TWIRThie

TWIRThie stands for Tree-Walker of Intrusive, Repetitive Thoughts. Twirthie is a website and Android game that has to do with my positive symptom of schizophrenia: having intrusive, repetitive thoughts. I haven't actually begun implementing the game yet. The website will (at first) be implemented entirely in HTML and JavaScript. Click on Downloads to view the Downloads web page, to download a Java program that runs on Windows, Mac, and Linux. The Java program displays random sentences similar to my intrusive/repetitive thoughts.

The website has a Generate button and a thought counter (which defaults to N = 1) at the top of the screen. Pressing Generate/Refresh displays N random sentences which all belong to my grammar of crazy thoughts. (The next paragraph not yet implemented, and when it does get implemented please skip rest of this paragraph.) All words/tokens are displayed in black, except the current word/token is displayed in red. Pressing left/right arrow selects adjacent word/token. Pressing up arrow goes to a higher level in the syntax tree. Pressing down arrow on a token beginning with a dollar sign ($) expands that token.

Tree-Walker

In normal mode, all words/tokens are displayed in black, except the current word/token is displayed in red. Pressing up arrow takes the user to rule mode, in which the enclosing rule is enclosed in red angle brackets (pressing up arrow again goes higher in the syntax tree). Pressing down arrow on a token beginning with a dollar sign ($) expands that token, going into rule mode and using the first rule (or maybe the current rule). When in rule mode, pressing right/left arrow cycles through the available rules. Pressing up arrow goes higher in the syntax tree. Pressing down arrow takes the user to normal mode, highlighting the first word/token in the current rule (unless the current rule contains one or more optional blocks, in which case the user is taken to block mode). In block mode, all optional blocks are enclosed in black square brackets, except the current optional block is enclosed in red square brackets. Pressing the space bar toggles the current optional block to be normal or empty (containing no words/tokens). Pressing right/left arrow cycles through the available optional blocks. Pressing up arrow takes the user back to rule mode. Pressing down arrow takes the user to normal mode.

Smartphone Game

The object of the Android game (which is a free download) is to parse the target sentence which belongs to my grammar of crazy thoughts and is displayed at the bottom of the screen. Random words/non-terminal symbols slowly fall down from the top of the screen and your job is to parse the target sentence (beginning with the start symbol: <sentence>). Whenever a falling word/symbol matches what you're currently parsing, it disappears and you get points (more points if multiple words/symbols are falling). If a falling symbol reaches the bottom your energy level is eroded. When the target sentence is completely parsed, a new sentence appears. Users can edit the default grammar or create a brand-new grammar, and upload those grammars to twirthie.com so other users can download them and parse those grammars within my game.

When parsing the target sentence, tapping a word matches a falling word (if any), and dragging a non-terminal symbol upwards displays a list of lower-level grammar elements. Tapping a list element selects it. Dragging a word/non-terminal symbol downwards displays a higher-level non-terminal symbol. Many details of the game have yet to be worked out.

NetLyve

One of the main goals of the Twirthie project is to act as a test bed for a much more ambitious project called NetLyve. This second project features 2 new computer languages, Lyvathon and Lyvatags, which are dialects of Python and HTML, respectively. NetLyve is a tool for creating web-based apps/games as well as Android apps and is implemented using Java. The Twirthie website will be converted into Lyvathon and Lyvatags, and the corresponding Android game will be converted into those 2 languages as well. Lyvatags does double duty as a screen layout language.
