cocos2dx 中的SEL_Callfunc,SEL_CallfuncN,SEL_CallfuncNd的用法
|
1，进入这三个源码中，可以看到这几句代码分别为 typedef void (CCobject::*SEL_SCHEDULE)(float); //函数指针，函数有一个参数float,返回类型为void typedef void (CCobject::*SEL_CallFunc)();//函数指针，函数无参数,返回类型为void typedef void (CCobject::*SEL_CallFuncN)(CCNode*)//函数指针，函数有一个参数,返回类型为void typedef void (CCobject::*SEL_CallFuncND)(CCNode*,void*);/函数指针，函数有一个参数,返回类型为void typedef void (CCobject::*SEL_CallFuncND)(CCNode*,void*);/函数指针，函数有两个参数,返回类型为void typedef void (CCobject::*SEL_CallFuncO)(CCObject*);/函数指针，函数有一个参数,返回类型为void typedef void (CCObject::SEL_MenuHandler)(CCObject*);// 函数指针，函数有一个参数，返回类型为void 2,这些都是Cocos2dx中定义的宏
#define schedule_selector(_SELECTOR) (SEL_SCHEDULE)(&_SELECTOR) #define callfunc_selector(_SELECTOR) (SEL_CallFunc)(&_SELECTOR) #define callfuncN_selector(_SELECTOR) (SEL_CallFuncN)(&_SELECTOR) #define callfuncND_selector(_SELECTOR) (SEL_CallFuncND)(&_SELECTOR) #define callfuncO_selector(_SELECTOR) (SEL_CallFuncO)(&_SELECTOR) #define menu_selector(_SELECTOR) (SEL_MenuHandler)(&_SELECTOR) 3，下面看一些经常使用的方法void Daojishi(float dt);//必须要有参数才能调用update 我们可能都会用到，如 this->schedule(schedule_selector(myTest::Daojishi)); void add(CCobject * pSender); 或者item->setTarget(menu_selector(myTest::add)); CCNode * node SEL_CallFuncND selectorND;// 函数指针 或者 CCObject *pSelectorTarget; SEL_SCHEDULE selector;
4，如果我们自己定义个回调函数，可以这样来写
void init(CCObject* _pSelectorTarget,Sel_Schedule _selector)
{
pSelectorTarget = _pSelecotrTarget.
selector = _pSelector;
}
(pSelectorTarget -> *selector) (f_time) 函数指针调用传递参数
void ArmatureSprite::ArmatureAttackcall(CCNode* _pNode1,SEL_CallFuncND _pselector1,void *_pd1,149)">CCNode* _pNode2,149)">SEL_CallFuncND _pselector2,166)">void* _pd2){
pNode1 = _pNode1; pSelector1 = _pselector1; pD1 = _pd1; pNode2 = _pNode2; pSelector2 = _pselector2; pD2 = _pd2;
_armatureBaoZha->ArmatureAttackcall(NULL,NULL, NULL,this,callfuncND_selector(BaseSpecialEffectsGetReward::HD_OpenStarBox),tempStr); }
