cocos2dx《單機鬥地主》源碼解剖之八 電腦玩家出牌與跟牌（結束）

標籤：

上一篇文章對玩家手中的牌進行分析歸類，下面就該實現電腦玩家出牌與跟牌的策略了。首先我們來看看出牌的策略，代碼如下：

void GameScene::update(float delta){    switch (m_iState)    {        case 0:            SendPk();            break;        case 1:            schedule(schedule_selector(GameScene::Call),1);            break;        case 2:            scheduleOnce(schedule_selector(GameScene::OutCard),0.5);            break;        case 3:            IsShengLi();            break;        default:            break;    }}

首先解釋下該函數，本函數為一個迴圈，每幀被調用一次。我們看一下標頭檔裡m_iState的注釋：

int m_iState;//目前狀態 ，0：發牌狀態 1：叫地主狀態 2：出牌狀態 3：結果狀態

很明顯，出牌和跟牌策略就在狀態2,該函數延時0.5秒出牌。我們接下來看下OutCard函數的策略：

void GameScene::OutCard(float delta){    switch (m_iOutCard%3)    {        case 0:            m_chuPaiMenu->setVisible(true);//顯示出牌菜單，包括”不出“，”出牌“            m_typeTem = PaiDuanPaiXing();//獲得玩家出的牌的牌型，這個函數在cocos2dx《單機鬥地主》源碼解剖之六 玩家（人）的出牌中有解釋。            if(!m_npcOne->getIsOutPk() && !m_npcTwo->getIsOutPk())//如果兩個電腦玩家沒出過牌，設”不出“按鈕不可點，反應則然。                ((CCMenuItemFont *)m_chuPaiMenu->getChildByTag(0))->setEnabled(false);            else                ((CCMenuItemFont *)m_chuPaiMenu->getChildByTag(0))->setEnabled(true);            //出牌            if(!m_npcOne->getIsOutPk() && !m_npcTwo->getIsOutPk())            {                //清除所有出的牌                ClearOutPk();//下面貼代碼                if (m_typeTem != ERROR_CARD)//ERROR_CARD為錯誤的牌型                    ((CCMenuItemFont *)m_chuPaiMenu->getChildByTag(1))->setEnabled(true);                else                    ((CCMenuItemFont *)m_chuPaiMenu->getChildByTag(1))->setEnabled(false);            }            else //跟牌            {                if(m_arrPlayerOut->count() != 0)                {                    Poker* pk = (Poker*)m_arrGenPk->objectAtIndex(0);//要跟的牌                    Poker* pk1 = (Poker*)m_arrPlayerOut->objectAtIndex(0);//玩家出的牌                    if(m_typeTem == m_type && pk1->getNum()>pk->getNum() || (m_typeTem==BOMB_CARD && m_type!=BOMB_CARD))//m_type為跟的牌的牌型                        ((CCMenuItemFont *)m_chuPaiMenu->getChildByTag(1))->setEnabled(true);                    else                        ((CCMenuItemFont *)m_chuPaiMenu->getChildByTag(1))->setEnabled(false);                }                else                    ((CCMenuItemFont *)m_chuPaiMenu->getChildByTag(1))->setEnabled(false);            }                        break;        case 1:            m_chuPaiMenu->setVisible(false);            if(!m_player->getIsOutPk() && !m_npcOne->getIsOutPk())            {                //清除所有出的牌                ClearOutPk();                NpcOutPoker(m_npcTwo,m_arrGenPk,m_npcTwoOut);//電腦出牌策略，函數下面解釋。            }            else                NpcGenPoker(m_npcTwo,m_arrGenPk ,m_npcTwoOut);//電腦跟牌策略，函數下面解釋。            PlayerOutPaiXu(m_arrGenPk);//對要跟的牌進行排序，該函數在cocos2dx《單機鬥地主》源碼解剖之六 玩家（人）的出牌有解釋。            PlayerOutPaiXu(m_npcTwoOut->getArrPk());//對電腦玩家出的牌進行排序            m_npcTwoOut->updatePkWeiZhi();//更新位置            m_npcTwo->updatePkWeiZhi();//同上            ++m_iOutCard;            if(IsOutPkFinish())//判斷遊戲是否結束，下面解釋。                m_iState = 3;            break;        case 2:            if(!m_player->getIsOutPk() && !m_npcTwo->getIsOutPk())            {                //清除所有出的牌                ClearOutPk();                NpcOutPoker(m_npcOne,m_arrGenPk,m_npcOneOut);            }            else                NpcGenPoker(m_npcOne,m_arrGenPk,m_npcOneOut);            PlayerOutPaiXu(m_arrGenPk);            PlayerOutPaiXu(m_npcTwoOut->getArrPk());            m_npcOneOut->updatePkWeiZhi();            m_npcOne->updatePkWeiZhi();            ++m_iOutCard;            if(IsOutPkFinish())                m_iState = 3;            break;        default:            break;    }}

