Window / Re: Creating a window in a window.
« on: March 13, 2015, 04:52:53 pm »
Arf..., linux doesn't seems to be very appropriate to create more complex api. :/ (Or is it SFML fault ?)
Now, I receive a keyreleased event even if I don't release a key, this is very annoying, I think this is related to the first bug because I don't have this problem with a single window.
And when I want to put the code to render into a thread (because the rendering time is too long with mesa opensource driver) I get the this non-sense error that I haven't called XinitThread but I've done it.
I think I'll use SDL instead of SFML to get rid of this bugs with the SFML window module but I don't know if it's possible to use opengl function manually after creating an SDL window, last time I tried the opengl function wheren't not executed.

Ok so I'll look into the source code of the opensource driver to see if I can't improve some things before Vulkan is released....

Network / Re: Crash on selector.wait() with a std::thread
« on: March 09, 2015, 07:03:28 pm »
Personally, I don't use threads anymore, even for networking, this is the source of many bugs. :/
I had a similar problem as you with std::thread, my server didn't received any messages with the UDP protocol...
Since I don't use an std::thread it works fine.
And I don't have a lot of experience in multi-thread programing, so if you haven't a good experience with multi-threading programming, I don't recommand it.
PS : And where did you add the listener to your selector ? You have to add it before your loop if you want that it works.

Graphics / Is there a way to update a render texture each time a pixel is drawn ?
« on: March 09, 2015, 06:03:11 pm »
Hi!
I have a set of faces that I want to draw, I don't want to use default opengl blending and depth test because it's a very complex scene.
I've tried to perform instanced rendering but the problem is that SFML updates the render texture each time that something is drawn and not each time that a pixel is updated with the sahder, so, I can't get the right colour for faces which overlap in my shader using instanced rendering.
So I update the render texture each time I render a face, so I do more draw calls but it's slower.
My question is simple so, isn't there a way to update the render texture each time a pixel is written on the render teture with the shader ?
I don't know opengl very well so it's why I'm asking this question.

OS version : Ubuntu LTS 14.4 (64 bits)
SFML version : SFML-master (the one from the git repository)
I've also tried with the last stable version but same problem.

And here is a code which repoduce the bug :
The second window is visible. :/ (The window which the title "test2")
int main()
{
RenderWindow window(sf::VideoMode(800, 600), "OpenGL");
RenderWindow window1(sf::VideoMode(200, 100), "test");
window1.setVisible(false);
RenderWindow window2(sf::VideoMode(200, 100), "test2");
window2.setVisible(false);
while (window.isOpen())
{
sf::Event event;
while(window.pollEvent(event)) {
if (event.type == sf::Event::Closed)
window.close();
}
window.clear();
window.display();
}
return 0;

Window / Creating a window in a window.

Hi!
I need to create a window in a window for my game. (Confirmation and message dialogs.)
So I've just created this class :
It works fine except for one point, here, I want to create two sub-windows :
I set the visibility of my sub-windows to false, so the windows shouldn't be shown, but it's not what I see.
I see a transparent window on the main window, and the title is not always the title of my sub-windows..., this is really strange. :/

It works fine except for one point, here, I want to create two sub-windows :
m_pseudoUsed = new gui::OptionPane(Vec2f(200, 200), Vec2f(200, 100), fm.getResourceByAlias("FreeSerif"),"Pseudo already used!",gui::OptionPane::TYPE::MESSAGE_DIALOG);
m_pseudoUsed->setVisible(false);
m_pseudoUsed->setEventContextActivated(false);
m_confirmInvitation = new gui::OptionPane(Vec2f(200, 200), Vec2f(200, 100), fm.getResourceByAlias("FreeSerif"),"",gui::OptionPane::TYPE::CONFIRMATION_DIALOG);
m_confirmInvitation->setVisible(false);
m_confirmInvitation->setEventContextActivated(false);
m_pseudoUsed->setVisible(false);
m_pseudoUsed->setEventContextActivated(false);
m_confirmInvitation = new gui::OptionPane(Vec2f(200, 200), Vec2f(200, 100), fm.getResourceByAlias("FreeSerif"),"",gui::OptionPane::TYPE::CONFIRMATION_DIALOG);
m_confirmInvitation->setVisible(false);
m_confirmInvitation->setEventContextActivated(false);
I set the visibility of my sub-windows to false, so the windows shouldn't be shown, but it's not what I see.
I see a transparent window on the main window, and the title is not always the title of my sub-windows..., this is really strange. :/

I've reinstalled my ubuntu and now the SFML version using xcb is compiling fine, and I've a rendering thread, with a rendering thread my FPS increase from 15 to 24!
But now, that's not all, now I've to rewrite the code of my lib with xcb. :/
And I've also to correct crash with multithreading when I update the game logic. :/
I had probably old gcc package which were still installed on my ubuntu. :/

Hmmm..., I've found why it crash, you're creating the window in the glcontext, this is very bad. :/
When I create an sf::Context into an SDL_Window, it doesn't display anything. :/
So I've to create an SDL context into each render target class. :/
