Utopian Engine

Important note: The Utopian Engine has been put on hold. See instead phoenixfyre/UtopiaJS.

A text adventure game engine, written in Java.

Version 2.0 of the Utopian Engine features:

• A fully-fledged built-in Scripting Language, named UtopiaScript. At this time, the UtopiaScript functions are:
  • Print - Print a string to the player's console
  • Println - Same as Print, but with a trailing endline
  • Pause - Pauses the game's operation until the player presses enter
  • Description - Prints out a predefined description for the room the user is in
  • RequireItem - Require that the player possess one or more of an item to continue
  • AddItem - Give the player one or more of an item
  • TakeItem - Take one or more of an item from the player
  • RoomState - Change the state of any room to one of a predefined list of states for that room
  • GoTo x y- Send the player to any room in the game
  • Go x/y - Send the player to x rooms horizontally, and y rooms vertically (can be negative)
  • Score - Modify the user's score
  • LoadGame - LOAD A NEW GAME. Basically, I put this in for episodic gaming. More on this later.
  • QuitGame - Ends the game. Used to denote winning or losing, or just quitting. The Engine does not discriminate.
  • Inventory - Prints the user's inventory.
• JAVASCRIPT! Yes, the Utopian Engine supports JavaScript, and makes the user's input available to JavaScript for dynamic event-handling. With a bit of finagling, it is possible to make an RPG.
• Two-dimensional array of Rooms, each of which can be completely independent of one another, or modify one another
• Each Room has a list of Roomstates - when certain actions happen, developers can script the rooms to change, subtly or otherwise. Basically everything changes about the room when its state changes.

Version 2.2 of the Utopian Engine will feature:

• More UtopiaScript commands:
  • SaveState - Save a user's position, score, inventory, roomstates
  • LoadState - Load a state saved with the above
• Improved game formatting:
  • "Verb" and "object" parsing on top of existing Regular Expressions
• Option of either a two-dimensional array of Rooms, or a developer-defined web of Rooms

Version 3.0 of the Utopian Engine will feature:

• JSON instead of (most likely in addition to, for the sake of backwards-compatibility) XML
