Module:Items

Lua module containing all sorts of functions for getting data on items. Pulls data from Module:GameData/data.
Some functions were split to submodules:
local p = {}

local SkillData = mw.loadData('Module:Skills/data')

local Shared = require('Module:Shared')
local Icons = require('Module:Icons')

  end

end

function p.getItem(name)
  local result = nil
  for i, item in pairs(ItemData) do
    if(item.name == name) then
      result = Shared.clone(item)
      --Make sure every item has an id, and account for Lua being 1-index
      result.id = i -1
    end
  end
  return result
end
