===================
Option Descriptions
===================

Options are accessible through the '=' command, which provides an
interface to the various sets of options available to the player.

In the descriptions below, each option is listed as the textual summary
which is shown on the "options" screen, plus the internal name of the
option in brackets, followed by a textual description of the option.

Note that the internal name of the option can be used in user pref files to
force the option to a given setting, see "customize.txt" for more info.

Various concepts are mentioned in the descriptions below, including
"disturb", (cancel any running, resting, or repeated commands, which are in
progress), "flush" (forget any keypresses waiting in the keypress queue),
"fresh" (dump any pending output to the screen), and "sub-windows" (see
below).

Interface and Display Options
=============================

.. _rogue_like_commands:

Rogue-like commands '[rogue_like_commands]'
  Selects the "roguelike" command set (see "command.txt" for info).

.. _use_old_target:

Use old target by default '[use_old_target]'
  Forces all commands which normally ask for a "direction" to use the
  current "target" if there is one. Use of this option can be dangerous if
  you target locations on the ground, unless you clear them when done.

.. _pickup_always:

Always pickup items '[pickup_always]'
  Automatically picks up items when you walk upon them, provided it is safe
  to do so.

.. _pickup_inven:

Always pickup items matching inventory '[pickup_inven]'
  Like `pickup_always`_, but picks up an item only if it is a copy of an
  item that you already have in your inventory.

.. _easy_open:

Open/Disarm/Close without direction '[easy_open]'
  If there is only one closed door next to the character, the game will not
  bother asking for a direction when the player asks to |'o'pen| omething.
  The same applies for |'c'losing| doors and |'D'isarming| traps.

.. |'o'pen| replace:: 'o'\pen

.. |'c'losing| replace:: 'c'\losing

.. |'D'isarming| replace:: 'D'\isarming

.. _center_player:

Center map continuously '[center_player]'
  The map always centres on the player with this option on. With it off, it
  is divided into 25 sections, with coordinates (0,0) to (4,4), and will
  how one section at a time - the display will "flip" to the next section
  when the player nears the edge.

.. _view_yellow_light:

Use special colors for torch-lit grids '[view_yellow_light]'
  This option causes special colors to be used for "torch-lit" grids.
  Turning this option off will slightly improve game speed.

.. _hp_changes_color:

Player color indicates low hit points '[hp_changes_color]'
  This option makes the player '@' turn various shades of colour from
  white to red, depending on percentage of HP remaining.

.. _animate_flicker:

Animate multi-coloured monsters and items '[animate_flicker]'
  Certain powerful monsters and items will shimmer in real time, i.e.
  between keypresses.

.. _purple_uniques:

Show unique monsters in a special colour '[purple_uniques]'
  All "unique" monsters will be shown in a light purple colour, which is
  not used for any "normal" monsters - so you can tell at a glance that
  they are unique. If you like the idea but don't like the colour, you can
  edit it via the "interact with colors" option.

.. _show_flavors:

Show flavors in object descriptions '[show_flavors]'
  Display "flavors" (color or variety) in object descriptions, even for
  objects whose type is known. This does not affect objects in stores.

.. _mouse_movement:

Allow mouse clicks to move the player  '[mouse_movement]'
  Clicking on the main window will be interpreted as a move command to that
  spot.

.. _mouse_buttons:

Show mouse status line buttons '[mouse_buttons]'
  Creates clickable "buttons" on the bottom line of the main window, to
  enhance mouse-led play.

.. _use_sound:

Use sound '[use_sound]'
  Turns on sound effects, if your system supports them.

Disturbance options
===================

.. _disturb_move:

Disturb whenever any monster moves '[disturb_move]'
  Disturb the player when any monster moves, appears, or disappears. This
  includes monsters which are only visible due to telepathy, so you should
  probably turn this option off if you want to "rest" near such monsters.

.. _disturb_near:

Disturb whenever viewable monster moves '[disturb_near]'
  Disturb the player when any viewable monster moves, whenever any monster
  becomes viewable for the first time, and also whenever any viewable
  monster becomes no longer viewable. This option ignores the existence of
  "telepathy" for the purpose of determining whether a monster is
  "viewable".

