扫雷07 游戏逻辑设计
这才是这里最重要的，整个游戏这里的代码是最关键的。
查看这个游戏的相关函数调用在GameScene这个类中，相关的调用如下。 NoAroundmine函数
NoAroundmine函数的作用是在点击的区域满足以下三个条件的时候被调用
1、 没有被挖开
2、 不是去标记（插旗）
3、 其代笔的是周围没有雷（属性值为0）
当我们点击到属性值为0的区块的时候，说明这个位置周围没有雷。这个函数的作用就是将这个区块周围没有雷的区块都照出来。这是一个递归调用的函数

ContinueGame函数是判断是否继续游戏的函数，其作用是在游戏的过程中判断输赢。
如果踩到雷或者全部非雷区都找到的话就返回false，告诉calltouchended游戏不再继续。否则返回true，游戏继续。
当游戏不再继续的时候，这个函数负责根据输赢显示背景或者动画。
