Freeciv-Web Server Commands Freeciv server commands can change server options or affect various game behaviors also. See Server Commands for more info.

The following game settings and options are altered by using:

Freeciv-Web Server Options

aifill - Limited number of AI players
If set to a positive value, then AI players will be automatically created or removed to keep the total number of players at this amount. As more players join, these AI players will be replaced. When set to zero, all AI players will be removed.

Level: Vital. Category: Internal.

Minimum: 0, Default: 5, Maximum: 150

Value set to 7

airliftdestdivisor - Airlifting destination divisor
This sets the limit on the units a city can receive via airlift to its population divided by this number. When set to 0, the setting is toggled off.

Level: Situational. Category: Military.

Minimum: 0, Default: 0, Maximum: 20

Value set to 3 in MP rulesets.

airliftingstyle - Airlifting style
This setting affects airlifting units between cities. It can be a set of the following values: - "Allows units to be airlifted from allied cities" (FROM_ALLIES). - "Allows units to be airlifted to allied cities" (TO_ALLIES). - "Unlimited units from source city" (SRC_UNLIMITED): note that airlifting from a city doesn't reduce the airlifted counter, but still needs at least 1. - "Unlimited units to destination city" (DEST_UNLIMITED): note that airlifting to a city doesn't reduce the airlifted counter, and doesn't need any.

Level: Situational. Category: Military.

Possible values (option can take any number of these):  FROM_ALLIES: "Allows units to be airlifted from allied cities"  TO_ALLIES: "Allows units to be airlifted to allied cities"  SRC_UNLIMITED: "Unlimited units from source city"  DEST_UNLIMITED: "Unlimited units to destination city" Default: empty value

allowtake - Players that users are allowed to take
This should be a string of characters, each of which specifies a type or status of a civilization (player). Clients will only be permitted to take or observe those players which match one of the specified letters. This only affects future uses of the "take" or "observe" commands; it is not retroactive. The characters and their meanings are: o,O = Global observer b  = Barbarian players d  = Dead players a,A = AI players h,H = Human players The first description on this list which matches a player is the one which applies. Thus 'd' does not include dead barbarians, 'a' does not include dead AI players, and so on. Upper case letters apply before the game has started, lower case letters afterwards. Each character above may be followed by one of the following numbers to allow or restrict the manner of connection: (none) = Controller allowed, observers allowed, can displace connections. (Displacing a connection means that you may take over a player, even when another user already controls that player.) 1 = Controller allowed, observers allowed, can't displace connections; 2 = Controller allowed, no observers allowed, can displace connections; 3 = Controller allowed, no observers allowed, can't displace connections; 4 = No controller allowed, observers allowed

Level: Rare. Category: Networking.

Default: "HAhadOo"

alltemperate - All the map is temperate

Level: Rare. Category: Geological.

Default: disabled

animals - Amount of animals
Amount of animals initially created to terrains defined for them in the ruleset. The server variable's scale is animals per thousand tiles.

Level: Vital. Category: Geological.

Minimum: 0, Default: 20, Maximum: 500

aqueductloss - Percentage food lost when city can't grow
If a city would expand, but it can't because it lacks some prerequisite (traditionally an Aqueduct or Sewer System), this is the base percentage of its foodbox that is lost each turn; the penalty may be reduced by buildings or other circumstances, depending on the ruleset.

Level: Rare. Category: Economic.

Minimum: 0, Default: 0, Maximum: 100

armisticelength - Length of Armistice before Peace
This setting sets the turn length of the Armistice that occurs when two nations agree to a Peace treaty. Armistice is a state that comes when agreeing to Peace, in which units that may be in the other nation's territory are given a certain number of turns to vacate the territory without that possibly being grounds for casus belli or the movement being disallowed without first declaring war.

Level: Situational. Category: Military.

Minimum: 1, Default: 16, Maximum: 100

autoattack - Turn on/off server-side autoattack

Default: disabled

autoattack_style - Style for server side autoattack.
How the setting 'autoattack' behaves, if enabled. (Some rulesets depend on non-default settings for this, in order to elicit intended behavior from units.) Level: Situational. Category: Military. 0: ➤ DEFAULT:  Units on adjacent tiles generally attack enemy units if they have better odds attacking than defending, OR if the enemy has the flag "Provoking". Exception: a single unit in a city not wanting to leave the city undefended if it loses.

