Simone求VB高手帮我解释下这段俄罗斯方块代码的意思吧
的有关信息介绍如下：
Public Const BlockSize As Long = 4 //定义公共常量BlockSize＝4
Public Type BlockInfo
Box(0 To BlockSize - 1, 0 To BlockSize - 1) As Byte
End Type //定义BlockInfo类型数组Box(0 To BlockSize - 1, 0 To BlockSize - 1)
Public Const RotateStatusCount As Long = 4 //定义公共常量RotateStatusCount＝4
Public Const BlockCount As Long = 5 定义公共常量BlockCount＝5
Public Blocks(0 To RotateStatusCount - 1, 0 To BlockCount - 1) As BlockInfo ////定义数组Blocks(0 To RotateStatusCount - 1, 0 To BlockCount - 1)作为BlockInfo类型
补充说明：BlockSize指方块的大小。Box(0 To BlockSize - 1, 0 To BlockSize - 1)应该是显示下一个要落下的方块的预览区，所以是4*4的。RotateStatusCount是指落下的方块的朝向，有上下左右四种，所以等于4。BlockCount指方块的数量，等于5，应该指的是预览区中下一个方块的最大数量为5。Blocks(0 To RotateStatusCount - 1, 0 To BlockCount - 1)应该是指落下的方块的状态，包括朝向即个数。
还解析 我晕 自己找算法书去看
