DotNet / DLL issues again

« on: July 01, 2014, 09:50:17 pm »

Hi,
apparently many people had this issue but all the help Google could provide me with did not solve it for me:
I get a System.DllNotFoundException for libcsfml-graphics.so.2 when trying to create a RenderWindow for example.
I have the Assembly References set up correctly and the CSFML files are located in my /usr/ directory. I set up the file sfmlnet-graphics-2.dll.config like so:
<configuration>
   <dllmap dll="csfml-graphics-2" target="libcsfml-graphics.so.2" os="linux"/>
</configuration>

I have not found any more advice for this problem since apparently it worked for everyone else like this.

General / Tutorial Segmentation Fault

« on: September 01, 2013, 11:00:27 pm »

Hi,
I compiled the tutorial code (http://www.sfml-dev.org/tutorials/2.1/start-linux.php) on my virtual Ubuntu 12.04 32-bit machine.
However, the first line
sf::RenderWindow window(sf::VideoMode(200, 200), "SFML works!");
causes a Segmentation Fault and the process terminates.

I am using the 32-bit version for Linux of SFML 2.1.

#include <SFML/Graphics.hpp>

int main()
{
    sf::RenderWindow window(sf::VideoMode(200, 200), "SFML works!");
    sf::CircleShape shape(100.f);
    shape.setFillColor(sf::Color::Green);

    while (window.isOpen())
    {
        sf::Event event;
        while (window.pollEvent(event))
        {
            if (event.type == sf::Event::Closed)
                window.close();
        }

        window.clear();
        window.draw(shape);
        window.display();
    }

    return 0;
}

General / Installing SFML 2.0 for VS 2010

« on: September 28, 2011, 06:14:42 pm »

Hi,
last time I tried installing SFML 2 I already gave up at CMake so I am proud that I got this far  :lol:
I "cmake"d it and used the MSVS-Solution file. Now I have a lib/MinSizeRel folder which includes 15 files.
I also compiled the examples and now wanted to try one so I copied libsnd and the 5 SFML-DLLs to it. Problem is, that it gives me a 0xc000007b error when I try to start the exe.

General / SFML does not show windows on x64

« on: February 06, 2011, 12:51:09 am »

Hi,
I started using Windows 7 64 bit some weeks ago and since then SFML projects won't work. Not only my own projects but also those which I downloaded.
The console windows shows up but after that nothing happens anymore.

Graphics / Image Destructor -> Crash

« on: January 13, 2011, 10:26:15 pm »

Hi,
I'm using Code::Blocks. You know, you can choose between "Debug" and "Release" when compiling a project and if you choose the first, there will be a console window for debugging purposes.
When I close my project the normal way (with exit or ending the main() method) everything works fine.
But when I close the debugging console of Code::Blocks, Windows gives me an error. The Debugger says the following:
#0 5F0D530E   glDeleteTextures() (C:\WINDOWS\system32\opengl32.dll:??)
#1 6871CF5C   sf::Image::~Image() (C:\WINDOWS\system32\sfml-graphics.dll:??)
#2 00404357   __tcf_2() (D:\Programme\CodeBlocks\Projects\Shooter\spriteset.cpp:6)
#3 77C09E24   msvcrt!_initterm() (C:\WINDOWS\system32\msvcrt.dll:??)
#4 77C09EC5   msvcrt!_cexit() (C:\WINDOWS\system32\msvcrt.dll:??)
#5 00000000   0x00000000 in ??() (??:??)

Graphics / PostFX for

Hi,
I'm using SFML 1.6.
Is there a way to use a "for" loop inside the shader file?

Feature requests / 1.6 Shaders

« on: August 23, 2010, 04:19:18 pm »

Hi,
this probably has been requested before but I didn't found something while flipping through this subforum.

In SFML 1.6 you can use App.Draw(Shader) also corresponding to a single Sprite/Shape/String. But as I read once in another topic, in 2.0 you can only use App.Draw(Drawable, Shader). So applying a Shader to the full screen or two or more shaders at once would be a big problem. You would have to create a new image each time which would cause in lag.

So my request (well, more a question) is: Is it possible to bring this feature back?

Graphics / Sprite is drawn as a rect

« on: August 12, 2010, 01:56:12 pm »

Hi,
I have a problem with SFML 1.6.
I have this image:


Which is loaded and used with a Sprite. But for some reason, the image is not displayed as it is but as a white rect:

My class:

Code: [Select]

#include "state_main_menu.hpp"

State_Main_Menu::Button::Button() {}

State_Main_Menu::Button::Button(int cx, int cy, std::string filename) :
    center_x(cx),
    center_y(cy),
    image_filename(filename)
{
    image.LoadFromFile(image_filename);
    sprite.SetImage(image);
}

State_Main_Menu::Button::~Button() {}

std::string State_Main_Menu::Button::get_image_filename()
{
    return image_filename;
}

void State_Main_Menu::Button::set_image_filename(std::string new_filename)
{
    image_filename = new_filename;
    image.LoadFromFile(image_filename);
}

bool State_Main_Menu::Button::is_mouse_over_button(int x, int y)
{
    sf::Vector2f pos(sprite.GetPosition());
    sf::Color color(sprite.GetPixel(x-pos.x, y-pos.y));
    return (color.a > 0);
}

int State_Main_Menu::Button::get_x()
{
    return (center_x - image.GetWidth() / 2);
}

int State_Main_Menu::Button::get_y()
{
    return (center_y - image.GetHeight() / 2);
}

void State_Main_Menu::Button::draw_update(sf::RenderWindow* window)
{
    sprite.SetX(get_x());
    sprite.SetY(get_y());
    window->Draw(sprite);
}

Graphics / PostFX does not work

« on: July 07, 2010, 05:30:28 pm »

Hi,
I've got a problem when using the GLSL feature.
I have created a test project which shows a random number of red semi-transparent circles and on top of that a Sprite.
http://img580.imageshack.us/img580/8747/screenbw.png

But now I tried to create and use a shader (grayscale) but it doesn't work.
My code: http://wurstinator.pastebin.com/zKk6xaNa (I know it's messy but it is just a test project
My shader: http://wurstinator.pastebin.com/b3pWADCd

When I apply the shader the circles are still a bit red:

Hope someone can help =(

/edit: I'm using version 1.6

/edit 2: Solved it, seems like the alpha value has to be 1.
