We are migrating issue tracker of Cocos2d-x Project to Github, please create new issue there. Thanks.
Remove CREATE_FUNC macro, use Template
Remove CREATE_FUNC macro, use Template
Refactor #3096 [Closed]
UPDATED Constructor argument list fixed: I forget to pass argument list the object contructor.
template< typename T, typename ...Args >
T * createCC( Args&& ... args ){
T * pRet = new T(std::forward(args)...);
if( pRet and pRet->init() ){
pRet->autorelease();
}else if( pRet ){
delete pRet;
pRet = nullptr;
}
return pRet;
}
Redmine issue system is closed, we are using github issue system instead.

With c++11 it will be better to have a unique create function using templates instead of use a CREATE_FUNC macro in each class.
namespace cocos2d{ template< typename T > T * create(){ T * pRet = new T; if( pRet and pRet->init() ){ pRet->autorelease(); }else if( pRet ){ delete pRet; pRet = nullptr; } return pRet; } }And then, we change from:
@ MyNewScene * scene = MyNewScene::create();@
to:
@ auto scene = cocos2d::create<MyNewScene>();@
And we remove the need for remember to add CREATE_FUN(MyNewScene); in the class.
We also can forward template parameters to allow parameters in the Object constructor:
template< typename T, typename ...Args > T * createCC(){ T * pRet = new T(std::forward...); if( pRet and pRet->init() ){ pRet->autorelease(); }else if( pRet ){ delete pRet; pRet = nullptr; } return pRet; }
