System / Another sf::Thread topic about loading resources in background

« on: April 05, 2012, 12:40:00 pm »

Hello, i'm trying to load resources in background :

Code: [Select]

#include <SFML/Graphics.hpp>
#include <SFML/System.hpp>

void LoadResources()
{
sf::Context context;
for (int i = 0; i < 100; i++)
{
sf::Texture * texture = new sf::Texture();
texture->loadFromFile("D:/2.png");
}
}

int main()
{
sf::RenderWindow m_window(sf::VideoMode(1024, 768, 32), "Test", sf::Style::Close);
sf::Text m_text("test");
sf::Clock clock;
while (m_window.isOpen())
{
m_text.setPosition(clock.getElapsedTime().asMilliseconds() / 100, 100  );
sf::Event event;
while(m_window.pollEvent(event))
{
if (event.type == sf::Event::Closed) {
m_window.close();
}
if (event.type == sf::Event::KeyPressed) {
// key down
if (event.key.code == sf::Keyboard::Space) {
sf::Thread thread(LoadResources);
thread.launch();
}
}
}
m_window.clear();
m_window.draw(m_text);
m_window.display();
}
return 0;
}

The problem is that the main thread stops rendering while the second thread is working.
Also tried to use mutex to sync (acording to example on wiki), no changes. Am i missing something ?

Graphics / Just wondering, Intel GPU

« on: March 27, 2012, 08:07:50 pm »

Despite the problems with Intel graphics cards, was wondering if writing project without  using render to texture, will the program work on integrated video cards ?
I created a render texture, render all the graphics there, and than simply display RT texture in other sprite in window, and noticed some texture flicker (inside render texture). Is there any way to fix this, or just try to avoid using them until this problem being solved ?
