黑白棋

        黑白棋，又叫反棋、奥赛罗棋、苹果棋或翻转棋。黑白棋在西方和日本很流行。游戏通过相互翻转对方的棋子，最后以棋盘上谁的棋子多来判断胜负。它的游戏规则简单，因此上手很容易，但是它的变化又非常复杂。有一种说法是：只需要几分钟学会它，却需要一生的时间去精通它。

       黑白棋的棋盘是一个有8*8方格的棋盘。下棋时将棋下在空格中间，而不是像围棋一样下在交叉点上。开始时在棋盘正中有两白两黑四个棋子交叉放置，黑棋总是先下子。把自己颜色的棋子放在棋盘的空格上，而当自己放下的棋子在横、竖、斜八个方向内有一个自己的棋子，则被夹在中间的全部翻转会成为自己的棋子。并且，只有在可以翻转棋子的地方才可以下子。

 好了，知道了游戏规则我们如何去实现它呢？首先我们要去构建场景，也就是棋盘。我用64个Cube去创建（虽然很麻烦，但是可以控制Cube的高亮来提示玩家可以下的位置），一个Plane，以及四周的边框。棋子由两个Cylinder组成，一面黑一面白并设成预置物体。场景构建完毕，规则也了解了，接下来该实现了。首先要有一个虚拟棋盘去控制，我用了一个int型二维数组来表示，1表示黑棋 2表示白棋。一个gameobject型二维数组去存棋盘的64个Cube（实现提示），另一个gameobject型二维数组存棋子（控制反转）。高亮的棋盘玩家可以点击，没点击一次返回位置下的位置，在虚拟棋盘中去判断哪些棋子应该反转，之后更换玩家并在虚拟棋盘中计算可以下的位置，之后把这些Cube设成高亮，点击开关开启。这样循环下去，如果第一次没有找到可以下的位置，那么更换玩家，如果第二次没有找到则游戏结束，计算棋子数量决定胜负。

下面是初始化：

void Start (){numberChessBoard1 [4, 4] = 1;numberChessBoard1 [5, 5] = 1;numberChessBoard1 [4, 5] = 2;numberChessBoard1 [5, 4] = 2;gameObjectChessPiece [4, 4] = c1;gameObjectChessPiece [5, 5] = c2;gameObjectChessPiece [4, 5] = c3;gameObjectChessPiece [5, 4] = c4;GameObject[] a = GameObject.FindGameObjectsWithTag ("Cube");for (int i = 0; i < 64; i++) {for (int j = 0; j < 64; j++) {Vector3 p = new Vector3 (-3.5f + (i / 8), -0.4f, 3.5f - (i % 8));if (Vector3.Distance (a [j].transform.position, p) < 0.5f) {gameObjectChessBoard [i / 8 + 1, i % 8 + 1] = a [j];}}}}

玩家的变更以及胜利的判定

//玩家变更及胜利判定void Win () {for (int k = 0; k < 3; k++) {alter++;//棋盘高亮HighGreen (ref highGreen, numberChessBoard1, ref alter, player);if (alter == 1) {player = player % 2 + 1;GameObject.Find ("Text").GetComponent<GUIText>().text = "No way out,Players exchange";} else if (alter == 2) {int player1 = 0;int player2 = 0;for (int i = 0; i < 9; i++) {for (int j = 0; j < 9; j++) {if (numberChessBoard1 [i, j] == 1) {player1++;}if (numberChessBoard1 [i, j] == 2) {player2++;}}}if (player1 > player2) {GameObject.Find ("Text").GetComponent<GUIText>().text = "Black:" + player1 + "  White:" + player2 + "    Winer is black";} else if (player1 < player2) {GameObject.Find ("Text").GetComponent<GUIText>().text = "Black:" + player1 + "  White:" + player2 + "    Winer is white";} else {GameObject.Find ("Text").GetComponent<GUIText>().text = "equalize the score";}} else {break;}}}