1: ➤ PROVOKED_ONLY: "Provoking" units ONLY will be autoattacked. Rulesets use "will_never" and "Provoking'" flags to make reqs for which units proactively attack specific types. Only units with the Vigil order will autoattack, giving players tactical control. This is used to minimize 'baiting' and other unnatural dynamics: e.g., a ruleset can be coded so that only Fighters auto-attack other Air units,

Default: 0

blueprints - Replace tech transfers with blueprint transfers.
To function, this setting needs 'multiresearch' to be enabled.

Trade, Theft, Conquest, Philosophy, etc. WILL NOT instantly give you technology. Instead, you get technology Blueprints, which are a bulb-credit toward one specific tech. Blueprints reduce the bulb cost of a tech by a percentage. If blueprints=80 and Gunpowder=1000 bulbs, then Gunpowder Blueprints reduce cost to 200 bulbs.

Level: Rare. Category: Scientific. Situational override settings: diplbulbcost for TECH TRADE; conquercost for THEFT, CONQUEST; freecost for PHILOSOPHY, HUTS, GREAT LIBRARY, etc.

Minimum: 0, Default: 0 (off), Maximum: 100. Needs  to function.
 * Examples:
 * . Sets Blueprints to 80% for tech trades.
 * . Sets Blueprints to 90% for theft and conquest.

casusbelli_allies - Whether casus belli is also given to a nation's allies.
Under the default setting (0), casus belli may not be given to the allies of a nation when war is declared on it or when an action is done which gives it casus belli. With the setting value of 1, "an attack on one is an attack on all." Any declaration of war or action which gives casus belli to a nation, will also give casus belli to all of that nation's allies.

Level: Situational. Category: Military.

Minimum: 0, Default: 0, Maximum: 1

casusbelliturns - Length in turns of a first casus belli before it expires.
If there is already a state of casus belli, additional incidents will simply refresh it to this value; or, if it is already this value or greater, add an additional turn to the length.

NOTE: any new non-aggression treaty made after casus belli is considered to supersede violations of past treaties and eliminate casus belli. Thus, players may re-affirm a treaty that has casus belli on it, and eliminate the casus belli status of that treaty.

Level: Situational. Category: Military.

Minimum: 1, Default: 15, Maximum: 1000

ceasefirelength - Length of Cease-Fire treaties

A value of 1 removes any such restriction on city placement.

Level: Situational. Category: Sociological.

Minimum: 1, Default: 2, Maximum: 11

Value set to 3

city_output_style - Whether to replace city output behavior with WYSIWYG
The value of this setting regulates the order in which city output is calculated. Possible values:

0. Legacy: A. When a city grows or shrinks, citizens are auto-assigned to new tiles and specialists AFTER food, shields, and luxury are accumulated; but BEFORE science and gold are accumulated. This gives an exploitable bonus to growing cities, but overrides the science and gold output of tiles and specialists that were selected before the city grew or shrank. B. Food and gold upkeep on newly created units and buildings is deducted at the instant of creation, but shield upkeep is deducted on the first Turn Change after the unit's creation.

1. WYSIWYG "What you see is what you get": A. All city outputs are calculated by the tiles and specialists the city assigned before growing or shrinking, unless a new city improvement adds a bonus and/or increases gold upkeep. B. All unit upkeeps are uniformly paid on the first Turn Change AFTER a new unit's creation.

2. Strict WYSIWYG: The same as WYSIWYG except ALL unit and building upkeep is uniformly deferred and deducted on the first Turn Change AFTER creation. This means buildings get bonus effects on the first turn of existence, with no upkeep on that turn.

Minimum: -5, Default: 0, Maximum: 6

mgr_foodneeded - Whether migration is limited by food
If this setting is enabled, citizens will not migrate to cities which would not have enough food to support them. This setting has no effect unless migration is enabled by the 'migration' setting.

