This document describes the format of the key/mouse bindings and the list
of the available commands that the binding can be set to.
The resource name for a binding consists of the following in order:
* The puzzle set name (can be "?" to apply to all puzzle sets)
* One of "editClick", "editKey", "gameClick", or "gameKey"
* Zero or more components for modifier keys (see below)
* Key name (or mouse button)
You cannot use "?" for keys, mouse buttons, or modifiers. You may,
however, use "?" in place of the edit/game selection.
Valid modifier keys are:
* shift
* ctrl
* alt
* meta
* numLock (cannot be combined with other modifiers except shift)
Most key names are lowercase, except alphabetic keys which are uppercase.
Mouse button names are "left", "middle", or "right".
The value specifies what action. The action can be one of the below:
It can be + (to advance) or - (to rewind) or = (to restart) followed by
the number of moves.
It can be ! followed by a system command.
It can be ' followed by a Hero Mesh key name, to input a move.
It can be ^ followed by one more character, to execute a command which
has ^ as the first character; if it requires an argument, the clicked
location will be used if it is clicked with the mouse.
Finally, it can be a single SQL statement. The result rows are treated as
commands to execute, where the first column is a string of two characters
(the possibilities are explained below) and the rest of the columns (if
any) are the arguments. You can use NULL for trailing arguments if you do
not need that many arguments.
SQL statements can also contain host parameters. The valid host parameters
are $X (clicked X coordinate), $Y (clicked Y coordinate), $LEVEL (level
order number), $LEVEL_ID (level ID number), $KEY_XY (ask for X and Y
coordinates, and produce a single number like the XY function does), and
any name with : at first to ask the user for the value to use.
=== Game commands ===
'' ' <key>
Input a move.
'+ ' <count>
Advance that many moves in the replay list.
'- ' <count>
Rewind that many moves.
'= ' <count>
Restart and replay that many moves.
'^<'
Rewind to mark.
'^>'
Replay to mark.
'^I'
Toggle the inventory/move-list display.
'^M'
Set the replay mark position.
'^S'
If the level is in a won state, record the solution.
'^T'
Display the level title popup.
'^d' <location>
Display the pop-up help text of the object at the location.
'^g'
Display values of global variables.
'^n' <location>
List objects at the specified coordinates in the bizarro world, to
examine their values.
'^o' <location>
List objects at the specified coordinates, to examine their values.
'^p'
Start or stop slow replay. Any move input also interrupts slow replay.
'^s'
Toggle solution replay.
'mi' <command>
Import a move list. The argument is a operating system command, that
when executed will write the move list to stdout, with one byte per
move (the Hero Mesh key codes).
'ml' <blob>
Load a move list from a SQL blob.
'mx' <command>
Export a move list. The argument is a operating system command that
will receive the move list (in the same format as above) on stdin.
'rs' <number>
Adjust replay speed by the specified number (negative to make faster, or
positive to make slower; zero leaves it unchanged).
=== Editor commands ===
'^N'
Add a new level (after the last one). The new level has the same
dimensions as the current level, but contains no objects or strings,
and the title is set to "New Level".
'^S'
Save level.
'^T'
Edit the level title.
'^a' <location>
Add an object with the current MRU values to that location, if there
is not already another object of the same class there.
'^c'
Display the class selection menu.
'^e'
Edit the currently selected MRU values. (You can only edit the direction
and the Misc values (1 to 3), not the class and image; to edit the class
and image, use the class selection menu.)
'^s'
Display the list of level strings.
'^u' <location>
Add an object with the current MRU values to that location, even if
there is already another object of the same class at that location.
'^w'
Swap the normal world with the bizarro world.
'am' <class> <image> <misc1> <misc2> <misc3> <dir>
Add a MRU and select the added MRU.
'em' <object>
Edit the Misc/Dir of an existing object.
'ex' <command>
Export a level (given the operating system command to receive the
exported data). See export.doc for details.
'im' <command>
Import a level (given the operating system command to produce the data
to be imported). See export.doc for details.
'lc' <number>
Set the level code number. This is a 16-bit number which can be used in
the class codes of your puzzle set for whatever purpose you wish; the
game engine does not use this value itself.
'lt' <blob>
Set the level title. The value must be unescaped; you can use the
HEROMESH_UNESCAPE function to do this.
'lv' <number>
Set the level version number. This number is used to detect the validity
of stored solutions. Normally, you do not need to set this; it will do
so automatically once the level is saved, if any changes have been made
which might invalidate the solution (although it doesn't know for sure,
so there are false positives). However, you can set this deliberately by
yourself, in case you know that the solution remains valid; if you do
set it by yourself just before saving, it will use your value rather
than setting it automatically.
'mR' <number>
Select a relative MRU. Negative numbers move up the list, and positive
numbers move down the list.
'mr' <number>
Select a MRU, given the MRU number (0 to 31; the top is zero).
're' <width> <height>
Remove all objects from the level and resize the level. The minimum size
is 1x1 and the maximum size is 64x64.
=== Commands available in game and editor ===
'^E'
Switch to the editor.
'^P'
Switch to the game play.
'^Q'
Quit.
'go' <level>
Go to the specified level. If the level number is negative, then it is
a level order number, otherwise it is a level ID number.
=== Mode-independent commands ===
':!' <command>
Execute a system command.
':;'
Ignore the rest of the result rows of this SQL statement.
':?' <text>
Write text to stdout.
':m' <text>
Display text on the screen, wait to push enter to continue.
':s'
Write memory allocation status to stderr.
':x'
Ask for a SQL statement, execute it, and display the results.
