Editing Deterioration

'''Deterioration''' is the gradual loss of the health (hit points) of certain items. An item is anything that can be hauled by a colonist. Deterioration is akin to an item taking damage from projectiles, explosions, or fire since they all affect the same health stat. Affected items include [[clothing]], [[armor]], [[weapons]], and most [[resources]]. Deterioration is applied to an item on the ground that is not under a roof. An [[Equipment_Rack|equipment rack]] provides protection for clothing and armor. Whether the item is indoors or outdoors does not matter, therefore a roofed room without a door still provides protection. Mountains have an indestructible roof making them well-suited to protect perishable items. 

When an item's health reaches 0 it is destroyed.

''Special notes:''

Deterioration is also applied to apparel (armor and clothing) when worn. A colonist wearing any apparel with health 20% or below will get the 'Wearing tattered apparel' thought. A colonist wearing any apparel with health between 21% and 50% will get the 'Wearing frayed apparel' thought.

Artillery shells that deteriorate to 0 health will explode.

Raw food deteriorates in addition to still being prone to spoilage.

As an item loses health it also loses it's [[Market_Value|market value]] very quickly. Items lose other stats as well:

* Apparel suffers lowered armor protection and insulation. 

* Ranged weapons suffer lowered accuracy. 

* Melee weapons suffer lowered melee damage. 

==Deterioration Rate==
An item's [[Deterioration_Rate|deterioration rate]] specifies how much health is lost per day. Depending on the type of item it ranges from 0.25/d to 10.0/d. This stat is listed in an item's information tab. If this stat is not listed then the item will not deteriorate. Rain greatly affects deterioration rate. 

Meals have a deterioration rate of 10.0/d. Therefore, packaged survival meals which needed no special care before deterioration was introduced, now will decay quickly without protection.

==Immunity==
Resources that are immune to deterioration are [[Metallic_Materials|metal]], [[Stony_Materials|stone]], leather, and [[Hyperweave|hyperweave cloth]]. However, items crafted from these materials do not carry over that immunity.

[[Medicine#Glitterworld_Medicine|Glitterworld medicine]] is also immune.

-== Summary ==
+When an item's health reaches 0 it is destroyed.
-'''Deterioration''' is the gradual loss of the [[Max Hit Points|Hit Points]] applied to a susceptible item that is not placed in a safe place. Deterioration is akin to an item taking damage from projectiles, explosions, or [[fire]] - they all lower the same HP total, so they all stack with each other.
-Susceptible items include [[clothing]], [[armor]], [[weapons]], and most [[resources]]. When an item's hit points reach 0, it is destroyed. Deterioration does not impact the protective stats of armor, weapon function or quality of item. See [[#Effects of deterioration]] for details.

+''Special notes:''
-* When an item in [[Stockpile zone|storage]] is destroyed by deterioriation a pop-up message will display saying: ''<ITEM NAME> has deteriorated away in storage.''
+Deterioration is also applied to apparel (armor and clothing) when worn. A colonist wearing any apparel with health 20% or below will get the 'Wearing tattered apparel' thought. A colonist wearing any apparel with health between 21% and 50% will get the 'Wearing frayed apparel' thought.
-* When an item being worn by a pawn is destroyed by deterioriation a pop-up message will display saying: ''<ITEM NAME> worn by <PAWN NAME> deteriorated away to nothing.''
-Deterioration and the spoilage of [[food]] and [[corpse]]s due to [[temperature]] are completely independent from each other. Both systems run in parallel according to their own mechanics and do not interact unless they cause the destruction of the item in question.
+Artillery shells that deteriorate to 0 health will explode.
-=== Deterioration rate ===
+Raw food deteriorates in addition to still being prone to spoilage.
-An item's [[Deterioration Rate|deterioration rate]] specifies how many hit points are lost per day, while left either [[roof|unroofed]] or outdoors. For example, [[packaged survival meal]]s deteriorate at 0.25 HP/day, while [[rice]] deteriorates at 6 HP / day. This stat is listed in an item's information tab. For items with the [[quality]] stat, a high-quality item will have a lower deterioration rate than a poor quality item (see [[Quality#General]] for details). If this stat is not listed or listed as '0.00/d', then the item will not deteriorate.
-Deterioration rate is then multiplied by being in [[rain]] (x5) or being placed in [[Terrain|watery terrain]] (x3 on marsh or any water tile). Items placed indoors do not deteriorate. Items placed in a [[shelf]] do not deteriorate even when otherwise in conditions that would cause deterioration. Equipped [[apparel]] - both [[clothing]] and [[armor]] - deteriorate when worn. Equipped [[weapons]] and [[utility]] items do not deteriorate.
+As an item loses health it also loses it's [[Market_Value|market value]] very quickly. Items lose other stats as well:
-=== Immunity to deterioration ===
+* Apparel suffers lowered armor protection and insulation.
-Several items are immune to deterioration. Note that items crafted from these materials do not neccessarily carry over that immunity however.
-Immune items include:
+* Ranged weapons suffer lowered accuracy.
-* [[Metals]]
-* [[Stone]]
-* [[Persona core]]
-* [[Artifact]]s
-* Minified [[furniture]] and [[buildings]]
-=== Effects of deterioration ===
+* Melee weapons suffer lowered melee damage.

