旋转俄罗斯方块的原理及VB源码，作者：尹强，module.bas文件中BitBlt 函数的作用是：位操作位图，实现不规则的方块的动作。除此之外，里面还有不少编写俄罗斯方块游戏的方法和模块，比如判断方块是否堆满，如果一行已经堆满，则将此行上面的图象全部向下移动一点，如果目前方块的顶点位置 <=0 ，则表示全部堆满；还可判断方块能否翻转，能否向左、向右、向上、向下移动；随机从 7 个方块中选择一个组建成下一个方块图形等-Tetris rotation principle and VB source, author: Yin strong role module.bas file BitBlt function is: Bit operation bitmap realize irregular block action. In addition, there is also a lot of Tetris game written methods and modules, such as the box is filled with judgment, if a line has been filled, the entire image above this line moves down a bit, if the current box vertex position <= 0, then all piled　may also determine whether the flip box, whether left, right, up, move down　randomly select a graphic form into the next block from the 7 box, etc.
