二、游戏介绍

《五子棋》 是一种两人对弈的纯策略型棋类游戏，棋具与围棋通用，是起源于中国古代的传统黑白棋种之一。发展于日本，流行于欧美。容易上手，老少皆宜，而且趣味横生，引人入胜；不仅能增强思维能力，提高智力，而且富含哲理，有助于修身养性。

比赛规则：

  • 行棋顺序：黑先、白后，相互顺序落子。
  • 判断胜负：最先在棋盘横向、竖向、斜向形成连续的相同色五个棋子的一方为胜。黑棋禁手判负，白棋无禁手。黑棋禁手包括三三禁手，四四禁手，长连禁手。如分不出胜负，则定为平局。

棋型解释：

  • 五连：五颗同色棋子连在一起，即4个方向的11111这种形式的棋型。
  • 活四：有2个成五点的四颗棋子，即4个方向的011110这种形式的棋型，注意两边一定要有空格。
  • 冲四：有1个成五点的四颗棋子，棋型有点多。
  • 活三：可以形成活四的三颗棋子

禁手规则：

  • 三三禁手：由于黑方落一子，同时形成二个或二个以上黑方活三的局面
  • 四四禁手：由于黑方落一子，同时形成二个或二个以上黑方四（活四或者冲四）的局面
  • 长连禁手：由于黑方落一子，形成六个或者六个以上的同色连续棋子

1、登录页面

运行程序后需注册账号使用，也可使用我注册过的账号（账号：liangdianjun，密码：123456），可在项目文档user.xls查看。

话不多说，直接上代码

2、算法程序

该程序实现了对五子棋分数的计算，计算竖横斜黑子和白子数量，谁先达成五分（即五子）则胜利。

返回棋盘上某个空点的分数

	int sum = 0;

   0, 0, 0, 0};
	int downcount[] = new int[] {
   0, 0, 0, 0};
	int upflag[] = new int[] {
   0, 0, 0, 0};
	int downflag[] = new int[] {
   0, 0, 0, 0};
	for(int color = 1; color <= 2; color++) {
   //计算双方的分数
		
		map[X][Y] = color;//先将该点放白子
		/*******************************************计算横向棋子***********************/

估值算法,返回一个数组，用于记录坐标

public static int[] evalute(int map[][], int depth, int computerColor) {
   
	int maxscore = 0;
	Random r = new Random();
	int pos[][] = new int[10][2];{
   
		for(int i = 0; i < pos.length; i++) {
   
			for(int j = 0; j < pos[i].length; j++) {
   
				pos[i][j] = 0;
			}
		}
	}
	int FLAG = 0;
	int score[][] = new int[15][15];{
   //初始化计分数组
		for(int i = 0; i < 15; i++) {
   
			for(int j = 0; j < 15; j++) {
   
				score[i][j] = 0;
			}
		}
	}
	int position[] = new int[]{
   0, 0};//初始化位置坐标数组
	for(int i = 6 - depth; i <= 8 + depth && i <= 14; i++) {
   //搜索横坐标
		for(int j = 6 - depth; j <= 8 + depth && j <= 14; j++) {
   //搜索纵坐标
			if(map[i][j] == 0) {
   //表示该点在棋盘上面为空
				score[i][j] = countScore(map, i, j, computerColor);
				if(maxscore < score[i][j]) {
   
					maxscore = score[i][j];//记录当前棋盘分数的最大值
				}
			}
		}
	}
	for(int i = 6 - depth; i <= 8 + depth && i <= 14; i++) {
   
		for(int j = 6 - depth; j <= 8 + depth && j <= 14; j++) {
   
			if(score[i][j] == maxscore) {
   
				pos[FLAG][0] = i;
				pos[FLAG++][1] = j;
			}
		}
	}
	int m = r.nextInt(FLAG);
	position[0] = pos[m][0];
	position[1] = pos[m][1];
	return position;
}

//极大极小值算法
public int minimax(int map[][], int chessColor) {
   
	return chessColor;
	
}

//alpha beta剪枝
public void alphaBetaCutting(int map[][], int chessColor){
   
	
}

3、棋盘实现

该算法按照五子棋规则，实现了最基本的打子，棋盘布局等功能。电脑可以计算玩家的棋子位置，严防死守（我完全没有机会赢😃，胜利的小伙伴可评论炫一波🧐），最终连成五子则结束。（此代码较多，展示部分代码，可下载完整版查看学习）

