x01.Weiqi.10: 死活问题

估计得不错，点目后，仅一个方法：UpdateMeshes5() 就完美解决了梅花六、刀把五、斗笠四、盘角曲四等死活问题。先来看看效果图：

其代码如下：

 void UpdateMeshes5(bool isFirst = true)
         {
             UpdateAllMeshBlocks();

             m_BlackMeshBlocks.ForEach(block => {
                 var poses = block.Poses.ToList();
                 block.Poses.ForEach(p => {
                     if (BlackPoses.Contains(p))
                         poses.Remove(p);
                     LinkPoses(p).ForEach(l => {
                         if (m_WhiteMeshes.Contains(l))
                             poses.Remove(p);
                     });
                 });

                 if (poses.Count == ) {
                     poses.ForEach(p => {
                         var links = LinkPoses(p);
                         if (links.Intersect(poses).Count() == ) {    // 梅花六
                             var tmp = poses.Except(links).ToList();
                             if (IsCusp(tmp[], p)) {
                                 block.IsDead = true;
                                 block.KeyPos = p;
                             }
                         }
                     });

UpdateMeshes5()

因为涉及到比气问题，所以要调用两次。这又是多遍扫描的应有之意，相信已经见怪不怪了。

加点智能：

        {
            var empties = RoundThreePoses(m_CurrentPos).Intersect(EmptyPoses).ToList();
            int count = empties.Count;

            int backCount = ;

            for (int j = ; j < ; j++) {
