I have projectiles that move from the origin(player position) to where I click my mouse. They're stored as a vector of pairs, where one part is the target position(as a Vector2i), and the other is the sprite. My problem is that the sprites now don't move. Before, I only had one projectile so I converted everything - now it doesn't work.

void Fireball::draw(sf::RenderTarget& target, sf::RenderStates states) const
{
    for (const auto& projectile : fireballs)
    {
        target.draw(projectile.second);
    }
}

void Fireball::update(float dt, sf::RenderWindow* window, bool collision, bool hit, sf::Vector2f origin)
{   
    for (const auto& projectile : fireballs)
    {
        sf::Sprite temp = projectile.second;

        sf::Vector2f vectorToTarget = static_cast<sf::Vector2f>(window->mapPixelToCoords(projectile.first)) - origin;
        float distanceToTarget = sqrt(vectorToTarget.x * vectorToTarget.x + vectorToTarget.y * vectorToTarget.y);

        // reset once collides or hits enemy
        if (collision || hit)
        {   
            temp.move(vectorToTarget);
            target = {};
            fireballs.pop_back();
        }
        // move projectile
        else
        {
            sf::Vector2f moveDirection = vectorToTarget / distanceToTarget;
            temp.move(moveDirection * moveSpeed);
        }
    }
}

void Fireball::mouseClicked(sf::Event event, sf::RenderWindow* window, sf::Vector2f origin)
{
    if (event.key.code == sf::Mouse::Left && fireballs.size() <= 5)
    {
        projectile.setPosition(origin);
        target = sf::Mouse::getPosition(*window);
        fireballs.push_back(std::make_pair(target, projectile));
    }
}
