Posted 12 October 2012 - 10:12 PM

Hello again,

im having more troubles with SDL. I am following lazy foo's toutorials and i did the second project.

CODE:
#include "SDL.h"
#include <string>
using namespace std;
//attributes of the screen
const int SCREEN_WIDTH = 640;
const int SCREEN_HEIGHT = 480;
const int SCREEN_BPP = 32; //bits-per-pixel
//Surfaces
SDL_Surface *message = NULL;
SDL_Surface *background = NULL;
SDL_Surface *screen = NULL;
void apply_surface( int x, int y, SDL_Surface* source, SDL_Surface* destination ) {
//Make a temporary rectangle to hold the offsets
SDL_Rect offset;
//Give the offsets to the rectangle
offset.x = x;
offset.y = y;
//Blit the surface
SDL_BlitSurface( source, NULL, destination, &offset );
}
SDL_Surface *load_image( std::string filename ) {

//Temporary storage for the image that's loaded
SDL_Surface* loadedImage = NULL;
//The optimized image that will be used
SDL_Surface* optimizedImage = NULL;
  //If nothing went wrong in loading the image
if( loadedImage != NULL ) {
  //Create an optimized image
  optimizedImage = SDL_DisplayFormat( loadedImage );
  //Free the old image
  SDL_FreeSurface( loadedImage );
}
  //Return the optimized image
return optimizedImage;
}
int main( int argc, char* args[] ) {
//Initilize
if(SDL_Init( SDL_INIT_EVERYTHING ) == -1) return 1;
//Set up screen
screen = SDL_SetVideoMode( SCREEN_WIDTH, SCREEN_HEIGHT, SCREEN_BPP, SDL_SWSURFACE );
if( screen == NULL ) return 1;

//set video caption
SDL_WM_SetCaption( "Hello World", NULL );

//Load image
message = load_image( "hello.bmp" );
background = load_image( "background.bmp" );
//Apply image to screen
apply_surface( 0, 0, background, screen );
apply_surface( 320, 0, background, screen );
apply_surface( 0, 240, background, screen );
apply_surface( 320, 240, background, screen );

//Apply the message to the screen
apply_surface( 180, 140, message, screen );


//Update Screen
if( SDL_Flip( screen ) == -1 ) return 1;

//Pause
SDL_Delay( 10000 );
//Free the loaded image
SDL_FreeSurface( message );
SDL_FreeSurface(background);

//Quit SDL
SDL_Quit();
return 0;
}
(Sorry i dont know how to put the code in those things)

and i get this message when im done:

The program '[2768] Space Game.exe: Native' has exited with code 0 (0x0).

so the program runs for the 10 sec, but its black. There is no picture. I have all the files and librarys/linker stuff done right. My image Background is 320 by 240. and the hello is 280 by 200. im not sure if i did the math right, or if there is some other problem but i need some help.

: Added code tags for you.
