Title: Question about textures and shapes
Post by: MaeZer on May 27, 2015, 09:56:34 pm

I would like to set the texture of a RectangleShape, but I don't understand how you do it like in the documentation. Can someone tell me how to do it please? I created my texture and rectangleshape but I don't know how you actually set it. My code doesn't seem to work.

sf::Texture rectex;
rectex.loadFromFile("resources/texture");

rectangle.setTexture(rectex);

What doesn't work? What goes wrong?

You should be aware that the texture you're loading here is missing a file extension.

Oops I forgot the extension  :P Corrected it

It says after .setTexture "No suitable conversion function from sf::Texture to const sf::Texture* exists"

Ah, unlike sf::Sprite's setTexture() which takes a reference to an sf::Texture, sf::RectangleShape's setTexture() takes a pointer to an sf::Texture.

Try:

rectangle.setTexture(&rextex);

Does that fix your problem?

---

It's actually sf::Shape that takes the pointer and sf::RectangleShape is derived from that.
Not sure why Shape takes a pointer while Sprite takes a reference. For consistency, they should be the same (preferably reference) if possible.

Is there any reason why they take it differently, even though the function is used in the same way by the user?

Because shapes don't have to have a texture, thus one needs to be able to set it to NULL, while sprites always need a texture.

That makes sense. It's just confusing that they work differently.