Level: Rare. Category: Sociological.

Default: enabled

mgr_nationchance - Percent probability for migration within the same nation
This setting controls how likely it is for citizens to migrate between cities owned by the same player. Zero indicates migration will never occur, 100 means that migration will always occur if the citizens find a suitable destination. This setting has no effect unless migration is activated by the 'migration' setting.

Level: Rare. Category: Sociological.

Minimum: 0, Default: 50, Maximum: 100

mgr_turninterval - Number of turns between migrations from a city
This setting controls the number of turns between migration checks for a given city. The interval is calculated from the founding turn of the city. So for example if this setting is 5, citizens will look for a suitable migration destination every five turns from the founding of their current city. Migration will never occur the same turn that a city is built. This setting has no effect unless migration is enabled by the 'migration' setting.

Level: Rare. Category: Sociological.

Minimum: 1, Default: 5, Maximum: 100

mgr_worldchance - Percent probability for migration between foreign cities
This setting controls how likely it is for migration to occur between cities owned by different players. Zero indicates migration will never occur, 100 means that citizens will always migrate if they find a suitable destination. This setting has no effect if migration is not enabled by the 'migration' setting.

Level: Rare. Category: Sociological.

Minimum: 0, Default: 10, Maximum: 100

migration - Whether to enable citizen migration
This is the master setting that controls whether citizen migration is active in the game. If enabled, citizens may automatically move from less desirable cities to more desirable ones. The "desirability" of a given city is calculated from a number of factors. In general larger cities with more income and improvements will be preferred. Citizens will never migrate out of the capital, or cause a wonder to be lost by disbanding a city. A number of other settings control how migration behaves: 'mgr_turninterval' - How often citizens try to migrate. 'mgr_foodneeded'  - Whether destination food is checked. 'mgr_distance'    - How far citizens will migrate. 'mgr_worldchance' - Chance for inter-nation migration. 'mgr_nationchance' - Chance for intra-nation migration.

Minimum: 0, Default: 1, Maximum: 150

move_bonus_in_frags - move bonuses are applied in fragments (not whole moves.)
If this is enabled, the ruleset applies move bonuses in fragments instead of whole moves. This allows it to award partial movement points as a bonus.

Category: Military.

This setting is only intended to be set inside a ruleset.

Default: set by ruleset.

multiresearch - Allow research to invest bulbs in multiple technologies
With this setting on, accumulated bulbs in an undiscovered technology can never transfer to new technology. Instead, each bulb that was researched in any specific technology, is permanently assigned to that specific technology.

The techpenalty setting is made useless if this option is enabled, since no bulbs are ever transferred from one tech to another tech.

Category: Scientific.

Possible Values:

ENABLED: on, DISABLED: off.

Default: DISABLED, or set by ruleset.

nationset - Set of nations to choose from
Controls the set of nations allowed in the game. The choices are defined by the ruleset. Only nations in the set selected here will be allowed in any circumstances, including new players and civil war; small sets may thus limit the number of players in a game. If this is left blank, the ruleset's default nation set is used. See '/list nationsets' for possible choices for the currently loaded ruleset.

Minimum: 0, Default: 0, Maximum: 49

nuclearwinter - Nuclear winter
If set to 0, Nuclear Winter will not occur from the uncleaned nuclear fallout caused by nuclear explosions. Otherwise, this setting modifies the strength of nuclear winter: the accumulated climate stress added each turn, which also affects how many tiles will be transformed. 100 is standard. Lower is less, higher is more.

This setting does not affect likelihood of nuclear fallout from detonation.

Level: Vital. Category: Geological.

Default: enabled

nuclearwinter_percent - strength of nuclear winter effect
The percentage by which to modify the default strength of nuclear winter sensitivity. Specifically, a lower value causes a higher threshold for Fallout to trigger Nuclear Winter, and also causes a higher rate of ecologically absorbing the cumulative climactic impact on each turn.

Level: Vital. Category: Geological.

