Hi there. Well, honestly this is very easy. One salution that I might recommend is one that I use and is easy, also one that works with most games. It's the dictionary object. All you do, is declair the dictionary.
dictionary save;
Then add values, with what ever keys you want, I do it like this, here is a complete function to save settings:
void save_settings()
{
dictionary d;
d.set("1", location);
d.set("2", city);
// just continue adding with 3 as the key, and the variable as the value, continue encreasing the number every value/variable you want to add
string text_to_write=serialize(d);
// now, encryption! Do this unles you want other bgt geeks to be able to change your data!
text_to_write=string_encrypt(text_to_write, "no_touching_my_data");
// now let's save our data
file f;
f.open("save.dat", "wb");
f.write(text_to_write);
f.close();
} // end save function
So basicly in that function we saved all the values to a dictionary. the function wants: get(string key, ? value) and the ? value, means value can accept any type of variable.
and now, let's say we need to load that data we saved
void load_data()
{
// retrieve the data
file f;
f.open("save.dat", "rb");
string text_to_read=f.read();
f.close();
// now for decryption
text_to_read=string_decrypt(text_to_read, "no_touching_my_data");
// now to get the data back into a dictionary
dictionary d=deserialize(text_to_read);
// now, load the data
if(d.exists("1"))
d.get("1", location);
if(d.exists("2"))
d.get("2", city);
// and on and on for every new value that is saved, and there you go
}
Note that checking weather a value exists before actually restoring it is necessary or else you could end up having blank strings and zeroed integers, which might be different from default values. The get function wants: get(string key, &out ? value)
&out means it writes the data to a variable rather than returning anything, so if you have location, if said value was saved in the dictionary it would just write to the location variable. I hope that little idea helps, I do this and it works well for me.

Hi, Sam. Thank you very much for the dictionary metod, it works really fine. I have one problem though.
When I select the option "load a saved game", my data won't load, and my script simply closes.
In the menu code, I wrote something like:
if(menu_result==2)
{
load_data();
}

Does someone know which the problem could be? Should I do something in order to load my... last used function or something like that?
If I write in the following way
if(menu_result==2)
{
load_data();
courtyard();
}
Now, the function will load, and I'm on the coordinates where I saved the script last time.
But I want when I load the script, if I save in library for example, I want to be in library, not in the courtyard, or out of the script....
Or it's really necessary to write this if at every function, and then write load_data();, followed by another line with the function name where I saved the game?
Sorry if it might sound a bit crazy, but I wanted to describe my problem and what I want to do as detailed as I could.

This is the same for menus?
I have a cortyard where you move with arrow keys, and I have also some other locations like bedroom, kitchen which are menu based, and there you can change some variables as well.
Sorry if some of those questions sounds stupid, but I'm not very experienced in programming, and I'm making it just for fun in my free time.
