+
+This mod implements the ability of registering armors.
+
+## Registering an Armor Set
+
+The `mcl_armor.register_set()` function aims to simplify the process of registering a full set of armor.
+
+This function register four pieces of armor (head, torso, leggings, feets) based on a definition table:
+
+```lua
+mcl_armor.register_set({
+	--name of the armor material (used for generating itemstrings)
+	name = "dummy_armor",
+
+	--description of the armor material
+	--do NOT translate this string, it will be concatenated will each piece of armor's description and result will be automatically fetched from your mod's translation files
+	description = "Dummy Armor",
+
+	--overide description of each armor piece
+	--do NOT localize this string
+	descriptions = {
+		head = "Cap",    --default: "Helmet"
+		torso = "Tunic", --default: "Chestplate"
+		legs = "Pants",  --default: "Leggings"
+		feet = "Shoes",  --default: "Boots"
+	},
+
+	--this is used to calculate each armor piece durability with the minecraft algorithm
+	--head durability = durability * 0.6857 + 1
+	--torso durability = durability * 1.0 + 1
+	--legs durability = durability * 0.9375 + 1
+	--feet durability = durability * 0.8125 + 1
+	durability = 80,
+
+	--this is used then you need to specify the durability of each piece of armor
+	--this field have the priority over the durability one
+	--if the durability of some pieces of armor isn't specified in this field, the durability field will be used insteed
+	durabilities = {
+		head = 200,
+		torso = 500,
+		legs = 400,
+		feet = 300,
+	},
+
+	--this define how good enchants you will get then enchanting one piece of the armor in an enchanting table
+	--if set to zero or nil, the armor will not be enchantable
+	enchantability = 15,
+
+	--this define how much each piece of armor protect the player
+	--these points will be shown in the HUD (chestplate bar above the health bar)
+	points = {
+		head = 1,
+		torso = 3,
+		legs = 2,
+		feet = 1,
+	},
+
+	--this attribute reduce strong damage even more
+	--See https://minecraft.fandom.com/wiki/Armor#Armor_toughness for more explanations
+	--default: 0

+
+	--this field is used to specify some items groups that will be added to each piece of armor
+	--please note that some groups do NOT need to be added by hand, because they are already handeled by the register function:
+	--(armor, combat_armor, armor_<element>, combat_armor_<element>, mcl_armor_points, mcl_armor_toughness, mcl_armor_uses, enchantability)
+	groups = {op_armor = 1},
+
+	--specify textures that will be overlayed on the entity wearing the armor
+	--these fields have default values and its recommanded to keep the code clean by just using the default name for your textures
+	textures = {
+		head = "dummy_texture.png",  --default: "<modname>_helmet_<material>.png"
+		torso = "dummy_texture.png", --default: "<modname>_chestplate_<material>.png"
+		legs = "dummy_texture.png",  --default: "<modname>_leggings_<material>.png"
+		feet = "dummy_texture.png",  --default: "<modname>_boots_<material>.png"
+	},
+	--you can also define these fields as functions, that will be called each time the API function mcl_armor.update(obj) is called (every time you equip/unequip some armor piece, take damage, and more)
+	--note that the enchanting overlay will not appear unless you implement it in the function
+	--this allow to make armors where the textures change whitout needing to register many other armors with different textures
+	textures = {
+		head = function(obj, itemstack)
+			if mcl_enchanting.is_enchanted(itemstack) then
+				return "dummy_texture.png^"..mcl_enchanting.overlay
+			else
+				return "dummy_texture.png"
+			end
+		end,
+	},
+
+	--inventory textures aren't definable using a table similar to textures or previews

+	--legs: "<modname>_inv_leggings_<material>.png
+	--feet: "<modname>_inv_boots_<material>.png
+
+	--this callback table allow you to define functions that will be called each time an entity equip an armor piece or the mcl_armor.on_equip() function is called
+	--the functions accept two arguments: obj and itemstack
+	on_equip_callbacks = {
+		head = function(obj, itemstack)
+			--do stuff
+		end,
+	},
+

+		head = function(obj, itemstack)
+			--do stuff
+		end,
+	},
+
+	--this callback table allow you to define functions that will be called then an armor piece break
+	--the functions accept one arguments: obj
+	--the itemstack isn't sended due to how minetest handle items which have a zero durability
+	on_break_callbacks = {
+		head = function(obj)

