Graphics / sf::RectangleShape.setFillColor() is not working

« on: September 25, 2021, 05:03:04 pm »

Hello people from the SFML community. Recently I was meddling with the library and I was trying to make an sf::RectangleShape change its color whenever I hover my mouse over it, which is something I have done before without any issues. However, this time I don't understand what seems to be going wrong.
Here is the bit of code where I change the shape's color:

void Node::update(sf::RenderWindow*& window)
{
        bool mouse_over = IsMouseOver(this->rect.getGlobalBounds(), window);

        if (mouse_over)
        {
                this->rect.setFillColor(sf::Color( //Doesn't work
                        this->color.r + 30.0f,
                        this->color.g + 30.0f,
                        this->color.b + 30.0f
                ));
                printf("r: %d, g: %d, b:%d\n",
                        rect.getFillColor().r,
                        rect.getFillColor().g,
                        rect.getFillColor().b);
        }
        else if (!mouse_over)
        {
                this->rect.setFillColor(this->color); //Doesn't work either
                printf("r: %d, g: %d, b:%d\n",
                        rect.getFillColor().r,
                        rect.getFillColor().g,
                        rect.getFillColor().b);
        }
}
 

Before anyone suggests that the order of execution is wrong, let me show you how I'm using this method:

void NodeManager::updateNodes(sf::RenderWindow*& window) //Updates every node in the nodes matrix
{
        for (auto i : nodes)
                for (auto j : i)
                        j.update(window);
}
 

void Program::update(void)
{
    nodeManager->updateNodes(window);
}
void Program::run(void)
{
    while (window->isOpen())
    {
        sf::Event event;
        while (window->pollEvent(event))
            this->events(event);
        this->update(); //Method is executed within the update method before anything is drawn to the screen
        this->draw();
    }
}
 

void Program::draw(void) //The draw method
{
    window->clear();
    //Draw things here ==============================
    nodeManager->drawNodes(window);
    //===============================================
    window->display();
}
 

I need your help, because I have no idea what the issue is. I've been trying to figure this out for a while now and I'm starting to question why I'm even doing this in the first place.
