Hey Guys,
So I am working on a program in class that asks for the age of your dog and translates it into human years....needless to say overly easy and boring.
So I want to get into adding sprites to C. My first question is where I can find some good info on adding sprites and animation as I have never done it before and my next question is what do I need to add this code to my C compiler (Dev-C++ is what im running)

#include "SDL.h"

#define SCREEN_WIDTH  640
#define SCREEN_HEIGHT 480
#define SPRITE_SIZE    32

int main ( int argc, char *argv[] )
{
  SDL_Surface *screen, *temp, *sprite, *grass;
  SDL_Rect rcSprite, rcGrass;
  SDL_Event event;
  Uint8 *keystate;

  int colorkey, gameover;

  /* initialize SDL */
  SDL_Init(SDL_INIT_VIDEO);

  /* set the title bar */
  SDL_WM_SetCaption("SDL Move", "SDL Move");

  /* create window */
  screen = SDL_SetVideoMode(SCREEN_WIDTH, SCREEN_HEIGHT, 0, 0);

  /* load sprite */
  temp   = SDL_LoadBMP("sprite.bmp");
  sprite = SDL_DisplayFormat(temp);
  SDL_FreeSurface(temp);

  /* setup sprite colorkey and turn on RLE */
  colorkey = SDL_MapRGB(screen->format, 255, 0, 255);
  SDL_SetColorKey(sprite, SDL_SRCCOLORKEY | SDL_RLEACCEL, colorkey);

  /* load grass */
  temp  = SDL_LoadBMP("grass.bmp");
  grass = SDL_DisplayFormat(temp);
  SDL_FreeSurface(temp);

  /* set sprite position */
  rcSprite.x = 0;
  rcSprite.y = 0;

  gameover = 0;

  /* message pump */
  while (!gameover)
  {
    /* look for an event */
    if (SDL_PollEvent(&event)) {
      /* an event was found */
      switch (event.type) {
        /* close button clicked */
        case SDL_QUIT:
          gameover = 1;
          break;

        /* handle the keyboard */
        case SDL_KEYDOWN:
          switch (event.key.keysym.sym) {
            case SDLK_ESCAPE:
            case SDLK_q:
              gameover = 1;
              break;
          }
          break;
      }
    }

    /* handle sprite movement */
    keystate = SDL_GetKeyState(NULL);
    if (keystate[SDLK_LEFT] ) {
      rcSprite.x -= 2;
    }
    if (keystate[SDLK_RIGHT] ) {
      rcSprite.x += 2;
    }
    if (keystate[SDLK_UP] ) {
      rcSprite.y -= 2;
    }
    if (keystate[SDLK_DOWN] ) {
      rcSprite.y += 2;
    }
    /* collide with edges of screen */
    if ( rcSprite.x < 0 ) {
      rcSprite.x = 0;
    }
    else if ( rcSprite.x > SCREEN_WIDTH-SPRITE_SIZE ) {
      rcSprite.x = SCREEN_WIDTH-SPRITE_SIZE;
    }
    if ( rcSprite.y < 0 ) {
      rcSprite.y = 0;
    }
    else if ( rcSprite.y > SCREEN_HEIGHT-SPRITE_SIZE ) {
      rcSprite.y = SCREEN_HEIGHT-SPRITE_SIZE;
    }

    /* draw the grass */
    for (int x = 0; x < SCREEN_WIDTH / SPRITE_SIZE; x++) {
      for (int y = 0; y < SCREEN_HEIGHT / SPRITE_SIZE; y++) {
        rcGrass.x = x * SPRITE_SIZE;
        rcGrass.y = y * SPRITE_SIZE;
        SDL_BlitSurface(grass, NULL, screen, &rcGrass);
      }
    }
    /* draw the sprite */
    SDL_BlitSurface(sprite, NULL, screen, &rcSprite);

    /* update the screen */
    SDL_UpdateRect(screen, 0, 0, 0, 0);
  }

  /* clean up */
  SDL_FreeSurface(sprite);
  SDL_FreeSurface(grass);
  SDL_Quit();

  return 0;
}

You need to write GUI programs if you want to add sprites. The easiest way to do it is probably with OpenGL or DirectX libraries.

>>Dev-C++ is what im running)
Ditch it and install Code::Blocks with MinGW. Its a better IDE and supports current versions of g++ while Dev-C++ is neither.

THANKS! What exactly is GUI?
I am on my school computer right now but will download MinGW when i get home. also g++ ? sorry I am a beginner programmer.

g++
GUI
Searching for the terms in any search engine will help you to avoid to explain that you are a beginner programmer.

If you download Code::Blocks binaries it will contain MinGW. If you are beginner programmer then you probably don't have enough c++ background to code a GUI program yet. Learn the basics of the language first, then in several months you MIGHT know enough to write your sprite program.

Eff it. i'm gonna learn to fly. i'll figure out how to walk, later.
