五子棋三手交换是一种玩法规则,通常是在比赛过程中,当一方下完前三手后,双方可以协商交换先手和后手,然后再继续比赛。这种规则的目的是增加游戏的变数和趣味性,同时也能够提高比赛的公平性。
实现五子棋三手交换的关键在于记录双方的前三手棋步,并在需要交换时进行相应的处理。以下是一个简单的Java实现示例:
```
import java.util.Scanner;
public class Gobang {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
int[][] chessboard = new int[15][15]; // 棋盘
int player = 1; // 当前下棋者,默认为1
int x = -1, y = -1; // 当前下棋的坐标
int[] lastX = new int[3]; // 记录双方前三手的x坐标
int[] lastY = new int[3]; // 记录双方前三手的y坐标
int step = 0; // 当前步数
// 初始化棋盘
for (int i = 0; i < 15; i++) {
for (int j = 0; j < 15; j++) {
chessboard[i][j] = 0;
}
}
// 开始下棋
while (true) {
// 输出棋盘
System.out.println(" 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15");
for (int i = 0; i < 15; i++) {
System.out.print((i + 1) + " ");
for (int j = 0; j < 15; j++) {
if (chessboard[i][j] == 0) {
System.out.print("+ ");
} else if (chessboard[i][j] == 1) {
System.out.print("O ");
} else {
System.out.print("X ");
}
}
System.out.println();
}
// 输入坐标
System.out.print("请 " + (player == 1 ? "O" : "X") + " 方输入坐标(例如:3,5):");
String[] pos = input.nextLine().split(",");
x = Integer.parseInt(pos[0]) - 1;
y = Integer.parseInt(pos[1]) - 1;
// 判断坐标是否合法
if (x < 0 || x >= 15 || y < 0 || y >= 15) {
System.out.println("坐标不合法,请重新输入!");
continue;
}
if (chessboard[x][y] != 0) {
System.out.println("该位置已经有棋子,请重新输入!");
continue;
}
// 记录前三手
if (step < 3) {
lastX[step] = x;
lastY[step] = y;
}
// 判断是否交换
if (step == 3 && player == 2 && x == lastX[0] && y == lastY[0] && lastX[1] == lastX[2] && lastY[1] == lastY[2]) {
// 双方协商交换
System.out.println("双方协商交换先手和后手!");
int temp = lastX[0];
lastX[0] = lastX[1];
lastX[1] = temp;
temp = lastY[0];
lastY[0] = lastY[1];
lastY[1] = temp;
player = 1;
}
// 下棋
chessboard[x][y] = player;
// 判断是否连成五子
if (isWin(chessboard, x, y)) {
System.out.println((player == 1 ? "O" : "X") + " 方获胜!");
break;
}
// 判断是否平局
if (step == 224) {
System.out.println("平局!");
break;
}
// 切换下棋者
player = player == 1 ? 2 : 1;
step++;
}
}
// 判断是否连成五子
public static boolean isWin(int[][] chessboard, int x, int y) {
int player = chessboard[x][y];
int count = 1;
// 判断横向
for (int i = x - 1; i >= 0; i--) {
if (chessboard[i][y] == player) {
count++;
} else {
break;
}
}
for (int i = x + 1; i < 15; i++) {
if (chessboard[i][y] == player) {
count++;
} else {
break;
}
}
if (count >= 5) {
return true;
}
// 判断纵向
count = 1;
for (int j = y - 1; j >= 0; j--) {
if (chessboard[x][j] == player) {
count++;
} else {
break;
}
}
for (int j = y + 1; j < 15; j++) {
if (chessboard[x][j] == player) {
count++;
} else {
break;
}
}
if (count >= 5) {
return true;
}
// 判断左上-右下方向
count = 1;
for (int i = x - 1, j = y - 1; i >= 0 && j >= 0; i--, j--) {
if (chessboard[i][j] == player) {
count++;
} else {
break;
}
}
for (int i = x + 1, j = y + 1; i < 15 && j < 15; i++, j++) {
if (chessboard[i][j] == player) {
count++;
} else {
break;
}
}
if (count >= 5) {
return true;
}
// 判断右上-左下方向
count = 1;
for (int i = x - 1, j = y + 1; i >= 0 && j < 15; i--, j++) {
if (chessboard[i][j] == player) {
count++;
} else {
break;
}
}
for (int i = x + 1, j = y - 1; i < 15 && j >= 0; i++, j--) {
if (chessboard[i][j] == player) {
count++;
} else {
break;
}
}
if (count >= 5) {
return true;
}
return false;
}
}
```
五手两打是另一种玩法规则,与五子棋三手交换类似,是在比赛过程中,当一方下完前五手后,双方可以协商交换先手和后手,然后再继续比赛。
