How, plz? With all the things that will be made in the agrarian game, I need to do that function.

I have the character handling program, and can use a few pointers about adding that to the conventional save option.

If you know the code, plz start from there.

Also you can look at Gazoot's dmpmaker library; but that takes a while to save a big map (my 500x500x3 map takes a good half hour when I'm not doing anything extra on my computer)
