cocos2dx《单机斗地主》源码解剖之四 玩家类的解剖

概述废话不说，直接上代码： 头文件 class Player : public CCObject{public: Player(); ~Player(); void updatePkWeiZhi();//设置牌的位置 private: CC_SYNTHESIZE(bool,m_isDiZhu,IsDiZhu);//是否为地主 CC_SYNTHESIZE(bool,m_isCall,C

废话不说，直接上代码：

这个类最主要的是 updatePkWeiZhi()，它是为了把玩家手中的牌从大到小排序并居中显示。请注意最后一块代码“改变牌的z值或牌的触摸优先级”，为什么要这么做呢？这是因为牌的顺序换了之后，底下的牌有的会覆盖到另一个牌之上，改变触摸优先级也是同理。
