Note that some of these links should probably be the same article: for example, we probably don't need separate articles for NORTH and SOUTH, but we should have redirects to a shared article.
Also, see Special:WantedPages for an automatically-generated list of linked-to but non-existent pages.
Categories to add
- Colors
- Fake labels (:endgame, :zapped) that are rumored to exist but don't
- Output stuff: Sound? Charsets? Colors?
- World, board, stat
- Special elements/redirects: Player Clone, Dummy, Black Hole
- ZZT itself: versions, Super ZZT
- Cheats
- Locks, especially those integrated with ZZT like the SECRET flag
ZZT behavior
Some of the categorization here is fuzzy (is X a bug or a technique?). You can help by writing the corresponding article, so we can get rid of the offending line on this page. :-)
Techniques
- Kangaroo effect
- Using player clones for teleportation
- Using statless players and board edges to control teleportation
- Colors accessible from ZZT
- Detecting game speed
- Using Medusa bugs (transporters, text, etc) to prevent anti-dark cheats
- Board illusion triggered by crossing to another board and immediately hitting a passage
- Sticking non-segment entities onto a centipede
- Using non-unit step values to, e.g., move diagonally
- Stat stacking
- Transferring data between worlds by overwriting board edges
- #cycle 0 Bombs as pushable text
Internals
- Stat order
- Ticks modulo 420
- 32-command limit
- Pascal strings hold partial previous contents in memory/on disk
Bugs and limits
- Counter behavior when #giving very large numbers (32 bits in size and beyond)
- Counter display bug: some digits left behind when counter goes from big to small
- Label behavior with numerals
- #restore only restores the first label, as well as labels which have a non-alphabetic/underscore character on the line below them. Or so.
- Black keys and doors
- Inaccuracies in frequencies used by #play (two rounding bugs)
- Conveyor bugs (ability to delete player, etc)
- 1024-line maximum for all text dialogs (including world selector)
- Shooting changes step value of 150th stat
- Moving while paused via mouse movement
- Vertical blink wall can toss the player east on top of a wall/obstruction
- Blank lines in text dialogs sometimes appear as hyperlinks
- #put doesn't work on bottom row
- Built-in editor and stat deletion bugs, if we ever figure out why that one happens
- Dependencies on CPU speed for "fast" machines (e.g., sound effects)
- Koopo bug
- Can't #send to a label on the first line
- Passages have the potential to delete each other if they are adjacent
