  • Wie ktoś jak sie wczytuje pliki w C++? Albo moze ktoś podać mi żródła gdzie to znalesc w jakich ksiazkach lub gdzie w necie?
    Z gory dzieki!

  • Jeśli to C++, to musi działać, inaczej robisz coś bardzo głupiego. Już lepiej pochwal się kawałkiem kodu.

    A Grey czytać nie umie, bo Rataj się zajmuje Javą u nas na wydziale. ;)

    Prawda moj blad :D Ale Rataj kiedys prowadzil C++ wiec moze daloby rade znalesc co nie zmienia faktu ze nie chodzilo mi o 'te' wyklady ; )

  • Wszyscy czytają "twój" kod i myślę, że całkiem za darmo na jutro będziesz miał tutaj 5 gotowych rozwiązań.
    Jak ty nie potrafisz użyć choćby nopaste, to i przy zadaniu, w którym sam nie wiesz co masz zrobić nikt ci nie pomoże raczej,

  • Człowieku! Czy ty słyszałeś kiedyś o serwisach w rodzaju wklej.org? Odechciewa się pomagać ludziom, którzy potrafią wstawić kilka ekranów kodu żywcem w poście. Do tego trzeba było pokazać tylko te fragmenty kodu, w których tkwi problem, a nie cały kod.

  • Heh kolega Miluszek chcialby pomocy lecz nie wie w czym O_O

    Stary idea wczytywania czegos z pliku jest latwa wiec nie trzeba tego tlumaczyc osobno do wszystkich rzeczy ktore mozna z niego wczytac najpierw zacznij od poczytania co to sa mapy etc. bo wnioskuje ze nie wiesz a pozniej zastanow sie jak to wczytac korzystajac z linkow podanych przez kolegow.
