[SDL] Pixel Plotting

Well I don´t remember any specific function on SDL that draws one pixel at a time (like the one on GDI), but maybe the code on this site can enlighten you:

Thanks! That looks like what I'm looking for.

This brings up another question. When using SDL, I see a lot of 'Uint32' and 'Uint16' etc. What is that? I mean, obviously it's some type of integer, but beyond that?

The 'U' means unsigned. The number (16, 32) tells you how many bits are allocated for that variable. So Uint32 is a 32 bit integer.
This is done because the size of int varies between systems, so making their own custom data types increases portability.

SDL_gfx has the following two functions:

int pixelColor(        SDL_Surface * dst,        Sint16 x, Sint16 y,        Uint32 color);int pixelRGBA(        SDL_Surface * dst,        Sint16 x, Sint16 y,        Uint8 r, Uint8 g,        Uint8 b, Uint8 a);

... Fairly self explanitory.

Yes, that'll be easier, since I'm implimenting SDL_gfx anyways. Thanks!
