Class Ref<T>

#include <Geode/utils/cocos.hpp>

template<class T>classRef{ ... }

A smart pointer to a managed CCObject-deriving class. Retains shared ownership over the managed instance. Releases the object when the Ref is destroyed, or assigned another object or nullptr.

Use-cases include, for example, non-CCNode class members, or nodes that are not always in the scene tree.

Template parameters

A type that inherits from CCObject.

Examples2

class MyNode : public CCNode {
protected:
     // no need to manually call retain or
     // release on this array; Ref manages it
     // for you :3
     Ref<CCArray> m_list = CCArray::create();

     bool init() {
         if (!CCNode::init())
             return false;

         // No need to do m_list = CCArray::create()
         // or m_list->retain() :3

         return true;
     }
};

// Save a child from the current layer into a menu
Ref<CCMenu> menu = static_cast<CCMenu*>(this->getChildByID("main-menu"));
         
// Remove the menu from its parent
menu->removeFromParent();
         
// Menu will still point to a valid CCMenu as long as the menu variable exist
