New Tutorial on getting started with SDL
I had this tutorial pencilled in to do and it’s now done. It’s the old SDL rectangles program that was part of the eBook. I’ve modernised it a bit so the same file will now compile under either MSVC on Windows or VS Code/Clang on Linux without changes.
I used the _WIN32 predefined macro so it compiles the call to Windows cod on Windows. Here’s an example:
#ifdef _WIN32 sprintf_s(buff, sizeof(buff), "%10.6f", getElapsedTime(&s)); #else snprintf(buff, sizeof(buff),"%10.6f",diff(&s)); #endif
I do a similar thing with the path to SDL which is “SDL.h” on Windows but “SDL2/SDL.h” on Ubuntu. Writing code this way makes it lot less of a hassle.
