C / Strange errors

« on: July 28, 2010, 08:46:18 pm »

I´m getting these 2 errors that are strange, because everything is written OK.

main.c

Code: [Select]

#include <SFML/Graphics.h>

int main()
{
sfRenderWindow_Create(sfVideoMode(800,600,32), "SFML", sfResize | sfClose, sfWindowSettings());
return EXIT_SUCCESS;
}

errors

Code: [Select]

1>.\main.c(6) : error C2143: syntax error : missing ')' before 'type'
1>.\main.c(6) : error C2198: 'sfRenderWindow_Create' : too few arguments for call

Don´t know if it is because of CSFML or some project options need to be set (using VC2005, compiling as "C" code(but it also happens if compiled as "C++" code))

C / VS2005 linking error: unresolved external symbol

« on: July 25, 2010, 04:38:29 pm »

I´ve just started with CSFML and i am getting linking errors everytime i try to compile my app (i am using Visual Sudio 2005, as i´ve said in title).
I´ve included all needed libraries for app (csfml-audio.lib, csfml-graphics.lib, csfml-network.lib, csfml-system.lib, csfml-window.lib). Here is the code:

SoundSystem.h

Code: [Select]

#include <SFML/Audio.h>
#include "DataTypes.h"

// sound
extern void PlayMusic(C8 *FileName);

SoundSystem.cpp

Code: [Select]

#include "DataTypes.h"
#include "SoundSystem.h"

sfMusic *Music;

void PlayMusic(C8 *FileName)
{
sfMusic_CreateFromFile(FileName);
sfMusic_Play(Music);
// Loop while the music is playing
while(sfMusic_GetStatus(Music) == sfPlaying)
{
sfSleep(0.1f);
}
}

main.cpp

Code: [Select]

#include "SoundSystem.h"

int main()
{
PlayMusic("data/sound.ogg");
return EXIT_SUCCESS;
}

...and here are the linking errors.

Code: [Select]

1>Compiling...
1>main.cpp
1>SoundSystem.cpp
1>Linking...
1>SoundSystem.obj : error LNK2001: unresolved external symbol "void __cdecl sfMusic_Play(struct sfMusic *)" (?sfMusic_Play@@YAXPAUsfMusic@@@Z)

1>SoundSystem.obj : error LNK2001: unresolved external symbol "struct sfMusic * __cdecl sfMusic_CreateFromFile(char const *)" (?sfMusic_CreateFromFile@@YAPAUsfMusic@@PBD@Z)

1>..\bin32\game_c.exe : fatal error LNK1120: 4 unresolved externals

I don´t know if i´ve forgot to set some options to compiler or forgot to include some file... so i´m looking for a help.

Window / Combined event types

« on: March 12, 2010, 05:51:33 pm »

I am new to SFML, so I still learn new stuff about library everyday but I am interested is it possible to combine event types? For example, i want to create rotational camera with OpenGL which user rotates when he press right mouse button and moves mouse. Ive tried something like this:

Code: [Select]

if ((Event.Type == sf::Event::MouseButtonPressed || sf::Event::MouseMoved) && (sf::Mouse::Right))


but it doesn´t do nothing.
If needed, I would post whole source code of application.
