Maz Development Directory - Cocos2dx 3.0 Callbacks

Another seemingly interesting change is to callbacks. Previously, relied on ugly macros and weird syntax to pass a callback method to an instance:

FiniteTimeAction* callback = CCCallFuncO::create(
    this, 
    callfuncO_selector(
        KDContentLayer::_switchLayer
    ), 
    screenLayer
);

However, they now migrated to one of the new awesome features of C++11, which is std::bind.

FiniteTimeAction* callback = CallFuncN::create(
    std::bind(&KDContentLayer::_switchLayer, this, screenLayer)
);
