Question

I am new in c++ and cocos2d-x, and I have a problem.
I have a “projectile” it is CCSprite, OK, I insert it in Array:

projectile->setTag(2);

_projectiles->addObject(projectile);

But when I need it:

CCSprite* proj;
CCARRAY_FOREACH(_projectiles,proj){
  CCSprite *projectile = proj;
  ...

I have the error about “_projectiles” have CCObject inside.
Sorry for my bad English and thancks for help!

Answer 1

You have to cast proj which is stored in CCArray as CCObject* to CCSprite*:

CCSprite *projectile = static_cast<CCSprite*>(proj);

You can also you dynamic_cast in case you need runtime check that proj is actually a CCSprite:

CCSprite *projectile = dynamic_cast<CCSprite*>(proj); //will return nullptr if failes to cast
