README.md

Untrusted —or— the Continuing Adventures of Dr. Eval is an exciting Meta-JavaScript Adventure Game wherein you guide the dashing, steadfast Dr. Eval through a mysterious MACHINE CONTINUUM, wherein, using only his trusty computer and the TURING-COMPLETE power of JavaScript, he must literally ALTER HIS REALITY in order to find his freedom! You must literally edit and re-execute the very JavaScript running the game in your browser to save Dr. Eval from this dark and confusing reality!

Overview

The game presents you with a roguelike-like playing environment and a console window with the JavaScript code generating each level. As loaded, each level is unbeatable, and most of the JavaScript is blocked from editing. The challenge is to open a path to the next level using only the limited tools left open to you.

Development

Run

make

to merge the JavaScript files into scripts/build/untrusted.js (and enables debug features).

make release

merges and minifies the JavaScript files into scripts/build/untrusted.min.js (and disables debug features).

To run the game locally, you need to set up a local server to serve index.html (this step is necessary due to Access-Control-Allow-Origin restrictions).

First install http-server if you haven't already:

npm install http-server

Then run:

make runlocal

Build your own mod in the mods directory:

make mod=example_mod

Contributing Levels

To add a new level, create a jsx file in /levels/bonus and add the level filename to the bonusLevels array in game.js.

If you are adding any new commands that the player can use, make sure to add them to reference.js.

The .jsx file format

jsx files are like regular JavaScript files, but have some additional syntax:

  • #BEGIN_EDITABLE# and #END_EDITABLE# surround editable lines
  • #{# and #}# wrap editable sections (parts of lines)
  • #BEGIN_PROPERTIES# and #END_PROPERTIES# surround the properties object at the start of the file. Available properties include:
    • commandsIntroduced: array of new commands introduced in the level (see reference.js)
    • mapProperties: optionally contains any of the following:
      • allowOverwrite: if true, placed static objects can be overwritten by other objects
      • keyDelay: specifies the lag, in milliseconds, between player keystrokes (default: 0)
      • quickValidateCallback: speeds up validation of callback methods at the cost of some security (useful for levels with very many dynamic objects)
      • refreshRate: the refresh rate of the level, in milliseconds (required for dynamic objects with interval properties to work correctly)
      • showDrawingCanvas: if true, the drawing canvas overlay is displayed
      • showDummyDom: if true, a dummy DOM will be displayed instead of the regular map
    • music: name of the background track for the level (see music.js)
    • startingMessage: message displayed at the bottom of the screen when the level starts (if any)
    • version: increase the level version whenever you update a level
  • #START_OF_START_LEVEL# and #END_OF_START_LEVEL# should be the first and last line of the startLevel method, respectively
