cocos2dx3.2 从引擎中学到的一招，创建新类，构造函数和虚析构函数都应该是保护类型

#include <iostream>

#include <vector>

using namespace std;

class Node

{

public:

static Node* create();

void autorelease();

protected:

Node();

virtual bool init();

virtual ~Node();

};

void Node::autorelease()

{

delete this;

}

Node* Node::create()

{

auto sp = new Node();

if(sp && sp->init())

{

}

else

{

delete sp;

}

return sp;

}

Node::Node()

{

}

Node::~Node()

{

cout << "the Node is destructed" << endl;

}

bool Node::init()

{

return true;

}

class Player : public Node

{

public:

static Player* create();

protected:

Player();

virtual ~Player();

virtual bool init();

};

Player::Player()

{

}

Player::~Player()

{

cout << "the player is destructed" << endl;

}

Player* Player::create()

{

auto sp = new Player();

if(sp && sp->init())

{

}

else

{

delete sp;

}

return sp;

}

bool Player::init()

{

return true;

}

int main()

{

auto sp = Player::create();

sp->autorelease();

return 0;

}

结果输出：

the player is destructed

the Node is destructed

Program ended with exit code: 0
