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); 30 if (links.Intersect(poses).Count() == 4) { // 刀把五 31 var tmp = poses.Except(links).ToList(); 32 if (IsCusp(tmp[0], p)) { 33 block.IsDead = true; 34 block.KeyPos = p; 35 } 36 } 37 }); 38 } else if (poses.Count == 4) { 39 poses.ForEach(p => { 40 var links = LinkPoses(p); 41 if (links.Intersect(poses).Count() == 4) { // 斗笠四 42 block.IsDead = true; 43 block.KeyPos = p; 44 } else if (links.Intersect(poses).Count() == 3 // 盘角曲四 45 && (p == new Pos(0, 0) || p == new Pos(0, 18) || p == new Pos(18, 0) || p == new Pos(18, 18))) { 46 block.IsDead = true; 47 } 48 }); 49 } else if (poses.Count == 3) { 50 poses.ForEach(p => { 51 var links = LinkPoses(p); 52 if (links.Intersect(poses).Count() == 3) { // 直三、曲三 53 block.IsDead = true; 54 block.KeyPos = p; 55 } 56 }); 57 } else if (poses.Count == 2) { 58 poses.ForEach(p => { 59 var links = LinkPoses(p); 60 if (links.Intersect(poses).Count() == 2) { 61 block.IsDead = true; 62 } 63 }); 64 } else if (poses.Count < 2) { 65 block.IsDead = true; 66 } 67 68 if (!isFirst && block.IsDead) { 69 m_BlackMeshes.RemoveAll(b => block.Poses.Contains(b)); 70 m_WhiteMeshes.AddRange(block.Poses); 71 } 72 }); 73 74 m_WhiteMeshBlocks.ForEach(block => { 75 var poses = block.Poses.ToList(); 76 block.Poses.ForEach(p => { 77 if (WhitePoses.Contains(p)) 78 poses.Remove(p); 79 LinkPoses(p).ForEach(l => { 80 if (m_BlackMeshes.Contains(l)) 81 poses.Remove(p); 82 }); 83 }); 84 if (poses.Count == 6) { 85 poses.ForEach(p => { 86 var links = LinkPoses(p); 87 if (links.Intersect(poses).Count() == 5) { // 梅花六 88 var tmp = poses.Except(links).ToList(); 89 if (IsCusp(tmp[0], p)) { 90 block.IsDead = true; 91 block.KeyPos = p; 92 } 93 } 94 }); 95 } else if (poses.Count == 5) { 96 poses.ForEach(p => { 97 var links = LinkPoses(p); 98 if (links.Intersect(poses).Count() == 4) { // 刀把五 99 var tmp = poses.Except(links).ToList();100 if (IsCusp(tmp[0], p)) {101 block.IsDead = true;102 block.KeyPos = p;103 }104 }105 });106 } else if (poses.Count == 4) {107 poses.ForEach(p => {108 var links = LinkPoses(p);109 if (links.Intersect(poses).Count() == 4) { // 斗笠四110 block.IsDead = true;111 block.KeyPos = p;112 } else if (links.Intersect(poses).Count() == 3 // 盘角曲四113 && (p == new Pos(0, 0) || p == new Pos(0, 18) || p == new Pos(18, 0) || p == new Pos(18, 18))) {114 block.IsDead = true;115 }116 });117 } else if (poses.Count == 3) {118 poses.ForEach(p => {119 var links = LinkPoses(p);120 if (links.Intersect(poses).Count() == 3) { // 直三、曲三121 block.IsDead = true;122 block.KeyPos = p;123 }124 });125 } else if (poses.Count == 2) {126 poses.ForEach(p => {127 var links = LinkPoses(p);128 if (links.Intersect(poses).Count() == 2) {129 block.IsDead = true;130 }131 });132 } else if (poses.Count < 2) {133 block.IsDead = true;134 }135 136 if (!isFirst && block.IsDead) {137 m_WhiteMeshes.RemoveAll(b => block.Poses.Contains(b));138 m_BlackMeshes.AddRange(block.Poses);139 }140 });141 142 if (isFirst) {143 m_BlackMeshBlocks.ForEach(block => {144 if (block.IsDead) {145 foreach (var pos in block.Poses) {146 var links = LinkPoses(pos);147 m_WhiteMeshBlocks.ForEach(w_block => {148 if (links.Intersect(w_block.Poses).Count() > 0) {149 if (w_block.IsDead) {150 BlackPosBlocks.ForEach(bp_block => {151 if (bp_block.Poses.Contains(pos)) {152 block.EmptyCount = bp_block.EmptyCount;153 }154 WhitePosBlocks.ForEach(wp_block => {155 if (wp_block.Poses.Intersect(w_block.Poses).Count() > 0) {156 w_block.EmptyCount = wp_block.EmptyCount;157 }158 });159 });160 if (block.EmptyCount > w_block.EmptyCount) {161 m_WhiteMeshes.RemoveAll(w => w_block.Poses.Contains(w));162 m_BlackMeshes.AddRange(w_block.Poses);163 } else if (block.EmptyCount < w_block.EmptyCount) {164 m_BlackMeshes.RemoveAll(b => block.Poses.Contains(b));165 m_WhiteMeshes.AddRange(block.Poses);166 }167 }168 }169 });170 }171 }172 });173 }174 175 UpdateMeshColors();176 }
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。
