(also in cone3d''s talkbox) Ack! Can someone tell me how to blit bitmaps and stuff with my own coordinates in SDL, cus this''s driving me nuts.

Hi! (I''ve got my own gdnet forum now, so you can ask questons there )

Anyway what do you mean "with your own coordinates?"

I''m working on the second tut right now. Maybe this piece of code will help you:

  // <i>screen</i> must be a global global variablevoid DrawIMG(SDL_Surface *img, int x, int y, int w, int h, int x2, int y2){  SDL_Rect dest;  dest.x = x;  dest.y = y;  SDL_Rect dest2;  dest2.x = x2;  dest2.y = y2;  dest2.w = w;  dest2.h = h;  SDL_BlitSurface(img, &dest2, screen, &dest);}void DrawIMG(SDL_Surface *img, int x, int y){  SDL_Rect dest;  dest.x = x;  dest.y = y;  SDL_BlitSurface(img, NULL, screen, &dest);}// in main() or somewhere ...SDL_Surface *image;// Load a bitmap into imageimage = SDL_LoadBMP("image.bmp");// Now to draw the image onto the screen, useDrawIMG(image, x, y);// where x and y are screen coordinates.// You can also use a more advanced function:DrawIMG(image, x, y, w, h, x2, y2);  

where x and y are the screen coords, w and h are the
width and height of the image to draw. If the w and h
are less than the image size, then the image is cropped
if they are more, then the image is not repeated.
x2 and y2 are the x and y of the image to display at
the point x and y. For example:

  DrawIMG(image, 50, 60, 100, 100, 25, 55);  

With this statement we would blit the SDL_Surface *image onto the screen starting at the point 50x60. We would blit 100 pixels right and down. We would start the blitting (at point 50x60) with the pixel of the image at the point (25x55). On point ((50+100)x60) we would then blit the point ((25+100)x55) from the image.

Hope this makes sence or cleared something up for you. If not, wait for the tut.
