Cocos2d-x Static Constructor Macro

gistfile1.cpp

#define STATIC_CONSTRUCTOR(className, methodPostfix, methodArgs, initArgs, constructorArgs) \
static className* create ## methodPostfix methodArgs \
{ \
className *instance = new className constructorArgs; \
if (instance && instance->init ## methodPostfix initArgs) \
{ \
instance->autorelease(); \

{ \
CC_SAFE_DELETE(instance); \
} \
return instance; \
};

// This example call:
// STATIC_CONSTRUCTOR(MyScene, WithTitle, (const char *title), (title), ())
//
// generates:
//static MyScene* createWithTitle(const char *title){
//  MyScene  *instance = new MyScene();
//  if(instance && instance->initWithTitle(title)){
//    instance->autorelease();
//  }else{
//    CC_SAFE_DELETE(instance);
//  }
//  return instance;
