Sdlx And The Xdk Options

[richi902]

hi,

i'm trying to get one of the sdl samples running on the xbox from

http://lazyfoo.net/SDL_tutorials/lesson01/index2.php

i modified mine to look like this

CODE

#include "SDL.h"
#include "xstring"


//The Surfaces
SDL_Surface* Padel = NULL;
SDL_Surface* Screen = NULL;

//void __cdecl main()

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;

    //Load the image
    loadedimage = SDL_LoadBMP(filename.c_str());


    //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;
}

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);
}

int main(int argc, char* args[])
{
    
    
    //Fireup SDL
    SDL_Init(SDL_INIT_EVERYTHING);
    //Setup SDL Screen
    Screen = SDL_SetVideoMode( 640, 480, 16, SDL_SWSURFACE | SDL_ANYFORMAT);
        
    //Window Name
    SDL_WM_SetCaption( "SDL Test APP", NULL );

    //Loading Bitmap
    Padel = load_image("image/sprite_one.bmp");
        
    //Apply image on screen
    apply_surface(180, 140, Padel, Screen);
    apply_surface(240, 80, Padel, Screen);

    //update the screen
    SDL_UpdateRect(Screen, 0, 0, 0, 0);

    //Pause
    SDL_Delay(15000);
    
    //Free the loaded image
    SDL_FreeSurface(Padel);
    
    //Quit SDL
    SDL_Quit();

    return 1;
    
}

it compiles fine but it displays no picture on the screen, just a black screen.
the bmp is in the main folder of the xbe on the xbox "e:/games/xbox_sdl/sprite_one.bmp"

i can confirm that the xbe itself is working, because if i change the amount of time for the
SDL_Delay it takes that amount of time to go back to the dash.

so my questen is, whats wrong?

i think 1 have sdlx correctly installed(Microsoft Xbox SDK\xbox\includes and \lib).

is there anything i need to keep in mind while porting windows stuff to the xbox?

oh and i have the latest xdk(59) and the sdlx from hyper_eve's svn
(compiled that in "trunk", i'm not really used to that svn stuff)


hope someone has a clue to fix my problem, thanks in advance


edit:
i forgot to add that it compiles and runs under windows fine and display the bmp

He is aware of that. He just wants to skip that step because it holds up the build process. If you don't have a machine to deploy to that step takes a little bit before it fails. The instructions I provided allow you to disable deployment and avoid the issue. It makes building without a deployment target much faster.

i installed a debug bios now anyway, i used that x2 bios so i can still keep my other dashboard.
it is much better to just press the button and it copys the new file over .
now i just need to learn more c(++) :/ gets too confusing sometimes, and i have a hard time understanding,
especially classes, functions and arrays(and probably some other stuff), well just the hole c++ lol.
