C++ SFML 2.2 vectors

Question

I'm just playing around with C++ SFML stuff and I kinda don't understand why my code isn't working. The thing I want to do is to draw like let's say 5, squares in Window randomly placed around the screen using vector, but I don't understand why it's not working.

This is the main game class:

#include "main_game.h"
#include "main_menu.h"

void main_game::Initialize(sf::RenderWindow* window)
{
    this->Player = new player();
    this->Player->setOrigin(this->Player->getGlobalBounds().width / 2, this->Player->getGlobalBounds().height / 2);

    this->TestObject = new testObject();
    this->TestObject->Initialize();
    this->TestObject->setOrigin(this->TestObject->getGlobalBounds().width / 2, this->TestObject->getGlobalBounds().height / 2);
}

void main_game::Update(sf::RenderWindow* window)
{
    this->Player->setPosition(sf::Mouse::getPosition(*window).x, sf::Mouse::getPosition(*window).y);
    this->Player->Update();

    if (this->Player->CheckCollision(TestObject))
    {
        this->TestObject->setColor(sf::Color::Red);
    }
    else
    {
        this->TestObject->setColor(sf::Color::Cyan);
    }

    if (sf::Keyboard::isKeyPressed(sf::Keyboard::Key::Escape))
    {
        coreState.SetState(new main_menu());
    }
}

void main_game::Render(sf::RenderWindow* window, std::vector<sf::Sprite> sprites)
{
    this->TestObject->Render(*window, sprites);

    window->draw(*this->Player);
}

void main_game::Destroy(sf::RenderWindow* window)
{
    delete this->Player;
    delete this->TestObject;
}

This is the testObject.h class

#pragma once

#include "entity.h"

class testObject : public Entity
{
public:
    testObject();
    void Initialize();
    void Render(sf::RenderWindow window, std::vector<sf::Sprite> sprites);
    void Update();
private:
    sf::RenderWindow window;
};

And this is testObject.cpp class

#include "testObject.h"

testObject::testObject()
{
    this->Load("testObject.png");
}

void testObject::Initialize()
{
    sf::Texture testObjectTexture;
    sf::Sprite testObjectSprite;

    testObjectTexture.loadFromFile("testObject.png");
    testObjectSprite.setTexture(testObjectTexture);

    std::vector<sf::Sprite> sprites(5, sf::Sprite(testObjectSprite));

    srand(time(0));

    for (unsigned int i = 0; i < sprites.size(); i++)
    {
        sprites[i].setPosition(1 + (rand() % 1024 - 32), rand() % 640 - 32);
    }
}

void testObject::Render(sf::RenderWindow window, std::vector<sf::Sprite> sprites)
{
    for (unsigned int i = 0; i < sprites.size(); i++)
    {
        window.draw(sprites[i]);
    }
}

void testObject::Update()
{
    Entity::Update();
}

The error message is

Answer 1

This specific error, (although I'm pretty sure you will have more once you fix it), probably comes from this:

void testObject::Render(sf::RenderWindow window, std::vector<sf::Sprite> sprites)

You are passing the RenderWindow by value, but it is non-copyable. Pass it by reference or pointer instead.

Answer 2

Okay, I fixed that problem, but now it's not giving me any errors, so that's good, but it is not rendering anything.