Default: 100

nukes_major - Allow nuclear detonations
Allow players to create major thermonuclear weapons. If turned off, this will have no effect on standard fission nuclear weapons; but in rulesets which require this setting to be on for thermonuclear fusion weapons, they will be disallowed for the current game. If turn on, rulesets which require this setting for the creation of advanced fusion weapons will allow them to be created in that particular game.

Level: Vital. Category: Military.

Default: enabled

nukes_minor - Allow nuclear detonations
If turned off, will not allow detonating nukes in rulesets which require the setting to be on in order to detonate nukes. In all rulesets, this setting turn on will allow nuclear detonations and (in some rulesets) the creation of units considered to be "minor nukes." See also: nukes_major

Level: Vital. Category: Military.

Default: enabled

occupychance - Chance of moving into tile after attack
If set to 0, combat is Civ1/2-style (when you attack, you remain in place). If set to 100, attacking units will always move into the tile they attacked when they win the combat (and no enemy units remain in the tile). If set to a value between 0 and 100, this will be used as the percent chance of "occupying" territory.

Level: Rare. Category: Networking.

Possible values: Minimum: 0, Maximum: 1000, Default: 13

pax_dei_set- Whether the game considers Pax Dei in effect at game start.
Usually, this gets set in a game when the Pax Dei wonder is built. " However, it is possible to enable 'pax_dei_set' at game start. This activates the ruleset effects for the Pax Dei wonder at game start, for exactly 'pax_dei_counter' # of turns. Note: this intentionally disallows Pax Dei from being made by any player. Thus, this setting can be used to enable Pax Dei wonder effects at game start and/or completely disable the Pax Dei wonder in the current game (if 'pax_dei_counter' is set to 0.) Also see: 'pax_dei_counter'.

Level: Rare. Category: Military.

Possible values: DISABLED: "Not set at game start", ENABLED: "Set at game start. Disallow building wonder." Default: "Disabled" (DISABLED)

persistentready - When the Readiness of a player gets autotoggled off

plrcolormode - How to pick player colors
This setting determines how player colors are chosen. Player colors are used in the Nations report, for national borders on the map, and so on. - "Per-player, in order" (PLR_ORDER): colors are assigned to individual players in order from a list defined by the ruleset. - "Per-player, random" (PLR_RANDOM): colors are assigned to individual players randomly from the set defined by the ruleset. - "Set manually" (PLR_SET): colors can be set with the 'playercolor' command before the game starts; these are not restricted to the ruleset colors. Any players for which no color is set when the game starts get a random color from the ruleset. - "Per-team, in order" (TEAM_ORDER): colors are assigned to teams from the list in the ruleset. Every player on the same team gets the same color. - "Per-nation, in order" (NATION_ORDER): if the ruleset defines a color for a player's nation, the player takes that color. Any players whose nations don't have associated colors get a random color from the list in the ruleset. Regardless of this setting, individual player colors can be changed after the game starts with the 'playercolor' command.

slot_control - Ruleset can specify which units can use extra City_Build_Slots
If this is turned on, cities which can build more than one unit per turn can only do so for units which have the utype flag "SHIELD2GOLD". This should get its own custom flag later but for now it works in rulesets which use S2G as the balancing factor to encourage higher population of certain units (such as infantry), vis-à-vis the game's artificial scarcity of City_Build_Slots.

See the 'generator' setting. - "One player per continent" (SINGLE): one player is placed on each of a set of continents of approximately equivalent value (if possible). - "Two or three players per continent" (2or3): similar to SINGLE except that two players will be placed on each continent, with three on the 'best' continent if there is an odd number of players. - "All players on a single continent" (ALL): all players will start on the 'best' available continent. - "Depending on size of continents" (VARIABLE): players will be placed on the 'best' available continents such that, as far as possible, the number of players on each continent is proportional to its value. If the server cannot satisfy the requested setting due to there being too many players for continents, it may fall back to one of the others. (However, map generators try to create the right number of continents for the choice of this 'startpos' setting and the number of players, so this is unlikely to occur.)

Level: Rare. Category: Sociological. Is locked by the ruleset.

