Helen is an adventure game engine written in Java 6, designed to support multiple users. Where Helen attempts to be unique is enabling users with powerful extensibility without a grammar-heavy language (thanks to Groovy).

  • Extensible model allows powerful customization
  • Flexible grammar parsing using regex and fuzzy-match routines
  • Messaging broadcast, using grammar rewrite substitution, including "distant" messages to send to nearby rooms
  • Groovy scripting to build objects, rooms, directions, etc.
  • Verbs can be designated per location, object, or user. This allows context-sensitive logic to be available via simplified encapsulation.
