General discussions / GUI - Whats the best os most used GUI

« on: November 28, 2010, 06:06:28 am »

I want a gui that is easy to use, and is easy to change the theme/skin/template.

Like the GUI of game M.A.R.S., made with sfml.

I want a GUI that do all of that game do, or all that a game need. GUI based on images.

Window / SFML 2 - Bug when exit

« on: November 28, 2010, 06:04:46 am »

The code of my basic test is:

Code: [Select]


#include <stdlib.h>
#include <iostream>
#include <SFML/Graphics.hpp>
#include <SFML/System.hpp>
#include <SFML/Window.hpp>


int main(int argc, char** argv)
{
sf::RenderWindow Game(sf::VideoMode(800, 600, 32), "Teste");
   
while (Game.IsOpened())
{

sf::Event event;
        while (Game.GetEvent(event)) {

            if (event.Type == sf::Event::Closed)
                Game.Close();
            if ((event.Type == sf::Event::KeyPressed) && (event.Key.Code == sf::Key::Escape))
                Game.Close();
        }

Game.Display();
        Game.Clear();

}

    return EXIT_SUCCESS;
}



Is only you create a new project with VS 2008 and SFML 2.

Project type: Console

Put this code on main.cpp.

Compile and run.

Press ESC or close the window.

You will get the error on IDE:



You will get the error executing out of IDE:



Its all details.

Graphics / Problem with tiles and performance

« on: December 14, 2008, 02:48:36 pm »

I have the same performance problem here:

http://www.sfml-dev.org/forum/viewtopic.php?t=816&highlight=performance

In my game in SDL i do it easy , with the same logic and with floors, and this problem dont exists.

The problem is on DRAW method, too many DRAW call cause it.

Where is the problem? SFML ? Me and the author of this post? The creator?

I try the same with on a new pc, on SVN release, and the problem is the same.

General / Several performance problem!!!

« on: December 14, 2008, 02:21:55 pm »

Im creating a gui lib for my game with sfml:

So, i have created the button and textbox, and if fully perfect.

So, im creating now the window class, that will create a window on screen.

But when i will draw the parts of the window, the problem occurr, too many memory is used and the game is so slowly...too slowly...

But, if i comment the lines that draw the sprite(sprite->draw), the game run normals, with good performance, with no problem.

The code is:

Code: [Select]

General / Portugues Keyboard - Support

« on: December 12, 2008, 11:46:50 am »

Dont need more, i have solved.

But u can try it:

Code: [Select]



wstring test;
test = L"coração";  //  <-error

sf::String textBox;
sf::Font font;

if (!font.LoadFromFile("dados\\fontes\\tahoma.ttf"))
{
     //failed
}

textBox.SetText(test);
textBox.SetSize(12);
textBox.SetFont(font);



Conclusion, you can put in WSTRING some portuguese letters, or if you force with cast, occur the same problem.

Solution: use only STRING on SetText.
