Ruby "Save Game" function

Ruby
1

Hello!

I am currently working on a text-based RPG and I wanted to implement a
function that allowed the user to save their game at any point, so that
it could be resumed later. Of course, this would need to be complimented
by a load function that would resume the game at that previous state.

Anybody know how I would do this? :slight_smile:

Thank you in advance!

For starters, I’d suggest looking at PStore and YAML::Store.

PStore:

http://ruby-doc.org/stdlib/libdoc/pstore/rdoc/classes/PStore.html

YAML::Store exmaple:

http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/113207

PStore and YAML::Store are essentially equivalent in functionality,
the difference is PStore saves objects in Ruby’s binary marshal
format, whereas YAML::Store saves objects in human-readable YAML
text format. And the trade-off is that YAML is slower than marshal.

Further possibilities for key/value stores with Ruby:

Bill,

Thank you for the links! It’s still a lot to chew on, but I’ll try to
figure it all out. :stuck_out_tongue:

Hi,

you could try out MongoDB or CouchDB as well.