棋盘是否高亮 需要对每一个棋子进行遍历，并依次判定其上、下、左、右、左上、左下、右上、右下

//棋盘高亮void HighGreen (ref int[,] highGreen, int[,] numberChessBoard1, ref int alter, int player){for (int i = 1; i < 9; i++) {for (int j = 1; j < 9; j++) {if (numberChessBoard1 [i, j] == player) {//rightfor (int k = i - 1; k >= 1; k--) {if (numberChessBoard1 [k, j] == player) {break;} else if (numberChessBoard1 [k, j] == 0) {if (numberChessBoard1 [k + 1, j] == player % 2 + 1) {highGreen [k, j] = 1;alter = 0;}break;}}//leftfor (int k = i + 1; k <= 8; k++) {if (numberChessBoard1 [k, j] == player) {break;} else if (numberChessBoard1 [k, j] == 0) {if (numberChessBoard1 [k - 1, j] == player % 2 + 1) {highGreen [k, j] = 1;alter = 0;}break;}}//upfor (int k = j + 1; k <= 8; k++) {if (numberChessBoard1 [i, k] == player) {break;} else if (numberChessBoard1 [i, k] == 0) {if (numberChessBoard1 [i, k - 1] == player % 2 + 1) {highGreen [i, k] = 1;alter = 0;}break;}}//downfor (int k = j - 1; k >= 1; k--) {if (numberChessBoard1 [i, k] == player) {break;} else if (numberChessBoard1 [i, k] == 0) {if (numberChessBoard1 [i, k + 1] == player % 2 + 1) {highGreen [i, k] = 1;alter = 0;}break;}}//rightUpfor (int k = i + 1; k <= 8; k++) {if (j - k + i <= 0 || j - k + i >= 9) {break;}if (numberChessBoard1 [k, j - k + i] == player) {break;} else if (numberChessBoard1 [k, j - k + i] == 0) {if (numberChessBoard1 [k - 1, j - k + i + 1] == player % 2 + 1) {highGreen [k, j - k + i] = 1;alter = 0;}break;}}//rightDownfor (int k = i + 1; k <= 8; k++) {if (j - i + k <= 0 || j - i + k >= 9) {break;}if (numberChessBoard1 [k, j - i + k] == player) {break;} else if (numberChessBoard1 [k, j - i + k] == 0) {if (numberChessBoard1 [k - 1, j - i + k - 1] == player % 2 + 1) {highGreen [k, j - i + k] = 1;alter = 0;}break;}}//leftUpfor (int k = i - 1; k > 0; k--) {if (j - i + k <= 0 || j - i + k >= 9) {break;}if (numberChessBoard1 [k, j - i + k] == player) {break;} else if (numberChessBoard1 [k, j - i + k] == 0) {if (numberChessBoard1 [k + 1, j - i + k + 1] == player % 2 + 1) {highGreen [k, j - i + k] = 1;alter = 0;}break;}}//leftUpfor (int k = i - 1; k > 0; k--) {if (j - k + i <= 0 || j - k + i >= 9) {break;}if (numberChessBoard1 [k, j - k + i] == player) {break;} else if (numberChessBoard1 [k, j - k + i] == 0) {if (numberChessBoard1 [k + 1, j - k + i - 1] == player % 2 + 1) {highGreen [k, j - k + i] = 1;alter = 0;}break;}}}}}StartCoroutine ("ChessBoard");}//高亮延迟IEnumerator ChessBoard (){yield return new WaitForSeconds (0.6f);for (int i = 0; i < 9; i++) {for (int j = 0; j < 9; j++) {if (highGreen [i, j] == 1) {gameObjectChessBoard [i, j].GetComponent<Renderer> ().material = green;gameObjectChessBoard [i, j].GetComponent<Play> ().play = true;if (player != 2 || !ai) {highGreen [i, j] = 0;}}}}}

智能AI（其实谈不上智能啦，没写什么算法 知识单纯的随机而已 算法等有时间再写吧~）

//智能AIIEnumerator AiPlay () {yield return new WaitForSeconds (0.5f);for (int i = 0; i < 9; i++) {for (int j = 0; j < 9; j++) {if (highGreen[i,j] == 1) {way.Add(i * 10 + j);}}}if (ai == true && player == 2) {int r = Random.Range(0,way.Count);gameObjectChessBoard [way[r] / 10,way[r] % 10].GetComponent<Play> ().aiPlay = true;m =  way[r] / 10;n = way[r] % 10;way.Clear();}for (int i = 0; i < 9; i++) {for (int j = 0; j < 9; j++) {highGreen [i, j] = 0;}}}

