很多编程爱好者都编写过俄罗斯方块的游戏程序。很久以前，我用Tc2.0也做过一个；最近有好些朋友看见我以前的俄罗斯方块的程序后， 问我是怎么做的。我一直想把这个程序的整个过程写一份详细的东西，与各位编程爱好者分享，一直没空。正好现在放假了，而且离回家还有几天。于是我就把这个程序重新写了一遍，-Many programming enthusiasts have been prepared Tetris game procedures. A long time ago, I also made a Tc2.0 recently have some friends to see my previous procedure for the Russian box, the question is how I do. I have always wanted this process to write the whole process a detailed things to share with you programming enthusiasts, has been busy. Is now a holiday, and a few days away from home. So I put this process to re-write again,
