General / Executables not working on other computers (VS2008)

« on: August 05, 2010, 11:10:56 pm »

Hello, this is not SFML related at all, but everytime I compile a program, it won't work on other computers (if they don't have vs2008 I think).

This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix the problem

Do I have to configure something in the project properties? Thanks.

General discussions / SFML for VS2010? When?

I am using it right now, and like it a lot. I would like to know when will you add the build projects to svn.

SFML projects / SFEX - Simple and Fast Extensions

« on: April 25, 2010, 10:36:48 pm »

Description:
This library provides multiple extensions to SFML. At this release you can check the system RAM, get info about the CPU, the GPU and even about the OS.

I hope you don't have any problem with this. It is multiplatform, but I just work with Visual Studio, so I will support only VS projects. There are few files in the source, so it can't be much hard to compile under Linux or Mac anyway.

Installation:
In order to use SFEX, you must have installed:
- SFML2 (https://sourceforge.net/projects/sfml/)
- Hyperic Sigar (http://sourceforge.net/projects/sigar/)
- Glew (http://glew.sourceforge.net/)

Note that Glew and Sigar are actually provided in the folder called "dependencies".

You must link to your projects with:
- opengl32
- glu32
- sigar
- glew
- sfml system
- sfml window
- sfml graphics
- sfex

And maybe you will have to provide Glew and Sigar .dll's. They are also at "dependencies" folder.

Tutorial:
A sample is included in the package. It is very simple to use. Just include SFEX.hpp, call sfex::Init() before any SFEX call, and call sfex::Close() when you are closing your program.

Download:
Release 1
SFEX with dependencies (3.828 KB): Click here
SFEX without dependencies (248 KB): Click here

Next version:
I'm already working in the next version. You won't need to init or close SFEX anymore. Also you won't have to link to SFML graphics (which is so heavy).

General discussions / sf::Ram, sf::Cfg

« on: April 09, 2010, 09:40:12 pm »

I'm writing one or two projects using the namespace sf. One is a couple of functions like:

Code: [Select]

sf::Ram::GetTotalAmount();
sf::Ram::GetFreeAmount();
And the other is a class called sf::Cfg that opens/writes text files using this sintax:

Code: [Select]

Text.txt:
Group name {
    Field 1 = "Text value";
    Group 2 {
        Field 2 = "Value1", "Value2";
    }
}

Should I post'em in the wiki? It isn't multimedia related, so I ask first!

Graphics / Error in RenderImageImplPBuffer.hpp?

« on: April 09, 2010, 07:30:08 pm »

The code is

Code: [Select]

#if defined(SFML_SYSTEM_WINDOWS)

    #include <SFML/Graphics/Win32/RenderImageImplPBuffer.hpp>

#elif defined(SFML_SYSTEM_LINUX) || defined(SFML_SYSTEM_FREEBSD)

    #include <SFML/Graphics/Linux/RenderImageImplPBuffer.hpp>

#elif defined(SFML_SYSTEM_WINDOWS)

    #include <SFML/Graphics/MacOSX/RenderImageImplPBuffer.hpp>

#endif


Notice the MacOSX related line...

#elif defined(SFML_SYSTEM_WINDOWS)

Shouldn't that line be SFML_SYSTEM_MACOS?

Graphics / [FIXED] sf::RenderImage::SetActive()

« on: March 11, 2010, 10:43:51 pm »

Looks like when I am using OpenGL and try to draw to a render image I must draw something (using sf::Sprite) to it, like this:

Code: [Select]

// Activate the window
surface.SetActive(true);
// Explicitely draw a new empty sprite
sf::Sprite sprite;
surface.Draw(sprite);
// OpenGL drawing ...

If I don't, it never activates for rendering. Looks like the problem of explicit binding in images that someone told you a week ago.

Window / RenderImage vs GL

« on: March 03, 2010, 09:38:42 pm »

I am wondering something about render images... this code makes the render image to copy all the pixels from GL to sf::Image? If so, when? Just when I call display?

