C++五子棋(六&七)——游戏结束

规则原理

如图

判断游戏结束

• chessData.h

//row,col    表示当前落子
bool checkWin(ChessData* game, int row, int col);

• 横、竖、斜（斜有两种）共四种情况，每种情况根据当前落子往后遍历5个子，有一种符合就胜利
• chessData.cpp

bool checkWin(ChessData* game, int row, int col){
  //横
  for(int i = 0; i < 5; i++){
    if(col - i >= 0 &&
      col - i + 4 < BOARD_GRAD_SIZE &&
      game->chessMap[row][col-i] == game->chessMap[row][col-i+1] &&
      game->chessMap[row][col-i] == game->chessMap[row][col-i+2] &&
      game->chessMap[row][col-i] == game->chessMap[row][col-i+3] &&
      game->chessMap[row][col-i] == game->chessMap[row][col-i+4]){return true;}
  }

  //竖
  for(int i = 0; i < 5; i++){
    if(row - i >= 0 &&
      row - i + 4 < BOARD_GRAD_SIZE &&
      game->chessMap[row-i][col] == game->chessMap[row-i+1][col] &&
      game->chessMap[row-i][col] == game->chessMap[row-i+2][col] &&
      game->chessMap[row-i][col] == game->chessMap[row-i+3][col] &&
      game->chessMap[row-i][col] == game->chessMap[row-i+4][col]){return true;}
  }

  // “/”方向
  for(int i = 0; i < 5; i++){
    if(row + i < BOARD_GRAD_SIZE &&
       row + i - 4 >= 0 &&
       col - i >= 0 &&
       col - i + 4 < BOARD_GRAD_SIZE &&
      game->chessMap[row+i][col-i] == game->chessMap[row+i-1][col-i+1] &&
      game->chessMap[row+i][col-i] == game->chessMap[row+i-2][col-i+2] &&
      game->chessMap[row+i][col-i] == game->chessMap[row+i-3][col-i+3] &&
      game->chessMap[row+i][col-i] == game->chessMap[row+i-4][col-i+4]){return true;}
  }

  // “\”方向
  for(int i = 0; i < 5; i++){
    if(row - i >= 0 &&
       row - i - 4 < BOARD_GRAD_SIZE &&
       col - i >= 0 &&
       col - i + 4 < BOARD_GRAD_SIZE &&
      game->chessMap[row-i][col-i] == game->chessMap[row-i+1][col-i+1] &&
      game->chessMap[row-i][col-i] == game->chessMap[row-i+2][col-i+2] &&
      game->chessMap[row-i][col-i] == game->chessMap[row-i+3][col-i+3] &&
      game->chessMap[row-i][col-i] == game->chessMap[row-i+4][col-i+4]){return true;}
  }

  return false;

}

调用接口

• main.cpp

#include <stdio.h>

bool checkOver(){
  if(checkWin(&game, clickPosRow, clickPosCol)){
    Sleep(1500);
    if(game.playFlag = false){
      //黑棋胜利，此时标记已经转为白棋落子
      mciSendString("play res/不错.mp3", 0, 0, 0);
      loadimage(0, "res/胜利.jpg");
      score += 100; //更新分数
    }else{
      mciSendString("play res/失败.mp3", 0, 0, 0);
      loadimage(0, "res/失败.jpg");
      score -= 100; //同理
    }

    //用于显示分数
    char scoreText[64];
    sprintf(scoreText, "当前分数：%d", score);
    outtextxy(310, 800, scoreText);

    //记录分数
    FILE* fp = fopen("score.data", "wb");
    fwrite(&score, sizeof(score), 1, fp);
    fclose(fp);

    getch();
    return true;

  }

  return false;

}

显示分数

• main.cpp

#define INIT_SCORE 1000
int score; //全局变量

void initScore(){
  //分数字体设置
  settextcolor(WHITE); //color
  settextstyle(50, 0, "微软雅黑");  //style

  FILE *fp = fopen("score.data", "rb");
  if(fp == NULL){
    score = INIT_SCORE;
  }else{
    fread(&score, sizeof(score), 1, fp);
  }
  if (fp)fclose(fp);

}

• 然后在main.cpp文件的 init() 函数定义中 继续 添加代码

initScore(); //这一行添加到init()函数定义中

main函数

• main.cpp 代码如下

int main(void){
  init();

  while(1){
    //一直检测鼠标点击
    MOUSEMSG msg == GetMouseMsg();
    if(msg.uMsg == WM_LBUTTONDOWN){
      manGo();
      if(checkOver()){
        init();
        continue;
      }

      AI_GO();
      if(checkOver()){
        init();
        continue;
      }

    }

  }

  closegraph();
  return 0;

}
