I've got a set of SDL2 test programs here : https://onedrive.live.com/redir?resid=DD5B5E7788984419!6233&authkey=!ACvDUUgC1vgaDZU&ithint=file%2crar

With the exception of the starfield and sprite speed tester (of which the latter will show the SDL_CreateWindow problem), most of these examples are simple test programs for my Triority system - essentially, its a program processing system based on GLBasic. I did this in case the author of GLBasic decided to stop updates (which have been slowing down for a while anyway), and thus would allow me to convert code fairly simply.

But I digress...

Some piccies : https://onedrive.live.com/redir?resid=DD5B5E7788984419!6234&authkey=!AGhAA-GmihPxM4o&v=3&ithint=photo%2cpng and https://onedrive.live.com/redir?resid=DD5B5E7788984419!6235&authkey=!AG218rqhJX-BpaE&v=3&ithint=photo%2cpng

The starfield code is :

Code:
#include "Triority.h"

int main(int argc, char * argv[])
{
   DGArray<DGInt> stars;
   DGNat scx, scy;
   const char *organisation = "Triority";
   const char *programName = "Starfield";

   if (__GLB_Defaults(argc, argv, organisation, programName) == false)
   {
      END();
   }

   GETSCREENSIZE(scx, scy);
   SYSTEMPOINTER(false);

   LOADSOUND("3.ogg", 0);
   LOADSOUND("2.ogg", 1);
   LOADSOUND("1.ogg", 2);
   LOADSOUND("go.ogg", 3);

   for (int i = 0; i<4; i++)
   {
      PLAYSOUND(i, 0.0, 100.0);
      while (SOUNDPLAYING(i))
      {
         SHOWSCREEN();
      }
   }

   PLAYMUSIC("romancandle_30.ogg", false);

   DIM(stars, 1001, 6);
   for (int i = 0; i<1001; i++)
   {
      stars(i, 0) = RND(4000) - 2000;
      stars(i, 1) = RND(4000) - 2000;
      stars(i, 2) = RND(4000) + 1000;
      stars(i, 5) = (25 + RND(100));
   }

   while (true)
   {      
      for (int i = 0; i<1001; i++)
      {
         stars(i, 2) = stars(i, 2) - stars(i, 5); // speed
         if (stars(i, 2) <= 0)
         {
            stars(i, 0) = RND(4000) - 2000;
            stars(i, 1) = RND(4000) - 2000;
            stars(i, 2) = RND(4000) + 1000;
            stars(i, 5) = (25 + RND(50))*GETTIMER() / 25;
         }
         stars(i, 3) = (stars(i, 0) * 100) / stars(i, 2);
         stars(i, 4) = (stars(i, 1) * 100) / stars(i, 2);
         SETPIXEL(scx / 2 + stars(i, 3), scy / 2 + stars(i, 4), GLRGB(255, 255, 255));
      }

      ALPHAMODE(1.0);
      PRINT("FPS : " + FORMAT_Str(4, 4, GETFPS()), 0, 0, false);
      PRINT("Is full screen : " + FORMAT_Str(2, 0, ISFULLSCREEN()), 0, 16, false);
      PRINT("Resolution : " + FORMAT_Str(4, 0, scx) + " x " + FORMAT_Str(4, 0, scy), 0, 32, false);
      PRINT("Press ALT+RETURN to switch between full screen and  window mode", 0, 48, false);
      PRINT("Time : " + PLATFORMINFO_Str("TIME"), 0, 64, false);
      PRINT("Battery : " + PLATFORMINFO_Str("BATTERY"), 0, 84, false);

      SHOWSCREEN();
   }

   return 0;
}
