Description

Diseases are an interesting form of spellcraft in Crossfire. Once casted, they can spread out and infect creatures in a large area. Being infected can have various effects, from amusing farts to horrible damage - almost everything is possible.

Type defined by:

object::type = 158

Attributes

Attribute	Field	Description
artifact	object::artifact	If defined, refers to an artifact to get values from.
attack type	object::attacktype	The disease will attack the host with the given <attack type>. Godpower attack type is commonly used for "unresistable" diseases.
attenuation	object::last_grace	The <attenuation> value reduces the diseases' <infectiousness> every time it infects someone new. This limits how many generations a disease can propagate.
block view	FLAG_BLOCKSVIEW	If an item is set to block view, players (and monsters) cannot see beyond it unless they cross it or manage to stand on top.
blocks prayers	blocks_prayer	Similar to damned, but does not appear in detect curse.
changing	FLAG_CHANGING	A <changing> object converts to <food> <other_arch> objects; when it's animation is done. For non-living objects <food> is checked: if it is zero, the change happens; otherwise <food> is decreased by one. I suggest you don't mess with this value - leave the default in place.
charisma	living::Cha	The player's charisma will rise by the given value while being infected. (Negative values make charisma fall)
client-sided randomized animation?	FLAG_CLIENT_ANIM_RANDOM	If defined, then the object's animation is client-sided. Similar objects are animated independently.
client-sided synchronized animation?	FLAG_CLIENT_ANIM_SYNC	If defined, then the object's animation is client-sided. Similar objects are animated synchronized.
constitution	living::Con	The player's constitution will rise by the given value while being infected. (Negative values make constitution fall)
create arch	object::other_arch	If set, the specified arch is created and dropped every time the symptoms strike. This can be various things: farts, body pieces, eggs ... Even monsters can be created that way. You could also make a disease where some exotic stuff like money/gems is created.
curing duration	living::maxgrace	The disease will last in the host for <curing duration> "disease moves" (Assuming the host survives and doesn't use a curing spell). After this period the disease is naturally cured, which provides the host with immunity from this particular disease of lower or equal level. A negative value means the disease can never be cured naturally. Note that this value can be further modulated by spell-parameters, if the disease is registered as spell in the code. Due to that, most default diseases take a lot longer to cure than it seems.
damage	living::dam	A disease with a positive <damage> value will strike the player for that amount of damage every time the symptoms occur. A negative <damage> value produces %-based damage: "<damage> -10" means the player's health is reduced by 10% every time the symptoms strike. Diseases with %-based damage can be dangerous - but not deadly - for players of all levels.
dexterity	living::Dex	The player's dexterity will rise by the given value while being infected. (Negative values make dexterity fall)
elevation	elevation	The elevation (height above sea level) of this square. It is used for weather calculations and should be in the range -32000..32000. The elevation of a tile must be set in the bottom-most game object; elevation values for non-bottom-most game objects are ignored by the Crossfire server.
exp. for curing	living::exp	When the player manages to cure this disease (with a curing spell), he is awarded with <exp. for curing> experience.
food depletion	object::last_eat	Every time the disease "moves", the player's food is reduced by the value of <food depletion>. For negative values, a %-based amount is taken.
glow radius	object::glow_radius	If <glow radius> is set to a value greater zero, the object appears lit up on dark maps. <glow radius> can be a value between 0 and 4, the higher, the more light does the object emit.
health regen.	living::hp	This value increases the player's healing rate. Negative values decrease it.
identified	FLAG_IDENTIFIED	If an item is identified, the player has full knowledge about it.
identified animation	identified_animation	If defined, then the object will take this animation when identified.
identified animation speed	identified_anim_speed	If defined, then the object will have this animation speed when identified.
identified image	identified_face	If defined, then the object will take this appareance when identified.
identified random animation?	identified_anim_random	If defined, then the object's animation is in a random sequence when identified.
identified_name	identified_name	If defined, then the object will take this name when identified.
identified_name_pl	identified_name_pl	If defined, then the object will take this plural name when identified.
image	object::face	The image-name defines what image is displayed for this object in-game.
infect race	object::race	The disease will only infect creatures of the specified <race>. "<race> *" means every creature can be infected.
