Legacy GM [Solved]Storing a ds_grid in an ini file

[Quinnlan Varcoe]

Is there any way to store a ds_grid in an ini file? I have tried this way:

scr_savegame

if (file_exists("Save.sav")) file_delete("Save.sav");
ini_open("Save.sav");
for (var yy = 0; yy < obj_inventory.height; yy++;) {
    for (var xx = 0; xx < obj_inventory.width; xx++;) {
        ini_write_real(string(xx), string(yy), obj_inventory.box[# xx, yy]);
        ini_write_real(string(xx), string(yy), obj_inventory.count[# xx, yy]);
    }
}
ini_close();

scr_loadgame

ini_open("Save.sav");
ds_grid_clear(obj_inventory.box, item.none);
ds_grid_clear(obj_inventory.count, item.none);
for (var yy = 0; yy < obj_inventory.height; yy++;) {
    for (var xx = 0; xx < obj_inventory.width; xx++;) {
    obj_inventory.box[# xx, yy] = ini_read_real(string(xx), string(yy), 0);
    obj_inventory.count[# xx, yy] = ini_read_real(string(xx), string(yy), 0);
    }
}
ini_close();

Convert the map's data into a string and write that to the INI file.

http://docs.yoyogames.com/source/dadiospice/002_reference/data structures/ds maps/ds_map_write.html

When needed, read the string from the INI file and convert it back to a map.

http://docs.yoyogames.com/source/dadiospice/002_reference/data structures/ds maps/ds_map_read.html

There are other viable options as well. The ds_map_secure_*() functions are pretty good at what they do.

Thanks!

However I am still getting some issues.

scr_savegame

if (file_exists("Save.sav")) file_delete("Save.sav");
ini_open("Save.sav");
var box_string;
var count_string;
box_string = ds_map_write(obj_inventory.box);
count_string = ds_map_write(obj_inventory.count);

ini_write_string("Saved", "0", box_string);
ini_write_string("Saved", "1", count_string);
ini_close();

Upon running this script:

Simply use ds_grid_write and ds_grid read to convert to string.

This can then be saves in a ds_map with secure save for example.

Loading is then only openening the map with ds_secure_load, and convert to a previosuly created

my_grid=ds_grid_create(ww,hh) // make it easy on yourself and grab ww,hh from the map (seperate keys)
ds_grid_read(my_grid,map[? "grid"]); // returns decoded grid - dont forget to destroy later on ;)

EDIT: to answer your question directly im gonna copy paste from the official documentation:

ini_open("Save.ini");
ini_write_string("Save", "0", ds_grid_write(mygrid));
ini_close();

As a sidenote: you do can do the same thing with ALL datastructures - they have read / write to string functions. No arrays, though at least not directly (!), there are ways to do it...

Keep in mind too, if I'm not mistaken, ini files have a size limit that can easily be exceeded by a fairly large grid. Using ds_map_secure is almost as easy an using ini files and doesn't have the size limit.

Thanks everyone,

I decided to go with the secure load and save feature. However now I'm receiving this error report.

Didn't your original method(with for loops) work? I'm using that, is it unoptimized coding or...?

 

[Quinnlan Varcoe]

Doesnt work.

 

[YanBG]

Did you open the ini(with text editor) and see if all is written in there? If all is in there then the save part works and it has to be the load.

 

[Aura]

Pffft, my bad; you're trying to save and load data from a grid and I told you about the functions meant for maps. ^^"

http://docs.yoyogames.com/source/dadiospice/002_reference/data structures/ds grids/ds_grid_read.html

http://docs.yoyogames.com/source/da...e/data structures/ds grids/ds_grid_write.html

At this point, @stainedofmind is right. INI files have a maximum size limit (64 KB iirc) so you should use text files instead.

Thanks, this helped a bit more, I was confused on why the secure save functions werent working!
