Bonjour,

j'ai trouvé un tuto de sfml:
https://fr.sfml-dev.org/tutorials/2....-events-fr.php

L'auteur y a mit du code qui ne compile pas:

Code :

int main(){
  sf::Window window(sf::VideoMode(200,200),"exemple-event",sf::Style::Default);
  sf::Event event;
  while(window.isOpen())
    while(window.pollEvent(event))
      switch(event.type){
      case sf::Event::Closed:

une idée?

[ternel]

C'est parce que tu n'as pas la même version que lui.

Au passage, je t'invite à regarder du coté du "gamedev framework" (le github), qui est un remake de la sfml avec plus de fonctionnalités. L'auteur estimait que les mainteneurs de la sfml sont trop rétrograde (notamment sur le C++ moderne).

Merci pour la réponse

Je vais voir ça.

Salut,

C'est parce que tu n'as pas la même version que lui.

Ou qu'il manque un entête, peut-être #include <SFML/Window/Event.hpp>

Ton lien c'est un exemple pour la version 2.6, et la version actuelle est la 2.6.1, donc à part un problème de configuration ou de dépendance il n'y a rien qui explique ton échec de compilation. Sinon, essaye les exemples fournis directement avec la lib.

que pensez-vous de SDL2?
