Initialized property CCArray is still NULL after new CCArray

I have in scene class property in private section like 

private:
CCArray* objects;

and in init I initialize

objects = new CCArray();

but when I put breakpoint in line below objects is NULL and I don't know why. It crashes when I call objects->count(); Why I cannot initialize property ?

Solution

  • you have tagged this post with cocos2d-x 3.0. Array has changed in cocos2d-x-3.0.

    Initialize :

    cocos2d::Vector<cocos2d::Sprite *> _bullets;

    Populate:

    //   add a bullet
Sprite *bullet = Sprite::create("circle.png")
this->_bullets.pushBack(bullet);  //  retains bullet

    Looping:

    //  loop through bullets
for (auto bullet: this->_bullets)
{
    //  do something with bullet.
    //  no need to cast in this case
    if (bullet->getPositionX() > 160)
    {
        //  ...
    }
}

    Erasing :

    this->_bullets->removeObject(bullet);
