Hello all,

This is my first post and I'm encountering a problem with a program I'm trying to create for a small game. What it involves is basically adding a Player onto a list using std::list.

Now, the issue with that is no matter what I do, only one of the values register so I need help to show you what is going wrong. Here is both General.h and General.cpp

First of all General.h:

 c++ Syntax (Toggle Plain Text) 
class Player
{
	public:
		int id;
		string name;
 
		void printList();
		std::list<Player*> player_list;
};
class Player
{
	public:
		int id;
		string name;

		void printList();
		std::list<Player*> player_list;
};

That all seems satisfactory with me, that class. Moving onwards we come to General.cpp:

 c++ Syntax (Toggle Plain Text) 
int main()
{
	Player *entity;
	int i = 0;
 
	while(i != 10)
	{
		entity = new Player;
		entity->id = i;
		entity->name = "Bobby";
		entity->player_list.push_back(entity);
		i++;
	}
 
	entity->printList();
	return 0;
}
 
void Player::printList()
{
	std::cout << "There are " << (int) player_list.size() << " players in the linked-list" << endl;
	return;
}
int main()
{
	Player *entity;
	int i = 0;

	while(i != 10)
	{
		entity = new Player;
		entity->id = i;
		entity->name = "Bobby";
		entity->player_list.push_back(entity);
		i++;
	}

	entity->printList();
	return 0;
}

void Player::printList()
{
	std::cout << "There are " << (int) player_list.size() << " players in the linked-list" << endl;
	return;
}

Okay so this seems decent to me and I've browsed many topics of linked-lists to come to this code. So my question to all of you is why is it only say that the list is a mere size of 1 when it should be right up to 11?

No idea, hopefully someone can assist me as soon as possible! Thanks.
