Dreamer of Electric Sheep

BBC-Micro-style procedurally-generated text adventure with sprites scraped from the web.


Locations and descriptions are generated from the ConceptNet database, a crowd-sourced machine-readable database of common sense knowledge about the world. Being crowd-sourced, it can contain offensive content and incorrect information. While I have done my best to blacklist the offensive content I've come across, the database is so huge that there is not much more I can feasibly do.

You can play a live version here: http://bytten-studio.com/games/dreamer/

A binary download is also linked there.

Running (download)

If you have the JAR download, ensure you have Java 1.5 installed and then simply double-click the JAR file.

You can also run it without the UI:

java -cp dreamer.jar CLI

Building (source)

Ensure you have sbt installed: www.scala-sbt.org

sbt assembly

You can also run it from source:

sbt run

The tests are currently all failing. Ignore them.

  • Fix tests - they fail right now
  • More info in html/index.html
  • Speed up spritely as much as possible: reduce search, reduce processing
  • Spritely loading/failed indication
  • Erase/delete/kill commands
  • Hint at actions the dreamer can perform while playing.
  • Referent qualifiers ("the other", "that", "this", "the first", "your", "the * from/in *", etc.)
  • More GameActions: open/close, questions (where, what).
  • Factoring Tells, e.g. "In the house, there is a cat and a dog." Might require Collection concepts.
  • Asking clarification: what, which
  • Enhancement? Add a "weird" adjective to objects spawned via dreamWeirdDefaults

Problems with ConceptNet

I intend to blog about these after #procjam finishes.

  • It can be offensive. Unfiltered, it will put gay people in closets and prostitutes in bedrooms.
  • Relations are sometimes reversed, e.g. restaurant AtLocation rice
  • No quantifiers - forall, thereexists.
  • Dual-meaning nodes: java IsA island, but java IsA program_language.
  • Lack of easily queriable transitivity.
  • HasA relationship isn't always between nouns, e.g. "The old person has a so much to teach us."
  • Related parts of the graph seem barely connected?

Good things about ConceptNet

  • The license! Hard to imagine CC-BY-SA being unacceptable to anyone reasonable.
