C++ :: Constructing Text Adventure - World Class To Hold Objects From Character

I am working with a new text adventure. The way i want to construct it is by having a class for all living things. in the class you have basic things as: health, gold, vector for inventory holding "struct item". etc...

There is also a class called world, wich navigates through the world.

World class contains of: player location, and a map containing info about the room etc...

Here comes the problem. I want there to be characters to be placed out in different maps, so basically i want the world class to hold objects from Character.

How to do it. In world class i made a map...

std::map<int,"content">

content is a struct i made above in world class:

struct content{
std::string name; // location name
std::string info; // info about location
std::vector<Character>characters;
std::vector<item>items;
};

To sum it up, i have a std::map<int,content>map the int stands for location id. Content holds more info about the room and what's in it

btw the classes are in different files and that means i have to include "Character.h" in the world file so i can set up the vector of characters.
