Title: transparent texture into sprite but still shows white background
Post by: geekz on August 25, 2021, 06:29:22 pm

Hi everybody,

I'm just learning SFML and I'm having a trouble to load a picture without background - my current screen is black and I'd like to put sprite at screen (the .png picture i have is transparent) but still shows white background under.
Is there any simple way to make the texture/sprite transparent?

My code:

    sf::Texture texture;
    sf::Sprite sprite;
    if (!texture.loadFromFile("spacetest2.png"))
    {
        // error...
        std::cout << "doesnt work" << std::endl;
    }
    sprite.setTexture(texture);
    window.draw(sprite);
    window.display();

I've attached pictures below:

That image doesn't have transparency, the white/grey grid is actually part of it.

Ah, so I just need to find another picture that is actually transparent and use same code as I have, that's it?

Next time when you save double check if transparancy is checked!  ;)

Made it transparant for you.