Code: [Select]

sf::RenderImage image;
image.Create(100, 100);
image.SetActive(true);
glClearColor(0.f, 0.f, 0.f, 0.f);
glClear(GL_COLOR_BUFFER_BIT);
image.Display();
image.GetImage().SaveToFile("lol.png");

General / Using Box2D

« on: March 01, 2010, 09:45:46 pm »

I'm trying to use SFML2 and Box2D together, but when I link my program VS2008 gives this:

1>Vinculando...

Looks like SFML2 and Box2D links to libcmtd or libcmt... what should I do? Thanks.

Feature requests / Sound effects

I searched a little and found nothing about this.
Are you going, Laurent, to make some sound effects? Like reverb or echo.

Graphics / sf::Image::Copy

« on: February 18, 2010, 11:02:16 pm »

I'm having problems copying an image to another.

Code: [Select]

sf::Image texture;
if(!texture.LoadFromFile(fname)) return false;
sf::Image subtexture;
subtexture.Copy(texture, 0, 0, sf::IntRect(x, y, width, height), true);


Console shows that I am trying to access an empty image, but texture was successfull loaded... I am using SFML2, last version, W7.

Any idea why?

General / SFML and Qt

« on: February 07, 2010, 08:23:23 pm »

I am quite newb at Qt. I got it finally working with my IDE(VS2008). Now I would like to know if a could make a sf::RenderWindow (without the use of the QTSFML canvas) and a Qt window apart (something like a console with a Qt GUI). Thanks :-)

Feature requests / sf::Sprite::GetWidth&GetHeight

« on: January 21, 2010, 09:56:11 pm »

If you have a sprite that have assigned an image with (x, y) size, would be nice to have a function that returns the image size per sprite's scale.

Example:

Code: [Select]

Image img
Load img
Sprite spr
Assign img to spr
Scale spr 1/2, 1/2
-> Get spr width
-> Get spr height

Graphics / SFML2 -> No more PreserveOpenGLStates?

« on: November 26, 2009, 01:43:46 am »

I see that this function dissapeared, whats the way it works now?
1 - It is enabled by default? Or disabled by default? I prefer something that doesn't eat CPU :-)
2 - In the SFML2 code sample called OpenGL, you have

Code: [Select]

       // Activate the window before using OpenGL commands.
        // This is useless here because we have only one window which is
        // always the active one, but don't forget it if you use multiple windows
        window.SetActive();

I noticed that the box is only drawn if you activate the window. If you don't, it wont be displayed, so it isn't useless, it's necessary.

Graphics / SFML2: Strange behavior (threading GL)

« on: November 22, 2009, 11:00:03 pm »

I am using Windows XP, SFML2, revision 1279
I have an sf::Image manager, and it loads well. But when I try to use a sf::Sprite, it is not well drawn, but well saved to file!

Code: [Select]

// Load is called once
void Scene::load()
{
marker_sprite.SetImage(*game.resource["data/image/marker.bmp"]);
marker_sprite.GetImage()->SaveToFile("marker.bmp"); // The file is saved ok
}

// Draw is called every frame
void Scene::draw()
{
game.window.Draw(marker_sprite); // Sprite just draws a white square
// If I try to save the image in this scope, the image is saved ok
marker_sprite.GetImage()->SaveToFile("marker2.bmp");
}

// To make sure that my stored image is not deleted, I save the image when I close the window
void Scene::closed()
{
marker_sprite.GetImage()->SaveToFIle("marker3.bmp");
}

All three saved bmp's are OK! I don't understand why it draws a white square.

If I use a sf::Image stored in my Scene class it works.

I think it's not my fault because I can save the images correctly :-S

General discussions / [solved]VS2008, how to change execution working dir?

« on: November 19, 2009, 01:38:06 pm »

I know it's not SFML related, but I searched a lot without any finds.

I would like to change the directory where my debugging .exe will be executed (like CodeBlocks with Execution working dir, in Build targets).

Thanks.

EDIT: Thanks Laurent
