adventure.js

A javascript port of the 350-point version of the classic Adventure game. I originally wrote this code as part of a Slackbot, where people could play the game by DM-ing the bot. I broke the code out of the original project so it could be reused and, well, here we are.

Playing the game

Install the game locally like:

$ npm install -g adventurejs
$ adventurejs

    Welcome to ADVENTURE!

  Original development by Willie Crowther.
  Major features added by Don Woods.
  Conversion to BDS C  by J. R. Jaeger.
  Unix standardization by Jerry D. Pohl.
  JS porting & tweaks  by Ray Myers.

Using the game through an API

You can also use this project as an API, so that the game iself can be used in all kinds of funky ways.

Installing

npm install --save adventurejs

-or-

yarn add adventurejs

Usage

Importing:

const adventure = require("adventurejs");

Starting a new game:

const game = adventure.makeState();
game.advance(); // -> ["", "    Welcome to ADVENTURE!", ...]

Note: every call to .advance() will return an array of lines to show to the user.

Advancing the game:

game.advance("no"); // <- Takes a line from the user
  // -> ["You are standing at the end of a road before a small brick", ...]
game.isDone(); // <- Returns 'true' when the game is in an irreconcilable game-over state.

Saving / Loading:

The game state object is JSON-serializable, so saving the game to file could look like:

const fs = require('fs');
fs.writeFileSync("./mygame.save", JSON.stringify(s));

The .makeState() method can accept a JS object to initialize itself, so loading could look like:

const raw = fs.readFileSync("./mygame.save", { encoding: 'utf8'});
const data = JSON.parse(raw);
const loadedGame = adventure.makeState(data);