+	repair_material = "mcl_core:iron_ingot",

+```
+
+## Creating an Armor Piece
+
+If you don't want to register a full set of armor, then you will need to manually register your own single item.
+
+```lua
+minetest.register_tool("dummy_mod:random_armor", {
+	description = S("Random Armor"),
+
+	--these two item fields are used for ingame documentation
+	--the mcl_armor.longdesc and mcl_armor.usage vars contains the basic usage and purpose of a piece of armor
+	--these vars may not be enough for that you want to do, so you may add some extra informations like that:
+	--_doc_items_longdesc = mcl_armor.longdesc.." "..S("Some extra informations.")
+	_doc_items_longdesc = mcl_armor.longdesc,
+	_doc_items_usagehelp = mcl_armor.usage,
+
+	--this field is similar to any item definition in minetest
+	--it just set the image shown then the armor is dropped as an item or inside an inventory
+	inventory_image = "mcl_armor_inv_elytra.png",
+
+	--this field is used by minetest internally and also by some helper functions
+	--in order for the tool to be shown is the right creative inventory tab, the right groups should be added
+	--"mcl_armor_uses" is required to give your armor a durability
+	--in that case, the armor can be worn by 10 points before breaking
+	--if you want the armor to be enchantable, you should also add the "enchantability" group, with the highest number the better enchants you can apply
+	groups = {armor = 1, non_combat_armor = 1, armor_torso = 1, non_combat_torso = 1, mcl_armor_uses = 10},
+
+	--this table is used by minetest for seraching item specific sounds
+	--the _mcl_armor_equip and _mcl_armor_unequip are used by the armor implementation to play sounds on equip and unequip
+	--note that you don't need to provide any file extention
+	sounds = {
+		_mcl_armor_equip = "mcl_armor_equip_leather",
+		_mcl_armor_unequip = "mcl_armor_unequip_leather",
+	},
+
+	--these fields should be initialised like that in most cases
+	--mcl_armor.equip_on_use is a function that try to equip the piece of armor you have in hand inside the right armor slot if the slot is empty
+	on_place = mcl_armor.equip_on_use,
+	on_secondary_use = mcl_armor.equip_on_use,
+
+	--this field define that the tool is ACTUALLY an armor piece and in which armor slot you can put it
+	--it should be set to "head", "torso", "legs" or "feet"
+	_mcl_armor_element = "torso",
+
+
+	--this field is used to provide the texture that will be overlayed on the object (player or mob) skin
+	--this field can be a texture name or a function that will be called each time the mcl_armor.update(obj) function is called
+	--see the mcl_armor.register_set() documentation for more explanations
+	_mcl_armor_texture = "mcl_armor_elytra.png"
+
+	--callbacks
+	--see the mcl_armor.register_set() documentation for more explanations
+
+	_on_equip = function(obj, itemstack)
+	end,
+	_on_unequip = function(obj, itemstack)
+	end,
+	_on_break = function(obj)
+	end,
+})
+```
+
+## Interacting with Armor of an Entity
+
+Mods may want to interact with armor of an entity.
+
+Most global functions not described here may not be stable or may be for internal use only.
+
+You can equip a piece of armor on an entity inside a mod by using `mcl_armor.equip()`.
+
+```lua
+--itemstack: an itemstack containing the armor piece to equip
+--obj: the entity you want to equip the armor on
+--swap: boolean, force equiping the armor piece, even if the entity already have one of the same type
+mcl_armor.equip(itemstack, obj, swap)
+```
+
+You can update the entity apparence by using `mcl_armor.update()`.
+
+This function put the armor overlay on the object's base texture.
+If the object is player it will update his displayed armor points count in HUD.
+
+This function will work both on players and mobs.
+
+```lua
+--obj: the entity you want the apparence to be updated
+mcl_armor.update(obj)
+```
+
+## Handling Enchantments
+
+Armors can be enchanted in most cases.
+
+The enchanting part of MineClone2 is separated from the armor part, but closely linked.
+
+Existing armor enchantments in Minecraft improve most of the time how the armor protect the entity from damage.
+
+The `mcl_armor.register_protection_enchantment()` function aims to simplificate the creation of such enchants.
+
+```lua
+mcl_armor.register_protection_enchantment({
+	--this field is the id that will be used for registering enchanted book and store the enchant inside armor metadata.
+	--(his internal name)
+	id = "magic_protection",
+
+	--visible name of the enchant
+	--this field is used as the name of registered enchanted book and inside armor tooltip
+	--translation should be added
+	name = S("Magic Protection"),
+
+	--this field is used to know that the enchant currently do
+	--translation should be added
+	description = S("Reduces magic damage."),
+
+	--how many levels can the enchant have
+	--ex: 4 => I, II, III, IV
+	--default: 4
+	max_level = 4,
+
+	--which enchants this enchant will not be compatible with
+	--each of these values is a enchant id
+	incompatible = {blast_protection = true, fire_protection = true, projectile_protection = true},
+
+	--how much will the enchant consume from the enchantability group of the armor item
+	--default: 5
+	weight = 5,
+
+	--false => the enchant can be obtained in an enchanting table
+	--true => the enchant isn't obtainable in the enchanting table
+	--is true, you will probably need to implement some ways to obtain it
+	--even it the field is named "treasure", it will be no way to find it
+	--default: false
+	treasure = false,
+
+	--how much will damage be reduced
+	--see Minecraft Wiki for more informations
+	--https://minecraft.gamepedia.com/Armor#Damage_protection
+	--https://minecraft.gamepedia.com/Armor#Enchantments
+	factor = 1,
+
+	--restrict damage to one type
+	--allow the enchant to only protect of one type of damage
+	damage_type = "magic",
+
+	--restrict damage to one category
+	--allow to protect from many type of damage at once
+	--this is much less specific than damage_type and also much more customisable
+	--the "is_magic" flag is used in the "magic", "dragon_breath", "wither_skull" and "thorns" damage types
+	--you can checkout the mcl_damage source code for a list of availlable damage types and associated flags
+	--but be warned that mods can register additionnal damage types
+	damage_flag = "is_magic",
+})
+```
