Module:Item2

Module documentation[view] [edit] [history] [purge]

This module is used on 13,000+ pages.

To avoid major disruption and server load, do not make unnecessary edits to this module. Test changes to this module first using its /sandbox and /testcases subpages . All of the changes can then be applied to this module in a single edit.

Consider discussing changes on the talk page or on Discord before implementing them.

This module depends on the following other modules:

• Module:No globals
• Module:Util
• Module:Cargo
• Module:Game
• Module:Item util
• Module:Skill
• Module:Item link
• Module:Area
• Module:Item2/recipes
• Module:Item2/cargo
• Module:Item2/config
• Module:Item2/core

The module implements {{item}}.

Overview

This module is responsible for creating item boxes, various item lists, item links and other item-related tasks. In the process a lot of the input data is verified and also added as semantic property to pages; as such, any templates deriving from this module should not be used on user pages other then for temporary testing purposes.

This template is also backed by an export script in PyPoE which can be used to export item data from the game files which then can be used on the wiki. Use the export when possible. de:Modul:Item2 ru:Модуль:Item2

The above documentation is transcluded from Module:Item2/doc. (edit | history)
Editors can experiment in this module's sandbox (edit | diff) and testcases (edit | run) pages.

-- SMW reworked item module

-- ----------------------------------------------------------------------------
-- TODO
-- ----------------------------------------------------------------------------
-- Items
-- -----
-- Check if abyss jewels actually have radius modifiers
--
-- Has explicit mod ids (and others) changing order of values in the API.
-- 
-- Aggregate ids from Has granted skill id from modifiers
-- 
-- DROP restriction improvements:
--  drop monster type(s)
--
-- unique items:
--  3D art
--  supporter attribution
--  option to hide explicit mods or override text
--
-- singular for weapon class in infoboxes
-- 
--
-- Maps: 
--  Area level can be retrieved eventually
--
-- Essence: 
--  type column
--  monster modifier info
-- ----------
-- Item table
-- ----------
-- Skills need proper range values in their tables 
-- stat_column<i>_stat<j>_id -> make an lua pattern alternative
-- show drop area etc
--
-- ----------
-- Item class
-- ----------
--
-- remove the ul if name_list is not provided
-- maybe smw
-- -----------
-- rework todo
-- -----------
-- check unique map properties copy
-- REMOVED:
--  is_essence
-- RENAMED
--  essence_tier -> essence_level
-- release_version
