Hi, i have a little problem. Now i have some Classes like cWorld, cPlayer, cInput, cLog... ! i have put them in the files like cWorld.cpp/h, cPlayer.cpp/h... The Main File is main.cpp. New i implemented all classes in main.cpp like this #include "CWorld.h" #include "CPlayer.h" cWorld world; cPlayer pl; Ok, that

s allright. Now my problem... For Example i want to use in cInput the world deklaration. but how can i implement something. I thought like an globals.h where all the deklaration are and every file can use the world and other files. But i don

t know how. Thanks Lutz Hören P.S. sorry for my bad English, not my native language

look up ''extern'' i think that might have something to do with it, not sure i''m new.

I usually do something like that:

    
///////////////////

// input.h

///////////////////

class CInput {
...
};

extern CInput Input;

///////////////////

// input.cpp

///////////////////

CInput Input;

...

Now you have one global instance of CInput called Input. You can use it anywhere where input.h has been included.
