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();
}

This specific error, (although I'm pretty sure you will have more once you fix it), probably comes from this:
You are passing the
RenderWindow
by value, but it is non-copyable. Pass it by reference or pointer instead.