.. _disturb_detect:

Disturb whenever leaving trap detected area '[disturb_detect]'
  This option causes you to be disturbed when you reach the edge of your
  last invocation of detect traps.

.. _disturb_state:

Disturb whenever player state changes '[disturb_state]'
  This option causes you to be disturbed whenever the player state changes,
  including changes in hunger, resistance, confusion, etc.

.. _auto_more:

Automatically clear -more- prompts '[auto_more]'
  The game does not wait for a keypress when it comes to a '-more-'
  prompt, but carries on going.

.. _notify_recharge:

Notify on object recharge '[notify_recharge]'
  This causes the game to print a message when any rechargeable object
  (i.e. a rod or activatable weapon or armour item) finishes recharging. It
  is the equivalent of inscribing '{!!}' on all such items.

Birth options
=============

.. _birth_maximize:

Maximize effect of race/class bonuses '[birth_maximize]'
  Normally, if a character should find potions that permanently increase
  his stats, the maximum that can be achieved without equipment bonuses is
  18/100. If maximize mode is on (which is the default), then the race and
  class bonuses and penalties apply to this limit, so your half-troll will
  have a greater maximum possible strength (unassisted by his equipment)
  than a hobbit. With maximize mode off, all characters max out at 18/100
  for all stats. This also affects the start of the game, because race and
  class bonuses are applied as if they were "rings" in maximize mode (at an
  exact rate of 0/10 percentile points equals 1 point for stats over 18),
  and as "potions" in non-maximize mode (drinking six potions of [stat]
  will probably increase your stat by more than 0/60 if it was at 18 to
  start with.) To cut a long story short and a confusing explanation
  simple, you get better starting stats in non-maximize mode, but can't get
  as good at what you're supposed to be best at in the later stages of the
  game.

.. _birth_randarts:

Randomize the artifacts (except a very few) '[birth_randarts]'
  A different set of artifacts will be created, in place of the standard
  ones. This is intended primarily for people who have played enough to
  know what most of the standard artifacts do and want some variety. The
  number, findability and power of random artifacts will all match the
  tandard set - approximately.

.. _birth_keep_randarts:

Use previous set of randarts '[birth_keep_randarts]'
  Does what it says on the tin. Note that this option must be set at the
  END of the game, from the death menu. Once you have restarted the game,
  it is too late to set it (but you can still un-set it if you change your
  mind). Note that switching to non-random artifacts will wipe randarts,
  regardless of this option.

.. _birth_ai_smell:

Monsters chase recent locations '[birth_ai_smell]'
  Allow monsters to take advantage of "old" trails that you may have left
  in the dungeon.

.. _birth_ai_packs:

Monsters act smarter in groups '[birth_ai_packs]'
  "Group" monsters will use tactics that groups of monsters might
  reasonably employ - such as hiding out of sight around a corner, trying
  to draw the character out into the middle of a room so they can surround
  him and all attack at once, rather than chasing one by one down a
  corridor.

.. _birth_ai_learn:

Monsters learn from their mistakes '[birth_ai_learn]'
  Allow monsters to learn what spell attacks you are resistant to, and to
  use this information to choose the best attacks.  This option makes the
  game very difficult and is not recommended.

.. _birth_ai_cheat:

Monsters exploit players weaknesses '[birth_ai_cheat]'
  Allow monsters to know what spell attacks you are resistant to, and to
  use this information to choose the best attacks.  This option makes the 
  game very difficult and is not recommended.

.. _birth_ai_smart:

Monsters behave more intelligently (broken) '[birth_ai_smart]'
  Monsters have a certain amount of intelligence and will use it -
  teleporting away when low on hit points, using their more powerful spells
  in preference to the less powerful spells, etc. Not all monsters are, of
  course, intelligent - but those who are are almost unkillable with this
  option on (especially if they can heal themselves).

.. _birth_ironman:

Restrict the use of stairs/recall '[birth_ironman]'
  This option, not recommended for non-advanced players, prevents the
  generation of up staircases, and makes the scroll and effect of Word of
  Recall not function: and teleport-level always goes down, as does the
  spell of stair-creation, except on the quest levels of Sauron and
  Morgoth.

