LuaOTB

This is a small items.otb program for read/write and is compatible with TFS master written in Python and packaged with pyinstaller to make it portable.

Only works on Windows x64

Usage

Prepare your main.lua file for the task you need and then run LuaOTB.exe

Read and Write - Header

How to open an OTB file?

local otb = OTB()
otb:load("items.otb")

print(otb.majorVersion)
print(otb.minorVersion)
print(otb.buildVersion)
print(otb.description)

The console output should look something like this:

You can also modify these variables to customize the file header:

local otb = OTB()
otb:load("items.otb")

otb.minorVersion = 10
otb.majorVersion = 20
otb.buildVersion = 1
otb.description = "My Custom OTB"

otb:save("items_out.otb")

How to see if the changes happened?

local otb = OTB()
otb:load("items_out.otb")

print(otb.minorVersion)
print(otb.majorVersion)
print(otb.buildVersion)
print(otb.description)

Read and Write - ItemTypes

How to find an item to review or modify it?

local otb = OTB()
otb:load("items.otb")

local itemType = otb:getItemType(2160)
print(itemType)

-- modify the item
itemType.NAME = "My new name"
itemType.CLIENT_ID = 6666

otb:save("items_out.otb")

The console output should look something like this:

You should also see a new items_out.otb file in the directory.

How to know if the new file actually has the changes?

You can open the new OTB and review it.

local otb = OTB()
otb:load("items_out.otb")

local itemType = otb:getItemType(2160)
print(itemType)

The console output should look something like this:

How to add new items or maybe remove them?

local otb = OTB()
otb:load("items_out.otb")

local itemType = ItemType()
itemType.GROUP = 1
itemType.FLAGS = 0
itemType.NAME = "My new item"
itemType.SERVER_ID = 6666
itemType.CLIENT_ID = 6666

otb:addItemType(itemType)
otb:save("items_out.otb")

To remove them you can use the method removeItemType

local otb = OTB()
otb:load("items_out.otb")

otb:removeItemType(2160)
otb:save("items_out.otb")

How to know the count of items?

local otb = OTB()
otb:load("items_out.otb")

print(otb:getItemTypesCount())

How to iterate over all items?

local otb = OTB()
otb:load("items_out.otb")

local items = {}
for itemType in python.iter(otb.itemTypes) do
	if itemType.GROUP == 1 then
		items[#items + 1] = itemType
	end
end

print(string.format("Found %d items", #items))
