cocos2dx《单机斗地主》源码解剖之五 叫地主

概述发完牌，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

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：

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);		}	}}
