sending a class address to a new function..

[levone]

first, hello all. err... was gonna say more on the lines of hello but i forgot... that quick... sad...

moving on.

so here's my problem.

Attack( &Main, &enemy );&&

int Attack( Character * attacker, Character * defender )
{
    std::cout << std::endl;
    std::cout << "attacker strength: " << attacker->GetStr() << std::endl;
    std::cout << "defender defence: " << defender->GetDef() << std::endl;
    return 0;
}

produces...

im using visual studios, and the problem is that in main, i call Attack() and pass on the address of 2 classes.

however, it wont compile, linker errors... the ones that are confusing...

i think that whats happening is that the attack function, or this part of it anyway...
"int Attack( Character * attacker, Character * defender )"
attempts to create already existing class object or something...

so is there a way to pass an address of a class on to a function without getting an error? i really don't feel like gathering the data from the classes and passing that on for my method to work with... to un-organized.

here is the full source if anymore info is needed.

thanks in advance..
i really didn't expect this error. :s


EDIT:

is there a way to subscribe to topics on this forum... not seeing a button. (still looking)

Have two source files, main.cpp and BattleSystem.cpp, that have compiled copies of two constructors for class Character.

Do you have the source code for these constructors in a header file that is not inline?

i supplied the full source to the project here (its very incomplete as i just started working on it....)

http://www.mediafire.com/?knfynznwa0m

i have the entire class, and all its methods(functions), in Character.h header file.
included in both main.cpp and BattleSystem.cpp

EDIT:

wtf...

ok well i fixed it, i moved the constructor method into main.cpp and now it links.

thats odd... but w/e
really suck tho cause i would like to be able to group related stuff like that into one single file.

^^That's your problem right there
