权产品。

 

闲话少说，既然是如此简单的东东，今天我们也用Java写两个俄罗斯方块好了。

与往常一样，一个例子写两台平台的，首先是PC版的实现，源码如下：

与前面的实例一样，都是先在PC上通过LGame-Simple调好，而后做函数替换移植到Android，写PC版用了一个小时，移植过去5分钟不到，吼吼吼……
