Ich wollte mich mal wieder mit C++ beschäftigen und habe leider keine Ahnung wie ich SFML in C++ (Visual Studio 2013) benutze...
Test Code:
PHP Code:

// ctime for getting system time and
// cmath for sin and cos functions

#include <SFML/Graphics.hpp>
#include <SFML/Audio.hpp>

Als SFML Tutorial habe ich mir ->
Wenn ich versuche alles so einzubinden wie er kriege ich nur Fehler...
