依照游戏规则,发完牌下面就该叫地主了,首先从玩家(人)开始叫地主,下一回合所有玩家(包括电脑玩家)按逆时针顺序叫地主。我们来看一下叫地主的模块:

void GameScene::Call(float dt){  
    //是否都叫过地主  
    if(!m_player->getCall() || !m_npcOne->getCall() || !m_npcTwo->getCall())  
    {  
        m_iCallTime%=3;  
        switch (m_iCallTime)  
        {  
        case 0://玩家选择地主分数  
            m_menu->setVisible(true);  
            if (m_bCall[0])//1分  
            {  
                CCMenuItemFont* itemFont = (CCMenuItemFont*)m_menu->getChildByTag(1);  
                itemFont->setEnabled(false);  
            }  
            else  
            {  
                CCMenuItemFont* itemFont = (CCMenuItemFont*)m_menu->getChildByTag(1);  
                itemFont->setEnabled(true);  
            }  
            if (m_bCall[1])//2分  
            {  
                CCMenuItemFont* itemFont = (CCMenuItemFont*)m_menu->getChildByTag(2);  
                itemFont->setEnabled(false);  
            }  
            else  
            {  
                CCMenuItemFont* itemFont = (CCMenuItemFont*)m_menu->getChildByTag(2);  
                itemFont->setEnabled(true);  
            }  
            if (m_bCall[2])//3分  
            {  
                CCMenuItemFont* itemFont = (CCMenuItemFont*)m_menu->getChildByTag(3);  
                itemFont->setEnabled(false);  
            }  
            else//不叫  
            {  
                CCMenuItemFont* itemFont = (CCMenuItemFont*)m_menu->getChildByTag(3);  
                itemFont->setEnabled(true);  
            }  
            break;  
        case 1://电脑1选择地主分数  
            ++m_iCallTime;  
            NpcCall(m_npcTwo,m_npcOne);//电脑玩家叫地主  
            ShowFenShu(ccp(m_npcTwo->getPoint().x-88,m_npcTwo->getPoint().y),m_npcTwo->getCallNum());  
            break;  
        case 2://电脑2选择地主分数  
            ++m_iCallTime;  
            NpcCall(m_npcOne,m_npcTwo);  
            ShowFenShu(ccp(m_npcOne->getPoint().x+88,m_npcOne->getPoint().y),m_npcOne->getCallNum());  
            break;  
        }  
    }  
    else//判断谁是地主并把三张牌给他  
    {  
        //如果都没叫地主,把地主给一开始选地主那个  
        if(m_player->getCallNum() == 0 && m_npcOne->getCallNum() == 0 && m_npcTwo->getCallNum() == 0)  
        {  
            switch (m_iCall%3)

            case 0:  
                m_player->setCallNum(3);  
                break;  
            case 1:

                break;  
            default:  
                break;  
            }  
        }  
        //谁的值大谁当地主  
        CCObject* object;  
        if(m_player->getCallNum() > m_npcOne->getCallNum() && m_player->getCallNum() > m_npcTwo->getCallNum()){

            }

            m_Three->getArrPk()->addObjectsFromArray(arrTem);  
            m_Three->updatePkWeiZhi();

                m_iOutCard = 2;  
            }  
            m_Three->getArrPk()->removeAllObjects();  
            m_Three->getArrPk()->addObjectsFromArray(arrTem);  
            m_Three->updatePkWeiZhi();  
            //重新分拆牌  
            m_npcOne->m_vecPX.clear();  
            m_npcOne->updatePkWeiZhi();  
            FenChaiNpcPai(m_npcOne);  
            //显示地主标签  
            m_lableDiZhu->setPosition(npcOneDiZhuLablePt);  
            m_lableDiZhu->setVisible(true);  
        }  
        if(m_npcTwo->getCallNum() > m_npcOne->getCallNum() && m_npcTwo->getCallNum() > m_player->getCallNum()){  
            CCArray* arrTem = CCArray::create();

        }

        ++m_iCall;  
        m_iCallTime = m_iCall;  
        unschedule(schedule_selector(GameScene::Call));  
        //选定地主后显示三张牌  
        CCARRAY_FOREACH(m_Three->getArrPk(),object){  
            Poker* pk = (Poker*)object;  
            pk->showFront();  
        }  
        //移除叫地主分数的显示  
        this->removeChildByTag(FenShu);  
        this->removeChildByTag(FenShu);  
        this->removeChildByTag(FenShu);  
        //使主玩家的牌为可点击状态  
        CCARRAY_FOREACH(m_player->getArrPk(),object){  
            Poker* pk = (Poker *)object;  
            pk->setDianJi(true);  
        }  
    }  
}

       上面判断其实很简单:首先判断各玩家是否都已经叫分,如果是就判断谁是斗地主并把三张牌给他,如果都没有叫斗地主的话,我这里的逻辑是把斗地主判给第一个叫分的玩家。


       接下来我们看看电脑玩家是如何叫分的,为了简单,我让电脑玩家随机选择分数,代码如下:

void GameScene::NpcCall(Player* npc,Player* npc1){  

    int i = rand()%4;  

    if(i == 3) //3表示不叫  

    {  

        npc->setCall(true);//设置已叫地主  

        npc->setCallNum(0);//分数设置为0  

    }  

    else  

    {  

        while (m_bCall[i] == true)//bool m_bCall[3];分数是否被叫 m_bCall[0]:1分 m_bCall[1]:2分 m_bCall[2]:3分  

            i = rand()%3; //重新选择分数  

        m_bCall[i] = true;  

        npc->setCall(true);  

        npc->setCallNum(i+1);  

        //如果叫3分,设置其他玩家已叫地主状态  

        if(i == 2)  

        {  

            m_player->setCall(true);  

            npc1->setCall(true);  

        }  

    }  

}
