Hi, I’m writing a game that is spread out across header files and
implementation files. Currently it has a menu screen (handled by one header-
implementation pair) and a gameplay mode (handled by another). SDL setup
functions, keyboard event handling functions and the functions to display
things on screen (SDL_BlitSurface, SDL_FillRect, etc.) are located in a base
class, which the menu and gameplay classes inherit from. For some reason, the
SDL initialization and SDL keyboard handling functions work properly, but the
display functions do not. Just a black screen comes up, and nothing draws at
any point during runtime. Absolutely no compiler errors are found, everything
runs, no unexpected shutdowns. In my menu, “Exit” is the last option, and if i
hit the down arrow a bunch of times then press enter, the program does exit, so
other SDL features are working (SDL_GetKeystate and events). It’s just for some
strange reason nothing but this black screen opens. Has anybody ever heard of
anything like this? If anyone’s interested in attempting, i can post my code
too; i realize it’s hard to troubleshoot without the code but i don’t want to
unnecessarily spam up your space either. Any help is greatly appreciated.
SDL_Flip(screen_surface_here);
I also posted on Gamedev for you - I just don’t know which one you’ll get
first

No worries, I’ve made the mistake more then once.
