====== Tyger ======

Tyger is a clone of ZZT and Super ZZT developed by Dr. Dos in the late 00s and early 10s using the Python programming language and Pygame library. 

===== Extensions =====

==== World format ====

Tyger repurposes the BoardTimeHsec field in the TWorldInfo structure as two bytes:

^ Offset ^ Type ^ Description ^
| 0x00 | byte | Tyger world selection game name color? (Unused) |
| 0x01 | byte | Tyger world selection game name length? (Unused) |

==== Scripting ====

In general, Tyger is not constrained to the limits of 16-bit ZZT counters.

Tyger adds the following OOP extensions:

  * Additional colors have defined names for use in OOP commands:
    * dblue - dark blue (color 1),
    * dgreen - dark green (color 2),
    * dcyan - dark cyan (color 3),
    * dred - dark red (color 4),
    * dpurple - dark purple (color 5)
    * dyellow - dark yellow/brown (color 6),
    * gray, grey, dwhite - light gray (color 7),
    * dgray, dgrey, dblack - dark gray (color 8),
    * black - black (color 0),
    * any - any (command-specific),
    * def - default (command-specific).
  * Additional elements have defined names for use in OOP commands:
    * edge - board edge,
    * messenger - message timer,
    * monitor - title screen monitor,
    * horizray - horizontal blink wall ray,
    * vertray - vertical blink wall ray,
    * element46 - element 46,
    * bluetext - blue text,
    * greentext - green text,
    * cyantext - cyan text,
    * redtext - red text,
    * purpletext - purple text,
    * yellowtext - yellow text,
    * whitetext - background-less text.
  * ''#become'', ''#change'' and ''#if any'' supports providing the background color as a second argument, as in ''#become fg bg element'' or ''#change fg bg element1 fg bg element2''.
  * ''#become'' and ''#change'' supports using ''any'' for a given color to re-use the tile's existing color as foreground, background, or both.
  * ''#become'' and ''#change'' supports using ''default'' for a given color to use the ZZT-defined default color as foreground, background, or both.
  * ''#char'' supports character 0. In addition, for out-of-range character values, it will resort to using character 32 instead of ignoring it (vanilla ZZT behaviour).
  * ''#cycle'' supports setting cycle 0.
  * ''#die'' creates a black-on-black instead of white-on-black empty.
  * ''#give'' and ''#take'' support giving and taking the following additional kinds:
    * ''seconds'' - the opposite of ''time'',
    * ''light'' - additional torch cycles,
    * ''invuln'' - additional energizer cycles (this also sends every object to the '':ENERGIZE'' label),
    * ''energizer'' - one energizer item's worth of cycles - use without an argument, as in ''#give energizer'',
    * ''key'' - a key - provide a key name as argument, as follows:
      * blue, darkblue - blue key,
      * green, darkgreen - green key,
      * cyan, darkcyan - cyan key,
      * red, darkred - red key,
      * purple, darkpurple - purple key,
      * yellow, darkyellow - yellow key,
      * white, gray - white key,
      * black, darkgray - black key.
  * In ''#if'', ''aligned'' can be used as a synonym for ''alligned''.
