Make it a class hierarchy. It probably needs some thinking to put it
into a single-inheritance hierarchy (multiple inheritance probably is
too ugly in C).

Something like this:

struct Object
{
  int Type;	/* immediate subtypes, i.e. types that start with a "Object" */
  int x,y;
  struct Map *Map;
  ...
};

struct Monster
{
  struct Object Object;
  int Type;	/* immediate subtypes, i.e. types that start with a "Monster" */
  int Race;
  int Str;
  ...
};

struct Player
{
  struct Monster Monster;
  struct PlayerSocket PlayerSocket;
  ...
};

struct Item
{
  struct Object Object;
  int FireProtection;
  ...
};

struct Armor
{
  struct Item Item;
  int AC;
  int Armor;
};

struct Weapon
{
  struct Item Item;
  int Damage;
};

struct EdgedWeapon
{
  struct Weapon Weapon;
  int Sharpness;
};

Things like this. Thatīs just how I would probably do it --- but then, I
this is just a "first idea without any thinking", so please donīt shoot
me if it sucks :-)
