SFML projects / My menu

« on: November 06, 2018, 04:27:08 pm »

Hi ! I just began c++ and found a Sfml tutorial and really liked it so I continued with it. Most tutorial show how to make games but i'm not much into that and more into tools so half way through the tutorial I just began to write my own codes(still referring to the tutorial alot for helps achieving and understanding what i was trying to do).

My goal is not really to finish something in particular, just to express what is inside my brain. That is why i'm not pushing to "advance" something over trying to code better as I've read alot.

I find my main function to be very hard to follow and that was the first pointer to ask for others opinion, but I would like some pointers at what i should try to work on(Not necessarily how to do it), perhaps just clues as to how I should structure the whole thing. Thanks in advance !

Here is the menu and 2 screenshots will follow. 

**Just the "quitter"(quit) menu buttons works for now as don't have any functionality to the app yet.

Graphics / Rectangle shape render from the bottom of my window

« on: November 02, 2018, 03:09:00 am »

Hi, i kinda found a way around my problem, but since all origin(I think) are suppose to be in top left corner I just dont get this one :

I was trying to draw rectangle (for menu button) from the bottom right of the window with this function :

Context :

int tailleFenetre[2] = {static_cast<int>(fenetre.getSize().x),static_cast<int>(fenetre.getSize().y)};
const int MAIN_MENU_SIZE = 4;
const int MENU_LARGEUR = 120, MENU_HAUTEUR = 40;

my function :

void buildMenu(int tailleFenetre[],string optionsMenu[],sf::Texture* ptrTexture){

    sf::RectangleShape menuButton;
    menuButton.setSize(sf::Vector2f(MENU_LARGEUR,(MENU_HAUTEUR-5)));
    menuButton.setFillColor(sf::Color(221,133,175));

    sf::RenderTexture texture1;
    if(!texture1.create(tailleFenetre[0],tailleFenetre[1]))
       
         for(int i = 0; i < MAIN_MENU_SIZE; i++){

            menuButton.setPosition(sf::Vector2f((tailleFenetre[0]-MENU_LARGEUR-5),(tailleFenetre[1]-(MENU_HAUTEUR * i)-(MENU_HAUTEUR+5))));
            texture1.draw(menuButton);
        }

    texture1.draw(menuButton);
    *ptrTexture = texture1.getTexture();
}

I thought from that i should have gotten my rectangles in the bottom right corner but they drew on top right.

and if I replace my for loop with : 

menuButton.setPosition(sf::Vector2f((tailleFenetre[0]-MENU_LARGEUR-5),5));

where menuButton.setPosition().y == 5; it draws the rectangle in bottom right.


I'm a bit confuse, can someone explain ?
