今日游戏更新，大家好，我是木木子，每天都给大家更新最好玩的游戏！关注我，从此你再也不用去费力找游戏了！

最热门最好玩的Python游戏点击即玩！

今天推荐的游戏是五子棋小游戏——人机对战、联机对战皆可！

你是否还记得？中学时代和同桌下过的五子棋？

​

这样下棋只怕是会被打！​！！！我怀疑他开挂了，并且找到了证据。

首先准备好需要的图片等素材部分如下：

好了！直接上代码吧——设置游戏开始界面：

class gameStartUI(QWidget):
    def __init__(self, parent=None, **kwargs):
        super(gameStartUI, self).__init__(parent)
        self.setFixedSize(760, 650)
        self.setWindowTitle('五子棋游戏对战')
        self.setWindowIcon(QIcon(cfg.ICON_FILEPATH))
        # 背景图片
        palette = QPalette()
        palette.setBrush(self.backgroundRole(), QBrush(QPixmap(cfg.BACKGROUND_IMAGEPATHS.get('bg_start'))))
        self.setPalette(palette)
        # 按钮
        # --人机对战
        self.ai_button = PushButton(cfg.BUTTON_IMAGEPATHS.get('ai'), self)
        self.ai_button.move(250, 200)
        self.ai_button.show()
        self.ai_button.click_signal.connect(self.playWithAI)
        # --联机对战
        self.online_button = PushButton(cfg.BUTTON_IMAGEPATHS.get('online'), self)
        self.online_button.move(250, 350)
        self.online_button.show()
        self.online_button.click_signal.connect(self.playOnline)
    '''人机对战'''
    def playWithAI(self):
        self.close()
        self.gaming_ui = playWithAIUI(cfg)
        self.gaming_ui.exit_signal.connect(lambda: sys.exit())
        self.gaming_ui.back_signal.connect(self.show)
        self.gaming_ui.show()
    '''联机对战'''
    def playOnline(self):
        self.close()
        self.gaming_ui = playOnlineUI(cfg, self)
        self.gaming_ui.show()

'''run'''
if __name__ == '__main__':
    app = QApplication(sys.argv)
    handle = gameStartUI()
    font = QFont()
    font.setPointSize(12)
    handle.setFont(font)
    handle.show()
    sys.exit(app.exec_())

效果如下：
