Hej!
Pisze pierwsza gre na komorke z Win7.
Uzywam XNA.
Chce zrobic sterowanie moim "robocikiem" za pomoca prostych gestow: user przesuwa palcem w jakims kierunku, ja odczytuje ten kierunek.
Ponizszy kod dziala ale jest malo "responsive" i czasem dziala w odwrotnym od zamierzonego kierunku.
Co robie zle?
Pieknie dziekuje!
