Bonjour,
je viens de reprendre la SFMLet pour me remettre en condition j'ai coder un snake vraiment basique, mais j'aimerais savoir si il est proprement coder, et si il exploite au mieux les concepts de la POO.
Merci.
#include <iostream>
#include <SFML/Graphics.hpp>
#include "Snake.h"
#define SCREEN_WIDTH 800
#define SCREEN_HEIGHT 640
int main(int, char const**)
{
sf::RenderWindow window(sf::VideoMode(SCREEN_WIDTH, SCREEN_HEIGHT), "SFML window");
window.setFramerateLimit(60);
window.setKeyRepeatEnabled(false);
Snake snake(window, 32, 32);
while (window.isOpen())
{
snake.Move();
sf::Event event;
while (window.pollEvent(event))
{
if (event.type == sf::Event::Closed)
{
window.close();
}
snake.Update(event);
}
window.clear(sf::Color(0,162,255));
snake.Draw();
window.display();
}
return EXIT_SUCCESS;
}