Possible values: FIXED: "Fixed" EVEN: "Even" Default: "Fixed" (FIXED)

turnblock - Turn-blocking game play mode
If this is turned on, the game turn is not advanced until all players have finished their turn, including disconnected players.

Level: Situational. Category: Internal.

Default: enabled

unitwaittime - Minimum time between unit actions over turn change
This setting gives the minimum amount of time in seconds between unit moves and other significant actions (such as building cities) after a turn change occurs. For example, if this setting is set to 20 and a unit moves 5 seconds before the turn change, it will not be able to move or act in the next turn for at least 15 seconds. This value is limited to a maximum value of 2/3 'timeout'.

Also see: 'unitwaittime_style', 'fortifywaittime'

Level: Vital. Category: Internal.

Minimum: 0, Default: 0, Maximum: 8639999

unitwaittime_style - Unitwaittime style
Affects wait time behaviours if 'unitwaittime' is set.

Any/all/none of the following values may be set:

"Activities" (ACTIVITIES): Units who moved less than 'unitwaittime' seconds before Turn Change will complete tile modifications immediately after 'unitwaittime' expires. (Roads, forts, etc.)

"Fortify" (FORTIFY): Units who fortify less than 'fortifywaittime' seconds before Turn Change will become fortified after 'fortifywaittime' expires.

"DelayGoto" (DELAYGOTO): When 'unitwaittime' prevents a unit from moving, movement will be delayed until after 'unitwaittime' expires (instead of cancelled).

Level: Vital. Category: Internal.

Minimum: 0, Default: 0, Maximum: 8639999

universal_unload - Transported units unload the same regardless of tile nativity
This makes all transported units affected by terrain speed unload with the same behavior: unloading from native tiles behaves the same as unloading from non-native. This limits double-move issues in games which allow transporting units on rivers, canals, rails, or other native tiles. Units with the BeachLander flag aren't affected by this option.

Category: Military.

Default: set by ruleset

unload_override - Move fragment cost for unloading from native tiles
When universal_unload is enabled, this option overrides the move fragment cost that universal_unload adds, when transported units unload from a native tile. If zero, this option is off.

Category: Military.

Minimum: 0, Default: 0, Maximum: 1000

unreachableprotects - Does unreachable unit protect reachable ones
This option controls whether tiles with both unreachable and reachable units can be attacked. If disabled, any tile with reachable units can be attacked. If enabled, tiles with an unreachable unit in them cannot be attacked.

Level: Rare. Category: Military.

Default: enabled

victories - What kinds of victories are possible
This setting controls how game can be won. One can always win by conquering entire planet, but other victory conditions can be enabled or disabled: - "Spacerace" (SPACERACE): Spaceship is built and travels to Alpha Centauri. - "Allied" (ALLIED): After defeating enemies, all remaining players are allied. - "Culture" (CULTURE): Player meets ruleset defined cultural domination criteria.

Level: Vital. Category: Internal.

Possible values (option can take any number of these): SPACERACE: "Spacerace" ALLIED: "Allied victory" CULTURE: "Culture victory" Default: "Spacerace" and "Allied victory" (SPACERACE|ALLIED)

wetness - Amount of water on landmasses
Small values mean lots of dry, desert-like land; higher values give a wetter map with more swamps, jungles, and rivers.

Level: Situational. Category: Geological.

Minimum: 0, Default: 50, Maximum: 100

xsize - Map width in tiles
Defines the map width. For this option to take effect, the "Map size definition" option ('mapsize') must be set to "Width and height" (XYSIZE).

Level: Vital. Category: Geological.

Minimum: 16, Default: 64, Maximum: 128000

ysize - Map height in tiles
Defines the map height. For this option to take effect, the "Map size definition" option ('mapsize') must be set to "Width and height" (XYSIZE).

Level: Vital. Category: Geological.

Minimum: 16, Default: 64, Maximum: 128000

zoc_purity - Whether units who ignore ZoC lift ZOC for units who don't ignore ZoC.
If enabled, igZOC units do not negate ZOC for other units. This decreases exploits and increases importance of tactical positioning, notably in games with RestrictINFRA off.

Level: Situational. Category: Military. Default: disabled