infection range	object::magic	<infection range> sets the range at which infection may occur. If positive, the <infection range> is level dependant - If negative, it is not: E.g. "<infection range> -6" means creatures can be infected in six square range, and <plaque level> doesn't modify that.
infectiousness	living::wc	The <infectiousness> defines the chance of new creatures getting infected. If you set this too high, the disease is very likely to be too effective. <infectiousness>/127 is the chance of someone in range catching it.
intelligence	living::Int	The player's intelligence will rise by the given value while being infected. (Negative values make intelligence fall)
invisible	object::invisible	Generally makes the object invisible. Depending on the object-type, some can be made visible by the show_invisible spell. If in doubt, test it. Putting an invisible object under the floor always prevents it from being shown.
is used up	FLAG_IS_USED_UP	If set, decrement the <food> field at <speed>. When <food> reaches zero, remove the object.
mana depletion	living::maxsp	Every time the disease "moves", the player's mana is reduced by the value of <mana depletion>. For negative values, a %-based amount is taken.
mana regen.	living::sp	This value increases the player's rate of mana regeneration. Negative values decrease it.
material	object::material	This bitmask-value informs the player of which material(s) the object consists. Material does also affect how likely the object can be destroyed by hazardous spell-effects.
message	object::msg	This text is displayed to the player every time the symptoms strike.
moving speed	object::speed	The <speed> of the disease determines how fast the disease will "move", thus how fast the symptoms strike the host.
name	object::name	This is the name of the object, displayed to the player.
non-pickable	FLAG_NO_PICK	If set, the object cannot be picked up (Neither by players nor monsters).
number	object::nrof	This value determines the number of objects in one stack (for example: 100 gold coins => "number = 100"). You should set this at least to one, for any pickable object - otherwise it won't be mergeable into a stack.
persistence	living::maxhp	<persistence> defines how long the disease can persist OUTSIDE a host. The disease can "move" <persistence> times outside a host before it vanishes. A negative value means the disease lasts for permanent (which is only recommended to use in maps without monsters).
plaque level	object::level	The <plaque level> is proportional to the disease's deadliness. This mainly reflects in the <damage>. It has no effect on most other symptoms. Nevertheless, it is a very important value for all damage-inflicting diseases.
plural name	object::name_pl	This is the plural name of the object. A plural name must be set for all items that can be picked up and collected by the player.
power	living::Pow	The player's power will rise by the given value while being infected. (Negative values make power fall)
price adjustment	price_adjustment	If set, this is the buy and sell price adjustment ratio for the item.
price adjustment for buying	price_adjustment_buy	If set, this is the adjustment ratio when buying the item. Ignored if <price> adjustment is set.
price adjustment for selling	price_adjustment_sell	If set, this is the adjustment ratio when selling the item. Ignored if <price> adjustment is set.
progressiveness	living::ac	Every time the disease "moves" the severity of the symptoms are increased by <progressiveness>/100. (severity = 1 + (accumulated progression)/100)
slowdown penalty	object::last_sp	If set, the disease imposes a <slowdown penalty> while being infected. The player's speed is reduced by <slowdown penalty> % of normal value.
smooth level	object::smoothlevel	If <smooth level> is set to a value greater zero, the object will be drawn partially over adjacent squares having a lower <smooth level> value. The value must be between 0 and 255 (inclusive); 0 means "never overlap adjacent squares".
splitting	FLAG_SPLITTING	A <splitting> object converts to <food> <other_arch> objects; when it is hit physically. For non-living objects <food> is checked: if it is zero, the change happens; otherwise <food> is decreased by one. I suggest you don't mess with this value - leave the default in place.
strength	living::Str	The player's strength will rise by the given value while being infected. (Negative values make strength fall)
title	object::title	This is the object's title. Once an object is identified the title is attached to the name. Typical titles are "of Mostrai", "of xray vision" etc.
unpaid	FLAG_UNPAID	An <unpaid> item cannot be used unless a player carried it over a shop mat, paying the demanded price. Setting this flag makes sense only for pickable items inside shops.
value	object::value	Adds a certain value to the object: It will be worth that many times the default value from it's archetype (E.g. "value = 3" means three times worth the default value). Value for buying/selling will be further modified by various factors. Hence, testing values in-game is usually inevitable.
weight	object::weight	This value defines the object's weight in grams (1000g is 1kg). Objects with zero weight are not pickable for players. Still, set the "non-pickable"-flag for explicitly non-pickable objects (hey, this is open source... you never know ;) ).
wisdom	living::Wis	The player's wisdom will rise by the given value while being infected. (Negative values make wisdom fall)
