Merci du conseil, j'ai trouvé pourquoi les statisiques ne s'affichaient pas.
Pour le background, je ne comprends pas.
#include <iostream>
#include <SFML\Graphics.hpp>
const sf::Time TimePerFrame = sf::seconds(1.f / 60.f);
int main()
{
sf::RenderWindow win(sf::VideoMode(640, 480), "Shoot'em up !");
sf::View mWorldView(win.getDefaultView());
sf::FloatRect mWorldBounds(0.f, 0.f, mWorldView.getSize().x, 2000.f);
sf::Vector2f mSpawnPosition(mWorldView.getSize().x / 2.f,
mWorldBounds.height - mWorldView.getSize().y / 2.f);
sf::Clock clock;
sf::Time timeSinceLastUpdate = sf::Time::Zero;
while (win.isOpen())
{
// Render -----------------------------------------------------------
win.clear();
sf::Texture texture;
texture.loadFromFile("Textures/Desert.png");
sf::IntRect textureRect(mWorldBounds);
texture.setRepeated(true);
sf::Sprite bg_sprite(texture);
// Prepare the view
mWorldView.setCenter(mSpawnPosition); //Si je commente le background s'affiche
win.setView(mWorldView);
win.draw(bg_sprite);
win.setView(win.getDefaultView());
win.display();
//-----------------------------------------------------------------------
}
return 0;