首先介紹一下這個狀態機器，我們看標頭檔對m_iOutCard變數的定義：int m_iOutCard;//論到誰出牌，0為玩家出牌與跟牌的策略，1和2為電腦玩家出牌與跟牌的策略。他們的意義已在代碼裡添加註釋。

在上面代碼中你一定發現了有些令人費解的函數（ClearOutPk()，NpcOutPoker(m_npcTwo,m_arrGenPk,m_npcTwoOut)，NpcGenPoker(m_npcTwo,m_arrGenPk ,m_npcTwoOut)，IsOutPkFinish()），下面一一解釋：

ClearOutPk()的代碼：

void GameScene::ClearOutPk(){    CCObject* object;

//清除玩家出的牌

    CCARRAY_FOREACH(m_playerOut->getArrPk(),object){        Poker* pk = (Poker*)object;        pk->setVisible(false);    }    m_playerOut->getArrPk()->removeAllObjects();

//清除電腦玩家出的牌    CCARRAY_FOREACH(m_npcTwoOut->getArrPk(),object){        Poker* pk = (Poker*)object;        pk->setVisible(false);    }    m_npcTwoOut->getArrPk()->removeAllObjects();

//同上    CCARRAY_FOREACH(m_npcOneOut->getArrPk(),object){        Poker* pk = (Poker*)object;        pk->setVisible(false);    }    m_npcOneOut->getArrPk()->removeAllObjects();    this->getChildByTag(NpcOneBuChu)->setVisible(false);    this->getChildByTag(NpcTwoBuChu)->setVisible(false);}

NpcOutPoker(m_npcTwo,m_arrGenPk,m_npcTwoOut) 電腦出牌策略：

電腦出牌策略我這裡只是簡單的判斷，打出排在第一位置牌值最小的牌型。

void GameScene::NpcOutPoker(Player* npc,CCArray* out,Player* out1){    //隱藏上一次出的牌    CCObject* object;    CCARRAY_FOREACH(out1->getArrPk(),object){ //out1為上一次出的牌        Poker* pk = (Poker*)object;        pk->setVisible(false);    }    out1->getArrPk()->removeAllObjects();    //打出牌值最小的一個牌型，也就是排在第一位置的牌型    PaiXing px = npc->m_vecPX.front();    out->removeAllObjects();    //三條出牌原則    if(px.type == THREE_CARD){        stable_sort(npc->m_vecPX.begin(),npc->m_vecPX.end(),isShorter1);        m_type = THREE_CARD;        //帶單        for(std::vector<PaiXing>::iterator iter=npc->m_vecPX.begin();iter!=npc->m_vecPX.end();++iter)        {            //除非只剩兩手牌，否則不能帶王和2            Poker* pk = iter->vec.front();            if(pk->getNum() >= Er && npc->m_vecPX.size() != 1)                break;            if(iter->type == SINGLE_CARD)            {                out1->getArrPk()->addObject(iter->vec.front());                out->addObject(iter->vec.front());                npc->getArrPk()->removeObject(iter->vec.front());                npc->m_vecPX.erase(iter);                m_type = THREE_ONE_CARD;                break;            }        }        //帶雙        if(out1->getArrPk()->count() == 0)        {            for(std::vector<PaiXing>::iterator iter=npc->m_vecPX.begin();iter!=npc->m_vecPX.end();++iter)            {                //除非只剩兩手牌，否則不能帶王和2                Poker* pk = iter->vec.front();                if(pk->getNum() >= Er && npc->m_vecPX.size() != 1)                    break;                if(iter->type == DOUBLE_CARD)                {                    for(std::vector<Poker*>::iterator it=iter->vec.begin();it!=iter->vec.end();++it)                    {                        out1->getArrPk()->addObject(*it);                        out->addObject(*it);                        npc->getArrPk()->removeObject(*it);                    }                    npc->m_vecPX.erase(iter);                    m_type = THREE_TWO_CARD;                    break;                }            }        }    }    //三順出牌原則    if(px.type == AIRCRAFT_CARD){        //有足夠的單就帶單        stable_sort(npc->m_vecPX.begin(),npc->m_vecPX.end(),isShorter1);        m_type = AIRCRAFT_CARD;        if(GetNpcPxNum(npc,SINGLE_CARD) >= px.vec.size()/3)        {            int num=0;            for (std::vector<PaiXing>::iterator it=npc->m_vecPX.begin(); it!=npc->m_vecPX.end()&&num<px.vec.size()/3;)            {                if(it->type == SINGLE_CARD)                {                    ++num;