-As an item loses hit points, it may also lose its [[Market Value|market value]]. This only applies to items which have not been configured to ignore health when determining price.  The XML tag for this is ''healthAffectsPrice'', which defaults to ''true'' if not explicitly set in the def or a parent of the def.  This is set, for most items, in the base definition from which the item inherits its properties.
-Items that do ''not'' decrease in market value with HP loss include:
+==Deterioration Rate==
-* [[Wood]] (and technically [[metals]] and [[jade]] have the healthAffectsPrice tag too, but they don't use HP so it's irrelevant)
+An item's [[Deterioration_Rate|deterioration rate]] specifies how much health is lost per day. Depending on the type of item it ranges from 0.25/d to 10.0/d. This stat is listed in an item's information tab. If this stat is not listed then the item will not deteriorate. Rain greatly affects deterioration rate.
-* [[Textiles]]
-* Raw plant matter such as [[hops]], [[psychoid leaves]] and [[smokeleaf leaves]]; and also including [[wort]]
-* Raw animal products such as [[milk]], [[insect jelly]], [[eggs]]
-* [[Meal]]s including [[pemmican]] and [[kibble]]
-* [[Drug]]s
-* [[Medicine]] (including [[neutroamine]])
-* [[Component]]s and [[Advanced component]]s
-* [[Chemfuel]]

-* [[Genepack]]s{{BiotechIcon}} and [[xenogerm]]s{{BiotechIcon}}
-If an item loses value with hit points, it loses that value very quickly.  An item retains 100% of its value down to 90% HP, then loses 1.67% of its maximum value per 1% HP lost between 90% and 60% HP, then loses ''4%'' if its maximum value per 1% HP lost between 60% and 50% HP, then loses 0.2% of its maximum value per 1% HP lost between 50% and 0% HP.  The item will have 50% of its maximum value at 60% HP and only 10% of its maximum value at 50% HP.
+Meals have a deterioration rate of 10.0/d. Therefore, packaged survival meals which needed no special care before deterioration was introduced, now will decay quickly without protection.
-The only other effect of HP loss is the effect on [[mood]] of a pawn using a damaged item. A [[human]] wearing ''any'' apparel with hit points 50% or below will get the {{--|3}} [[thought]] ''[[Mood#Ratty apparel|Ratty Apparel]]''. If ''any'' worn item is below 25%, the thought will worsen to a {{--|5}} ''[[Mood#Tattered apparel|Tattered Apparel]]''. Compare them with {{--|6}} ''[[Mood#Naked|Naked]]'' thought. A pawn does not receive negative thoughts for using deteriorated weapons.
+==Immunity==
+Resources that are immune to deterioration are [[Metallic_Materials|metal]], [[Stony_Materials|stone]], leather, and [[Hyperweave|hyperweave cloth]]. However, items crafted from these materials do not carry over that immunity.
-Other than market value, potential mood effects, and hastening the item's destruction, an item's loss of HP does not affect any other stats, including damage output, accuracy, armor value, heat or cold insulation, [[nutrition]], [[flammability]], [[beauty]], [[comfort]], medical potency or [[quality]], etc.  In addition, a finished product is not influenced in any way by the deterioration of its ingredients, including in market value or chance of success.
+[[Medicine#Glitterworld_Medicine|Glitterworld medicine]] is also immune.
-== Analysis ==
-{{stub|section=1|reason=Expansion needed}}
-Building a storeroom is one of the first things that a colony should do, as the destruction of required resources and equipment only slows progress and creates more work. But the effects of deterioration can also be used to dispose of junk without having to spend resources or pawn time to do so. Hauling corpses to a [[stockpile zone]] in running water, outdoors and unroofed will fairly rapidly get rid of them with no more work.
-Additionally understanding what items need to be protected is also important. Many raw resources don't deteriorate and thus can be kept outside without fear, buildings can as well but have a greater risk of being stolen by raiders. As it takes resources and time to build enclose warehouses, having layers of storage areas is helpful.
-== Version history==
-* ? - Deterioration no longer lowers the effectiveness of weapons and armors.
-*  Beta 19/1.0 - Item deterioration rate now takes into account several factors, including being outdoors, being unroofed, and being in water
