Zdar,
mam dajme tomu taky obrazok ako v prilohe a chcem aby sa cez tie silno sive pixely nedalo pohybovat s obdlznikom. Cize nejako

if(podmienka){

  ball.speedx = 0- ball.speedx;

  ball.speedy = 0- ball.speedy;

int getpixelred(SDL_Surface* surface, int x, int y)

{

  Uint32 *pixels = (Uint32 *)surface->pixels;

  Uint8 r, g, b;

  SDL_PixelFormat *fmt;

  fmt=surface->format;

  int lineoffset = y* (screen->pitch/ 4);

  SDL_GetRGB(pixels[lineoffset+ x], fmt, &r, &g, &b);

  return r;

}

...

if(getpixelred(s_bckground, ball.x-1, ball.y-1)== 59)...
