Cały czas robię moją grę i dzisiaj przy kompilacji otrzymałem błąd, i nie mam pojęcia skąd on się bierze.
Log błędu:

sf::Event event;
sf::Font DVS;

sf::Text text;
sf::Texture tex1, tex2;

std::vector < sf::Vector2f > positions( 10 );

const int krok = 10;

#undef VARIABLES_DECLARATIONS_H
#endif // VARIABLES_DECLARATIONS_H

Jeśli zakomentuję lub wyrzucę z projektu plik Player.cpp to normalnie się kompiluje. Ale wystarczy, że odkomentuję tylko dyrektywę

#include

lub jakiś inny fragment kodu i wywala mi ten błąd.

Zmiennych nie definiuje się w nagłówkach.

#undef VARIABLES_DECLARATIONS_H

Wiesz co robisz..?

@Pekfos
Poprawiłem to i dodałem jedną zmienną do klasy Player i działa.
Dzięki :)