.. _birth_small_range:

Halve view and spell distances '[birth_small_range]'
  Distance of seeing, casting spells, shooting and so on are all halved.
  This is useful for playing with large tiles, or on small devices.

.. _birth_no_artifacts:

Restrict the creation of artifacts '[birth_no_artifacts]'
  No artifacts will be created. Ever. Just *how* masochistic are you?

.. _birth_no_stacking:

Don't stack objects on the floor '[birth_no_stacking]'
  Items dropped on the floor will spread out instead of stacking. Normal
  items will disappear if there is no empty grid within a radius of three
  squares.

.. _birth_no_preserve:

Lose artifacts when leaving level '[birth_no_preserve]'
  Normally if you leave a level with an unidentified artifact on it you may
  still find it later. With this option on, if you leave a level with an
  artifact on it's gone for the rest of the game whether you knew it was
  there or not. Note that this option has no effect on artifacts which you
  have already identified (i.e. picked up) - these will always be
  permanently lost if you leave a level without taking them with you.

.. _birth_no_stairs:

Don't generate connected stairs '[birth_no_s	tairs]'
  Never generate a staircase back to the level you came from, if you used a
  staircase to get to the level.

.. _birth_no_feelings:

Don't show level feelings '[birth_no_feelings]'
  The "quality" of a level is never revealed, no matter how long you spend
  on the level.

.. _birth_no_selling:

Items always sell for 0 gold '[birth_no_selling]'
  Shopkeepers will never pay you for items you sell, though they will still
  identify unknown items for you, and will still sell you their wares. To
  balance out income in the game, gold found in the dungeon will be
  increased if this option is on.

Cheating options
================

.. _cheat_hear:

Peek into monster creation '[cheat_hear]'
  Cheaters never win. But they can peek at monster creation.

.. _cheat_room:

Peek into dungeon creation '[cheat_room]'
  Cheaters never win. But they can peek at room creation.

.. _cheat_xtra:

Peek into something else '[cheat_xtra]'
  Cheaters never win. But they can see debugging messages.

.. _cheat_know:

Know complete monster info '[cheat_know]'
  Cheaters never win. But they can know all about monsters.

.. _cheat_live:

Allow player to avoid death    '[cheat_live]'
   Cheaters never win. But they can cheat death.

Window flags
============

Some platforms support "sub-windows", which are windows which can be used
to display useful information generally available through other means. The
best thing about these windows is that they are updated automatically
(usually) to reflect the current state of the world. The "window options"
can be used to specify what should be displayed in each window. The 
possible choices should be pretty obvious.

Display inven/equip
  Display the player inventory (and sometimes the equipment).

Display equip/inven
  Display the player equipment (and sometimes the inventory).

Display player (basic)
  Display a brief description of the character, including a breakdown of
  the current player "skills" (including attacks/shots per round).

Display player (extra)
  Display a special description of the character, including some of the
  "flags" which pertain to a character, broken down by equipment item.

Display player (compact)
  Display a brief description of the character, including a breakdown of
  the contributions of each equipment item to various resistances and
  stats.

Display map view
  Display the area around the player or around the target while targetting.
  This allows using graphical tiles in their original size.

Display messages
  Display the most recently generated "messages".

Display overhead view
  Display an overhead view of the entire dungeon level.

Display monster recall
  Display a description of the most monster which has been most recently
  attacked, targetted, or examined in some way.

Display object recall
  Display a description of the most recently selected object. Currently
  this only affects spellbooks and prayerbooks. This window flag may be
  usefully combined with others, such as "monster recall".

Display monster list
  Display a list of monsters you know about and their distance from you.

Display status
  ???

Display item list
  Display a list of items you know about and their distance from you.
 
Display borg messages
  This window flag is currently used only by the Borg.

Display borg status
  This window flag is currently used only by the Borg.

Left Over Information
=====================

The 'hitpoint_warn' value, if non-zero, is the percentage of maximal
hitpoints at which the player is warned that he may die. It is also used as
the cut-off for using the color red to display both hitpoints and mana.

The 'delay_factor' value, if non-zero, will slow down the visual effects
used for missile, bolt, beam, and ball attacks. The actual time delay is
equal to 'delay_factor' squared, in milliseconds.
