Cocos2Dx_3,10版本定时器

我接触最多的是：schedule(schedule_selector(jewelsGrid::afterSwap));

schedule_selector函数源码为：

typedef void (Ref::*SEL_CallFunc)();
typedef void (Ref::*SEL_CallFuncN)(Node*);
typedef void (Ref::*SEL_CallFuncND)(Node*, void*);
typedef void (Ref::*SEL_CallFuncO)(Ref*);
typedef void (Ref::*SEL_MenuHandler)(Ref*);
typedef void (Ref::*SEL_SCHEDULE)(float);


#define CC_CALLFUNC_SELECTOR(_SELECTOR) static_cast<cocos2d::SEL_CallFunc>(&_SELECTOR)
#define CC_CALLFUNCN_SELECTOR(_SELECTOR) static_cast<cocos2d::SEL_CallFuncN>(&_SELECTOR)
#define CC_CALLFUNCND_SELECTOR(_SELECTOR) static_cast<cocos2d::SEL_CallFuncND>(&_SELECTOR)
#define CC_CALLFUNCO_SELECTOR(_SELECTOR) static_cast<cocos2d::SEL_CallFuncO>(&_SELECTOR)
#define CC_MENU_SELECTOR(_SELECTOR) static_cast<cocos2d::SEL_MenuHandler>(&_SELECTOR)
#define CC_SCHEDULE_SELECTOR(_SELECTOR) static_cast<cocos2d::SEL_SCHEDULE>(&_SELECTOR)


// Deprecated
#define callfunc_selector(_SELECTOR) CC_CALLFUNC_SELECTOR(_SELECTOR)
#define callfuncN_selector(_SELECTOR) CC_CALLFUNCN_SELECTOR(_SELECTOR)
#define callfuncND_selector(_SELECTOR) CC_CALLFUNCND_SELECTOR(_SELECTOR)
#define callfuncO_selector(_SELECTOR) CC_CALLFUNCO_SELECTOR(_SELECTOR)
#define menu_selector(_SELECTOR) CC_MENU_SELECTOR(_SELECTOR)
#define schedule_selector(_SELECTOR) CC_SCHEDULE_SELECTOR(_SELECTOR)

NS_CC_END

可以看出来，schedule_selector是一个转换的，

#define schedule_selector(_SELECTOR) CC_SCHEDULE_SELECTOR(_SELECTOR)

#define CC_SCHEDULE_SELECTOR(_SELECTOR) static_cast<cocos2d::SEL_SCHEDULE>(&_SELECTOR)

typedef void (Ref::*SEL_SCHEDULE)(float);

上面三行代码，第一行表示把括号里的东西转换成第二行里面，static_cast<cocos2d::SEL_SCHEDULE>的格式，并且这个函数要满足第三行里面float，要有时间，一般为（float dt）。
