Wow, I can’t wait to see that generator!

Ok!

It’s a bit long and not particularly smart, but here it is. The idea
was to make a sort of Ruby Choose-Your-Own adventure book, where the
computer chooses the adventure. By using variable names which made
sense in the context of the story, I could get the generator to
substitute random alternatives for nouns etc. while leaving the story
failrly easy to follow in code.

Reopening the Array class made multiple decisions very easy to program

  • man I love Ruby! In the interim testing I see my
    unique-item-from-array
    helper is not working because the arrays are not static. This makes for
    some stories with duplicate names, which isn’t nice.

I had some trouble coming up with good names for individual paragraphs
in the story tree, if you look you may see what I mean.

You have to run “story_generator.rb”.

------------------ Another run --------------------------------

A long time ago in the land of Middle-Earth there was a loyal Knight
named
Sweetcheeks. Sweetcheeks lived there with her interesting Eyebrow
Derick, and the two were pals.

Middle-Earth was in uproar because the Necronomicon, the book of the
dead, had been stolen
by the smelly witch Smythe. Smythe had hidden the book in the Batpoo
Cave and it’s presence there
would raise the dastardly Armies of Darkness at midnight!

Sweetcheeks’s plan was to recover the book of the dead and outwit the
Armies of Darkness, with Derick serving as her navigator.
While Derick memorized the layout of the Batpoo Cave, Sweetcheeks
memorized the magical words needed to safely
retrieve the Necronomicon.

Sweetcheeks and Derick spent days exploring the Batpoo Cave, stumbling
through the damp undergrowth and biting insects.
When they finally found the Necronomicon, Sweetcheeks prepared to say
the secret phrase - but could not remember it!
‘Flitzen!’ she said, pretending to remember. With a shudder the earth
split open and the Armies of Darkness rose!

Sweetcheeks and Derick beat a hasty retreat through the Batpoo Cave,
but the elders of Middle-Earth were not interested in their
excuses and drove them out to face the enemy!
In a final desperate standoff the friends remembered the magic words
and used the secret powers of the Necronomicon to defeat the Armies of
Darkness!

THE END.
