...or shitrndr for short, is a boilerplate header for single-window SDL2 applications.
It provides an SDL_Window* and SDL_Renderer* created using the provided parameters, as well as a render loop, input manager and event handling. It also provides a simple way to handle rendering at a set resolution in a re-scalable window, in the form of a pixScale and lockTypes.
As mentioned before, shitrndr is a header. That's it.
To use it in your project, simply include it and make sure the right compiler flags are on.
See the demo files for a simple usage demonstration.
If you're using clang++/g++, you're going to need these:
--std=c++17-- for inline functions and variables, that are there in case you're insane enough to use this in a project consisting of more than a single file-lSDL2-- I'm guessing you already have this one, considering you're looking at obscure SDL2 program aids
...and that's it if you're compiling natively on Linux with clang++/g++. If you're using something else, however, here are the additional flags you might need to add:
Aside from the flags mentioned above, you'll need to add the flags listed below if you don't want to ship your executable with a bunch of DLLs:
-static-libgcc -static-libstdc++ -Wl,-Bstatic -lstdc++-- with MINGW, you have to specify these standard libraries for it to link them statically.
Emscripten won't need any of the above to compile, but to include & link the SDL2 port to your application, add:
-s USE_SDL=2
Hopefully that was helpful, if not, I can't really say I'm surprised.
