Vector inside a class. C2065 error - c++

Question

I have vector of my own objects inside a class. But when i want to do something with this vector, i have error :/
game.h
#include "renderSystem.h" //there only #include "console_color.h"
#include "level.h" //there only #include "renderSystem.h"
#include "gameObject.h"
class Game {
vector<GameObject> objects;
//something
public:
Game();
//something
};
game.cpp
void Game::initialize() {
GameObject playerObject(GameObjectType_Player);
objects.insert(objects.end(), playerObject);
//something
}
gameObject.h
#include "renderSystem.h"
#include "level.h"
class GameObject {
//something
public:
GameObject(GameObjectType _type);
GameObject() : GameObject(GameObjectType_None) {};
//something
};
And errors are (i cant give you logs, because they are on russian :/ )
C2065 at game.cpp "objects.insert"
C2143 at game.h "vector<GameObject> objects"
C2228 at game.cpp "objects.insert"
C2238 at game.h "vector<GameObject> objects"
C4430 at game.h "vector<GameObject> objects"
I checked #includes, but may be i'm stupid :/
And in every file i have #pragma once
In renderSystem and level i wrote only includes
Wtf?!
Visual studio 2015
//And i have 0:43 AM, so may be i just need to sleep :/

Answer 1

You have two issues here, one, you're not including the vector header file. The second is that the vector class is in the std:: namespace in C++. Here are two possible fixes to this.
#include <vector> /* STL vector */
#include "renderSystem.h" //there only #include "console_color.h"
#include "level.h" //there only #include "renderSystem.h"
#include "gameObject.h"
class Game {
private:
std::vector<GameObject> objects;
public:
Game();
};
Or
#include <vector> /* STL vector */
#include "renderSystem.h" //there only #include "console_color.h"
#include "level.h" //there only #include "renderSystem.h"
#include "gameObject.h"
using namespace std;
class Game {
vector<GameObject> objects;
//something
public:
Game();
//something
};
