Re: game development question:reading and writing game data to and from files

yeah, I know it doesn't have to be the same, but I need a way of storing the type or I need to store the type rather in what ever format I choose.

You don't' have to do string to string.

Do string to some object .... Do some object to string ... It doesn't
matter.

Take care,

Sina:
What I was going to do was something like:
class player
{
private:
map <string,string> *values;
};
then I could write a save function on top of that.
I could always do something like:...
#define TYPE_INT 1
#define TYPE_STR 2
struct variant
{
union
{
int i;
string str;
} v;
int type;
};
but I'd have to store the type of the variant... somewhere

Struct TyStruct {
ObjectTypeTheFirst first;
ObjectTypeTheSecond second;
int id;
char* name;
}

Then just make a map of hashes or ints or whatever, each to an object of
type TyStruct.

Instead of struct, make it a class with full type safety and so on.

Sina

hmm, so I would store the pointer to an int/string/double.
I need to be able to tell what it is though, no?

The map definitely handles this bro.

Just don't make it a map of primative to primative, make it a map of
primative to object.  That object can be of any type you like.

Take care,
Sina

Hello all,
I've started work on a custom mud, and am trying to figure something out. 
Each player will have a set of keys that will be stored, name, connect
time,
creation time, etc.
I was thinking of storing these in a map, but that requires that the map
hold multiple values; something which the c++ map doesn't do.
So, I'm trying to figure something out.
I'd like to be able to store player data, and a list of the player's
inventory so the objects can be recreated when the player connects
somehow.
I would need to store object type, name, etc etc.
I'm not quite sure how I could achieve this easily; I could possibly
itterate through the map once I've gotten the data type thing figured out 
and do something like write key=value.
Then when I loaded it I could just strtok on the = and set that up, but
I'm
not quite sure how I'd handle inventory and that.
This is the only snag I'm having so far, and I'm not able to move on
without
it, as I'm to the point where I need to start saving player data, so help 
would be really appriciated at this point. :)
Thanks,
