:stats;Stats

Many ZZT tiles, especially creatures, have
additional information, commonly called
"stats," "attributes," or "params," which
controls the behavior of those tiles. The
Stats Editor, accessed by pressing ENTER
over a tile with stats, allows you to
modify the stats for that tile.

The UP and DOWN arrow keys may be used to
select which stat to modify. ENTER often
allows you to enter a specific value for a
stat, while LEFT and RIGHT can be used to
increase and decrease a stat's value.

To see a list of all the stats on current
board, press CTRL-S to open the Stats Info
dialog. Here you can easily access any
tile with stats without needing to find it
on the board first. Even stats beyond the
edge of the board can sometimes be found
here...

:cycle;Cycle

Most creatures have a cycle speed. A cycle
of 1 is the fastest speed possible in ZZT.
Higher values make creatures move more
slowly. A cycle of 0 causes a creature to
not move at all, though it can still
inflict damage on the player when touched.

:obj;Objects and Scrolls

Objects are special creatures programmed
in the very simple ZZT-OOP (Object
Oriented Programming) language.
Scrolls use a small subset of this
language to display a message to the
player. When you edit the program or text
of either type, you will be presented with
the Object Editor, a powerful text editor
tailored specifically to ZZT-OOP
programming.

:passage;Passages

Passages allow the player to travel from
one board to another. The "passage
destination" determines which board the
player will end up on when he or she steps
into the passage.

:adv;Advanced Tweaking

Advanced tweaking allows you to finely
control a tile's stats. Modifying these
values may potentially crash ZZT.

X Step and Y Step are used to store a
direction for some tiles: pushers,
duplicators, transporters, objects, etc.
Usually only the values -1, 0, and 1 are
used, and other values can be dangerous.
For example, a pusher with an X Step of 2
and a Y Step of 0 will move two steps to
the right every cycle, traveling through
walls or other tiles without touching
them. Be careful: such a pusher can even
travel beyond the edge of the board and
cause ZZT to crash!

The three Data stats have different
meanings for each creature. Some are
usually ignored while others may represent
intelligence, duration, or something
similar. There will usually be no need to
modify these values unless you need a very
smart Tiger or Ruffian.

Objects and scrolls have a Program
Instruction stat which controls where
program execution will begin. This is
especially useful in saved games, but can
be used in regular ZZT worlds as well. A
value of zero represents the beginning of
an object's program. A value of -1 is used
for objects which have #end-ed and are not
currently executing code. Other values
represent a character offset from the
beginning of the object's program.

:bind;Bind to

One object may share another's code by
being bound to that object. Use the "Bind
to" stat to bind an object to another.
Objects which already have a program
cannot also be bound.

WARNING: ZZT may do very weird things if
you bind to something that is not an
object.

Using bind here is essentially the same as
puting a #bind command in an object's
program.

:leader;Leader and Follower

Centipedes parts move together in chains.
The leader and follower stats tell each
centipede part who to lead and who to
follow. If no values are specified, the
centipedes will usually be able to figure
this out on their own. There shouldn't
usually be any reason to modify these
values.

WARNING: ZZT may do weird things if you
lead or follow anything other than a
centipede part.
