General / Compiling program on Linux

« on: August 09, 2013, 09:38:33 am »

I'm following the SFML 2.0 tutorial for testing a program on Linux, but I'm getting the following error. I downloaded the precompiled SFML 2.1 32bit for Linux.

command:

g++ test.o -o test -L/home/crumb/sfml2.1-dev/lib -lsfml-network
 

result:

/usr/bin/ld:/home/crumb/sfml2.1-dev/lib/libsfml-network.so: file format not recognized; treating as linker script
/usr/bin/ld:/home/crumb/sfml2.1-dev/lib/libsfml-network.so:1: syntax error
collect2: ld returned 1 exit status

Window / Re: Issue with sf::Keyboard::isPressed

« on: August 03, 2013, 10:33:52 am »

It wasn't working for the life of me earlier, but after clearing my mind playing TF2 and restarting Visual Studio it worked.

I'm working on a TCP server/client chat. I've just been reading the documentation and examples, so I have a rough approach. I have a thread each for sending information and receiving information because when I was reading input it would wait on cin.

Window / [Solved] Issue with sf::Keyboard::isPressed

« on: August 03, 2013, 09:03:38 am »

Hello I've recently been learning to use multiple threads and using sf::Keyboard for unbuffered input. The issue I'm running into is that when I press A with the following code it doesn't run the what's within the if block.

if (sf::Keyboard::isKeyPressed(sf::Keyboard::Key::A)) { // Returns false
        message_out += "a";
        std::cout << "WORKED";
}
 

But when trying this it works properly and prints "WORKED"

bool test = sf::Keyboard::isKeyPressed(sf::Keyboard::Key::A); // Returns true
    if (test == true) {
        message_out += "a";
                std::cout << "WORKED";
    }
 

Is this an issue with threads or a bug?

General / Issues with linking SFML statically?

« on: June 30, 2013, 08:30:52 am »

I have SFML linked statically, and I've done some googling on my issue. I believe it has to do with global variables, but if that's the issue how can I avoid it when the variable is a static member of the class? Any way to guarantee that it is initialized after all the linking is done?

Root.hpp

#include <SFML/Graphics.hpp>

class Root {
private:
    static sf::RenderWindow render_window;
};
 

Root.cpp

#include "Root.hpp"

sf::RenderWindow Root::render_window;

int main(int argc, char **argv) {
        //sf::RenderWindow test(sf::VideoMode(200, 200), "TEST");
        return 0;
}

I re-saved the image again and it seems to be working fine. Was not an issue with SFML I guess it had to do with the way I saved it.

The image loads fine.
Through debugging SFML gives me the value 2, 0, 1 while in Photoshop it gives me 0, 0, 0
I tried printing it out, and I'm not getting the same results. I'll look more into it.

Sorry I didn't know what you meant by a minimal example 
I still don't understand what's going on.

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

int main(int argc, char **argv) {
    sf::Image img;
    img.loadFromFile("D:/Maps/001.png");
    sf::Color tmp(img.getPixel(0, 0));
    if (tmp == sf::Color (0, 0, 0)) {
        std::cout << "Black";
    } else {
        std::cout << "Other";
    }
}

Fixed now. I went through debugging and the value of the pixel at 0, 0 returns 2, 0, 1 for getPixel(). Code below was used to test it while debugging.

uchar TileGrid::ColorToIndex(sf::Color &color) {
    return 1;
    if (color == sf::Color(2, 0, 1)) {
        return 2;
    } else if (color == sf::Color(0, 255, 0)) {
        return 1;
    } else {
        Root::SetStatus(EXIT_FAILURE);
        return 255;
    }
}

    sf::Image map;
    ImageHandler::SetImage(map, "/Data/Maps/001.png");
    for (uchar x = 0; x < map_width; ++x) {
        for (uchar y = 0; y < map_height; ++y) {
            tiles[x][y].index = ColorToIndex(map.getPixel(x, y));
            SetTile(x, y, tiles[x][y].index);
        }
    }

I'm using SFML 2.0 and the getPixel() fuction of the Image class. The function returns 2,0,1 for what I drew to be 0, 0, 0 in Photoshop. http://stackoverflow.com/questions/16601839/reading-wrong-pixel-color.
