将SEL_CallFuncO添加到CCArray

Question

I have the following code in my cocos2d-X application that is not compiling

   SEL_CallFuncO func1 =callfunc_selector(BPBasketLayer::addSingleNumberBasket);
   SEL_CallFuncO func2 =callfunc_selector(BPBasketLayer::addSpawnPowerUp);
   CCArray *arr=CCArray::create();
   arr->addObject(func1);
   arr->addObject(func2);

Now this is giving me an error ? What am i doing wrong ?

Kind Regards

Without knowing what the error is, it looks like you're using the wrong callfunc_selector based on how you are instantiating func1 and func2 . I think you want to use callfuncO_selector since it takes a CCObject* .

From CCObject.h :

typedef void (CCObject::*SEL_CallFuncO)(CCObject*);

#define callfuncO_selector(_SELECTOR) (SEL_CallFuncO)(&_SELECTOR)

Edit:

You will need to follow what Vikas suggested in the comments and use a std::vector to house the function pointers since CCArray is for CCObject derived classes only. So something like this:

std::vector <SEL_CallFuncO> func_ptr_array;

func_ptr_array.push_back(callfuncO_selector(BPBasketLayer::addSingleNumberBasket));

func_ptr_array.push_back(callfuncO_selector(BPBasketLayer::addSpawnPowerUp));