电脑下棋函数

private void tuntoComputer() {
   //电脑下棋
	if(depth >= 7) {
   
		depth = 6;
	}
	position = Algorithm.evalute(map, depth, computerColor);//调用估值函数
	map[position[0]][position[1]] = computerColor;
	imapflag[flag] = position[0];//将坐标存放在悔棋标记数组中
	jmapflag[flag] = position[1];
	newchessX = position[0];//新棋子标记记录坐标
	newchessY = position[1];
	int a = Math.max(Math.abs(position[0] - 7), Math.abs(position[1] - 7));//计算该点到中心的最大的距离
	depth = Math.max(depth, a);//不断更新depth的值
	flag ++;
	chessboardEmpty = 1;//棋盘标记为有棋子
	player = 1;//玩家下棋标志置0
	computer = 0;//电脑下棋标志为1
	judgeFlag = 1;
	repaint();
}

判断棋子是否连成五个

public void judge() {
   
	for(t = newchessX,s = newchessY,count = 0; t >=0 && s >= 0 && count <= 4; t--,s--,count++) {
   
		comeX = t;
		comeY = s;
	}
	for(t = newchessX, s = newchessY, count = 0; t <=14 && s >= 0 && count <= 4; t++, s--, count++) {
   
		toX = t;
		toY = s;
	}
	if(winFLAG == 0) {
   
		for(int ch = 1; ch <=2; ch++) {
   
			CHESSCOLOR = ch;
			//判断横向棋子
			for(s = (newchessX - 4) >=0 ? (newchessX - 4) : 0 ; s <= newchessX; s++) {
   //表示玩家获胜
			    t = newchessY;
				if(map[s][t] == CHESSCOLOR && s < 11) {
   //行棋子数量计算
					if(map[s + 1][t] == CHESSCOLOR) {
   
						if(map[s + 2][t] == CHESSCOLOR) {
   
							if(map[s + 3][t] == CHESSCOLOR) {
   
								if(map[s + 4][t] == CHESSCOLOR) {
   
									winX = s;
									winY = t;
									winWay = 1;
									if(CHESSCOLOR == 1) {
   //白棋
										winFLAG = 1;

   //黑棋
										winFLAG = 2;
									}
									break;
								}
							}
						}
					}
				}
			}
			if(winFLAG != 0) {
   //如果某一方赢了就直接退出
				break;
			}
		//判断列项棋子
			for(t = (newchessY - 4) >=0 ? (newchessY - 4) : 0 ; t <= newchessY; t ++) {
   
				s = newchessX;
				if(map[s][t] == CHESSCOLOR && t < 11) {
   //列棋子数量计算
					if(map[s][t + 1] == CHESSCOLOR) {
   
						if(map[s][t + 2] == CHESSCOLOR) {
   
							if(map[s][t + 3] == CHESSCOLOR) {

									winX = s;

   //白棋

									}else {
   //黑棋
										winFLAG = 2;
									}
									break;
								}
							}
						}
					}
				}
			}
			if(winFLAG != 0) {
   //如果某一方赢了就直接退出
				break;
			}
		//判断左上到右下棋子
			for(s = comeX, t = comeY; s <= newchessX && t <= newchessY; s ++, t++) {
   
				if(map[s][t] == CHESSCOLOR && s < 11 && t < 11) {
   //斜下棋子数量计算
					if(map[s + 1][t + 1] == CHESSCOLOR) {
   
						if(map[s + 2][t + 2] == CHESSCOLOR) {
   
							if(map[s + 3][t + 3] == CHESSCOLOR) {
   
								if(map[s + 4][t + 4] == CHESSCOLOR) {
   
									winX = s;
									winY = t;
									winWay = 3;
									if(CHESSCOLOR == 1) {
   //白棋
										winFLAG = 1;
									}else {
   //黑棋
										winFLAG = 2;
									}
									break;
								}
							}
						}
					}
				}
			}
			if(winFLAG != 0) {
   //如果某一方赢了就直接退出
				break;
			}
		//判断右上到左下棋子
			for(s = toX, t = toY; s >= newchessX && t <= newchessY; s --, t++) {
   
				if(map[s][t] == CHESSCOLOR && s >= 4 && t < 11) {
   //斜上棋子数量计算
					if(map[s - 1][t + 1] == CHESSCOLOR) {
   
						if(map[s - 2][t + 2] == CHESSCOLOR) {
   
							if(map[s - 3][t + 3] == CHESSCOLOR) {
   
								if(map[s - 4][t + 4] == CHESSCOLOR) {
   
									winX = s;
									winY = t;
									winWay = 4;
									if(CHESSCOLOR == 1) {
   //白棋
										winFLAG = 1;
									}else {
   //黑棋
										winFLAG = 2;
									}
									break;
								}
							}
						}
					}
				}
			}
			if(winFLAG != 0) {
   //如果某一方赢了就直接退出
				break;
			}
		}
	}
}

五、文末总结

通过学习《五子棋》游戏的实现，让我对swing的相关知识有了进一步的了解，对java这门语言也有了比以前更深刻的认识。java的一些基本语法，比如数据类型、运算符、程序流程控制和数组等，理解更加透彻。java最核心的核心就是面向对象思想，对于这一个概念，又多了更深层次的领悟。
