Module:Item2

From Path of Exile Wiki
Jump to: navigation, search

The item module provides functionality for various item-related templates.

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,

-- SMW reworked item module

-- ----------------------------------------------------------------------------
-- TODO
-- ----------------------------------------------------------------------------
-- Items
-- -----
-- Check if abyss jewels actually have radius modifiers
-- 
-- Aggregate ids from skill id from modifiers
-- 
-- DROP restriction improvements:
--  drop monster type(s)
--
-- unique items:
--  3D art
--  supporter attribution
--
-- Maps: 
--  Area level can be retrieved eventually
--
-- Essence: 
--  type column
--  monster modifier info
--
-- random modifier
-- -> sell price must consider random mods
-- ----------
-- Item class
-- ----------
--
-- remove the ul if name_list is not provided
-- maybe smw
