Saving your game on the user's PC

Ever wanted to know how to save your game on a local PC? It can be done using shared ob's. I got this code of an internetsite site:

Object.prototype.setCookie = function(c, n, v) {
var so = SharedObject.getLocal(c);
so.data[n] = v;
so.flush();
};
Object.prototype.getCookie = function(c, n) {
var so = SharedObject.getLocal(c);
return so.data[n];
};

Just let this code run once, and it will do the job (please don't ask me how it works, I don't know, it just works)

Now we can use two functions:
getCookie("name","itemname")
setCookie("name","itemname", var_to_save)

of course name stands for how to call the file, itemname is the subject in the file (you can have as many as you want) and when saving a variabele, it needs to know what to save.

As you can see, you save 1 variabele at a time. In a game, many variabeles influence the progress and need to be saved. I'm working on a game too and didn't want to save each variabele at a time.

This is where arrays come in handy.
Just think of an array as a database, it contains as many variabeles as you want.

You can declare an array in 3 ways, I use only one, because it give's the array's subjects ogical names.

_root.database = new Array(name, age, sex);

Now you have a database Array wich contains 3 variabeles.
You can acces these variabeles using _root.database.name.

After asigning vars to it, you can export it using

this.setCookie("database","item1",_root.database)

and reload it using:

_root.database = this.getCookie("database","item1")

If there's something you don't understand, check the .fla, all the code is on the mc, except for the function declaring.
The database is located in the mc too.
