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：

 1 void UpdateMeshes5(bool isFirst = true) 2     { 3       UpdateAllMeshBlocks(); 4  5       m_BlackMeshBlocks.ForEach(block => { 6         var poses = block.Poses.ToList(); 7         block.Poses.ForEach(p => { 8           if (BlackPoses.Contains(p)) 9             poses.Remove(p); 10           LinkPoses(p).ForEach(l => { 11             if (m_WhiteMeshes.Contains(l)) 12               poses.Remove(p); 13           }); 14         }); 15  16         if (poses.Count == 6) { 17           poses.ForEach(p => { 18             var links = LinkPoses(p); 19             if (links.Intersect(poses).Count() == 5) {  // 梅花六 20               var tmp = poses.Except(links).ToList(); 21               if (IsCusp(tmp[0], p)) { 22                 block.IsDead = true; 23                 block.KeyPos = p; 24               } 25             } 26           }); 27         } else if (poses.Count == 5) { 28           poses.ForEach(p => { 29             var links = LinkPoses(p);
