[SFML/c++14] Bug de positionnement ?
Répondre avec citation
rawable et Transform, héritage déjà présent avec Sprite, c'est pas vraiment une bonne chose là. Ta lifebar est une composition de ce qu'elle dessine, elle n'a pas à être Drawable ou Transformable. Même si je comprends la syntaxe, parce que tu vas plus vite ainsi, le concept n'est pas bon.
