Graphics / Passing an SFML handle to a function

« on: May 07, 2013, 10:25:00 pm »

SFML forum,
  SFML 1.6  Visual C++ 2010

 I have some working SFML programs and need to find out how
 to pass a handle to a function.

int main()
{
        sf::RenderWindow Screen(sf::VideoMode(640, 480, 16), "SFML Window");
-
???? function(Screen);
-
        return EXIT_SUCCESS;
} // end of main


???? function(sf::???)
{
        -
        want to do some "Screen" commands in this function
        -
        -
return ???
} // end function(sf:???)
 

 How do I do this?

Audio / sfml-audio-d.lib causes openal32.dll error

« on: May 05, 2013, 07:34:48 am »

SFML forum,
 SFML1.6   Visual C++ 2010

 I'm putting sounds in a working program for the first time.

 My code compiles OK if I put sfml-audio-d.dll in
 Linker > Input > Additional Dependencies.

 But then when I run it I get the error:
 This application has failed to start because openal32.dll was not found.

 I have tried #include <path to the openal.dll file>
 but then I get a whole screen full of errors when compiling.
 I also get a Microsoft Package Server error window saying
 "Micorsoft(R) Visual C++ Package Server has encounted a problem
 and needs to close".

 I have other programs running OK but without any sound code.

 I have read a few web sites about openal32.dll but couldn't
 find a solution for this.

 Any Suggestions?

Graphics / SubRect Problem

« on: May 05, 2013, 03:18:20 am »

SFML forum,
 SFML 1.6  Visual C++ 2010

 I have an png that is 64 x 320 and contains 5 sprite pictures.
 1 2 3 4    the last one is blank.

 If I use:
 Numbers.SetSubRect(sf::IntRect(0,0,63,63));
 Screen.Draw(Numbers);
 a 1 is dispayed.

 If I use:
 Numbers.SetSubRect(sf::IntRect(64,64,127,127));
 Screen.Draw(Numbers);
 nothing is dispayed.

 If I use:
 Numbers.SetSubRect(sf::IntRect(0,0,127,127));
 Screen.Draw(Numbers);
 1 2 is dispayed.

 etc.......

 I have successfully used the same png file in another IDE
 where all I have to do is set the frame number.

 I have attached the .png file.

 Any suggestions?

Graphics / setOrigin fails

« on: May 03, 2013, 04:30:30 am »

SFML forum,

 SFML 1.6,  Visual C++ 2010

 I load an image and set it as a sprite:

   MyImage.LoadFromFile("Sprite2.bmp"))

   // Create a sprite called Rocket from MyImage
   sf::Sprite Rocket(MyImage);

 This all works and the sprite appears on the screen.

 Now when I try to set the origin of the sprite:
   Rocket.setOrigin(25, 25);

 I get a compiler error saying:
 error C2039: 'setOrigin' : is not a member of 'sf::Sprite'

 What am I doing wrong here?

Graphics / Sprite.setOffest causes compiler error

« on: April 23, 2013, 05:13:42 am »

SFML forum,

 SFML 1.6,  Visual C++ Express 2010

 I've searched this forum for posts on this subject but
 none of them answer my question.

 I want to relocate the x/y origin of a sprite for rotation.

 I've seen example programs that uses code like:
 Sprite.setOrigin(100, 100);

 But if I try to use this I get a compiler error that says:
 error C2039: 'setOrigin' : is not a member of 'sf::Sprite'

 This command exists in the sf::Sprite Class Reference so
 I'm confused and stuck?

Graphics / LoadFromFile always fails

« on: April 20, 2013, 07:28:37 am »

SFML forum,

 SFML 1.6  Visual C++ Express 2010

 I'm new to SFML and have a very simple "open a window" program
 called FirstWindow that works.

 Now I try to load an image with this code:
   sf::Image MyImage;
   MyImage.LoadFromFile("Sprite2.bmp");

 It compiles without errors but when I run it I get this message:
 "FirstWindow has encountered an error and must close".

 If I comment out the LoadFromFile command the program runs OK.

 The file Sprite2.bmp resides in the program folder and I
 can open it and see the bmp image.

 Any suggestions?
