Hello,
I'm on day 10, trying to print the FPS etc to the console.
Casey is using something like this :
This is not working for me. I have no compile errors, but I'm also not seeing anything in the output console ?!?
I'm using VS2015 on Windows 10.
Anyone knows what's going on?
Thanks !

cause it's not pushing things to the console
all it does is put the formatted string in buffer. Which you then need to pass to OutputDebugString

Isn't the wsprintf function for wide chars? If yes, then you are using wsprintf a bit incorrectly.
Wide chars means that your buffer must be with wchar_t type. Also your format string must be wide string, and you must be careful with formatting specifiers (%s is wchar_t string and %S is char). And you need to use OutputDebugStringW function to output it.
So it should look like this:
Notice the wchar_t and L before the string literal.

no for wide chars output it's wsprintfW
wsprintf is an extended sprintf that can deal with wide character arguments with %ls

Oh, right. That's Windows API function. The actual function he's using is wsprintfA.
I was thinking about swprintf function from stdio.h.
