俄罗斯方块删除行问题

Question

我正在尝试在XNA中创建一个俄罗斯方块游戏，以便更好地学习在未来制作更好的游戏。我遇到的唯一问题是游戏的“删除行”功能。我有一个整数矩阵来保存块中的所有行数。每当我创建一个新的块时，我在指定的行中增加一个计数。然后，我检查矩阵中的任何值是否达到或超过10.然后，如果有，则删除该行中的所有块。我遇到的问题是它不可靠，并且它不会跟踪计数以及它应该出于某种原因，有时它不会删除该行中的所有块。如果您需要查看其他课程，请告诉我。谢谢，帮助表示赞赏。

[编辑] 向下移动的作品就好了零件，它只是删除麻烦的行。我也试着尽我所能发表评论，如果您有任何问题，请提问。再次感谢。

当我遍历正在检查的块时，如果删除它，我没有递减迭代变量来检查下一个块 - 因此所有块都未被检查。
