qt 中国象棋源码，界面学习

# Chinese-Chess 中国象棋初版 实现了单人双方对战、人对战电脑、开两个客户端联机对战 ```cobol 佛曰: * 写字楼里写字间，写字间里程序员； * 程序人员写程序，又拿程序换酒钱。 * 酒醒只在网上坐，酒醉还来网下眠； * 酒醉酒醒日复日，网上网下年复年。 * 但愿老死电脑间，不愿鞠躬老板前； * 奔驰宝马贵者趣，公交自行程序员。 * 别人笑我忒疯癫，我笑自己命太贱； * 不见满街漂亮妹，哪个归得程序员？ ``` ## 界面展示 ### 主菜单界面：  主界面部分代码： ```c++ #include "choosemainwindow.h" ChooseMainWindow::ChooseMainWindow(QWidget *parent) : QDialog(parent) { this->setWindowTitle("选择游戏方式"); this->setFixedSize(250,120); this->setWindowIcon(QIcon(":/images/chess.svg")); QVBoxLayout* lay = new QVBoxLayout(this); lay->addWidget(m_buttons[0] = new QPushButton("玩家自己对战")); lay->addWidget(m_buttons[1] = new QPushButton("玩家和AI对战")); lay->addWidget(m_buttons[2] = new QPushButton("双人网络对战")); /*游戏方式一: 自己和自己下棋【同一台PC机器】*/ connect(m_buttons[0], &QPushButton::clicked,[=](){ this->hide(); m_pAgainstYourself = new ChessBoard(); m_pAgainstYourself->setWindowTitle("玩家自己对战"); m_pAgainstYourself->show(); //返回主窗口 connect(m_pAgainstYourself,&ChessBoard::toMenu,[=](){ m_pAgainstYourself->close(); this->show(); }); }); /*游戏方式二: 自己和电脑下棋【同一台PC机器】*/ connect(m_buttons[1], &QPushButton::clicked,[=](){ this->hide(); m_pRobotGame = new RobotGame(); m_pRobotGame->setWindowTitle("玩家和AI对战"); m_pRobotGame->show(); //返回主窗口 connect(m_pRobotGame,&ChessBoard::toMenu,[=](){ m_pRobotGame->close(); this->show(); }); }); /*游戏方式三: 双人局域网下棋【可在局域网下不同台PC机器】*/ connect(m_buttons[2], &QPushButton::clicked,[=](){ this->hide(); QMessageBox::StandardButtons ret = QMessageBox::question(NULL, "提示", "是否作为服务器启动[选择红方]?"); bool bServer = false; if(ret == QMessageBox::Yes) bServer = true; m_pNetworkGame = new NetworkGame(bServer); m_pNetworkGame->setWindowTitle("双人网络对战"); m_pNetworkGame->show(); //返回主窗口 connect(m_pNetworkGame,&ChessBoard::toMenu,[=](){ m_pNetworkGame->close(); this->show(); }); }); } ``` ### 玩家和自己对战界面：  棋盘绘制部分代码： ```c++ void ChessBoard::paintEvent(QPaintEvent *) { QPainter painter(this); painter.setRenderHint(QPainter::Antialiasing, true);//渲染提示 int side = qMin(int(ui->centralwidget->width() - ui->rightWidget->width()), ui->label->height()); painter.scale(side / 960.0, side / 960.0); m_offset = 60; //距离界面的边距 m_distance = 90; //间距为90px m_radius = m_distance/2; //棋子半径为d/2 for(int i = 0; i <10; i++){ painter.drawLine(QPoint(m_offset, m_offset+i*m_distance), QPoint(m_offset+8*m_distance, m_offset+i*m_distance)); } for(int i=0; i<9; i++){ if(i==0 || i==8){ painter.drawLine(QPoint(m_offset+i*m_distance, m_offset), QPoint(m_offset+i*m_distance, m_offset+9*m_distance)); }else{ painter.drawLine(QPoint(m_offset+i*m_distance, m_offset), QPoint(m_offset+i*m_distance, m_offset+4*m_distance)); painter.drawLine(QPoint(m_offset+i*m_distance, m_offset+5*m_distance), QPoint(m_offset+i*m_distance, m_offset+9*m_distance)); } } painter.drawLine(QPoint(m_offset+3*m_distance, m_offset), QPoint(m_offset+5*m_distance, m_offset+2*m_distance)); painter.drawLine(QPoint(m_offset+3*m_distance, m_offset+2*m_distance), QPoint(m_offset+5*m_distance, m_offset)); painter.drawLine(QPoint(m_offset+3*m_distance, m_offset+7*m_distance), QPoint(m_offset+5*m_distance, m_offset+9*m_distance)); painter.drawLine(QPoint(m_offset+3*m_distance, m_offset+9*m_distance), QPoint(m_offset+5*m_distance, m_offset+7*m_distance)); QRect rect1(m_offset+m_distance, m_offset+4*m_distance, m_distance, m_distance); QRect rect2(m_offset+2*m_distance, m_offset+4*m_distance, m_distance, m_distance); QRect rect3(m_offset+5*m_distance, m_offset+4*m_distance, m_distance, m_distance); QRect rect4(m_offset+6*m_distance, m_offset+4*m_distance, m_distance, m_distance); painter.setFont(QFont("FangSong", m_radius * 5 / 6, 800)); painter.drawText(rect1, "楚", QTextOption(Qt::AlignCenter)); painter.drawText(rect2, "河", QTextOption(Qt::AlignCenter)); painter.drawText(rect3, "汉", QTextOption(Qt::AlignCenter)); painter.drawText(rect4, "界", QTextOption(Qt::AlignCenter)); //*******************绘画棋子******************* //绘制上次移动棋子的起止位置 if(m_isShowStep) drawLastStep(painter,m_chessSteps); for(int i = 0; i < 32; i++) drawChessPieces(painter, i); //绘制文本棋谱 drawTextStep(); } ``` ### 玩家和AI对战界面：  其实并不算是真正的AI，算法实现的是只要有可以吃到的子，就会直接吃掉，有多个可以吃掉的子，会计算各个棋子的得分，没有就随便走一步。 部分实现代码： ```c++ ChessStep *RobotGame::getBestMove() { int maxScore = -10000; ChessStep* retStep = NULL; //有可击杀的红棋子就走击杀红棋子最优的一步 // 1.看看有那些步骤可以走 QVector steps; getAllPossibleMoveStep(steps); //没有可击杀的红棋子就走最后的一步 QVector stepsAndNoKill; getAllPossibleMoveStepAndNoKill(stepsAndNoKill); //2.试着走一下 for(QVector::iterator it = steps.begin(); it!=steps.end(); it++) { ChessStep* step = *it; fakeMove(step); int score = calcScore(); //3.计算最好的局面分 unFakeMove(step); if(score > maxScore) { maxScore = score; retStep = step; } } if(retStep != NULL) return retStep; //2.试着走一下 //从这种不击杀红棋子，只是单纯移动黑棋steps里面，随机抽选一种进行下棋 int nStepsCount = stepsAndNoKill.count(); qsrand(QTime(0,0,0).secsTo(QTime::currentTime())); int temp =qrand()% nStepsCount; QVector::iterator it = stepsAndNoKill.begin(); retStep = it[temp]; if(retStep == NULL) whoWin(); return retStep; } int RobotGame::calcScore() { //enum m_emTYPE{JIANG, SHI, XIANG, MA, CHE, PAO, BING}; //黑棋分数 - 红棋分数 int redGrossScore = 0; int blackGrossScore = 0; static int chessScore[]={200, 20, 40, 60, 100, 80, 10}; for(int i=0; i<16; i++) { if(m_chessPieces[i].m_isDead) continue; blackGrossScore += chessScore[m_chessPieces[i].m_emType]; } for(int i=16; i<32; i++) { if(m_chessPieces[i].m_isDead) continue; redGrossScore += chessScore[m_chessPieces[i].m_emType]; } return (blackGrossScore - redGrossScore); } void RobotGame::getAllPossibleMoveStep(QVector &steps) { for(int id = 0; id<16; id++){ if(m_chessPieces[id].m_isDead) continue; for(int row=0; row<10; row++){