更新虚拟棋盘 同样对返回的位置的上、下、左、右、左上、左下、右上、右下进行判断

//更新虚拟棋盘void Renovate () {for (int k = m - 1; k >= 1; k--) {if (numberChessBoard1 [k, n] == 0) {break;} else if (numberChessBoard1 [k, n] == player % 2 + 1) {if (numberChessBoard1 [k + 1, n] == player) {for (int i = k + 1; i < m; i++) {numberChessBoard1 [i, n] = player % 2 + 1;}}break;}}for (int k = m + 1; k <= 8; k++) {if (numberChessBoard1 [k, n] == 0) {break;} else if (numberChessBoard1 [k, n] == player % 2 + 1) {if (numberChessBoard1 [k - 1, n] == player) {for (int i = k - 1; i > m; i--) {numberChessBoard1 [i, n] = player % 2 + 1;}}break;}}for (int k = n + 1; k <= 8; k++) {if (numberChessBoard1 [m, k] == 0) {break;} else if (numberChessBoard1 [m, k] == player % 2 + 1) {if (numberChessBoard1 [m, k - 1] == player) {for (int i = k - 1; i > n; i--) {numberChessBoard1 [m, i] = player % 2 + 1;}}break;}}for (int k = n - 1; k >= 1; k--) {if (numberChessBoard1 [m, k] == 0) {break;} else if (numberChessBoard1 [m, k] == player % 2 + 1) {if (numberChessBoard1 [m, k + 1] == player) {for (int i = k + 1; i < n; i++) {numberChessBoard1 [m, i] = player % 2 + 1;}}break;}}for (int k = m + 1; k <= 8; k++) {if (n - k + m <= 0 || n - k + m >= 9) {break;}if (numberChessBoard1 [k, n - k + m] == 0) {break;} else if (numberChessBoard1 [k, n - k + m] == player % 2 + 1) {if (numberChessBoard1 [k - 1, n - k + m + 1] == player) {for (int i = k - 1; i > m; i--) {numberChessBoard1 [i, n - i + m] = player % 2 + 1;}}break;}}for (int k = m + 1; k <= 8; k++) {if (n - m + k <= 0 || n - m + k >= 9) {break;}if (numberChessBoard1 [k, n - m + k] == 0) {break;} else if (numberChessBoard1 [k, n - m + k] == player % 2 + 1) {if (numberChessBoard1 [k - 1, n - m + k - 1] == player) {for (int i = k - 1; i > m; i--) {numberChessBoard1 [i, n - m + i] = player % 2 + 1;}}break;}}for (int k = m - 1; k > 0; k--) {if (n - m + k <= 0 || n - m + k >= 9) {break;}if (numberChessBoard1 [k, n - m + k] == 0) {break;} else if (numberChessBoard1 [k, n - m + k] == player % 2 + 1) {if (numberChessBoard1 [k + 1, n - m + k + 1] == player) {for (int i = k + 1; i < m; i++) {numberChessBoard1 [i, n - m + i] = player % 2 + 1;}}break;}}for (int k = m - 1; k > 0; k--) {if (n - k + m <= 0 || n - k + m >= 9) {break;}if (numberChessBoard1 [k, n - k + m] == 0) {break;} else if (numberChessBoard1 [k, n - k + m] == player % 2 + 1) {if (numberChessBoard1 [k + 1, n - k + m - 1] == player) {for (int i = k + 1; i < m; i++) {numberChessBoard1 [i, n - i + m] = player % 2 + 1;}}break;}}}

棋子的反转

//棋子翻转void Flip () {for (int i = 0; i < 9; i++) {for (int j = 0; j < 9; j++) {if (gameObjectChessPiece [j, i] != null && ((numberChessBoard1 [i, j] - 1) * 180 - gameObjectChessPiece [j, i].transform.eulerAngles.z > -10 && (numberChessBoard1 [i, j] - 1) * 180 - gameObjectChessPiece [j, i].transform.eulerAngles.z < 10)) {gameObjectChessPiece [j, i].GetComponent<Flip> ().flip = true;}}}}

以上方法在UpDate中调用即可 除此之外 棋盘的每个Cube上都有相同的脚本

void Update () {player = GameObject.Find ("Script").GetComponent<BlackAndWhiteChess> ().player;gameObjectChessBoard = GameObject.Find ("Script").GetComponent<BlackAndWhiteChess> ().gameObjectChessBoard;if (aiPlay) {Playing ();aiPlay = false;}}void OnMouseDown() {if (play && !aiPlay) {Playing();}}void Playing () {GameObject a = Instantiate(p,coordinate,Quaternion.Euler(180 * player,0,0)) as GameObject;GameObject.Find ("Script").GetComponent<BlackAndWhiteChess> ().gameObjectChessPiece[n,m] = a;for (int i = 1; i < 9; i++) {for (int j = 1; j < 9; j++) {gameObjectChessBoard[i,j].GetComponent<Renderer>().material = blackGreen;gameObjectChessBoard[i,j].GetComponent<Play>().play = false;}}GameObject.Find ("Text").GetComponent<GUIText>().text = "";GameObject.Find ("Script").GetComponent<BlackAndWhiteChess> ().m = m;GameObject.Find ("Script").GetComponent<BlackAndWhiteChess> ().n = n;GameObject.Find ("Script").GetComponent<BlackAndWhiteChess> ().numberChessBoard1[m,n] = player;GameObject.Find ("Script").GetComponent<BlackAndWhiteChess> ().player = player % 2 + 1;GameObject.Find ("Script").GetComponent<BlackAndWhiteChess> ().play= true;}}

棋子上会有反转简本 用一个bool变量控制。

注：棋子的数组好像定义反了0.0 懒得去改了就这样吧~
