Python游戏开发之《人机大战象棋》-附完整源码-python教程

今天给大家带来的是人机大战的象棋

中国象棋

首先绘制一下棋盘，看看样子：

绘制棋盘：


class Board(QLabel):'''棋盘坐标与屏幕坐标类似，左上角为 (0, 0)，右下角为 (8, 9)'''BOARD = str(dirpath / u"images/board.png")MARK = str(dirpath / u"images/mark.png")CHECK = str(dirpath / u"images/check.png")FAVICON = str(dirpath / u"images/black_bishop.png")IMAGES = {Chess.R: str(dirpath / 'images/red_rook.png'),Chess.N: str(dirpath / 'images/red_knight.png'),Chess.B: str(dirpath / 'images/red_bishop.png'),Chess.A: str(dirpath / 'images/red_advisor.png'),Chess.K: str(dirpath / 'images/red_king.png'),Chess.C: str(dirpath / 'images/red_cannon.png'),Chess.P: str(dirpath / 'images/red_pawn.png'),Chess.r: str(dirpath / 'images/black_rook.png'),Chess.n: str(dirpath / 'images/black_knight.png'),Chess.b: str(dirpath / 'images/black_bishop.png'),Chess.a: str(dirpath / 'images/black_advisor.png'),Chess.k: str(dirpath / 'images/black_king.png'),Chess.c: str(dirpath / 'images/black_cannon.png'),Chess.p: str(dirpath / 'images/black_pawn.png'),}ANIMATION_DURATION = 280flags = QtCore.Qt.WindowMinimizeButtonHint | QtCore.Qt.WindowCloseButtonHintsignal_class = BoardSignaldef __init__(self, parent=None, callback=None):super().__init__(parent=parent)self.csize = 60self.board_image = QtGui.QPixmap(self.BOARD)if parent is None:self.setWindowIcon(QtGui.QIcon(self.FAVICON))self.setWindowTitle(u"Chinese Chess")# self.setWindowFlags(self.flags)# https://www.mfitzp.com/tutorials/packaging-pyqt5-pyside2-applications-windows-pyinstaller/app = QtWidgets.QApplication.instance()if app:app.setWindowIcon(QtGui.QIcon(self.FAVICON))if os.name == 'nt':logger.info("set model id")ctypes.windll.shell32.SetCurrentProcessExplicitAppUserModelID(f'StevenBaby.Chess.{VERSION}')self.setObjectName(u"Board")self.setScaledContents(True)self.animate = QtCore.QPropertyAnimation(self, b'geometry', self)self.resize(self.csize * Chess.W, self.csize * Chess.H)for chess, path in self.IMAGES.items():self.IMAGES[chess] = QPixmap(path)mark = QPixmap(self.MARK)# 棋盘起始标记self.mark1 = QLabel(self)self.mark1.setPixmap(mark)self.mark1.setScaledContents(True)self.mark1.setVisible(False)# 棋盘落子标记self.mark2 = QLabel(self)self.mark2.setPixmap(mark)self.mark2.setScaledContents(True)self.mark2.setVisible(False)check = QPixmap(self.CHECK)# 将军棋子标记self.mark3 = QLabel(self)self.mark3.setPixmap(check)self.mark3.setScaledContents(True)self.mark3.setVisible(False)self.signal = self.signal_class()self.signal.refresh.connect(self.refresh)self.labels = mat(zeros((Chess.W, Chess.H,)), dtype=QtWidgets.QLabel)self.board = mat(zeros((Chess.W, Chess.H,)), dtype=int)self.fpos = Noneself.tpos = Noneself.check = Noneself.reverse = Falseself.update()self.callback = callbackdef setBoard(self, board, fpos=None, tpos=None):# 设置 棋盘 board，以及该步，的棋子从哪儿 fpos，到哪儿 tpos# 由于 该函数可能在多个线程中调用，所以下面触发 signal.refresh# QT 会自动将刷新棋盘的重任放到主线程去做# 如果直接在非主线程调用 refresh 函数，程序可能莫名其妙的死掉。self.board = boardself.fpos = fposself.tpos = tposself.signal.refresh.emit()

这个主要是绘制棋盘和棋盘中棋子移动产生的回调。
