using namespace player;

int main(){
	
	//Logic Phase
	init_inventory();
	init_questlog();
	
	for (int x = 0; x < 25; x++)
	{
	
	cout << x << ":" << quest_log[x].title;
	
	}
	
	//Initial Graphics Phase
		//Open render window
		//Load Graphics
		
	//Game loop
	
	//Render phase
	
return 0;
}

I'm still getting my bearings when it comes to object oriented programming, I'm really learning as I go, but I am getting a message that doesn't make sense to me when I try and compile this code.

quest.cpp:(.bss+0x0): multiple definition of `quest_log'
main.cpp:(.bss+0x0): first defined here
[Error] ld returned 1 exit status

}quest_log[max_quests];

This object is defined in a header file and is then included in multiple files, you can't do this. Also, it's a global variable, and you should not have global variables.

quest_log should be in main and should be its own class, init_questlog and add_questlog should be members of the class.

That makes a lot more sense, and yeah I've heard the global variable thing, but I was also reading that in games it's sometimes necessary. Thank you very much :).
